Field-Programmable Microcontroller Peripheral
1.0 Introduction
The low cost PSD3XX family integrates high-performance and user-configurable blocks of EPROM, programmable logic, and optional SRAM into one part. The PSD3XX products also provide a powerful microcontroller interface that eliminates the need for external "glue logic". The part's integration, small form factor, low power consumption, and ease of use make it the ideal part for interfacing to virtually any microcontroller. The major functional blocks of the PSD3XX include: * Two programmable logic arrays * 256Kb to 1 Mb of EPROM * Optional 16 Kb SRAM * Input latches * Programmable I/O ports * Page logic * Programmable security.
The PSD3XX family architecture (Figure 1) can efficiently interface with, and enhance, almost any 8- or 16-bit microcontroller system. This solution provides microcontrollers the following: * Chip-select logic, control logic, and latched address signals that are otherwise implemented discretely * Port expansion (reconstructs lost microcontroller I/O) * Expanded microcontroller address space (up to 16 times) * An EPROM (with security) and optional SRAM * Compatible with 8031-type architectures that use separate Program and Data Space * Interface to shared external resources.

7.0 ZPSD Background
Portable and battery-powered systems have recently become major embedded control application segments. As a result, the demand for electronic components having extremely low power consumption has increased dramatically. Recognizing this trend, WSI, Inc. developed a new lower power 3XX part, denoted ZPSD3XX. The Z stands for Zero-power because ZPSD products virtually eliminate the DC component of power consumption, reducing it to standby levels. Virtual elimination of the DC component is the basis for the words "Zero-power" in the ZPSD name. ZPSD products also minimize the AC power component when the chip is changing states. The result is a programmable microcontroller peripheral family that replaces discrete circuit components, while drawing less power.

7.0 ZPSD Background
(cont.)
Integrated Power Management TM Operation
Upon each address or logic input change to the ZPSD, the device powers up from low power standby for a short time. Then the ZPSD consumes only the necessary power to deliver new logic or memory data to its outputs as a response to the input change. After the new outputs are stable, the ZPSD latches them and automatically reverts back to standby mode. The ICC current flowing during standby mode and during DC operation is identical and is only a few microamperes. The ZPSD automatically reduces its DC current drain to these low levels and does not require controlling by the CSI (Chip Select Input). Disabling the CSI pin unconditionally forces the ZPSD to standby mode independent of other input transitions. The only significant power consumption in the ZPSD occurs during AC operation. The ZPSD contains the first architecture to apply zero power techniques to memory and logic blocks. Figure 2 compares ZPSD zero power operation to the operation of a discrete solution. A standard microcontroller (MCU) bus cycle usually starts with an ALE (or AS) pulse and the generation of an address. The ZPSD detects the address transition and powers up for a short time. The ZPSD then latches the outputs of the PAD, EPROM and SRAM to the new values. After finishing these operations, the ZPSD shuts off its internal power, entering standby mode. The time taken for the entire cycle is less than the ZPSD's "access time." The ZPSD will stay in standby mode while its inputs are not changing between bus cycles. In an alternate system implementation using discrete EPROM, SRAM, and other discrete components, the system will consume operating power during the entire bus cycle. This is because the chip select inputs on the memory devices are usually active throughout the entire cycle. The AC power consumption of the ZPSD may be calculated using the composite frequency of the MCU address and control signals, as well as any other logic inputs to the ZPSD.

Description
When the data bus is 8 bits: This pin is for 8031 or compatible MCUs that use PSEN to separate program space from data space. In this case, PSEN is used for reads from the EPROM. Note: if your MCU does not output a PSEN signal, pull up this pin to VCC. When the data bus is 16 bits: This pin is BHE. When low, D8-D15 are read from or written to. Note: in programming mode, this pin is pulsed between VPP and 0 V. The following control signals can be connected to this port, based on your MCU (and the way you configure the PSD in PSDsoft): 1. WR--active-low write pulse. 2. R/W--active-high read/active-low write input. Note: in programming mode, this pin must be tied to VPP. The following control signals can be connected to this port, based on your MCU (and the way you configure the PSD in PSDsoft): 1. RD--active-low read input. 2. E--E clock input. 3. DS--active-low data strobe input (3X2/3X3 devices only) The following control signals can be connected to this port: 1. CSI--Active-low chip select input. If your MCU supports a chip select output, and you want the PSD to save power when not selected, use this pin as a chip select input. 2. If you don't wish to use the CSI feature, you may use this pin as an additional input (logic or address) to the PAD. A19 can be latched (with ALE/AS), or a transparent logic input. PSD3XX/ZPSD3XX: This pin is user-programmable and can be configured to reset on a high- or low-level input. Reset must be applied for at least 100 ns.

ZPSD3XXV: This pin is not configurable, and the chip will only reset on an active-low level input. Reset must be applied for at least 500 ns, and no operations may take place for an additional 500 ns minimum. (See Figure 8.) If you use an MCU that has a multiplexed bus: Connect ALE or AS to this pin. The polarity of this pin is configurable. The trailing edge of ALE/AS latches all multiplexed address inputs (and BHE where applicable). If you use an MCU that does not have a multiplexed bus: If your MCU uses ALE/AS, connect the signal to this pin. Otherwise, use this pin for a generic logic input to the PAD. (Non-3X1 devices only.) These pins make up Port A. These port pins are configurable, and can have the following functions: (see Figure 5A and 5B) 1. Track AD7-AD0. This feature repeats the MCU address and data bus on all Port A pins. 2. MCU I/O--in this mode, the direction of the pin is defined by its direction bit, which resides in the direction register. 3. Latched address output. 4. CMOS or open-drain output. 5. If your MCU is non-multiplexed: data bus input--connect your data bus (D0-7) to these pins. See Figure 3.

These pins make up Port B. These port pins are configurable, and can have the following functions: (see Figure 6) 1. MCU I/O --in this mode, the direction of the pin is defined by its direction bit, which resides in the direction register. 2. Chip select output --each of PB0-3 has four product terms available per pin, while PB4-7 have 2 product terms each. See Figure 4. 3. CMOS or open-drain. 4. If your MCU is non-multiplexed, and the data bus width is 16 bits: data bus input--connect your data bus (D8-D15) to these pins. See Figure 3. These pins make up Port C. These port pins are configurable, and can have the following functions (see Figure 7): 1. PAD input--when configured as an input, a bit individually becomes an address or a logic input, depending on your PSDsoft design file. When declared as an address, the bit(s) can be latched with ALE/AS. 2. PAD output--when configured as an output (i.e. there is an equation written for it in your PSDsoft design file), there is one product term available to it. If your MCU is multiplexed: These pins are the multiplexed, low-order address/data byte (AD0-AD7). As inputs, address information is latched by the ALE/AS signal and used internally by the PSD. The pins also serve as MCU data bus inputs or outputs, depending on the MCU control signals (RD, WR, etc.). If your MCU is non-multiplexed: These pins are the low-order address inputs (A0-A7) If your MCU is multiplexed with a 16-bit data bus: These pins are the multiplexed, high-order address/data byte (AD8-AD15). As inputs, address information is latched by the ALE/AS signal and used internally the PSD. The pins also serve as MCU data bus inputs or outputs, depending on the MCU control signals (RD, WR, etc.). If your MCU is non-multiplexed or has a 8-bit data bus: These pins are the high-order address inputs (A8-A15). Ground Pin Supply voltage input.

PSD3XX Family
8.0 Operating Modes (MCU Configurations)
The PSD3XX's four operating modes enable it to interface directly to most 8- and 16-bit microcontrollers with multiplexed and non-multiplexed address/data busses. The 16-bit modes are not available to some devices; see Table 1. The following are the four operating modes available:
t t t t
Multiplexed 8-bit address/data bus Multiplexed 16-bit address/data bus Non-multiplexed 8-bit data bus Non-multiplexed 16-bit data bus
Please read the section below that corresponds to your type of MCU. Then check the appropriate Figure (3A/3B/3C/3D) to determine your pin connections. Table 3 lists the Port connections in tabular form.
Multiplexed 8-bit address/data bus (Figure 3A) This mode is used to interface to microcontrollers with a multiplexed 8-bit data bus. Since the low-order address and data are multiplexed together, your MCU will output an ALE or AS signal. The PSD3XX contains a transparent latch to demultiplex the address/data lines internally. All you have to do is connect the ALE/AS signal and select 8-bit multiplexed bus mode in PSDsoft. If your MCU outputs more than 16 bits of address, and you wish to connect them to the PSD, connect A16-A18 to Port C and A19 to A19/CSI, where applicable. Multiplexed 16-bit address/data bus (Figure 3B) This mode is used to interface to microcontrollers with a multiplexed 16-bit data bus. Since the low address bytes and data are multiplexed together, your MCU will output an ALE or AS signal. The PSD3XX contains a transparent latch to demultiplex the address/data lines internally. All you have to do is connect the ALE/AS signal and select 8-bit multiplexed bus mode in PSDsoft. If your MCU outputs more than 16 bits of address, and you wish to connect them to the PSD, connect A16-A18 to Port C and A19 to A19/CSI, where applicable. Non-multiplexed 8-bit data bus (Figure 3C) This mode is used to interface to microcontrollers with a non-multiplexed 8-bit data bus. Connect the MCU's address bus to AD0/A0-AD15/A15 on the PSD. Connect the data bus signals of your MCU to Port A of the PSD. If your MCU outputs more than 16 bits of address, and you wish to connect them to the PSD, connect A16-A18 to Port C and A19 to A19/CSI, where applicable. Non-multiplexed 16-bit data bus (Figure 3D) This mode is used to interface to microcontrollers with a non-multiplexed 16-bit data bus. Connect the MCU's address bus to AD0/A0-AD15/A15 on the PSD. Connect the low byte data bus signals of your MCU to Port A, and the high byte data output of your MCU to Port B of the PSD. If your MCU outputs more than 16 bits of address, and you wish to connect them to the PSD, connect A16-A18 to Port C and A19 to A19/CSI, where applicable.
For users with multiplexed MCUs that have data multiplexed on address lines other than A0-A7 note: You can still use the PSD3XX, but you will have to connect your data to Port A (and Port B where required), as shown in Figure 3C or 3D. That is, you will be connecting it as if you were using a non-multiplexed MCU. In this case, you must connect the ALE/AS signal so that the address will still be properly latched. This option is not available on the 3X1 versions.

9.0 Programmable Address Decoder (PAD)
The PSD3XX contains two programmable arrays, referred to as PAD A and PAD B (Figure 4). PAD A is used to generate chip select signals derived from the input address to the internal EPROM blocks, SRAM, I/O ports, and Track Mode signals. PAD B outputs to Ports B and C for off-chip usage. PAD B can also be used to extend the decoding to select external devices or as a random logic replacement. PAD A and PAD B receive the same inputs. The PAD logic is configured by PSDsoft based on the designer's input. The PAD's non-volatile configuration is stored in a re-programmable CMOS EPROM. Windowed packages are available for erasure by the user. See Table 4 for a list of PAD A and PAD B functions.

Function
PAD A and PAD B Inputs
A19/CSI When the PSD is configured to use CSI and while CSI is a logic 1, the PAD deselects all of its outputs and enters a power-down mode (see Tables 12 and 13). When the PSD is configured to use A19, this signal is another input to the PAD. These are general purpose inputs from Port C. See Figure 4, Note 3. These are address inputs. These are inputs from the page register (not available on 3X1 versions). This is the read pulse or strobe input. (DS not available on 3X1 versions). This is the write pulse or R/W select signal. This is the ALE or AS input to the chip. Use to demultiplex address and data. This deselects all outputs from the PAD; it can not be used in product term equations. See Tables 10 and 11. These are internal chip-selects to the 8 EPROM banks. Each bank can be located on any boundary that is a function of one product term of the PAD address inputs. This is an internal chip-select to the SRAM. Its base address location is a function of one term of the PAD address inputs. This internal chip-select selects the I/O ports. It can be placed on any boundary that is a function of one product term of the PAD inputs. See Tables 5A and 5B. This internal chip-select, when Port A is configured as a low-order address/data bus in the track mode controls the input direction of Port A. CSADIN is gated externally to the PAD by the internal read signal. When CSADIN and a read operation are active, data presented on Port A flows out of AD0/A0-AD7/A7. This chip-select can be placed on any boundary that is a function of one product term of the PAD inputs. See Figure 5B. This internal chip-select, when Port A is configured as a low-order address/data bus in track mode, controls the output direction of Port A. CSADOUT1 is gated externally to the PAD by the ALE signal. When CSADOUT1 and the ALE signal are active, the address presented on AD0/A0-AD7/A7 flows out of Port A. This chip-select can be placed on any boundary that is a function of one product term of the PAD inputs. See Figure 5B. This internal chip-select, when Port A is configured as a low-order address/data bus in the track mode, controls the output direction of Port A. CSADOUT2 must include the write-cycle control signals as part of its product term. When CSADOUT2 is active, the data presented on AD0/A0-AD7/A7 flows out of Port A. This chip-select can be placed on any boundary that is a function of one product term of the PAD inputs. See Figure 5B. These chip-select outputs can be routed through Port B. Each of them is a function of up to four product terms of the PAD inputs. These chip-select outputs can be routed through Port B. Each of them is a function of up to two product terms of the PAD inputs. These chip-select outputs can be routed through Port C. See Figure 4, Note 3. Each of them is a function of one product term of the PAD inputs.

10.0 I/O Port Functions
The PSD3XX has three I/O ports (Ports A, B, and C) that are configurable at the bit level. This permits great flexibility and a high degree of customization for specific applications. The next section describes the control registers for the ports. Following that are sections that describe each port. Figures 5 through 7 show the structure of Ports A through C, respectively. Note: any unused input should be connected directly to ground or pulled up to VCC (using a 10K to 100K resistor).
10.1 CSIOPORT Registers
Control of the ports is primarily handled through the CSIOPORT registers. There are 24 bytes in the address space, starting at the base address labeled CSIOPORT. Since the PSD3XX uses internal address lines A15-A8 for decoding, the CSIOPORT space will occupy 2 Kbytes of memory, on a 2 Kbyte boundary. This resolution can be improved to reduce wasted address space by connecting lower order address lines (A7 and below) to Port C. Using this method, resolution down to 256 Kbytes may be achieved. The CSIOPORT space must be defined in your PSDsoft design file. The following tables list the registers located in the CSIOPORT space.
16-Bit Users Note When referring to Table 5B, realize that Ports A and B are still accessible on a byte basis. Note: When accessing Port B on a 16-bit data bus, BHE must be low.

10.2 Port A (PA0-PA7)
The control registers of Port A are located in CSIOPORT space; see Table 5.
10.2.1 Port A (PA0-PA7) in Multiplexed Address/Data Mode Each pin of Port A can be individually configured. The following table summarizes what the control registers (in CSIOPORT space) for Port A do:
Register Name
Port A Pin Register Port A Direction Register Port A Data Register
0 Value
Sampled logic level at pin = `0' Pin is configured as input Data in DFF = `0'
1 Value
Sampled logic level at pin = `1' Pin is configured as output Data in DFF = `1'
Default Value
(Note 1)
X 0 0
NOTE: 1. Default value is the value after reset.
MCU I/O Mode The default configuration of Port A is MCU I/O. In this mode, every pin can be set (at runtime) as an input or output by writing to the respective pin's direction flip-flop (DIR FF, Figure 5A). As an output, the pin level can be controlled by writing to the respective pin's data flip-flop (DFF, Figure 5A). The Pin Register can be read to determine logic level of the pin. The contents of the Pin Register indicate the true state of the PSD driving the pin through the DFF or an external source driving the pin. Pins can be configured as CMOS or open-drain using WSI's PSDsoft software. Open-drain pins require external pull-up resistors. Latched Address Output Mode Alternatively, any bit(s) of Port A can be configured to output low-order demultiplexed address bus bit. The address is provided by the internal PSD address latch, which latches the address on the trailing edge of ALE/AS. Port A then outputs the desired demultiplexed address bits. This feature can eliminate the need for an external latch (for example: 74LS373) if you have devices that require low-order latched address bits. Although any pin of Port A may output an address signal, the pin is position-dependent. In other words, pin PA0 of Port A may only pass A0, PA1 only A1, and so on. Track Mode Track Mode sets the entire port to track the signals on AD0/A0-AD7/A7, depending on specific address ranges defined by the PAD's CSADIN, CSADOUT1, and CSADOUT2 signals. This feature lets the user interface the microcontroller to shared external resources without requiring external buffers and decoders. In Track Mode, Port A effectively operates as a bi-directional buffer, allowing external MCUs or host processors to access the local data bus. Keep the following information in mind when setting up Track Mode: t The direction is controlled by: * ALE/AS * RD/E or RD/E/DS (DS on non-3X1 devices only) * WR or R/W * PAD outputs CSADOUT1, CSADOUT2, and CSADIN defined in PSDsoft design. t When CSADOUT1 and ALE/AS are true, the address on AD0/A0-AD7/A7 is output on Port A. Note: carefully check the generation of CSADOUT1 to ensure that it is stable during the ALE/AS pulse. t When CSADOUT2 is active and a write operation is performed, the data on the AD0/A0-AD7/A7 input pins flows out through Port A. t When CSADIN is active and a read operation is performed, the data on Port A flows out through the AD0/A0-AD7/A7 pins. t Port A is tri-stated when none of the above conditions exist. 16

10.3 Port B (PB0-PB7)
The control registers of Port B are located in CSIOPORT space; see Table 5A and 5B.
10.3.1 Port B (PB0-PB7) in Multiplexed Address/Data Mode Each pin of Port B can be individually configured. The following table summarizes what the control registers (in CSIOPORT space) for Port B do:

NOTE: 1. Default value is the value after reset.
MCU I/O Mode The default configuration of Port B is MCU I/O. In this mode, every pin can be set (at run-time) as an input or output by writing to the respective pin's direction flip-flop (DIR FF, Figure 6). As an output, the pin level can be controlled by writing to the respective pin's data flip-flop (DFF, Figure 6). The Pin Register can be read to determine logic level of the pin. The contents of the Pin Register indicate the true state of the PSD driving the pin through the DFF or an external source driving the pin. Pins can be configured as CMOS or open-drain using WSI's PSDsoft software. Open-drain pins require external pull-up resistors. Chip Select Output Alternatively, each bit of Port B can be configured to provide a chip-select output signal from PAD B. PB0-PB7 can provide CS0-CS7, respectively. The functionality of these pins is not limited to chip selects only; they can be used for generic combinatorial logic as well. Each of the CS0-CS3 signals is comprised of four product terms, and each of the CS4-CS7 signals is comprised of two product terms.

10.4 Port C (PC0-PC2) Each pin of Port C (Figure 7) can be configured as an input to PAD A and PAD B, or as an output from PAD B. As inputs, the pins are referenced as A16-A18. Although the pins are given this reference, they can be used for any address or logic input. [For example, A8-A10 could be connected to those pins to improve the resolution (boundaries) of CS0-CS7 to 256 bytes.] How they are defined in the PSDsoft design file determines:
* Whether they are address or logic inputs * Whether the input is transparent or latched by the trailing edge of ALE/AS.
Notes: 1) If the inputs are addresses, they are routed to PAD A and PAD B, and can be used in any or all PAD equations. 2) A logic input is routed to PAD B and can be used for Boolean equations that are implemented in any or all of the CS0-CS10 PAD B outputs. Alternately, PC0-PC2 can become CS8-CS10 outputs, respectively, providing the user with more external chip-select PAD outputs. Each of the signals (CS8-CS10) is comprised of one product term.

PSD3XX Family
11. PSD Memory
The following sections explain the various memory blocks and memory options within the PSD3XX.
11.1 EPROM For all of the PSD3XX devices, the EPROM is built using Zero-power technology. This means that the EPROM powers up only when the address changes. It consumes power for the necessary time to latch data on its outputs. After this, it powers down and remains in Standby Mode until the next address change. This happens automatically, and the designer has to do nothing special.
The EPROM is divided into eight equal-sized banks. Each bank can be placed in any address location by programming the PAD. Bank0-Bank7 are selected by PAD A outputs ES0-ES7, respectively. There is one product term for each bank select (ESi). Refer to Table 1 to see the size of the EPROM for each PSD device.
11.2 SRAM (Optional) Like the EPROM, the optional SRAM in the PSD3XX devices is built using Zero-power technology.
All PSD3XX parts which do not have an R suffix contain 2 Kbytes of SRAM (Table 1). The SRAM is selected by the RS0 output of the PAD. There is one product term dedicated to RS0. If your design requires a SRAM larger than 2K x 8, then use one of the RAMless (R versions) of the 3XX devices with an external SRAM. The external SRAM can be addressed trhough Port A and all require logic will be taken care of by the PSD3XXR.
11.3 Page Register (Optional) All PSD3XX parts, except 3X1devices, have a four-bit page register. Thus the effective address space of your MCU can be enlarged by a factor of 16. Each bit of the Page Register can be individually read or written. The Page Register is located in CSIOPORT space (at offset 18h); see Table 5. The Page Register is connected to the lowest nibble of the data bus (D3-D0). The outputs of the Page Register, P3-P0, are connected to PAD A, and therefor can be used in any chip select (internal or external) equations. The contents of the page register are reset to zero at power-up and after any chip-level reset. 11.4 Programming and Erasure Programming the device can be done using the following methods: * WSI's main programmer--PSDpro--which is accessible through a parallel port. * WSI's programmer used specifically with the PSD3XX--PEP300. * WSI's discontinued programmer--Magic Pro. * A 3rd party programmer, such as Data I/O. Information for programming the device is available directly from WSI. Please contact your local sales representative. Also, check our web site (waferscale.com) for information related to 3rd party programmers.
Upon delivery from WSI, or after each erasure (using windowed part), the PSD3XX device has all bits in PAD and EPROM in the HI state (logic 1). The configuration bits are in the LO state (logic 0). To clear all locations of their programmed contents (assuming you have a windowed version), expose the windowed device to an Ultra-Violet (UV) light source. A dosage of 30 W second/cm2 is required for PSD3XX devices, and 40 W second/cm2 for low-voltage (V suffix) devices. This dosage can be obtained with exposure to a wavelength of 2537 A and intensity of 12000 W/cm2 for 40 to 45 minutes for the PSD3XX and 55 to 60 minutes for the low-voltage (V suffix) devices. The device should be approximately 1 inch (2.54 cm) from the source, and all filters should be removed from the UV light source prior to erasure. The PSD3XX devices will erase with light sources having wavelengths shorter than 4000 A. However, the erasure times will be much longer than when using the recommended 2537 A wavelength. Note: exposure to sunlight will eventually erase the device. If used in such an environment, the package window should be covered with an opaque substance.

12.0 Control Signals
Consult your MCU data sheet to determine which control signals your MCU generates, and how they operate. This section is intended to show which control signals should be connected to what pins on the PSD3XX. You will then use PSDsoft to configure the PSD3XX, based on the combination of control signals that your MCU outputs, for example RD, WR, and PSEN. The PSD3XX is compatible with the following control signals: * ALE or AS (polarity is programmable) * WR or R/W * RD/E or RD/E/DS (DS for non-3X1 devices only) * BHE or PSEN * A19/CSI * RESET (polarity is programmable except on low voltage versions with the V suffix).
12.1 ALE or AS
Connect the ALE or AS signal from your MCU to this pin where applicable, and program the polarity using PSDsoft. The trailing edge (when the signal goes inactive) of ALE or AS latches the address on any pins that have an address input. If you are using a non-multiplexed-bus MCU that does not output an ALE or AS signal, this pin can be used for a generic input to the PAD. Note: if your data is multiplexed with address lines other than A0-A7, connect your address pins to AD0/A0-AD15/A15, and connect your data to Port A (and Port B where applicable), and connect the ALE/AS signal to this pin.
12.2 WR or R/W
Your MCU should output a stand-alone write signal (WR) or a multiplexed read/write signal (R/W). In either case, the signal should be connected to this pin.
12.3 RD/E/DS (DS option not available on 3X1 devices)
Your MCU should output any one of RD, E (clock), or DS. In any case, connect the appropriate signal to this pin.
12.4 BHE or PSEN t If your MCU does not output either of these signals, tie this pin to Vcc
(through a series resistor), and skip to the next signal.
t If you use an 8-bit 8031 compatible MCU that outputs a separate signal when
accessing program space, such as PSEN, connect it to this pin. You would then use PSDsoft to configure the EPROM in the PSD3XX to respond to PSEN only or PSEN and RD. If you have an 8031 compatible MCU, refer to the "Program/Data Space and the 8031" section for further information.
t If you are using a 16-bit MCU, connect the BHE (or similar signal) output to this pin.
BHE enables accessing of the upper byte of the data bus. See Table 6 for information on how this signal is used in conjunction with the A0 address line.

12.5 A19/CSI
This pin is configured using PSDsoft to be either a chip select for the entire PSD device or an additional PAD input. If your MCU can generate a chip-select signal, and you wish to save power, use the PSD chip select feature. Otherwise, use this pin as an address or logic input.
t When configured as CSI (active-low PSD chip select): a low on this pin keeps the PSD
in normal operation. However, when a high is detected on the pin, the PSD enters Power-down Mode. See Tables 7A and 7B for information on signal states during Power-down Mode. See section 16 for details about the reduction of power consumption.
t When configured as A19, the pin can be used as an additional input to the PADs.
It can be used for address or logic. It can also be ALE/AS dependent or a transparent input, which is determined by your PSDsoft design file. In A19 mode, the PSD is always enabled.

12.6 Reset Input
This is an asynchronous input to initialize the PSD device. Refer to tables 8A and 8B for information on device status during and after reset. The standard-voltage PSD3XX and ZPSD3XX (non-V) devices require a reset input that is asserted for at least 100 nsec. The PSD will be functional immediately after reset is de-asserted. For these standard-voltage devices, the polarity of the reset input signal is programmable using PSDsoft (active-high or active-low), to match the functionality of your MCU reset. Note: It is not recommended to drive the reset input of the MCU and the reset input of the PSD with a simple RC circuit between power on ground. The input threshold of the MCU and the PSD devices may differ, causing the devices to enter and exit reset at different times because of slow ramping of the signal. This may result in the PSD not being operational when accessed by the MCU. It is recommended to drive both devices actively. A supervisory device or a gate with hysteresis is recommended. For low-voltage ZPSD3XXV devices only, the reset input must be asserted for at least 500 nsec. The ZPSD3XXV will not be functional for an additional 500 nsec after reset is de-asserted (see Figure 8). These low voltage ZPSD3XXV devices must use an active-low polarity signal for reset. Unlike the standard PSDs, the reset polarity for the ZPSD3XXV is not programmable. If your MCU operates with an active high reset, you must invert this signal before driving the ZPSD3XXV reset input. You must design your system to ensure that the PSD comes out of reset and the PSD is active before the MCU makes its first access to PSD memory. Depending on the characteristics and speed of your MCU, a delay between the PSD reset and the MCU reset may be needed.

This section only applies to users who have an 8031 or compatible MCU that outputs a signal such as PSEN when accessing program space. If this applies to you, be aware of the following:
t The PSD3XX can be configured using PSDsoft such that the EPROM is either
1) accessed by PSEN only (Figure 10); or 2) accessed by PSEN or RD (Figure 9). The default is PSEN only unless changed in PSDsoft.
t The SRAM and I/O Ports (including CSIOPORT) can not be placed in program space
only. By default, they are in data space only (Figure 10). However, the SRAM may be placed in Program and Data Space, as shown in Figure 9.

In Figure 11, the PSD3XX is configured to interface with Intel's 80C31, which is a 16-bit address/8-bit data bus microcontroller. Its data bus is multiplexed with the low-order address byte. The 80C31 uses signals RD to read from data memory and PSEN to read from code memory. It uses WR to write into the data memory. It also uses active high reset and ALE signals. The rest of the configuration bits, as well as the unconnected signals, are application specific, and thus, user dependent.

In Figure 13, the PSD3XX is configured to work directly with Intel's 80C196KB microcontroller, which is a 16-bit address/16-bit data bus processor. The Address and data lines multiplexed. The PSD3XX is configured to use PC0, PC1, PC2, and A19/CSI as logic inputs. These signals are independent of the ALE pulse (latch-transparent). They are used as four general-purpose inputs that take part in the PAD equations. Port A is configured to work in Track Mode, in which (for certain conditions) PA0-PA7 tracks lines AD0/A0-AD7/A7. Port B is configured to generate CS0-CS7. In this example, PB2 serves as a WAIT signal that slows down the 80C196KB during the access of external peripherals. These 8-bit wide peripherals are connected to the shared bus of Port A. The WAIT signal also drives the buswidth input of the microcontroller, so that every external peripheral cycle becomes an 8-bit data bus cycle. PB3 and PB4 are open-drain output signals; thus, they are pulled up externally.

PSD3XX Family
15.0 Security Mode
Security Mode in the PSD3XX locks the contents of PAD A, PAD B, and all the configuration bits. The EPROM, optional SRAM, and I/O contents can be accessed only through the PAD. The Security Mode must be set by PSDsoft prior to run-time. The Security Bit can only be erased on the UV parts using a full-chip erase. If Security Mode is enabled, the contents of the PSD3XX can not be uploaded (copied) on a device programmer.
16.0 Power Management
PSDs from all PSD3XX families use Zero-power memory techniques that place memory into Standby Mode between MCU accesses. The memory becomes active briefly after an address transition, then delivers new data to the outputs, latches the outputs, and returns to Standby. This is done automatically and the designer has to do nothing special to benefit from this feature. In addition to the benefits of Zero-power memory technology, there are ways to gain additional savings. The following factors determine how much current the entire PSD device uses: * Use of CSI (Chip Select Input) * Setting of the CMiser bit * Setting of the Turbo Bit (ZPSD only) * The number of product terms used in the PAD * The composite frequency of the input signals to the PAD * The loading on I/O pins. The total current consumption for the PSD is calculated by summing the currents from memory, PAD logic, and I/O pins, based on your design parameters and the power management options used.
16.1 CSI Input
Driving the CSI pin inactive (logic 1) disables the inputs of the PSD and forces the entire PSD to enter Power-down Mode, independent of any transition on the MCU bus (address and control) or other PSD inputs. During this time, the PSD device draws only standby current (micro-amps). Alternately, driving a logic 0 on the CSI pin returns the PSD to normal operation. See Tables 7A and 7B for information on signal states during Power-down Mode. The CSI pin feature is available only if enabled in the PSDsoft Configuration utility.
16.2 CMiser bit
In addition to power savings resulting from the Zero-power technology used in the memory, the CMiser feature saves even more power under certain conditions. Savings are significant when the PSD is configured for an 8-bit data path because the CMiser feature turns off half of the array when memory is being accessed (the memory is divided internally into odd and even arrays). See the DC characteristics table for current usage related to the CMiser bit. You should keep the following in mind when using this bit: * Setting of this bit is accomplished with PSDsoft at the design stage, prior to run-time. * Memory access times are extended by 10 nsec for standard voltage (non-V) devices, and 20 nsec for low voltage (V) devices. * EPROM access: although CMiser offers significant power savings in 8-bit mode (~50%), CMiser contributes no additional power savings when the PSD is configured for 16-bits. * SRAM access: CMiser reduces power consumption of PSDs configured for either 8-bit or 16-bit operation.

16.3 Turbo Bit (ZPSD only)
The turbo bit is controlled by the MCU at run-time and is accessed through bit zero of the Power Management Register (PMR). The PMR is located in CSIOPORT space at offset 10h.

Bit 0 Turbo bit 1= OFF
*Future Configuration bits are reserved and should be set to one when writing to this register. The default value at reset of all bits in the PMR is logic 0, which means the Turbo feature is enabled. The PAD logic (PAD A and PAD B) of the PSD will operate at full speed and full power. When the Turbo Bit is set to logic 1, the Turbo feature is disabled. When disabled, the PAD logic will draw only standby current (micro-amps) while no PAD inputs change. Whenever there is a transition on any PAD input (including MCU address and control signals), the PAD logic will power up and will generate new outputs, latch those outputs, then go back to Standby Mode. Keep in mind that the signal propagation delay through the PAD logic increases by 10 nsec for non-V devices, and 20 nsec for V devices while in non-turbo mode. Use of the Turbo Bit does not affect the operation or power consumption of memory. Tremendous power savings are possible by setting the Turbo Bit and going into non-turbo mode. This essentially reduces the DC power consumption of the PAD logic to zero. It also reduces the AC power consumption of PAD logic when the composite frequency of all PAD inputs change at a rate less than 40 MHz for non-V devices, and less than 20 MHz for V devices. Use Figures 14 and 15 to calculate AC and DC current usage in the PAD with the Turbo Bit on and off. You will need to know the number of product terms that are used in your design and you will have to calculate the composite frequency of all signals entering the PAD logic.
16.4 Number of Product Terms in the PAD Logic
The number of product terms used in your design relates directly to how much current the PADs will draw. Therefore, minimizing this number will be in your best interest if power is a concern for you. Basically, the amount of product terms your design will use is based on the following (see Figure 4): * Each of the EPROM block selects, ES0-ES7 uses one product term (for a total of 8). * The CSIOPORT select uses one product term. * If your part has SRAM (non-R versions), the SRAM select RS0 uses one product term. * The Track Mode control signals (CSADIN, CSADOUT1, and CSADOUT2) each use one product term if you use these signals. * Port B, pins PB0-PB3 are allocated four product terms each if used as outputs. * Port B, pins PB4-PB7 are allocated two product terms each if used as outputs. * Port C, pins PC0-PC2 are allocated one product term each if used as outputs. Given the above product term allocation, keep the following points in mind when calculating the total number of product terms your design will require: 1) The EPROM block selects, CSIOPORT select, and SRAM select will use a product term whether you use these blocks or not. This means you start out with 10 product terms, and go up from there. 2) For Port B, if you use a pin as an output and your logic equation requires only one product term, you still have to include all the available product terms for that pin for power consumption, even though only one product term is specified. For example, if the output equation for pin PB0 uses just one product term, you will have to count PB0 as contributing four product terms to the overall count. With this in mind, you should use Port C for the outputs that only require one product term and PB4-7 for outputs that require two product terms. Use pins PB0-3 if you need outputs requiring more than two product terms or you have run out of outputs. 3) The following PSD functions do not consume product terms: MCU I/O mode, Latched Address Output, and PAD inputs (logic or address).

16.5 Composite Frequency of the Input Signals to the PAD Logic
The composite frequency of the input signals to the PADs is calculated by considering all transitions on any PAD input signal (including the MCU address and control inputs). Once you have calculated the composite frequency and know the number of product terms used, you can determine the total AC current consumption of the PAD by using Figure 14 or Figure 15. From the figures, notice that the DC component (f = 0 MHz) of PAD current is essentially zero when the turbo feature is disabled, and that the AC component increases as frequency increases. When the turbo feature is disabled, the PAD logic can achieve low power consumption by becoming active briefly, only when inputs change. For standard voltage (non-V) devices, the PAD logic will stay active for 25 nsec after it detects a transition on any input. If there are more transitions on any PAD input within the 25 nsec period, these transitions will not add to power consumption because the PAD logic is already active. This effect helps reduce the overall composite frequency value. In other words, narrowly spaced groups of transitions on input signals may count as just one transition when estimating the composite frequency. Note that the "knee" frequency in Figure 14 is 40 MHz, which means that the PAD will consume less power only if the composite frequency of all PAD inputs is less than 40 MHz. When the composite frequency is above 40 MHz, the PAD logic never gets a chance to shut down (inputs are spaced less than 25 nsec) and no power savings can be achieved. Figure 15 is for low-voltage devices in which the "knee" frequency is 20 MHz. Take the following steps to calculate the composite frequency: 1) Determine your highest frequency input for either PAD A or PAD B. 2) Calculate the period of this input and use this period as a basis for determining the composite frequency. 3) Examine the remaining PAD input signals within this base period to determine the number of distinct transitions. 4) Signal transitions that are spaced further than 25 nsec apart count as a distinct transition (50 nsec for low-voltage V devices). Signal transitions spaced closer than 25 nsec count as the same transition. 5) Count up the number of distinct transitions and divide that into the value of the base period. 6) The result is the period of the composite frequency. Divide into one to get the composite frequency value. Unfortunately, this procedure is complicated and usually not deterministic since different inputs may be changing in various cycles. Therefore, we recommend you think of the situation that has the most activity on the inputs to the PLD and use this to calculate the composite frequency. Then you will have a number that represents your best estimate at the worst case scenario. Since this is a complicated process, the following example should help.
Example Composite Frequency Calculation
Suppose you had the following circuit:
80C31 (12 MHz Crystal)
AD0-AD7 A8-A15 ALE RD WR PSEN CSI

(cont.)
All the inputs shown, except CSI, go to the PAD logic. These signals must be taken into consideration when calculating the composite frequency. Before we make the calculation, let's establish the following conditions: * The input with the highest frequency is ALE, which is 2 MHz. So our base period is 500 nsec for this example. * Only the address information from the multiplexed signals AD0-AD7 reach the PAD logic because of the internal address latch. Signal transitions from data on AD0-AD7 do not reach the PADs. * The three inputs (Int, Sel, or Rdy) change state very infrequently relative to the 80C31 bus signals. Now, lets assume the following is a snapshot in time of all the input signals during a typical 80C31 bus cycle. We'll use a code fetch as an example since that happens most often.
ONE TYPICAL 80C31 BUS CYCLE (2 MHz, 500 nsec)
ALE PSEN 1 AD0-AD7 A8-A15 INT SEL RDY 3 ADDR 2 DATA
< 25 nsec
FOUR DISTINCT TRANSITIONS
The calculation of the composite frequency is as follows: * There are four distinct transitions (first four dotted lines) within the base period of 500 nsec. These first four transitions all count toward the final composite frequency. * The transition at (1) in the diagram does not count as a distinct transition because it is within 25 nsec of a neighboring transition (use 50 nsec for a ZPSD3XXV device). * Transition (2) above does not add to the composite frequency because only the internally latched address signals reach the PADs, the data signal transitions do not. * The transition at (3) just happens to appear in this snapshot, but its frequency is so low that it is not a significant contributor to the overall composite frequency, and will not be used. * Divide the 500 nsec base period by the four (distinct transitions), yielding 125 nsec. 1/125 nsec = 8 MHz. * Use 8 MHz as the composite frequency of PAD inputs when calculating current consumption. (See the next section for a sample current calculation.)
16.6 Loading on I/O pins
A final consideration when calculating the current usage for the entire PSD device is the loading on I/O pins. All specifications for PSD current consumption in this document assume zero current flowing through PSD I/O pins (including ADIO). I/O current is dictated by the individual design implementation, and must be calculated by the designer. Be aware that I/O current is a function of loading on the pins and the frequency at which the signals toggle.

17. Calculating Power
Once you have read the "Power Management" section, you should be able to calculate power. The following is a sample power calculation:
Conditions

Calculation (Based on Typical AC and DC Currents)
ICC total = Istandby x % time CSI is high + [ICC (AC) + ICC (DC)] x % time CSI is low. = Istandby x % time CSI is high + [% EPROM Access x 0.8 mA/MHz x Freq. of ALE + % SRAM x 1.4 mA/MHz x Freq of ALE + ZPLD AC current (Figure 14: 13 PTs, 8 MHz, Non-Turbo)] x % time CSI is low = 10 A x 0.9 + (0.8 x 0.8 mA/MHz x 2 MHz + 0.15 x 1.4 mA/MHz x 2 MHz + 5.0 mA) x 0.1 = 9.0 A + (1.28 mA + 0.42 mA + 5.0 mA) x 0.1 = 679 A, based on the system operating in standby 90% of the time
NOTES: 1. 2. 3. 4. 5.
Calculation is based on the assumption that IOUT = 0 mA (no I/O pin loading) ICC(DC) is zero for all ZPSD devices operating in non-turbo mode. 13 product terms: 8 for EPROM, 3 for Chip Selects, 1 for SRAM, 1 for CSIOPORT. The 5% I/O access in the conditions section is when the MCU accesses CSIOPORT space. Standby Mode can also be achieved without using the CSI pin. The ZPSD device will automatically go into Standby while no inputs are changing on any pin, and Turbo Mode is disabled.

Notes for Timing Diagrams
1. Direct PAD input = any of the following direct PAD input lines: CSI/A19 as transparent A19, RD/E/DS, WR or R/W, transparent PC0-PC2, ALE in non-multiplexed modes. 2. Multiplexed inputs: any of the following inputs that are latched by the ALE (or AS): A0/AD0-A15/AD15, CSI/A19 as ALE dependent A19, ALE dependent PC0-PC2. 3. CSOi = any of the chip-select output signals coming through Port B (CS0-CS7) or through Port C (CS8-CS10). 4. CSADOUT1, which internally enables the address transfer to Port A, should be derived only from direct PAD input signals, otherwise the address propagation delay is slowed down. 5. CSADIN and CSADOUT2, which internally enable the data-in or data-out transfers, respectively, can be derived from any combination of direct PAD inputs and multiplexed PAD inputs. 6. The write operation signals are included in the CSOi expression. 7. Multiplexed PAD inputs: any of the following PAD inputs that are latched by the ALE (or AS) in the multiplexed modes: A11/AD11-A15/AD15, CSI/A19 as ALE dependent A19, ALE dependent PC0-PC2. 8. CSOi product terms can include any of the PAD input signals shown in Figure 3, except for reset and CSI.
