Host software issues commands and data to the NX2LP-Flex and receives status and data from the NX2LP-Flex using standard USB protocol. The default firmware image supports industry leading 8-bit NAND Flash interfaces and both common NAND page sizes of 512 and 2k bytes. Up to eight chip enable pins allow the NX2LP-Flex to be connected to up to eight single- or four dual-die NAND Flash chips. Complete source code and documentation for the default firmware image are included in the NX2LP-Flex development kit to enable customization for meeting design requirements. Additionally, compile options for the default firmware allow for quick configuration of some features to decrease design effort and increase time-to-market advantages. Overview Cypress Semiconductor Corporation's (Cypress's) EZ-USB NX2LP-Flex (CY7C68033/CY7C68034) is a firmware-based, programmable version of the EZ-USB NX2LPTM (CY7C68023/CY7C68024), which is a fixed-function, low-power USB 2.0 NAND Flash controller. By integrating the USB 2.0 transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip, Cypress has created a very cost-effective solution that enables feature-rich NAND Flash-based applications. The ingenious architecture of NX2LP-Flex results in USB data transfer rates of over 53 Mbytes per second, the maximum-allowable USB 2.0 bandwidth, while still using a low-cost 8051 microcontroller in a small 56-pin QFN package. Because it incorporates the USB 2.0 transceiver, the NX2LP-Flex is more economical, providing a smaller footprint solution than external USB 2.0 SIE or transceiver implementations. With EZ-USB NX2LP-Flex, the Cypress Smart SIE handles most of the USB 1.1 and 2.0 protocol, freeing the embedded microcontroller for application-specific functions and decreasing development time while ensuring USB compatibility. The General Programmable Interface (GPIF) and Master/Slave Endpoint FIFO (8- or 16-bit data bus) provide an easy and glueless interface to popular interfaces such as UTOPIA, EPP, I2C, PCMCIA, and most DSP processors. Applications The NX2LP-Flex allows designers to add extra functionality to basic NAND Flash mass storage designs, or to interface them with other peripheral devices. Applications may include: * NAND Flash-based GPS devices * NAND Flash-based DVB video capture devices * Wireless pointer/presenter tools with NAND Flash storage * NAND Flash-based MPEG/TV conversion devices * Legacy conversion devices with NAND Flash storage * NAND Flash-based cameras * NAND Flash mass storage device with biometric (e.g., fingerprint) security * Home PNA devices with NAND Flash storage * Wireless LAN with NAND Flash storage * NAND Flash-based MP3 players * LAN networking with NAND Flash storage Document #: 001-04247 Rev. *D Page 2 of 33 [+] Feedback CY7C68033/CY7C68034 Figure 1.

An on-chip PLL multiplies the 24-MHz oscillator up to 480 MHz, as required by the transceiver/PHY, and internal counters divide it down for use as the 8051 clock. The default 8051 clock frequency is 12 MHz. The clock frequency of the 8051 can be changed by the 8051 through the CPUCS register, dynamically Figure 3. Crystal Configuration. Figure 2.

Each reference design comes complete with firmware source and object code, schematics, and documentation. Please visit http://www.cypress.com for more information. Special Function Registers Certain 8051 SFR addresses are populated to provide fast access to critical NX2LP-Flex functions. These SFR additions are shown in Table 1. Bold type indicates non-standard, enhanced 8051 registers. The two SFR rows that end with `0' and `8' contain bit-addressable registers. The four I/O ports A-D use the SFR addresses used in the standard 8051 for ports 0-3, which are not implemented in NX2LP-Flex. Because of the faster and more efficient SFR addressing, the NX2LP-Flex I/O ports are not addressable in external RAM space (using the MOVX instruction). I2C Bus NX2LP supports the I2C bus as a master only at 100-/400-kHz. SCL and SDA pins have open-drain outputs and hysteresis inputs. These signals must be pulled up to 3.3V, even if no I2C device is connected. The I2C bus is disabled at startup and only available for use after the initial NAND access. Functional Overview USB Signaling Speed NX2LP-Flex operates at two of the three rates defined in the USB Specification Revision 2.0, dated April 27, 2000: * Full speed, with a signaling bit rate of 12 Mbps * High speed, with a signaling bit rate of 480 Mbps. NX2LP-Flex does not support the low-speed signaling mode of 1.5 Mbps. Document #: 001-04247 Rev. *D Page 3 of 33 [+] Feedback CY7C68033/CY7C68034 Table 1.

If valid firmware is found, the NX2LP-Flex loads it and operates according to the firmware. If no NAND Flash is detected, or if no valid firmware is found, the NX2LP-Flex uses the default values from internal ROM space for manufacturing mode operation. The two modes of operation are described in the section "Normal Operation Mode" on page 5 and "Manufacturing Mode" on page 5.

NX2LP-Flex Enumeration Sequence Start-up values stored in ROM space. The default silicon ID values should only be used for development purposes. Cypress requires designers to use their own Vendor ID for final products. A Vendor ID is obtained through registration with the USB Implementor's Forum (USB-IF). Also, if the NX2LP-Flex is used as a mass storage class device, a unique USB serial number is required for each device in order to comply with the USB Mass Storage class specification. Cypress provides all the software tools and drivers necessary for properly programming and testing the NX2LP-Flex. Please refer to the documentation in the development kit for more information on these topics. Table 2.

No NAND Flash Programmed? No Yes Load Firmware From NAND Load Default Descriptors and Configuration Data ReNumerationTM Cypress's ReNumerationTM feature is used in conjunction with the NX2LP-Flex manufacturing software tools to enable first-time NAND programming. It is only available when used in conjunction with the NX2LP-Flex Manufacturing tools, and is not enabled during normal operation. Bus-powered Applications Enumerate According To Firmware Enumerate As Unprogrammed NX2LP-Flex The NX2LP-Flex fully supports bus-powered designs by enumerating with less than 100 mA, as required by the USB 2.0 specification. Interrupt System INT2 Interrupt Request and Enable Registers Normal Operation Mode Manufacturing Mode NX2LP-Flex implements an autovector feature for INT2 and INT4. There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors. See the EZ-USB Technical Reference Manual (TRM) for more details. USB-Interrupt Autovectors The main USB interrupt is shared by 27 interrupt sources. To save the code and processing time that normally would be required to identify the individual USB interrupt source, the NX2LP-Flex provides a second level of interrupt vectoring, called Autovectoring. When a USB interrupt is asserted, the NX2LP-Flex pushes the program counter onto its stack then jumps to address 0x0500, where it expects to find a `jump' instruction to the USB Interrupt service routine. Developers familiar with Cypress's programmable USB devices should note that these interrupt vector values differ from those used in other EZ-USB microcontrollers. This is due to the additional NAND boot logic that is present in the NX2LP-Flex ROM space. Also, these values are fixed and cannot be changed in the firmware. Normal Operation Mode In Normal Operation Mode, the NX2LP-Flex behaves as a USB 2.0 Mass Storage Class NAND Flash controller. This includes all typical USB device states (powered, configured, etc.). The USB descriptors are returned according to the data stored in the configuration data memory area. Normal read and write access to the NAND Flash is available in this mode. Manufacturing Mode In Manufacturing Mode, the NX2LP-Flex enumerates using the default descriptors and configuration data that are stored in internal ROM space. This mode allows for first-time programming of the configuration data memory area, as well as board-level manufacturing tests.

The FIFO/GPIF Interrupt, like the USB Interrupt, can employ autovectoring. Table 4 shows the priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources. Notes If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP register), the NX2LP-Flex substitutes its INT2VEC byte. Therefore, if the high byte (`page') of a jump-table address is preloaded at location 0x544, the automatically-inserted INT2VEC byte at 0x545 will direct the jump to the correct address out of the 27 addresses within the page.

This reset period should be approximately 5 ms after VCC has reached 3.0V. If the crystal input pin is driven by a clock signal, the internal PLL stabilizes in 200 s after VCC has reached 3.0V[1]. Figure 5 shows a power-on reset condition and a reset applied during operation. A power-on reset is defined as the time reset is asserted while power is being applied to the circuit. A powered reset is defined to be when the NX2LP-Flex has previously been powered on and operating and the RESET# pin is asserted. Cypress provides an application note which describes and recommends power on reset implementation and can be found on the Cypress web site. For more information on reset implementation for the EZ-USB family of products visit the http://www.cypress.com website. If Autovectoring is enabled (AV4EN = 1 in the INTSET-UP register), the NX2LP-Flex substitutes its INT4VEC byte. Therefore, if the high byte (`page') of a jump-table address is preloaded at location 0x554, the automatically-inserted INT4VEC byte at 0x555 will direct the jump to the correct address out of the 14 addresses within the page. When the ISR occurs, the NX2LP-Flex pushes the program counter onto its stack then jumps to address 0x553, where it expects to find a `jump' instruction to the ISR Interrupt service routine. Reset and Wakeup Reset Pin The input pin RESET#, will reset the NX2LP-Flex when asserted. This pin has hysteresis and is active LOW. When a crystal is used as the clock source for the NX2LP-Flex, the Figure 5. Reset Timing Plots RESET# RESET# VIL 3.3V 3.0V VCC 0V TRESET Power-on Reset VIL 3.3V VCC 0V TRESET Powered Reset Note 1. If the external clock is powered at the same time as the CY7C68033/CY7C68034 and has a stabilization wait period, it must be added to the 200 s.

Reset Timing Values Condition Power-on Reset with crystal Power-on Reset with external clock source Powered Reset Wakeup Pins The 8051 puts itself and the rest of the chip into a power-down mode by setting PCON.0 = 1. This stops the oscillator and PLL. When WAKEUP is asserted by external logic, the oscillator restarts, after the PLL stabilizes, and then the 8051 receives a wakeup interrupt. This applies whether or not NX2LP-Flex is connected to the USB. The NX2LP-Flex exits the power-down (USB suspend) state using one of the following methods: * USB bus activity (if D+/D- lines are left floating, noise on these lines may indicate activity to the NX2LP-Flex and initiate a wakeup). * External logic asserts the WAKEUP pin * External logic asserts the PA3/WU2 pin. The second wakeup pin, WU2, can also be configured as a general purpose I/O pin. This allows a simple external R-C network to be used as a periodic wakeup source. Note that WAKEUP is, by default, active LOW. Program/Data RAM Internal ROM/RAM Size The NX2LP-Flex has 1 kBytes ROM and 15 kBytes of internal program/data RAM, where PSEN#/RD# signals are internally ORed to allow the 8051 to access it as both program and data memory. No USB control registers appear in this space. Internal Code Memory This mode implements the internal block of RAM (starting at 0x0500) as combined code and data memory, as shown in Figure 6, below.

For high-speed endpoint configuration options, see Figure 8. Setup Data Buffer A separate 8-byte buffer at 0xE6B8-0xE6BF holds the setup data from a CONTROL transfer. Endpoint Configurations (High-speed Mode) Endpoints 0 and 1 are the same for every configuration. Endpoint 0 is the only CONTROL endpoint, and endpoint 1 can be either BULK or INTERRUPT. The endpoint buffers can be configured in any 1 of the 12 configurations shown in the vertical columns. When operating in full-speed BULK mode, only the first 64 bytes of each buffer are used. For example, in high-speed the max packet size is 512 bytes, but in full-speed it is 64 bytes. Even though a buffer is configured to be a 512 byte buffer, in full-speed only the first 64 bytes are used. The unused endpoint buffer space is not available for other operations. An example endpoint configuration would be: EP2-1024 double buffered; (column 8 in Figure 8). EP6-512 quad buffered Figure 8.

In operation, some of the eight RAM blocks fill or empty from the SIE, while the others are connected to the I/O transfer logic. The transfer logic takes two forms, the GPIF for internally generated control signals, or the slave FIFO interface for externally controlled transfers. Master/Slave Control Signals The NX2LP-Flex endpoint FIFOS are implemented as eight physically distinct 256x16 RAM blocks. The 8051/SIE can switch any of the RAM blocks between two domains, the USB (SIE) domain and the 8051-I/O Unit domain. This switching is done virtually instantaneously, giving essentially zero transfer time between `USB FIFOS' and `Slave FIFOS.' Since they are physically the same memory, no bytes are actually transferred between buffers. At any given time, some RAM blocks are filling/emptying with USB data under SIE control, while other RAM blocks are available to the 8051 and/or the I/O control unit. The RAM blocks operate as single-port in the USB domain, and dual-port in the 8051-I/O domain. The blocks can be configured as single, double, triple, or quad buffered as previously shown. The I/O control unit implements either an internal-master (M for master) or external-master (S for Slave) interface. In Master (M) mode, the GPIF internally controls FIFOADR[1:0] to select a FIFO. The two RDY pins can be used as flag inputs from an external FIFO or other logic if desired. The GPIF can be run from an internally derived clock 64 0 0 0 0 0 0 0 64 512 bulk[4] 512 bulk[4] 512 bulk out (2x) 512 bulk out (2x) 512 bulk in (2x) 512 bulk in (2x) 1 64 64 int 64 int 512 int out (2x) 512 bulk out (2x) 512 int in (2x) 512 bulk in (2x) 2 64 64 int 64 int 512 iso out (2x) 512 bulk out (2x) 512 iso in (2x) 512 bulk in (2x) 3 (IFCLK), at a rate that transfers data up to 96 Megabytes/s (48-MHz IFCLK with 16-bit interface). In Slave (S) mode, the NX2LP-Flex accepts an internally derived clock (IFCLK, max. frequency 48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals from external logic. Each endpoint can individually be selected for byte or word operation by an internal configuration bit, and a Slave FIFO Output Enable signal SLOE enables data of the selected width. External logic must ensure that the output enable signal is inactive when writing data to a slave FIFO. The slave interface must operate asynchronously, where the SLRD and SLWR signals act directly as strobes, rather than a clock qualifier as in a synchronous mode. The signals SLRD, SLWR, SLOE and PKTEND are gated by the signal SLCS#. GPIF and FIFO Clock Rates An 8051 register bit selects one of two frequencies for the internally supplied interface clock: 30 MHz and 48 MHz. A bit within the IFCONFIG register will invert the IFCLK signal. The default NAND firmware image implements a 48-MHz internally supplied interface clock. The NAND boot logic uses the same configuration to implement 100-ns timing on the NAND bus to support proper detection of all NAND Flash types. GPIF The GPIF is a flexible 8- or 16-bit parallel interface driven by a user-programmable finite state machine. It allows the NX2LP-Flex to perform local bus mastering, and can implement a wide variety of protocols such as 8-bit NAND interface, printer parallel port, and Utopia. The default NAND firmware and boot logic utilizes GPIF functionality to interface with NAND Flash. The GPIF on the NX2LP-Flex features three programmable control outputs (CTL) and two general-purpose ready inputs (RDY). The GPIF data bus width can be 8 or 16 bits. Because Note 4. Even though these buffers are 64 bytes, they are reported as 512 for USB 2.0 compliance. The user must never transfer packets larger than 64 bytes to EP1. Document #: 001-04247 Rev. *D Page 10 of 33 [+] Feedback CY7C68033/CY7C68034 the default NAND firmware image implements an 8-bit data bus and up to 8 chip enable pins on the GPIF ports, it is recommended that designs based upon the default firmware image use an 8-bit data bus as well. Each GPIF vector defines the state of the control outputs, and determines what state a ready input (or multiple inputs) must be before proceeding. The GPIF vector can be programmed to advance a FIFO to the next data value, advance an address, etc. A sequence of the GPIF vectors make up a single waveform that will be executed to perform the desired data move between the NX2LP-Flex and the external device. Three Control OUT Signals The NX2LP-Flex exposes three control signals, CTL[2:0]. CTLx waveform edges can be programmed to make transitions as fast as once per clock (20.8 ns using a 48-MHz clock). Two Ready IN Signals The 8051 programs the GPIF unit to test the RDY pins for GPIF branching. The 56-pin package brings out two signals, RDY[1:0]. Long Transfer Mode In GPIF Master mode, the 8051 appropriately sets GPIF transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or GPIFTCB0) for unattended transfers of up to 232 transactions. The GPIF automatically throttles data flow to prevent under- or over-flow until the full number of requested transactions complete. The GPIF decrements the value in these registers to represent the current status of the transaction. ECC Generation[5] The NX2LP-Flex can calculate ECCs (Error-Correcting Codes) on data that passes across its GPIF or Slave FIFO interfaces. There are two ECC configurations: * Two ECCs, each calculated over 256 bytes (SmartMedia Standard) * One ECC calculated over 512 bytes. The two ECC configurations described below are selected by the ECCM bit. The ECC can correct any one-bit error or detect any two-bit error. ECCM = 0 Two 3-byte ECCs, each calculated over a 256-byte block of data. This configuration conforms to the SmartMedia Standard and is used by both the NAND boot logic and default NAND firmware image. When any value is written to ECCRESET and data is then passed across the GPIF or Slave FIFO interface, the ECC for the first 256 bytes of data will be calculated and stored in ECC1. The ECC for the next 256 bytes of data will be stored in ECC2. After the second ECC is calculated, the values in the ECCx registers will not change until ECCRESET is written again, even if more data is subsequently passed across the interface. ECCM = 1 One 3-byte ECC calculated over a 512-byte block of data. When any value is written to ECCRESET and data is then passed across the GPIF or Slave FIFO interface, the ECC for the first 512 bytes of data will be calculated and stored in ECC1; ECC2 is unused. After the ECC is calculated, the value in ECC1 will not change until ECCRESET is written again, even if more data is subsequently passed across the interface Autopointer Access NX2LP-Flex provides two identical autopointers. They are similar to the internal 8051 data pointers, but with an additional feature: they can optionally increment after every memory access. Also, the autopointers can point to any NX2LP-Flex register or endpoint buffer space. I2C Controller NX2LP has one I2C port that the 8051, once running uses to control external I2C devices. The I2C port operates in master mode only. The I2C post is disabled at startup and only available for use after the initial NAND access. I2C Port Pins The I2C pins SCL and SDA must have external 2.2-k pull-up resistors even if no EEPROM is connected to the NX2LP. I2C Interface General-Purpose Access The 8051 can control peripherals connected to the I2C bus using the I2CTL and I2DATA registers. NX2LP provides I2C master control only and is never an I2C slave. Note 5. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation. Document #: 001-04247 Rev. *D Page 11 of 33 [+] Feedback CY7C68033/CY7C68034 Pin Assignments Figure 9 and Figure 10 identify all signals for the 56-pin NX2LP-Flex package. Three modes of operation are available for the NX2LP-Flex: Port mode, GPIF Master mode, and Slave FIFO mode. These modes define the signals on the right edge of each column in Figure 9. The right-most column details the signal functionality from the default NAND firmware image, which actually utilizes GPIF Master mode. The signals on the left edge of the `Port' column are common to all modes of the NX2LP-Flex. The 8051 selects the interface mode using the IFCONFIG[1:0] register bits. Port mode is the power-on default configuration. Figure 10 details the pinout of the 56-pin package and lists pin names for all modes of operation.

It shows a single read followed by a burst read. * At t = 0 the FIFO address is stable and the SLCS signal is asserted. * At t = 1, SLOE is asserted. This results in the data bus being driven. The data that is driven on to the bus is previous data, it data that was in the FIFO from a prior read cycle. * At t = 2, SLRD is asserted. The SLRD must meet the minimum active pulse of tRDpwl and minimum de-active pulse width of tRDpwh. If SLCS is used then, SLCS must be in asserted with SLRD or before SLRD is asserted (that is the SLCS and SLRD signals must both be asserted to start a valid read condition). Sequence Diagram of a Single and Burst Asynchronous Write * The data that will be driven, after asserting SLRD, is the updated data from the FIFO. This data is valid after a propagation delay of tXFD from the activating edge of SLRD. In Figure 17, data N is the first valid data read from the FIFO. For data to appear on the data bus during the read cycle (that is SLRD is asserted), SLOE MUST be in an asserted state. SLRD and SLOE can also be tied together. The same sequence of events is also shown for a burst read marked with T = 0 through 5. Note: In burst read mode, during SLOE is assertion, the data bus is in a driven state and outputs the previous data. Once SLRD is asserted, the data from the FIFO is driven on the data bus (SLOE must also be asserted) and then the FIFO pointer is incremented. Figure 19.

The diagram shows a single write followed by a burst write of 3 bytes and committing the 4-byte-short packet using PKTEND. * At t = 0 the FIFO address is applied, insuring that it meets the setup time of tSFA. If SLCS is used, it must also be asserted (SLCS may be tied low in some applications). * At t = 1 SLWR is asserted. SLWR must meet the minimum active pulse of tWRpwl and minimum de-active pulse width of tWRpwh. If the SLCS is used, it must be in asserted with SLWR or before SLWR is asserted. * At t = 2, data must be present on the bus tSFD before the deasserting edge of SLWR. * At t = 3, deasserting SLWR will cause the data to be written from the data bus to the FIFO and then increments the FIFO pointer. The FIFO flag is also updated after tXFLG from the deasserting edge of SLWR. The same sequence of events are shown for a burst write and is indicated by the timing marks of T = 0 through 5. Note: In the burst write mode, once SLWR is deasserted, the data is written to the FIFO and then the FIFO pointer is incremented to the next byte in the FIFO. The FIFO pointer is post incremented. In Figure 19 once the four bytes are written to the FIFO and SLWR is deasserted, the short 4-byte packet can be committed to the host using the PKTEND. The external device should be designed to not assert SLWR and the PKTEND signal at the same time. It should be designed to assert the PKTEND after SLWR is deasserted and met the minimum de-asserted pulse width. The FIFOADDR lines are to be held constant during the PKTEND assertion.

Do not allow the plane to be split under these traces. * No vias should be placed on the DPLUS or DMINUS trace routing unless absolutely necessary. * Isolate the DPLUS and DMINUS traces from all other signal traces as much as possible. heat transfer area below the package to provide a good thermal bond to the circuit board. A Copper (Cu) fill is to be designed into the PCB as a thermal pad under the package. Heat is transferred from the NX2LP-Flex to the PCB through the device's metal paddle on the bottom side of the package. It is then conducted from the PCB's thermal pad to the inner ground plane by a 5 x 5 array of vias. A via is a plated through hole in the PCB with a finished diameter of 13 mil. The QFN's metal die paddle must be soldered to the PCB's thermal pad. Solder mask is placed on the board top side over each via to resist solder flow into the via. The mask on the top side also minimizes outgassing during the solder reflow process. For further information on this package design please refer to the application note Surface Mount Assembly of AMKOR's MicroLeadFrame (MLF) Technology. This application note can be downloaded from AMKOR's website from the following URL: http://www.amkor.com/products/notes_papers/ MLF_AppNote_0902.pdf. The application note provides detailed information on board mounting guidelines, soldering flow, rework process, etc. Figure 21 below displays a cross-sectional area underneath the package. The cross section is of only one via. The solder paste template needs to be designed to allow at least 50% solder coverage. The thickness of the solder paste template should be 5 mil. It is recommended that `No Clean' type 3 solder paste is used for mounting the part. Nitrogen purge is recommended during reflow.
