GENERAL DESCRIPTION
The PM29F002 is a 2 Megabit, 5.0 Volt-only Flash Memory organized as 262,144 bytes of 8 bits each. This device is designed to use a 5.0 Volt power supply to perform in-system programming, 12.0 Volt VPP power supply for program and erase operation is not required. The device can be programmed in standard EPROM programmers as well. The 2 Megabit memory array is divided into five blocks of one 16 Kbytes, two 8 Kbytes, one 96 Kbytes, and one 128 Kbytes for BIOS and parameters storage. The five blocks allow users to flexibly make chip erase or block erase operation flexible. The block erase feature allows a particular block to be erased and reprogrammed without affecting the data in other blocks. After the device performed chip erase or block erase operation, it can be reprogrammed on a byte-by-byte basis. The device has a standard microprocessor interface as well as JEDEC single-power-supply Flash compatible pin-out and command set. The program operation of PM29F002 is executed by issuing the program command code into command register. The internal control logic automatically handles the programming voltage ramp-up and timing. The erase operation of PM29F002 is executed by issuing the chip erase or block erase command code into command register. The internal control logic automatically handles the erase voltage ramp-up and timing. The preprogramming on the array which has not been programmed is not required before the erase operation. The device also features Data# Polling and Toggle Bit function, the end of program or erase operation can be detected by Data# Polling of I/O7 or Toggle Bit of I/O6. The device has an optional 16 Kbytes top or bottom boot block with a software lockout feature for data security. The boot block can be used to store user secure code. When the lockout feature is enabled, the boot block is permanently protected from being reprogrammed. The PM29F002 is manufactured on PMC's 0.30 m advanced nonvolatile technology, P-FLASHTM. The device is packaged in a 32-pin DIP and PLCC with access time of 55, 70 and 90 ns.

TYPE INPUT
DESCRIPTION Address Inputs: For memory addresses and command register. Addresses are internally latched during a write cycle. Chip Enable: CE# low activates the device's internal circuitries for device operation. CE# high deselects the device and switches into standby mode to reduce the power consumption. Please refer to DC characteristics table. Write Enable: Activate the device for write operation. WE# is active low. Output Enable: Control the device's data buffers during a read cycle. OE# is active low. Data Inputs/Outputs: Inputs array data during program operation, when CE# and WE# are active. Data is internally latched during the write and program cycles. When CE# and OE# are active, the output sends array data, manufacturer code or device code. The data pins float to tri-state when the chip is deselected or the outputs are disabled.

DEVICE OPERATION
READ OPERATION The access of PM29F002 is similar as that of EPROM. To obtain data at the outputs, three control functions must be satisfied: * CE# is the chip enable and should be pulled low ( VIL ). * OE# is the output enable and should be pulled low ( VIL). * WE# is the write enable and should remains high ( VIH ). BOOT BLOCK LOCKOUT The device has a software lockout feature to prevent the data in the boot block from being erased or reprogrammed. The boot block can be located at the top or bottom of the address location. The block size is 16 Kbytes. Once the lockout feature is enable, the boot block can not be erased or reprogrammed. Data in the main memory block can still be updated through the regular programming method. The boot block lockout feature can be turned on by issuing a six-bus-cycle command sequence. Please refer to Table 4 and Chart 4.
Programmable Microelectronics Corp.
BOOT BLOCK LOCKOUT DETECTION The state of the Boot Block lockout can be detected by software product identification entry. After entry, selects Boot Block address with A0 = "0" and A1 = "1" and then read I/O0. A data of "0" means the lockout feature is disabled and the Boot Block can be erased or programmed. A data of "1" means the lockout feature is enabled and the Boot Block is protected. Product identification exit must be executed before the device returns to read mode. PRODUCT IDENTIFICATION The product identification mode can be used to identify the device and the manufacturer by hardware or software operation. The hardware operation mode is activated by applying a 12.0 Volt on A9 pin, typically used by an external programmer to select the right programming algorithm for the device. For detail, please see Bus Operation Modes in Table 3. The software operation mode is activated by three-bus-cycle command. Please see Software Command Definition in Table 4.

DEVICE OPERATION (CONTINUED)
PM29F002
BYTE PROGRAMMING The programming is a four-bus-cycle operation and the data is programmed into the device (to a logical "0") on a byte-by-byte basis. Please see Software Command Definition in Table 4. A program operation is activated by writing the three-byte command sequence followed by one byte of data into the device. The address are latched on the falling edge of WE# or CE# whichever occurs later, and the data is latched on the rising edge of WE# or CE#, whichever occurs first. The internal control logic automatically handles the internal programming voltages and timing. A data "0" can not be programmed back to a "1". Only erase operation can convert "0"s to "1"s. The Data# Polling of I/O7 or Toggle Bit of I/O6 can be used to detect when the programming operation is completed. CHIP ERASE The entire memory array can be erased through a chip erase operation. Pre-programs the device is not required prior to chip erase operation. Chip erase starts after a six-bus-cycle chip erase command sequence. All commands will be ignored once the chip erase operation has started. The device will return back to read mode after the completion of chip erase. When the boot block lockout feature is enabled, the boot block will not be erased during a chip erase operation. Only the parameter blocks and the main blocks will be erased. BLOCK ERASE The memory array is organized into five blocks: one 16 Kbytes boot block, two 8 Kbytes parameter blocks, one 96 Kbytes and one 128 Kbytes main blocks. A block erase operation allows to erase any individual block. Pre-programs the block is not required prior to block erase operation. If the boot block lockout feature is enable, the block erase command attempts to erase the boot block will be ignored. The block erase command is similar to chip erase command except for the last bus cycle command where the block addresses are used to select the block for erasure and the input data to the I/Os is 30h. Each block erase operation erases one block. Block erase and chip erase are both internally controlled and timed.
I/O7 DATA# POLLING The PM29F002 provides Data# Polling feature to indicate the process or the completion of a program or erase cycle. During a program cycle, an attempt to read the device will result in the complement of the last loaded data on I/O7. Once the program cycle is completed, the true data of the last loaded data is valid on all outputs. During a block or chip erase operation, an attempt to read the device will result a "0" on I/O7. After the erase cycle is completed, an attempt to read the device will result a "1" on I/O7. I/O6 TOGGLE BIT The PM29F002 also provides Toggle Bit feature as a method to detect the process or the end of a program or erase cycle. During a program or erase operation, an attempt to read data from the device will result in I/O6 toggling between "1" and "0". When the program or erase operation is complete, I/O6 will stop toggling and valid data will be read. Toggle bit may be accessed at any time during a program or erase cycle. HARDWARE DATA PROTECTION Hardware data protection protects the device from unintentional erase or program operation. It is performed in the following ways: (a) VCC sense: if VCC is below 3.8 V (typical), the program function is inhibited. (b) Write inhibit: holding any of the signal OE# low, CE# high or WE# high inhibits a write cycle. (c) Noise filter: pulses of less than 20 ns (typical) on the WE# or CE# inputs will not initiate a write cycle.
