FEATURES
GENERAL DESCRIPTION
This device is designed to use a 5.0 Volt power supply to perform in-system programming, 12.0 Volt V
supply for program and erase operation is not required. The device can be programmed in standard EPROM
programmers as well.
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.
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.
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.
device is packaged in a 32-pin DIP and PLCC with access time of 55, 70 and 90 ns.
