The V29C51400T/V29C51400B is a high speed
262,144 x 16 bit or 524,288 x 8-bit CMOS flash
memory. Writing or erasing the device is done with
a single 5 Volt power supply. The device has
separate chip enable CE, write enable WE, and
output enable OE controls to eliminate bus
contention.
The V29C51400T/V29C51400B offers a combi-
nation of: Boot Block with Sector Erase/Write
Mode. The end of write/erase cycle is detected by
DATA Polling of I/O
7
or by the Toggle Bit I/O
6
.
The V29C51400T/V29C51400B features a
sector erase operation which allows each sector to
be erased and reprogrammed without affecting
data stored in other sectors. The device also
supports full chip erase.
Boot block architecture enables the device to
boot from a protected sector located either at the
top (V29C51400T) or the bottom (V29C51400B).
All inputs and outputs are CMOS and TTL
compatible.
The V29C51400T/V29C51400B is ideal for
applications that require updatable code and data
storage.
