Description

The V29LC51002 is a high speed 262,144 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 V29LC51002 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.
