Description

The V29C51000T/V29C51000B is a high speed 65,536 x 8 bit CMOS flash memory. Programming or erasing the device is done with a single 5 Volt power supply. The device has separate chip enable CE, program enable WE, and output enable OE controls to eliminate bus contention.

The V29C51000T/V29C51000B offers a combination of features: Boot Block with Sector Erase Mode. The end of program/erase cycle is detected by DATA Polling of I/O7 or by the Toggle Bit I/O6.

The V29C51000T/V29C51000B 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 either the top (V29C51000T) or bottom (V29C51000B) sector. All inputs and outputs are CMOS and TTL compatible.

The V29C51000T/V29C51000B is ideal for applications that require updatable code and data storage.
