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 V29C51002T/V29C51002B offers a bination of: Boot Block with Sector Erase/Write Mode. The end of write/erase cycle is detected by DATA Polling of I/O7 or by the Toggle Bit I/O6. The V29C51002T/V29C51002B 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 (V29C51002T) or the bottom (V29C51002B). All inputs and outputs are CMOS and TTL patible. The V29C51002T/V29C51002B is ideal for applications that require updatable code and data storage. s Device Usage Chart Operating Temperature Range 0°C to 70°C Package Outline P - T - J - Access Time (ns) 55 - 90 - Temperature Mark Blank V29C51002T/V29C51002B Rev. 2.1 October 2000 MOSEL VITELIC V29C51002T/V29C51002B 51 002 - OPERATING...
