DESCRIPTION The M29W004 is a non-volatile memory that may be erased electrically at the block or chip level a nd programmed in-system on a Byte-by-Byte basis using only a single 2.7V to 3.6V VCC supply. For Program and Erase operations t he necessary hi gh voltages are generated internally. The device can also be programmed in standard programmers. The array matrix organisation al lows each block to be erased and reprogrammed without affecting other blocks. Blocks can be protected against programing and erase on programming equipment, and temporarily unprotect ed to make changes in the application . Each block can be programmed and erased over 100,000 cycles.
