M29W800B
M29W800B is 8 Mbit 1Mb x8 or 512Kb x16 / Boot Block Low Voltage Single Supply Flash Memory manufactured by STMicroelectronics.
DESCRIPTION
The M29W800 is a non-volatile memory that may be erased electrically at the block or chip level and programmed in-system on a Byte-by-Byteor Wordby-Word basis using only a single 2.7V to 3.6V VCC supply. For Program and Erase operations the necessary high voltages are generated internally. The device can also be programmed in standard programmers. The array matrix organisation allows each block to be erased and reprogrammed without affecting other blocks. Blocks can be protected against programing and erase on programming equipment,
