29F400T
29F400T is M29F400T manufactured by STMicroelectronics.
DESCRIPTION
The M29F400 is a non-volatile memory that may be erased electrically at the block or chip level and programmed in-system on a Byte-by-Byte or Wordby-Word basis using only a single 5V V CC 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 pro November 1999
