M29F400T 4 Mbit 512Kb x8 or 256Kb x16 / Boot Block Single Supply Flash Memory

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 o.

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 proNovember 1999 44 1 TSOP48 (N) 12 x 20 mm SO44 (M) Figure 1. Logic Diagram VCC 18 A0-A17 W E G RP M29F400T M29F400B 15 DQ0-DQ14 DQ15A
