C-compatible electrically erasable pro-
grammable memory (EEPROM) devices are orga-
nized as 32Kx8 bits (M24256) and 16Kx8 bits
(M24128), and operate down to 2.5 V (for the -W
version of each device).
The M24256B, M24128B and M24256A are also
available, and offer the extra functionality of the
chip enable inputs. Please see the separate data
