DESCRIPTION

These I

C-compatible electrically erasable pro-

grammable memory (EEPROM) devices are orga-

nized as 32Kx8 bits, and operate down to 2.5 V

(for the M24256-AW), and down to 1.8 V (for the

M24256-AR).

The M24256-A is available in Plastic Dual-in-Line,

Plastic Small Outline and Thin Shrink Small Out-

line packages.
