DESCRIPTION

These I C-compatible electrically erasable pro-

grammable memory (EEPROM) devices are orga-

nized as 32Kx8 bits (M24256-B) and 16Kx8 bits

(M24128-B).

Figure 1. Logic Diagram

These memory devices are compatible with the

I C extended memory standard. This is a two wire

serial interface that uses a bi-directional data bus

and serial clock. The memory carries a built-in 4-

bit unique Device Type Identifier code (1010) in

accordance with the I C bus definition.
