Description

The M93C86, M93C76, M93C66, M93C56 and M93C46 are electrically erasable

programmable memory (EEPROM) devices. They are accessed through a Serial Data input

(D) and Serial Data output (Q) using the MICROWIRE bus protocol.

Logic diagram

The memory array organization may be divided into either bytes (x8) or words (x16) which

may be selected by a signal applied on Organization Select (ORG). The bit, byte and word

sizes of the memories are as shown in Table 3.
