Description
The M93C46 (1 Kbit), M93C56 (2 Kbit), M93C66 (4 Kbit), M93C76 (8 Kbit) and M93C86
(16 Kbit) are Electrically Erasable PROgrammable Memory (EEPROM) devices accessed
through the MICROWIRE bus protocol. The memory array can be configured either in bytes
(x8b) or in words (x16b).
The M93Cx6 devices operate within a voltage supply range from 4.5 V to 5.5 V, and the
M93Cx6-W devices operate within a voltage supply range from 2.5 V to 5.5 V.
The M93Cx6 devices are guaranteed over the -40°C/+125°C temperature range and are
compliant with the Automotive standard AEC-Q100 Grade 1.
