Description
1 Description
M93Cx6-DRE
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-DRE devices operate within a voltage supply range from 1.8 V to 5.5 V
The M93Cx6-DRE devices are guaranteed over the -40 °C/+105 °C temperature range and
are compliant with the level of reliability defined by the AEC-Q100 grade 2.
