  • 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.

    Key Features

    • Industry standard MICROWIRE™ bus
    • Memory array: 1 Kb, 2 Kb, 4 Kb, 8 Kb or 16 Kb
    • Dual organization: by word (x16) or byte (x8)
