  • 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-W devices operate within a voltage supply range from 2.5 V to 5.5 V and the M93Cx6-R devices operate within a voltage supply range from 1.8 V to 5.5 V. All these devices operate with a clock frequency of 2 MHz (or less), over an ambient temperature range of - 40 °C / + 85 °C.

    Key Features

    • Industry standard MICROWIRE™ bus
    • Single supply voltage:
      • 2.5 V to 5.5 V for M93Cx6-W
      • 1.8 V to 5.5 V for M93Cx6-R
    • Dual organization: by word (x16) or byte (x8)
    • Programming instructions that work on: byte, word or entire memory
    • Self-timed programming cycle with auto-erase: 5 ms
    • READY/BUSYsignal during programming
    • 2 MHz clock rate
    • Sequential read operation
    • Enhanced ESD/latch-up behavior
    • More than 4 million write cycles
    • More than 200-year data retention
    • Packages
      • SO8, TSSOP8, UFDFPN8 packages: ECOPACK2®)
      • PDIP8 package: ECOPACK1®
