Product overview
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-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.
