1 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).
(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.
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.
