1 Description
The M24C01(C02) is a 1(2)-Kbit I
2
C-compatible EEPROM (Electrically Erasable
PROgrammable Memory) organized as 128 (256) × 8
bits.
The M24C01/02-W can be accessed with a supply voltage from 2.5 V to 5.5 V, the
M24C01/02-R can be accessed with a supply voltage from 1.8
V to 5.5 V, and the
M24C02-F can be accessed either with a supply voltage from 1.7 V to 5.5
V (over the full
temperature range) or with an extended supply voltage from 1.6
V to 1.7 V if the
temperature is reduced to 0
°C/ 85 °C. All these devices operate with a clock frequency of
400 kHz.
