Description

The M24M01 is a 1 Mb I2C-compatible EEPROM (Electrically Erasable PROgrammable

Memory) organized as 128 K × 8 bits.

The M24M01-R can operate with a supply voltage from 1.8 V to 5.5 V, and the M24M01-DF

can operate with a supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of

–40°C / +85°C.

The M24M01-D offers an additional page, named the Identification Page (256 bytes). The

Identification Page can be used to store sensitive application parameters which can be

(later) permanently locked in Read-only mode.
