Description

The M24C32 is a 32-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable

Memory) organized as 4 K × 8 bits.

The M24C32-W can operate with a supply voltage from 2.5 V to 5.5 V, the M24C32-R can

operate with a supply voltage from 1.8 V to 5.5 V, and the M24C32-F and M24C32-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; while the M24C32-X can operate with a supply voltage from 1.6 V to 5.5 V

over an ambient temperature range of -20 °C / +85 °C.

The M24C32-D offers an additional page, named the Identification Page (32 bytes). The

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

(later) permanently locked in Read-only mode.
