M24C32-W M24C32-R M24C32-F M24C32-X M24C32-DF
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.
