1 Description
The M24C64 is a 64-Kbit I
2
C-compatible EEPROM (Electrically Erasable PROgrammable
Memory) organized as 8 K × 8 bits.
The M24C64-W can operate with a supply voltage from 2.5 V to 5.5 V, the M24C64-R can
operate with a supply voltage from 1.8 V to 5.5 V, and the M24C64-F and M24C64-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.

operate with a supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of
-40 °C / +85 °C.
The M24C64-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.
