M24C64-R

64 Kbit serial I2C bus EEPROM
  • active Active

The M24C64 is a 64-Kbit I2C-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.

The M24C64-D offers an additional page, named the Identification Page (32 bytes). The Identification Page can be (later) permanently locked in Read-only mode.
