The M24C64 is a 64-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) organized as 8K × 8 bits. Over an ambient temperature range of -40 °C / +85 °C, 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 ( the M24C64-F can also operate down to 1.6 V, under some restricting conditions). The M24C64-D offers an additional page, named the identification page (32 byte). The identification page can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

The M24M01E-F is a 1-Mbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 128 K × 8 bits. It can operate with a supply voltage from 1.6 V to 5.5 V with a clock frequency up to 1 MHz, over an ambient temperature range of -40 °C to +85 °C. The device offers three 8-bit registers, namely: the device type identifier (DTI) register, the configurable device address (CDA), and the software write protection (SWP) register. The device offers an additional 256-byte page, called the identification page. This page can be used to store sensitive application parameters, which can later be permanently locked in read-only mode. The M24M01E-F is available in the standard 8-pin TSSOP8, SO8N, UFDFPN8, and in the 5-ball wafer level chip scale packaging (WLCSP) with the WC pin. On demand, the EEPROM can be delivered with a preprogrammed and locked device address.
