Description

M24512-W M24512-R M24512-DF

The M24512 is a 512-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable

Memory) organized as 64 K × 8 bits.

The M24512-W can operate with a supply voltage from 2.5 V to 5.5 V, the M24512-R can

operate with a supply voltage from 1.8 V to 5.5 V and the M24512-DF can operate with a

supply voltage from 1.7 V to 5.5 V. All these devices operate with a clock frequency of 1

MHz (or less) over an ambient temperature range of -40 °C / +85 °C.

The M24512-D offers an additional page, named the Identification Page (128 byte). The

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

(later) permanently locked in Read-only mode.
