This datasheet describes the STMicroelectronics M24512 series of 512 Kbit (64 Kbytes) EEPROM devices. The devices are available in four versions: M24512-W, M24512-R, M24512-DR and M24512-DF. The M24512 series EEPROM devices are compatible with all I2C bus modes, operate with a supply voltage of 1.7V to 5.5V and have a temperature range of -40°C to +85°C. The M24512 series EEPROM devices offer random read and sequential read modes, write protection and enhanced ESD/Latch-Up protection.
This document is a datasheet for the STMicroelectronics M24512 series of 512-Kbit (64 Kbytes) serial I2C bus EEPROMs. The series includes variants M24512-W, M24512-R, M24512-DR, and M24512-DF, which differ primarily by their operating supply voltage ranges. The devices support I2C bus modes up to 1 MHz and feature a page size of 128 bytes.
