STMicroelectronics M24512E-FDW6TP, 512kB EEPROM Memory Chip, 450ns 8-Pin TSSOP8 I2C

The STMicroelectronics M24512E-F is a 512-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 64 K x 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. The device offers three 8-bit registers, namely the device type identifier (DTI) register, the configurable device address (CDA) register, and the software write protection (SWP) register.
