STMicroelectronics M24C32-U
The M24C32-U is a 32-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 4 K × 8 bits. It can operate with a supply voltage of 1.7 V to 5.5 V, over an ambient temperature range from -40 °C to +85 °C. The device offers an additional page, named the identification page (32 bytes).FEATURES
