Overview
The M24C64-WMN6T is a 64-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) produced by STMicroelectronics. This device is organized as 8K × 8 bits and operates over an ambient temperature range of -40 °C to +85 °C. The M24C64-W model, specifically, can operate with a supply voltage from 2.5 V to 5.5 V. The EEPROM is designed for various applications requiring non-volatile memory and features enhanced ESD/latch-up protection, high data retention, and multiple write cycles.
