AT24C64D-SSHM-T Microchip 64Kbit EEPROM Memory IC
The AT24C64D-SSHM-T is a 64-Kbit serial EEPROM manufactured by Microchip Technology (formerly Atmel), organized as 8,192 words of 8 bits each and accessed through a standard 2-wire I2C-compatible serial interface. Designed for industrial, commercial, and consumer applications requiring reliable non-volatile storage, this device supports cascaded operation allowing up to eight units to share a single bus through hardware address pins (E0, E1, E2), while an additional 128-bit factory-programmed serial number and a user-lockable page provide enhanced security and device identification capabilities for embedded systems, IoT nodes, and communication equipment.
Operating across a wide supply voltage range of 1.7V to 5.5V, the device supports clock frequencies up to 1MHz at 2.5V-5.5V and 400kHz at 1.7V-2.5V, ensuring compatibility with legacy 5V systems and modern low-voltage microcontrollers alike. Its CMOS design delivers ultra-low power consumption with typical read current of 0.2mA and write current of 0.6mA at 400kHz, while standby current remains approximately 6uA, making it ideal for battery-powered portable devices and energy-harvesting applications. The industrial-grade temperature rating of -40C to +85C guarantees consistent performance in harsh environmental conditions.
