The AT24C64D-SSHM-T is a 64-Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology, housed in a compact SOIC-8 package. This device offers a flexible operating voltage range from 1.7V to 5.5V, making it suitable for both low-power and standard 5V systems. It supports a maximum clock frequency of 1 MHz for the I²C interface, enabling fast data transfer. The memory is organized as 64K bits with a 32-byte page write capability, enhancing write efficiency. It features a whole-array hardware write protection scheme, though the write protect function is disabled by default. With an endurance of 1,000,000 write cycles, this EEPROM is designed for reliable long-term data storage in applications requiring frequent parameter updates, such as industrial control, consumer electronics, and communication devices. Its standard SOIC-8 footprint ensures easy integration into existing PCB designs.
