Microchip Technology's 25C640T-I-ST is a 64-kilobit (8K x 8) serial EEPROM device utilizing CMOS technology. This component offers robust data retention exceeding 200 years and features 4KV ESD protection. Its high endurance rating of 1 million write cycles ensures reliability for demanding applications. Operating from a 4.5V to 5.5V supply range, it supports SPI serial bus communication at clock frequencies up to 3.0 MHz. The 25C640 series is suitable for industrial and automotive environments with an operating temperature range of -40°C to +85°C. Housed in a compact 8-lead PDSO (TSSOP) package with a 0.65mm terminal pitch, this device is designed for surface mounting. It finds application in systems requiring non-volatile data storage, such as configuration settings and calibration data across various industrial control and consumer electronics.
