The Microchip Technology 25CS640T-H-SN is a 64-kilobit serial CMOS EEPROM. With an 8K x 8 memory organization, this device supports SPI serial bus communication up to 20 MHz. It features a wide operating voltage range from 2.5V to 5.5V and operates reliably across an industrial temperature range of -40°C to +150°C. The 25CS640 series offers 400,000 erase/write endurance cycles and a data retention of over 200 years. Packaging is in an 8-lead PDSO (SOP) package with a 1.27mm pitch. Applications include industrial automation, automotive systems, and consumer electronics requiring persistent data storage. Hardware write protection is implemented for enhanced data integrity.
