Microchip Technology's 25CS640 is a 64-kilobit serial EEPROM featuring an 8KX8 organization, operating via the SPI bus. This CMOS device supports a clock frequency up to 20 MHz and operates across a -40°C to +150°C temperature range. With a data retention exceeding 200 years and an endurance of 400,000 write cycles, it offers robust, non-volatile data storage. The 25CS640 is housed in a space-saving, surface-mount PDSO8 (TSSOP) package with a 0.65mm terminal pitch. It is suitable for applications requiring reliable data logging and configuration storage, including industrial control systems, consumer electronics, and automotive subsystems. The device supports hardware write protection and operates from a 2.5V to 5.5V supply.
