Microchip Technology's 25CS640T-H-Q4B is a 64-kilobit, 8K x 8 serial CMOS EEPROM. This component operates via the SPI bus, supporting clock frequencies up to 20 MHz. It offers robust data retention of 200 years and an endurance rating of 400,000 write cycles. The device features hardware write protection and is housed in a compact 8-pin HWSON package (JESD-30 Code R-PDSO-N8) with a 0.5mm terminal pitch. Operating across a temperature range of -40°C to +150°C, it is suitable for applications requiring reliable non-volatile data storage in industrial and automotive environments. The 25CS640 series is designed for general-purpose memory needs in embedded systems.
