Microchip Technology's 25CS640T-E-Q4B is a 64Kb serial CMOS electrically erasable programmable read-only memory (EEPROM) with an 8KX8 organization. This device operates over a wide supply voltage range of 1.8V to 5.5V and supports SPI serial bus communication up to 20 MHz. It offers 400,000 endurance cycles and a data retention of 200 years. The EEPROM is housed in a compact 8-terminal HWSON package (JESD-30 Code: R-PDSO-N8) with a 0.5mm pitch, suitable for surface-mount applications. Key features include hardware write protection and a low standby current of 5µA. This component is widely utilized in industrial, automotive, and consumer electronics for data storage and configuration.
