Microchip Technology 25CS640 is an 8K x 8 bit serial EEPROM utilizing CMOS technology. This serial memory component supports the SPI bus interface, enabling high-speed synchronous operation up to 20 MHz. With a generous data retention of 200 years and an endurance rating of 400,000 write cycles, it is engineered for demanding applications. The device operates across a wide temperature range of -40°C to +85°C and accommodates supply voltages from 1.7V to 5.5V, with a nominal 2.5V operation. Featuring hardware write protection and a 3-state output, the 25CS640 is suitable for use in industrial, automotive, and consumer electronics sectors where reliable non-volatile data storage is critical. The component is housed in an 8-pin HWSON package with a terminal pitch of 0.500 mm.
