The Microchip Technology 25C640 is a 64 Kbit serial CMOS EEPROM organized as 8K x 8 bits. This device supports the SPI serial bus interface, operating at clock frequencies up to 3 MHz. It features robust data retention exceeding 200 years and 10 million endurance cycles. Integrated 4KV ESD protection enhances reliability. The 25C640 is housed in an 8-pin PDSO (SOP8) package with a 1.27mm pitch, suitable for surface mount applications. Its operating voltage range is 4.5V to 5.5V, with a standby current of 5µA maximum. Applications include industrial control systems, consumer electronics, and automotive systems requiring non-volatile data storage. Hardware and software write protection mechanisms are included.
