Microchip Technology 25LC640 serial EEPROM, part number 25LC640-P, offers 65536 bits of non-volatile memory organized as 8K words by 8 bits. This CMOS device operates via a SPI serial interface, supporting clock frequencies up to 2.00000 MHz. The 25LC640 series is designed for applications requiring robust data retention exceeding 200 years and features 4KV ESD protection. Endurance is rated at 1 million write cycles. Operating voltage ranges from 2.5V to 5.5V, with a nominal 2.7V. This through-hole component is housed in a PDIP8 package, with a terminal pitch of 2.54mm. Applications include industrial control, automotive systems, and consumer electronics. Write protection can be implemented via hardware or software means.
