Microchip Technology 25LC640 serial EEPROM, part number 25LC640-ST, offers 65536 bits of memory organized as 8K x 8. This CMOS device operates synchronously via an SPI interface, supporting clock frequencies up to 2.00000 MHz. It features robust data retention exceeding 200 years and 1 million endurance cycles, with 4KV ESD protection. The 25LC640-ST is housed in a PDSO8 (TSSOP8) package with a 0.650mm terminal pitch, suitable for surface mount applications. Operating voltage ranges from 2.5V to 5.5V. Write protection is supported through both hardware and software mechanisms. This component finds application in industrial control, automotive systems, and consumer electronics where reliable non-volatile data storage is critical.
