Microchip Technology's 25LC640 is a 64-kilobit serial CMOS EEPROM device organized as 8K x 8 bits. This component supports the SPI serial bus interface, operating at clock frequencies up to 2 MHz. It features a wide operating voltage range from 2.5V to 5.5V and boasts an endurance of 1,000,000 erase/write cycles with data retention exceeding 200 years. The 25LC640 is housed in an 8-lead PDSO (TSSOP) package with a 0.65mm terminal pitch, suitable for surface mount applications. Write protection is available through both hardware and software mechanisms. This EEPROM finds application in various industrial, automotive, and consumer electronics systems requiring non-volatile data storage.
