Microchip Technology's 25LC640T-E-ST is a 64-Kbit serial CMOS EEPROM featuring an 8K x 8 memory organization. This device operates via a standard SPI serial interface, supporting clock frequencies up to 3 MHz. It offers robust data retention exceeding 200 years and endurance of 100,000 erase/write cycles. The 25LC640T-E-ST is housed in an 8-pin PDSO (TSSOP) package, suitable for surface-mount applications. Its operating voltage range is 4.5V to 5.5V, with a typical supply current of 5 mA. This component finds application in industrial, automotive, and consumer electronics sectors requiring reliable non-volatile data storage. Write protection is supported through both hardware and software mechanisms.
