Microchip Technology’s 25AA640AX-I-ST is a 64 Kbit serial EEPROM, organized as 8K x 8 bits. This CMOS device features an SPI-compatible interface, supporting clock frequencies up to 10 MHz. It offers a wide operating voltage range from 1.8V to 5.5V, with a nominal supply voltage of 2.5V. The component provides 200 years of data retention and 1,000,000 write cycles per byte endurance. It supports hardware write protection and operates within an industrial temperature range of -40°C to +85°C. The 25AA640AX-I-ST is housed in a Pb-free, 8-lead TSSOP package with a 0.65mm terminal pitch. This serial memory solution is suitable for applications in automotive, industrial control, and consumer electronics where reliable data storage is critical.
