The Microchip Technology AT25640B-CUL-T is a 64Kb serial CMOS EEPROM organized as 8K x 8 bits. This device supports the SPI serial bus interface, operating at clock frequencies up to 20 MHz. It features flexible supply voltage operation, including 4.5V to 5.5V, and also functions at 2.5V (up to 10 MHz) and a minimum of 1.8V (up to 5 MHz). With a data retention of 100 years and an endurance rating of 1 million write cycles, the AT25640B offers robust data storage. Write protection is supported through both hardware and software mechanisms. The component is housed in a compact 8-lead PBGA package (R-PBGA-B8) with a 0.75mm terminal pitch. Applications for this EEPROM include industrial control systems, automotive electronics, and consumer devices requiring non-volatile data storage.
