Microchip Technology's 25AA640-P is a 64Kbit serial CMOS EEPROM organized as 8K words by 8 bits. This component operates with an SPI serial interface, supporting clock frequencies up to 1 MHz. It features a wide operating voltage range from 1.8V to 5.5V and offers robust data retention exceeding 200 years. The 25AA640-P includes 4KV ESD protection and a remarkable endurance rating of 1 million write cycles. Hardware and software write protection mechanisms are incorporated for data integrity. This device is housed in a PDIP8 (Plastic Dual In-line Package) with through-hole mounting and a terminal pitch of 2.54mm. It is commonly utilized in industrial control, automotive systems, and consumer electronics applications requiring non-volatile data storage.
