The Microchip Technology 25AA640-ST is a 64-kilobit serial EEPROM organized as 8K words by 8 bits. This CMOS device operates via the SPI serial bus, supporting clock frequencies up to 1 MHz. It features robust data retention exceeding 200 years and 1 million endurance cycles, along with 4kV ESD protection. The 25AA640 series is suitable for applications requiring reliable non-volatile data storage, including industrial control, consumer electronics, and automotive systems. It is housed in a space-saving 8-lead PDSO package with a 0.65mm pitch and a maximum seated height of 1.2mm. The device supports a wide supply voltage range from 1.8V to 5.5V and offers both hardware and software write protection. Standby current is a minimal 1µA.
