Microchip Technology's 25AA640 is an 8K x 8 serial EEPROM memory device, part number 25AA640AT-I-MS. This CMOS device operates via a SPI-compatible serial interface with a maximum clock frequency of 10 MHz. It offers a substantial memory density of 64 Kbits, organized as 8192 words of 8 bits each. The device supports a wide operating voltage range from 1.8V to 5.5V, with a typical programming voltage of 2.5V. Endurance is rated at 1 million write cycles, and data retention exceeds 200 years.
The 25AA640AT-I-MS is housed in a plastic/epoxy small outline package (PDSO8, also known as SOP8) with a 0.65mm terminal pitch, suitable for surface mounting. It features hardware and software write protection. This component is designed for applications requiring reliable non-volatile data storage, including automotive systems (AEC-Q100 qualified), industrial controls, and consumer electronics. Operating temperature range is -40°C to +85°C.
