25AA080/P is an 8-Kbit Serial EEPROM device from Microchip Technology. It is a nonvolatile memory device with an SPI serial bus interface. It is used to store up to 128 bytes of user data or program code in a serial data format. The 25AA080/P is an 80-pin SOIC package with a maximum operating voltage of 6.25V. It has native 4-wire SPI, allowing for maximum flexibility and faster throughput than other microcontroller EEPROMs. The 25AA080/P supports full duplex transactions, allowing data to be written, read or erased in the same transaction. It has a typical write time of 10ms and an endurance of 1,000,000 write/erase cycles.
