8 Kbit SPI EEPROM – non-volatile storage for configuration and calibration data
The Microchip AT25080B-XHL-T is an 8 Kbit serial EEPROM organized as 1 K x 8 bits, accessed through an SPI interface running at up to 20 MHz. It stores configuration parameters, calibration constants, and firmware look-up tables that must survive power cycles. The non-volatile memory format and 5 ms write cycle time per word or page suit applications where data is updated infrequently but must be retained across power loss.
