The Microchip AT25020B-SSHL-T is a 2Kbit serial EEPROM with an SPI interface clocked up to 20 MHz. That clock rate means the part can shift a full 256-byte page in about 100 µs, leaving the bus free for the rest of the system. Organized as 256 x 8 bits, it is sized for configuration storage, calibration constants, or small lookup tables in embedded designs.
