EEPROM 2Kbit SPI Serial 25AA02E48-I/SN 8-SOIC

The 25AA02E48-I/SN is a 2Kbit serial Electrically Erasable Programmable Read-only Memory (EEPROM) from Microchip. The memory is accessed via a simple serial peripheral interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input. Communication can be paused via the hold pin (hold), allowing the host to service higher priority interrupts.
