Microchip 25AA320A-I/SN Eeprom 32 Kbit 4K x 8bit Serial SPI 10 MHz Soic 8 Pins

The 25AA320A-I/SN is a 32kB serial Electrically Erasable Programmable Read-Only Memory (EEPROM) 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 to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts.
