.

is a 4 Kbit serial Electrically Erasable PROM. 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 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. Also, write operations to the device can be disabled via the write-protect pin WP.
