Description

The Microchip Technology Inc. 25AA040/25LC040/25C040 (25xx040*) is a 4K bit serial Electrically Eras-able 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 25AA040/25LC040/25C040 (25xx040*) is paused, transi-tions 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).
