Microchip | 25LC080A-I/SN

The 25LC080 (25XX080*) are 8 Kbit Serial Electrically Erasable PROMs. 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(bar)] input.

Communication to the device can be paused via the hold pin [HOLD(bar)]. 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.
