Ranges

25C080 (25XX080^*) are 8 Kbit Serial Electrically

Erasable PROMs. The memory is accessed via a

simple Serial Peripheral Interface™ (SPI™) compati-

ble 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.

Features:

Communication to the device can be paused via the

hold pin (HOLD). While the device is paused, transi-

tions on its inputs will be ignored, with the exception of

chip select, allowing the host to service higher priority

interrupts.
