Description:

The Microchip Technology Inc. 25AA256/25LC256

(25XX256*) are 256 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)

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.

The 25XX256 is available in standard packages includ-

ing 8-lead PDIP and SOIC, and advanced packaging

including 8-lead DFN and 8-lead TSSOP.
