Description:

The Microchip Technology Inc. 25AA640A/25LC640A

(25XX640A*) are 64 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 sep-

arate 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, transi-

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

Chip Select, allowing the host to service higher priority

interrupts.

The 25XX640A is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packaging including 8-lead MSOP, 8-lead TSSOP, DFN

and TDFN.
