Description:

The

25LC160C/D (25XX160C/D

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, transi-

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

Chip Select, allowing the host to service higher priority

interrupts.

The 25XX160C/D is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packaging including 8-lead MSOP, TSSOP, and 2x3

TDFN. All packages are Pb-free and RoHS compliant.
