Description:
The Microchip Technology Inc. 25AA160C/D,
25LC160C/D (25XX160C/D
*
) are 16 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, 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.

NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for an
extended period of time may affect device reliability.
