Description
The Microchip Technology Inc. 25AA080C/D,
25LC080C/D (25XX080C/D
*
) are 8 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 25XX080C/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.
