Description:
The Microchip Technology Inc. 25AA080C/D,
25LC080C/D (25XX080C/D^*) are 8 Kbit Serial Electri-
cally 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 pack-
aging including 8-lead MSOP, TSSOP, and 2x3 TDFN.
All packages are Pb-free and RoHS compliant.
