The Microchip Technology Inc. 25AA080A/B,
25LC080A/B (25XX080A/B*) 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, transitions
on its inputs will be ignored, with the exception of
chip select, allowing the host to service higher priority
interrupts.
The 25XX080A/B is available in standard packages
including 8-lead PDIP and SOIC, and advanced
packaging including 8-lead MSOP, and 8-lead TSSOP.
All packages are Pb-free and RoHS compliant.
