*25XX080A/B is used in this document as a generic part
number for the 25AA080A/B, 25LC080A/B.
Description
The
25LC080A/B
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 25XX080A/B is available in standard packages
including 8-lead PDIP and SOIC, and advanced
packaging including 8-lead MSOP, and 8-lead TSSOP.
Pb-free (Pure Matte Sn) finish is also available.
