The Microchip Technology Inc. 25AA160A/B,
25LC160A/B (25XX160A/B * ) 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 25XX160A/B is available in standard Pb-free pack-
ages including 8-lead PDIP and SOIC, and advanced
packaging including 8-lead MSOP, and 8-lead TSSOP.
