Pin Function Table
Description
The Microchip Technology Inc. 25XX128
(1)
is a
128 Kbit Serial Electrically Erasable PROM. The mem-
ory 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.
