GENERAL DESCRIPTION
The ADP5589 is a 19 I/O port expander with built-in keypad
matrix decoder, programmable logic, reset generator, and
PWM generator. I/O expander ICs are used in portable devices
(phones, remote controls, and cameras) and nonportable
applications (healthcare, industrial, and instrumentation). I/O
expanders can be used to increase the number of I/Os available
to a processor or to reduce the number of I/Os required
through interface connectors for front panel designs.
The ADP5589, which handles all key scanning and decoding,
can flag the main processor via an interrupt line when new key
events have occurred. In addition, GPI changes and logic
changes can be tracked as events via the FIFO, eliminating the
need to monitor different registers for event changes. The
ADP5589 is equipped with a FIFO to store up to 16 events.
Events can be read back by the processor via an I2C compatible
interface.
The ADP5589 frees up the main processor from having to
monitor the keypad, thereby reducing power consumption
and/or increasing processor bandwidth for performing other
functions.
The programmable logic functions allow common logic
requirements to be integrated as part of the GPIO expander,
saving board area and cost.
