GENERAL DESCRIPTION
The ADP5586 is a 10-input/output port expander with a built-in
keypad matrix decoder, programmable logic, reset generator, and
pulse generators. Input/output 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 ADP5586 handles all key scanning and decoding and can
flag the main processor, via an interrupt line, that new key events
have occurred. GPI changes and logic changes can also be tracked

as events via the FIFO, eliminating the need to monitor different
registers for event changes. The ADP5586 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 ADP5586 eliminates the need for the main processor to
monitor the keypad, thus reducing power consumption and/or
increasing processor bandwidth for performing other functions.
The programmable logic functions allow common logic require-
ments to be integrated as part of the GPIO expander, thus saving
board area and cost.
