GENERAL DESCRIPTION

The

decoder designed for QWERTY type phones that require a large

keypad matrix and expanded I/O lines. I/O expander ICs are

used in mobile platforms as a solution to the limited number of

GPIOs available on the main processor.

The ADP5589 handles all key scanning and decoding and can

flag the main processor via an interrupt line that new key events

have occurred. The ADP5589 is equipped with a FIFO to store
