General Description

The ADP5585 is a 10 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator.

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.

Key Features

16-element FIFO for event recording 10 configurable I/Os allowing functions such as Key pad decoding for a matrix of up to 5 × 5 11 GPIOs (5 × 6) with ADP5585ACxZ-01-R7 models Key press/release interrupts GPIO functions GPI with selectable interrupt level 100 kΩ or 300 kΩ pull-up resistors 300 kΩ pull-down resistors GPO with push-pull or open-drain Programmable logic block PWM generator Internal PWM generation External PWM with internal PWM AND function Reset generators I2C interface with fast m.
