Overview

The ADP5585ACPZ-00-R7 series 10 I/O port Expander with a built in keypad matrix decoder, programmable logic, reset generator and PWM generator. The I/O expander 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 ADP5585ACPZ-00-R7 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. It is equipped with a FIFO to store up to 16 events. Events can be read back by the processor via an I²C-compatible interface. It frees up the main processor from having to monitor the keypad, thereby reducing power consumption and/or increasing processor bandwidth for performing other functions.
