ADI ADP5585, ADP5589 GPIO Port Expander and Keypad Matrix Controllers

Analog Devices announced their ADP5585 and ADP5589 general-purpose input/output port expander and keypad matrix controllers. The ADI GPIO devices feature built-in programmable logic devices, two programmable reset generators, and low active current drain. The ADP5585 and ADP5589 are ideal for devices that require expanded I/O lines or mechanical keypads up to QWERTY size. Both devices are available now in small LFCSP and WLCSP packages. The ADP5585 is priced at $0.75 each in lots of 1000. The ADP5589 is priced at $1.20 each (1,000 quantity).
