New from Analog Devices are the ADP5585 and ADP5589 GPIO (general-purpose input/output) port expander and keypad matrix controllers for devices that require expanded I/O lines or mechanical keypads up to QWERTY size. The devices feature low active current drain and integrated programmable logic/PWM (pulse-width modulator). They consume less than 30 μA when keys are pressed and less than 1 μA when the keys are idle.
The ICs simplify interface connectors by saving up to 10 I/O lines (ADP5585) and 19 I/O lines (ADP5589) to the main processor. Both support multiple, simultaneous key press detection and communicate presses and releases in a chronological order via a 16-Byte FIFO. In addition to the built-in programmable logic devices, two programmable reset generators allow designers to program keys, GPIOs and/or logic changes to generate a reset signal to restart a locked up processor.
The controllers handle all key scanning and decoding functions and use an interrupt line to flag the main processor when new key events have occurred. Their FIFO registers store up to 16 events which are then read back by the processor through an I²C-compatible interface. Evaluation boards and Linux software drivers are available to provide the necessary tools to implement new designs quickly.
