Pmod-IOXP (Pmod-IOXP)

The PmodIOXP is an I/O expansion module powered by the Analog Devices ADP5589. It functions as an I/O port expander and keypad matrix decoder, and uses a standard 8-pin I2C connector allowing it to communicate with a system board via I2C.

All communications with the device must specify a register address and a flag indicating whether the communication is a read or a write. This is followed by the actual data transfer.

Device configuration is performed by writing to control registers within the device. Input and event data is accessed by reading certain device registers.

A full list of registers and their functionality, as well as communication specifications, is found in the ADP5589 datasheet available on the Analog Devices website.
  • I/O port expander that communicates with a host via an I2C interface
  • 16-element FIFO for event recording
  • 19 configurable I/Os
  • Keypad decoding for matrices up to 11x8
  • PWM generator
  • Open-drain interrupt output
  • Dual Programmable logic blocks
  • Debouncing on IOs
  • Ships with a 10" 4-pin MTE cable
