The MAX22190 peripheral module provides the hardware to evaluate the MAX22190 Octal Industrial Digital Input. Refer to the MAX22190 IC data sheet for detailed information regarding operation of the IC. The module takes advantage of the features in the MAX22190 allowing it to be powered from a single low voltage logic supply (3.0-5.5V) without the need for a 24V field supply. Note that this module provides a subset of the MAX22190 features – for greater flexibility refer to the MAX22190 EV kit. The module can be used in various ways; the device is configured by SPI interface. Maxim sells low-cost USB2PMB1#, USB2PMB2#, and USB2GPIO# adapter boards that use the Munich GUI software for communication through a USB cable generating SPI communication with the MAX22190. This is not included with this board. Alternatively, any microcontroller or FPGA with a 12-pin Pmod™-compatible connector can be used. Another option for the user is to wire-wrap a temporary connection from their system to the pins on connector X1. For these later two options the user needs to write their own control software.
The Pmod PCB dimension is just 45mm long x 20mm wide, with the width determined by the size of the X1 and X2 connectors.
