Evaluates: MAX22190 MAX22190PMB General Description Features The MAX22190 peripheral module provides the hardware Easy Evaluation of the MAX22190 to evaluate the MAX22190 Octal Industrial Digital Input. Powered from Single 3.0-5.5V Logic Supply, Without Refer to the MAX22190 IC data sheet for detailed the Need for 24V Field Supply information regarding operation of the IC. The module Configured for IEC 61131-2 Type 1 and Type 3 takes advantage of the features in the MAX22190 Sensor Inputs allowing it to be powered from a single low voltage logic supply (3.0-5.5V) without the need for a 24V field supply. Proven PCB Layout Note that this module provides a subset of the MAX22190 Works with USB2PMB2 or USB2GPIO Adapter features for greater flexibility refer to the MAX22190 EV kit. and Munich GUI Software The module can be used in various ways the device is configured by SPI interface. Maxim sells low-cost USB2PMB1 , USB2PMB2 , and USB2GPIO adapter MAX22190PMB EV Kit File boards that use the Munich GUI software for communication FILE DECRIPTION through a USB cable generating SPI communication Munich GUI Software for use with the MAX22190. This is not included with this board. Munich GUISetupV2.21.ZIP with the USB2PMB adapter 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 Ordering Information appears at end of data sheet. X2 connectors.
