Product Details

The MAX22190 evaluation system (EV system) provides the hardware and software necessary to evaluate the MAX22190 Octal Industrial Digital Input device with Diagnostic features. The MAX22190 EV kit has Pmod™ compatible connector for SPI communication. The EV system includes the USB2PMB2# adapter board that receives commands from a PC through the USB port to create an SPI interface for communication between the software and the MAX22190 on the EV kit.

The EV system includes a graphical user interface (GUI) that provides communication between the target device and the PC. The MAX22190 EV kit has two MAX22190 devices (U1 and U2) that can operate in multiple modes, as shown in Figure 1:

Single-Channel Mode: The USB2PMB2# adapter connects to either U1 or U2 on the EV kit, depending on which channel is preferred, and selected using the on-board jumpers.
Independent Slave Mode: The USB2PMB2# adapter uses two chip-select signals (active-low CS1 and active-low CS2) to control each chip through a single connector/GUI interface.
Daisy-Chain Mode: The USB2PMB2# adapter connects to both U1 and U2 through the MAX14483 Digital Isolator, and SDO from U1 connects to SDI of U2. Both U1 and U2 are controlled from a single SPI interface.

Features and Benefits

Easy Evaluation of the MAX22190
Powered from Single 3.0-5.5V Logic Supply, Without the Need for 24V Field Supply
Configured for IEC 61131-2 Type 1 and Type 3 Sensor Inputs
Proven PCB Layout
Works with USB2PMB2# or USB2GPIO# Adapter and Munich GUI Software

Product Details

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.
