USB2GPIO# Adapter Board

Evaluates: USB2GPIO

General Description

The USB2GPIO# adapter board is designed to work
with Maxim’s Munich GUI and to connect to various EV
kit or Pmod boards with Pmod™ compatible connectors
for I2C/SPI/GPIO communication to test and evaluate
different Maxim ICs. This document explains how the
USB2GPIO# adapter board receives commands from
a laptop through the USB to create an I2C/SPI/GPIO
interface. The Maxim USB2GPIO# board requires the
Munich GUI which can be downloaded from Maxim’s
website free of charge.

The USB2GPIO# design is powered directly from the USB
bus power (5V) and integrates two low-power, 1.2A, PWM
step-down DC-DC converters (MAX1556) to provide
programmable VCC voltages of 1.8V, 2.5V, 3.3V, or 5.0V.
A dual, high-speed, USB-to-multipurpose UART/FIFO IC
(FT2232HQ), high-speed USB switches (MAX4983), and
a 4K MICROWIRE-compatible serial EEPROM are the
other ICs on this adapter board.

USB2GPIO# is designed to supersede USB2PMB1# and
USB2PMB2# adapters and includes two connectors;
connector X3 is a 12-pin connector which supports either
I2C with 6 GPIO pins, or SPI with 4 GPIO pins, and is
fully compatible with previous adapters and low-pin count
EV kit or Pmod boards. This connector is controlled from
the Munich GUI. The addition of another connector, X2,
which is a 20-pin connector allows either 16 extra GPIO
connections or a second SPI port and 12 extra GPIO
connections. This 20-pin connector is NOT controlled by
Munich GUI but is for use with future EV kits and will be
controlled by the relevant EV kit GUIs.

This USB2GPIO# adapter board can be used to enable
USB-to-I2C/SPI interface for any Pmod-compatible plug-in
peripheral modules such as the Maxim MAX14001PMB#,
and MAXREFDES12 – Corona reference designs. In
addition, it can be ordered together as an evaluation
system (EV system) with different EV kits, such as
MAX14001EVKIT#. Note that an “EV system” is an EV kit
combined with an interface board, such as a USB2GPIO#
and EV kit GUI software. Ordering information for EV
systems is included in the EV kits’ corresponding data
sheet. Refer to the appropriate EV kit data sheet for quick
start and detailed operating instructions.

The USB2GPIO# has been tested on Windows® 7,
Windows 8, and Windows 10 system using Munich GUI,
Version 2.17 or later.

Features

● USB-to-I2C/SPI/GPIO Interface

Quick Start

Required Equipment

● PC with Windows OS (Windows 7, Windows 8, or

Windows 10) with a USB port

● USB2GPIO# board

● A-to-Micro-B USB cable (not supplied)

● Munich software V2.17 or later

● Supported I2C or SPI interface device for communication

like MAX14001PMB# board

Procedure

The USB2GPIO# is fully assembled and tested. Follow
the steps below to verify board operation:

1) Go to www.maximintegrated.com/evkitsoftware
to download the most recent version of the Munich
GUI software, MUNICH GUI. Save the software to a

temporary folder and decompress the Munich_GUI-

SetupV2.17.zip le.

2) Connect the USB cable between the USB2GPIO#
board and the PC; the USB driver is installed
automatically.

3) Ensure that the companion SPI interface device’s
jumper settings are correct. Refer to your companion
device’s documentation.

4) Connect the USB2GPIO# board’s 2 x 6-pin, right­angle connector to the companion device’s 2 x 6-pin,
right-angle header, as shown in Figure 2.

5) Once the USB2GPIO# board is connected to the
companion device, open the MUNICH GUI.exe
(double-click) software.

6) Start the Munich GUI software and select the tab
sheet that corresponds to the companion device.
Follow instructions in the companion device data
sheet to test it in conjunction with USB2GPIO#.

Detailed Description of Hardware

The USB2GPIO# board uses the FT2232HQ (U1), a USB

2.0 high-speed (480Mbps)-to-UART/FIFO IC, to process
commands sent by a program running on the PC. Each

particular EV kit has its own custom software specic

to that kit. The operation of this board is USB-to-dual­channel I2C and SPI engine with additional GPIO channels.

The subsystem block diagram and simplied power tree

are shown in Figure 3.

The VCCIO and +3.3V voltage supplies are generated

by two MAX1556ETBs (U5 and U6), 1.2A, highly efcient

PWM step-down DC-DC converters. The 5V supply volt­age input for these ICs is provided by the Micro-USB
supply terminal available from the laptop. The 3V3 sup­ply provides power to the FDTI chip’s VREGIN pin and

its internal oscillator through an LC lter, and the 4K

MICROWIRE EEPROM (93LC66BT). The USB-to-I2C/SPI
engine is powered by 3.3V at the VREGIN pin and the core
voltage of 1.8V for the IC is generated at VREGOUT. This
VCORE is used within the FTDI IC itself for its internal logic
processes and there is an external 12MHz crystal across
OSCI and OSCO pins of the FTDI IC. See USB2GPIO#

Adapter Board Schematic for details.

Pmod and Connector Supply Voltages

The USB2GPIO# is designed to supply power (V_OUT) to
external boards through the connectors X2 and X3. This

voltage is dened by the type of board connected to X3,

and when the user selects that tab in the Munich GUI,
V_OUT is automatically set to the correct level, either

1.8V, 2.5V, 3.3V, or 5.0V.

board which aligns to the pin conguration for the
connector found on companion Pmod boards such as
MAX14001PMB#. The connector type is female on the
USB2GPIO# board and male type on the companion
Pmod boards.

Figure 5 shows the pin configuration for the 20-pin GPIO-

Figure 6 shows the top view of the USB2GPIO# board,

with the different connectors and the pin 1 identifiers.
Note that there are no jumpers or shunts on this
board, all configuration is done under software control.
Care should be taken to only insert the boards in the
correct way as the connectors are not keyed to avoid false

insertions—reversing the connections (by turning the
Pmod board upside down, for example) may result in
damage to the USB2GPIO# or the companion board. Two
LEDs are included to indicate if the X3 Pmod connector is
configured as SPI or I2C.
