MAX11300 Evaluation Kit

General Description

The MAX11300 evaluation kit (EV kit) provides a proven

design to evaluate the MAX11300 20-port program-

mable mixed-signal I/O with 12-bit ADC, 12-bit DAC,

analog switches, and GPIO. The EV kit also includes

Windows XP

-, Windows Vista

-, Windows

7-, and

Windows 8.0-/8.1-compatible software that provides a

simple graphical user interface (GUI) for exercising the

features of the IC.

The EV kit comes with a MAX11300GTL+ installed.

software and PCB layout with a B suffix (e.g., INTB).

Quick Start

Required Equipment

● EV kit (USB mini-B cable included)

● Windows XP, Windows Vista, Windows 7, Windows

8.0, or Windows 8.1 PC, running .NET v4, with a

spare USB port

● ±12.5V DC at 500mA dual-output DC power supply

● Digital voltmeter (DVM)

Note: In the following sections, software-related items are

identified by bolding. Text in bold refers to items directly

from the EV kit software. Text in bold and underlined

refers to items from the Windows operating system.

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

1) Visit www.maximintegrated.com/evkitsoftware to

download the latest version of the EV kit software,

MAX11300EVKitSetupV1.0.zip. Save the EV kit soft-

ware to a temporary folder and uncompress the ZIP

le.

2) Install the EV kit software and USB driver on your com-

puter by running the MAX11300EVKitSetupV1.0.exe

program inside the temporary folder. The program

files are copied to your PC and icons are created in

the Windows Start | Programs menu. During soft-

ware installation, some versions of Windows may

show a warning message indicating that this software

is from an unknown publisher. This is not an error

condition and it is safe to proceed with installation.

Administrator privileges are required to install the

USB device driver on Windows. Note: The software

requires .NET Framework v4. If this framework is not

detected during installation, the installer launches

dotNetFx40_Full_setup.exe to install it. Internet ac-

cess may be required to install the .NET Framework

v4 if it is not already installed.

3) Verify that all jumpers are in their default positions, as

shown in Table 1, Table 2, Table 3, and Table 4.

4) Configure the power supply for ±12.5V DC output

(typical load current is 50mA) (be sure to keep AVD-

DIO-AVSSIO within rated supply range).

Double-click in the Configured As cells to jump directly to the Pin Configuration tab (Figure 5) for the corresponding pin. Each row represents one of the PIXI ports or one of the temperature sensors. Some configurations enable DAC Evaluates: MAX11300 Out or GPO Out controls, or provide ADC or GPI input values.

MAX11300 Evaluation Kit Evaluates: MAX11300 The PIXI ports can be viewed and manually adjusted from the Pin Configuration tab. Selecting the pin function affects the choices in the other four fields. The software does not attempt to validate the configuration. The GPIO1–GPIO3 pins are spare outputs from the MAXQ2000 microcontroller that can be optionally used to support external diagnostic testing. They are not part of the MAX11300.

Write is effective by the Evaluates: MAX11300 Write button. Refer to the MAX11300 IC data sheet for the meaning and format of the various registers. The History tab provides a diagnostic log of the commands sent to the EV kit. Figure 6 Figure 6. Registers Tab www.maximintegrated.

Evaluates: MAX11300 MAX11300 Evaluation Kit Detailed Description of Hardware Connecting to User-Supplied Circuitry The EV kit connects to external, user-supplied circuitry through header J1 or J2. These two headers have the same signals; J1 is for vertical 50-pin ribbon-cable connection and J2 is for right-angle connection to a sideboard by standard 0.100in right-angle pins. The MAX11300 EV kit uses an on-board MAXQ2000 microcontroller (U120) to send SPI commands to the device.
