Hardware Description

The ISL21400 evaluation board is designed to be connected

to the Intersil ISLUSBCEVAL1Z evaluation board. There is a

connector (USB Board) on the ISL21400 evaluation board

which mates with the ISLUSB evaluation board.

The ISL21400 device is mounted on top of the board on a

copper pad with vias to a copper pad on the bottom. This

provides good thermal conductivity to the underside of the

board. The surrounding area has copper on both top and

bottom of the board in an area 0.375”x0.375”, with many vias

for conducting heat from the underside of the board to the

top side.

The ISL21400 evaluation board has all address pins shorted

to ground; therefore, only slave address 50h can be

selected.

The ISL21400 device on the board is powered by the 3.3V

regulator from the ISLUSB evaluation board. If a different

evaluation board and connect the desired V

connector on the ISL21400 evaluation board.

Software Guide

Installation

Insert the CD into the PC CD drive. Do not connect the

evaluation board to the PC with USB cable. Click on

ISL21400 Customer Interface Ver 2.0.exe to start the

installation program. Follow the instructions on the installer

windows and finish completion.

Connect the evaluation board with a USB cable to the PC.

The “Found New Hardware Wizard” in Microsoft Windows

will pop up. Please follow the following:

1. Select “Install the software automatically

(Recommended)”, then click Next.

2. Wait for the Windows to find the driver installed with

“ISL21400 Customer Interface Ver 2.0.exe”, then click

Finish.

After the driver installation is completed, please start the

evaluation software by going to START->All Program-

>Intersil-> ISL21400 Customer Interface->ISL21400

Customer Interface Ver 2.0 to start the program. You may

also make a shortcut to the .exe file and place it on your

desktop.

In the upper right corner of the ISL21400 program window

(see Figure 1), there is a small window for selecting the

slave address. The slave address contains 4-bits of device

ID, which are fixed at 0101, followed by the 3 individual

address bits. The setup is as follows:

The address bits are the same as that selected by the

hardware address pins on the IS21400 device in the

evaluation circuit. The ISL21400 evaluation board has the

address pins tied to ground (address = 50h). The last bit of

the slave byte is the read/write bit and is set to zero by this

selection window (it will be changed by the read/write

commands). If other ISL21400 devices accessed using this

software are configured with a non-zero address, the slave

address will be an even number.

The software provides a window for displaying the contents

of all registers. A simple read can be done by clicking on the

Read All button. This will perform a page read and display

the data of each register. Clicking on an individual bit in this

window will select that bit to change in that register, and the

hex value will be shown next to the register. By clicking the

Write button next to the register it will write the selected

value to the register. By clicking Write All, all registers will be

written by the program. Bright and released Yellow for a bit

indicates a zero, dim and pressed yellow indicates a one.

The “QUIT” button is used to suspend execution of the

program.
