Introduction

The Texas Instruments (TI) LM8330 evaluation module (EVM) helps designers evaluate the operation and

performance of the LM8330 I2C ™ Keyscan Controller. The LM8330 keyscan operates from a 1.8V supply

and supports 7- and 10-bit I2C addressing in both Standard (100 kHz) and Fast (400 kHz) modes. It offers

exceptional ESD performance designed to tolerate IEC6100-4-2 level 4 ±8 kV direct contact. With 20

configurable GPIO pins, it can support 12x8 keypad array. This operation frees the processor from

scanning the keypad for presses and releases, thus saving power and bandwidth of the system.

The LM8330EVM serves as an I2C interface adapter between a host PC, the LM8330, and/or other I2C-

compatible devices externally connected to the EVM. The communication between the EVM and host PC

is via USB (through a standard type-A to type-B USB cable), while the communication between the EVM,

the LM8330, and/or other slave devices is via I2C bus. The EVM converts communication transactions

between the USB and I2C. The LM8330EVM is a USB powered device with no external power supply

required.

1.1 List of Hardware Items for Operation

To operate the LM8330EVM, the following items are required:

• The LM8330EVM

• Standard type-A to type-B mini-USB cable

• PC with Windows XP, Win7 or later operating system installed

The LM8330EVM contains a USB-to-I2C convertor (MSP430F5529), USB ESD Protection, LDOs, Level

Shifters, and the LM8330.

1.2 List of Software Items for Operation

In addition to the hardware items listed in Table 1-1, this software is required:

• Demo GUI Software (LM8330.exe)

The software can be downloaded from the TI website at www.ti.com.

The EVM is recognized by a PC as a generic human interface device (HID), which is supported by the

built-in USB/HID drivers of the Windows XP or later operating system. Therefore, it is plug-and-play, and

no proprietary USB driver is required.

Step-by-step Instructions for Operation and Troubleshooting

1.3 Step-by-step Instructions for Operation and Troubleshooting

After downloading and installing the GUI demo software, follow these steps to operate the EVM:

• Plug the USB cable into both the PC and the EVM and wait for the LED to illuminate.

Troubleshooting: if the LED does not illuminate after 30 seconds, follow these steps:

– Verify that the USB cable is securely connected.

– If the connection is secure, try a different USB port.

– If the problem persists, try rebooting the PC.

– If the problem still persists, try a different USB cable.

– If these steps did not solve the problem, contact TI technical support for help.

• Run the LM8330EVM GUI software and follow the instructions for the GUI (refer to Chapter 3).

1.4 Hardware Uninstall Instructions

Unplug the EVM from the USB port to uninstall the hardware from the host PC.

1.5 Software Uninstall Instructions

For Windows operating system, go to Control Panel > Add or Remove Programs to remove the LM8330

GUI software.

EVM Configuration and Description

2.1 EVM Options

The hardware is based on the TI MSP430 16-bit, ultra-low power, mixed signal micro-controller with

integrated USB. The PCB is a four-layer board with components mounted on both top and bottom layers

(refer to SCHEMATIC).

2.2 LED (D1) Indication of USB Attached

A green LED is mounted adjacent to the USB (J3) connector on the EVM. Every time the USB interface

adapter is attached to a PC via a USB cable, and if the host PC detects it and goes through enumeration

successfully, the embedded firmware illuminates the LED (D1); otherwise, the LED remains off. After

unplugging the USB cable, the LED turns off immediately.

2.3 Input/Output Connector Description

J2 - Input/Output is the keypad IO connector. This connector provides the connection between the keypad

and the LM8330.

J3 - Input is the USB input connector. This connector provides USB data communication, 5V Power In and

ground (GND) connections.

J4 - Input/Output is the I2C input/output connector. This connector provides access to the I2C SCL and

SDA signals for monitoring from an external device.

2.4 Test Point Connectors

Test point connectors TP1 through TP4 allow the users to verify internal power rails on the LM8330EVM.

describes the functions of all of the test points on the EVM.
