Chapter 1 SNVU166 – FEBRUARY 2013 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.
Step-by-step Instructions for Operation and Troubleshooting www.ti.com 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: • • 1.4 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.
Chapter 2 SNVU166 – FEBRUARY 2013 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.
