Introduction

The TCA7408-5405EVM is designed to show the used of multiple TI products on a single evaluation
board. It shows how the single-wire 5-bit output expander TCA5405 is used to generate LED blinking
functions. The Single wire interface is implemented using a single GPIO port on the MSP430, and very
simple firmware embedded in the device. The TCA7408 GPIO expander is used to an input handler, that
detects Key presses and notifies the MSP430. The EVM also has the TPL0401 that is used for RGB color
mixing in conjunction with the TLC59108.
