Return to CC256x EVM Platform

Introduction

The EZ430-RF256x is a complete TI Bluetooth evaluation and demonstration tool for the MSP430 and CC256x that includes all the necessary hardware and software in a convenient USB stick.

  • You can follow this link to see Step by Step out of box instructions.
  • We also have a short FAQ for troubleshooting the EZ430-RF256x Kit.
  • The EZ430-RF256x can be used as a stand-alone development tool. Additionally, the RF256xT target board also may be detached from the debugging interface and integrated into another design by removing the plastic enclosure.

This platform is composed of the CC256x Bluetooth device and the msp430f5438A microcontroller. Additional key terms. The tool also comes with a sample PC game that you can play using the CC256x target board as a remote controller.
The table below depicts briefly the hardware and software partition of this platform.


Device Hardware Software

  • BT Firmware
  • MAC/PHY




Please Note:

  • The EZ430-RF256x is intended as a software and end design evaluation platform. It is not intended for hardware evaluation purposes and does not contitute a reference hardware design. As such, TI does not provide schematics and/or layout information. Customers wishing to leverage TI's Bluetooth connectivity should design using Panasonic's Bluetooth modules.
  • The EZ430-RF256x SDK license requires that the MSP430BT5190 must be used only in combination with TI Bluetooth solutions such as the CC256x for end product production.

Reference Schematic


The target board features an MSP430F5438A and most of its pins are routed out. Please refer to the PAN1323ETU Design Guide for more information.

uEVM connector

This connector is present on the backside of the target board and provides access to more pins of the MSP430BT5190 on board.
The footprint of the connector can be populated with a DF40C-40DS-0.4V connector, readily available at  distributors such as Digikey and Mouser.
The connector's functionality is as follows:
