Module Description

The CC256x QFN EM board is the development environment for the CC256x family and plugs directly into Texas

Instruments MSP430 and Stellaris experimenter boards with the added benefit of header connectors that simplify

prototype wiring and field trials. This family is based upon Texas Instrument’s CC256x integrated circuits and uses a Host Controller Interface (HCI),

a cost effective and flexible means to implement a Bluetooth network. HCI reduces BOM cost by eliminating

redundant processing capacity and giving designers the flexibility to work with a controller of their choosing, as the

Bluetooth stack resides and executes on the application

’s host processor.

The CC256x QFN EM board is intended for evaluation purpose and works with Texas Instrument’s Hardware

Development Kit. Please refer to

To aid in the implementation of this reference design, schematic and layout files are available on the CC256x Main

Wiki page.

CC256x QFN EM User Guide

Measuring Current Consumption

These jumpers can also be used to measure the current consumption by placing current sense resistors on R10 for

VBAT_CC and R7 for VDD_1V8. Both these resistors are 0.10 Ohm, 1/4 W. VBAT_CC jumper can be used to to

measure the voltage/power consumed by the CC256x including RF TX/RX while VDD_IO jumper can be used to

measure voltage/power consumed by the digital I/O's.

Antenna/U.FL Selector

The board can be configured to route the RF output from the CC256x to the on board copper antenna or the on board

U.FL connector. This configuration is done by placing the resistor in either R29 or R30 position which has negligible

resistance of a 0 Ohm. R30 will connect the RF to the U.FL while R29 will connect to the copper antenna. The U.FL

connector is used for conducted testing of the RF. The Bluetooth Hardware Evaluation Tool (BHET)

[2]

to test basic RF functionality on this board.

RF Connectors

The RF1 and RF2 connectors can be used to mount on a wide variety of TI MCU platforms such as MSP430 and

Stellaris. Note that the RF I/O's are all at 3.3V levels. This enables seamless integration of the host using TI's

platforms that comes preinstalled with EM headers. The standard pinout is described in the following table:

Clock Inputs

• The slow clock can come from 2 sources, internal and external to the board. The CC256x QFN EM gives option

to place the slow clock on the board itself or source it from an external source. It is connected to the

SLOW_CLK_IN and can be a digital signal in the range of 0-1.8 V.

• The slow clock's frequency accuracy must be 32.768 kHz, 250 ppm for Bluetooth usage (according to the

Bluetooth specification).

• When the MSP430 Experimenter board is connected, the signal is exposed from the µController. So within this

application there is no additional clock needed.
