CC256xEM Bluetooth Adapter Kit User Guide
The CC256xEM Bluetooth®Adapter Kit (CC256XEM-STADAPT) is a connector board aimed to help
evaluate TI’s CC256x Bluetooth and Dual-Mode solution with STM32 MCUs. The CC256XEM-STADAPT
board serves as a translation board between a CC256xEM board (CC256XQFNEM, CC2564MODAEM,
and CC2564MODNEM) and a STM32 MCU Evaluation board (STM3240G-EVAL and
STM32F4DISCOVERY).
This document provides an overview of the CC256XEM-STADAPT board, and describes the required
hardware and software tools. Furthermore, this user's guide details the functions of each component on
the board and how they are configured for different settings. There is also a Bluetooth Adapter Kit Quick
Start Guide (SWRU416) that summarizes the configurations for different functions. There are also design
files available with schematics, layouts, and bill of materials (SWRC308).

Chapter 1
SWRU417–June 2015
Overview
The CC256XEM-STADAPT board allows the connection between a CC256xEM board (CC256XQFNEM,
CC2564MODAEM, and CC2564MODNEM) and a STM32 MCU Evaluation board (STM3240G-EVAL and
STM32F4DISCOVERY).
On one side, the JR1 and JR2 connectors are provided to interface with a CC256xEM board; on the other
side, there are two options for the STM32 MCU Evaluation boards. For the first option, JE3 and JD2
connectors enable the connection to CN3 and CN4 headers in the STM3240G-EVAL board, respectively.
In the second option, JD1 and JD2 connectors allow the connection to headers P1 and P2 in the
STM32F4DISCOVERY board, respectively. Furthermore, an on-board 32.768-KHz crystal oscillator can
provide the slow clock to the CC256xEM boards.
The CC256XEM-STADAPT board provides flexibility to route the UART and PCM/I2S signals to different
pins on the STM32 MCU Evaluation boards through a set of resistors and jumpers. The jumpers on
headers J1 through J6 control which evaluation board, STM3240G-EVAL or STM32F4DISCOVERY,
receives the UART signal. Zero-ohm resistors can be soldered on to the PCM/I2S section to provide the
signal to the STM32 MCU Evaluation boards if their application requires I2S communication. Reference
Section 2.3 and Section 2.4 for the UART and PCM/I2S communication configurations.

UART Selection
www.ti.com
2.3 UART Selection
The headers J1 through J6 have associated jumpers that connect two adjacent pins, such as pin 1 to 2 or
pin 2 to 3. This is to direct the UART signals from the CC256X EM to the desired STM32 board. Thus,
when the CC256XEM-STADAPT is mounted on the STM3240G-EVAL, all 6 jumpers should be connecting
pins 1 and 2. When mounted on the STM32F4DISCOVERY, the jumpers should be connecting pins 2 and
3.

There are only two configurations – STM32F4DISCOVERY USART3 and STM3240G-EVAL USART6 –
necessary to run all of the demo programs that only require UART communication. In all of these, the
resistors R61, R71, R81, and R91 are always connected, while R60, R70, R80, and R90 are not.
However, the STM3240G-EVAL board provides the option of using UART5 for digital communication
instead of USART6. For these applications, the connections for the resistors must be swapped.

PCM/I2S Selection
2.4 PCM/I2S Selection
Several empty resistor pads are available for configuration. Zero-ohm resistors can be soldered onto them
to complete the connections, which are necessary for applications that require I2S communication. These
include A3DPDemo_SNK and HFPAGDemo (see Section 5, Settings, of the Quick Start Guide,
SWRU416, for the full list).
There are four different configurations – two per board – that can be used to run all of the demo programs.
R31, R41, or R43 are not populated in any of these configurations. However, for other applications that
might require connection of other signals such as EVAL_I2S2ext_SDPI2, the user may make these
connections.
2.5 32.768-KHz Clock
Next to the CC256X EM connectors is a 32.768-KHz crystal oscillator circuit. This provides the slow clock
for the CC256X EM.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
