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.

Hardware Description
The CC256XEM-STADAPT routes the pins from a CC256XEM board to the appropriate pins of either a
STM3240G-EVAL or STM32F4DISCOVERY board. It also has a 32.768 KHz crystal oscillator to provide
the slow clock to the CC256XEM.

2.2 STM32 Connectors
The CC256XEM-STADAPT board interfaces with either a STM3240G-EVAL or STM32F4DISCOVERY
through use of three 2×50 headers: JD1, JD2, and JE3.
NOTE: There may be alternate functions for each MCU pin, but only the ones used in the relevant
setting are listed.
2.2.1 JD1 Headers
The JD1 headers are one of three 2×50 headers that protrude out of the bottom of the board. The
CC256XEM-STADAPT can connect to a STM32F4DISCOVERY Evaluation board by connecting JD1 and
JD2 into the P1 and P2 headers, respectively.

2.2.2 JD2 Headers
The JD2 headers are among the three 2×25 headers on the bottom of the board. These headers are used
when connecting to either the STM32F4DISCOVERY or STM3240G-EVAL. When connecting to the
DISCOVERY board, the JD1 and JD2 connect to the P1 and P2 headers, respectively. When connecting
to the EVAL board, the JE3 and JD2 connect to the CN3 and CN4 headers, respectively.

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.

www.ti.com 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.
