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).

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. Figure 1-1.

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. Figure 2-2. Block Diagram of UART Connections Table 2-6.

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. 16 Hardware Description SWRU417 - June 2015 Submit Documentation Feedback Copyright (c) 2015, Texas Instruments Incorporated PCM/I2S Selection www.ti.com 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.

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.
