Hardware
This section provides information on various aspects of the Development Kit hardware. In addition,
Appendix A, “Board Diagram“, contains a diagram of the Development Kit board.
4.1 Signal and Connection Descriptions
The development kit contains the following connections, switches, and indicators:
• Power supply input
• Modular jack 4/4 connector for mono-audio speaker and microphone (headset application)
• RS232 interface
• UART interface
• USB interface
• Antenna connector
• JTAG allowing interface to MC71000 production test
• Reset switch
• Four control buttons for the headset application
• On/off switch
• Seven status LEDs
The power supplied for the development kit is DC with the ratings stated in the specifications.
An analog audio signal to be transmitted over the Bluetooth connection can be fed into the development kit
via the modular jack or as streaming audio through the host interface. It will be converted to digital data and
transmitted through the Bluetooth link. A digital audio signal received from a connected Bluetooth device
will be converted to an analog audio signal and available at the modular jack or as streaming audio through
the host interface (UART, SSI, SPI). The MC71000 has a Bluetooth Audio Signal Processor (BTASP) for
superior audio performance.
The RS232/UART interfaces can be used to transfer data and audio between a host and the Bluetooth device.
The firmware of the development kit can be upgraded through the RS232/UART interface.
The USB interface is a standard HCI USB interface. This interface can be used to connect the development
kit to a PC or other devices with PC-compatible USB connections.
The CODEC is attached to the MC71000 via the SPI (data) and SSI (streaming audio) interfaces.
The antenna connector is an SMA 50 ohm connection.
