The software stack running on the BlueCore5 MM Ext chipset is fully compliant to Bluetooth Specification v2.1 + EDR. BC5MMRPB(C) also has necessary balun and bandpass filters to interface with a build-in PCB antenna, which forms a very cost effective radio subsystem. Applications Example The above schematic shows a typical application of BC5MMFPB (C) module. Double click on the diagram to see the detail drawings. Power supply The whole module shall be supplied with a clean 3.3v at its 3V3 power port (pin #9). A coupling capacitor should be placed as close to this pin as possible. All others PIO pins (including VREG), SPI programming port and UART port will run at this power rail. Differential Audio Outputs The output stage digital circuitry converts the signal from 16-bit per sample, linear PCM of variable sampling frequency to bit stream, which is fed into the analogue output circuitry. The output stage circuit comprises a DAC with gain setting and class AB output stage amplifier. The output is available as a differential signal between SPK_LN and SPK_LP for the left channel, as the schematic shows, and between SPK_RN and SPK_RP for the right channel. The output stage is capable of driving a speaker directly when its impedance is at least 8Ω. PCM Interface (BC5MMFPC only) The audio PCM interface supports continuous transmission and reception of PCM encoded audio data over Bluetooth. PCM is a standard method used to digitise audio, particularly voice, for transmission over digital communication channels. Through ts PCM interface, BlueCore5‑Multimedia External has hardware support for continual transmission and reception of PCM data, so reducing processor overhead. BlueCore5‑Multimedia External offers a bidirectional digital audio interface that routes directly into the baseband layer of the on-chip firmware. It does not pass through the HCI protocol layer. Hardware on BlueCore5‑Multimedia External allows the data to be sent to and received from a SCO connection. Up to 3 SCO connections can be supported by the PCM interface at any one time. BlueCore5‑Multimedia External can operate as the PCM interface master generating PCM_SYNC and PCM_CLK or as a PCM interface slave accepting externally generated PCM_SYNC and PCM_CLK. BlueCore5‑Multimedia External is compatible with various clock formats, including Long Frame Sync, Short Frame Sync and GCI timing environments. Host Information This module was defined to be used for specific host only. The designated host for this module was: Company: GT-tronics HK Ltd. Address: B202, Tonic Industrial Center, 19 Lam Hing Street, Kowloon Bay, Hong Kong Host Model Name: BTSPK Host brand name: GT-tronics UART Port BC5MMFPB (C) has a standard UART serial interface that provides a simple mechanism for communicating with other serial devices using the RS232 protocol. When BC5MMFPB (C) is connected to another digital device, RX and TX transfer data between the 2 devices. UART configuration parameters, such as baud rate and packet format, are set using BlueCore5‑Multimedia External firmware. To communicate with the UART at its maximum data rate using a standard PC, an accelerated serial port adapter card is required for the PC. Possible UART Settings Parameter Possible values Baud rate Minimum 1200 baud (≤2%Error) Maximum 9600 baud (≤1%Error) Parity None, Odd or Even Number of stop bits 1 or 2 Bits per byte 8 SPI Programming Port The SPI is used to program and configuration, and debug the BlueCore5‑Multimedia External. It is required in production. Ensure the 4 SPI signals are brought out to either test points or a header. Note that these four signals are run at 3.3v power rail. Mic Inputs The microphone bias, MIC_BIAS, derives its power from the 3V3 power port and requires a 4.7μF capacitor on its output. The MIC_BIAS is like any voltage regulator and requires a minimum load to maintain regulation. The MIC_BIAS maintains regulation within the limits 0.200mA to 1.230mA. The input impedance at MIC_A_N, MIC_A_P, MIC_B_N and MIC_B_P is typically 6.0kΩ . LED Drivers BC5MMFPB (C) includes 2 pads dedicated to driving LED indicators. Both terminals can be controlled by firmware, The terminals are open-drain outputs, so the LED must be connected from a positive supply rail to the pad in series with a current limiting resistor. It is recommended that the LED pad, LED[0] or LED[1] pins, operate with a pad voltage below 0.5V. In this case, the pad is like a resistor, RON . The resistance together with the external series resistor sets the current in the LED. Buttons The example application has assigned the following functions to each PIO pins: PIN NAME Function Descriptions 13 PIO14 REV Select previous song, fast rewind. 32 PIO12 FWD Select next song, fast forward 33 PIO11 PLAY_PAUSE Play / …

COVER LETTER The BC5MMFPX Module has been granted as Limited modular approval for portable applications. Integrators may use the BC5MMFPXModule in their final products without additional FCC certification if they meet the following conditions. Otherwise, additional FCC approvals must be obtained. 1.To comply with FCC regulations limiting both maximum RF output power and human exposure toRF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed 0dBi in the 2.4G band. 2.The BC5MMFPX Module and its antenna must not be co-located or operating in conjunction with any other transmitter orantenna within a host device. 3.A label must be affixed to the outside of the end product into which the BC5MMFPX Module is incorporated, with a statement similar to the following: This device contains FCC ID: B4OBC5MMFPX. 4.A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. 5. OEM integrators and end-users must be provided with transmitter operation conditions for satisfying RF exposure compliance. 6. This device is sold to OEM integrators and the OEM integrators are instructed to ensure that the end user has no manual instructions to remove or install the device. The end product with an embedded BC5MMFPX Module may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. Thank you for your attention to this matter. Yours Sincerely, Dennis Wong Admin Asst
