Block Diagram BC865RPA is a Class 2 Bluetooth sub-system using BC8645 ROM chipset from leading Bluetooth chipset supplier Cambridge Silicon Radio. .It interfaces to a 64Kbit serial EEPROM. The software stack running on the BC8645 ROM chipset is fully compliant to Bluetooth Specification v4.0. BC865RPA also has necessary matching 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 BC865RPA module with PIOs running at 1.8v. Double click on the diagram to see the detail drawings. Power supply The whole module shall be powered by a single cell 3.7v Li-ion rechargeable battery (VBAT, pin#34). A coupling capacitor of 2.2uF should be placed as close to this pin as possible. The module will output 1.8v at VPAD (pin #9). All PIO pins, 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. UART Port BC865RPA has a standard UART serial interface that provides a simple mechanism for communicating with other serial devices using the RS232 protocol. A typical application will be connecting to an external HCI host. When BC865RPA 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 by configuration of the BC8645 ROM chip. 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 Minimum 1200 baud (≤2%Error) Baud rate 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 configure the ROM firmware inside BC8645 chip. 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 will run at 1.8v power rail. Mic Inputs The microphone bias, MIC_BIAS, provides power to external mic circuitry, and is configurable from 1.8v to 2.4v. 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 BC865RPA 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 PIO17 REV Select previous song, fast rewind. 29 PIO21 FWD Select next song, fast forward 14 PIO18 PLAY_PAUSE Play / pause toggle 18 PIO20 VOL- Volume decrease 15 PIO19 VOL+ Volume decrease 33 VBAT_SENSE BAT_SENSE Battery level detection 39 VREG VREG_EN Power on, sleep mode Battery and Charging The whole circuit is running with single cell 3.7v Li-ion battery connecting to the VBAT terminal. VBAT_SENSE is shorted to this terminal for battery level detection. 5V charging input coming from the micro USB port is connected to the VCHG terminal. In this typical circuit, a maximum of 150mA charging current can be supported. Note that a decoupling capacitor of 2.2uF should be connected to VCHG. 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.

At least 20cm separation distance between the antenna and the user’s body must be maintained at all times. And must not transmit simultaneously with any other antenna or transmitter, except in accordance with FCC multi transmitter product procedures. 2. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed 0dBi in the 2.4G band. 3.
