Note:
The reset protection is cleared after typically 2s (1.6s min to 2.4s max).
If RST# is held low for >2.4s FSC-BT806BB turns off.
A rising edge on VREGENABLE or VCC_CHG is requiredto power on FSC-BT806BB.
4.3 General Purpose Analog IO
FSC-BT806B has 1 general-purpose analogue interface pins, AIO1, for accessing internal circuitry and controlsignals.
Auxiliary functions available on the analogue interface include a 10-bit ADC and a 10-bit DAC. Signalsselectable on this
interface include the band gap reference voltage. When configured for analogue signals the voltagerange is
constrained by the analogue supply voltage. When configured to drive out digital level signals generatedfrom within
the analogue part of the device, the output voltage level is determined by VDD_AUX(internal).
4.4 General Purpose Digital IO
10 lines of programmable bidirectional I/O are available on the FSC-BT806B. Some of the PIOs on the FSC-BT806B have
alternative functions:
3 digital microphone interfaces for control of up to 3 digital microphones:
 Clock on any even PIOs as determined by the software
 Data on any odd PIOs as determined by the software
I²C interface on any PIOs as determined by the software
LED[2:0] directly map to PO[31:29]
I2S/PCM interface on PIO[20:17]
4.5 RF Interface
For this module, the antenna must be connected to work properly.
The user can connect a 50ohm antenna directly to the RF port.
2402–2480 MHz Bluetooth 5.0 Dual Mode (BT and BLE); 1 Mbps to 3 Mbps over the air data rate.
TX output power of +10dBm(MAX).
Receiverto achieve maximum sensitivity -88dBm @ 1 Mbps BLE or Classic BT, 2 Mbps, 3 Mbps).
4.6 Serial Interfaces
4.6.1 UART Interface
FSC-BT806Bprovides one channels of Universal Asynchronous Receiver/Transmitters(UART)(Full-duplex asynchronous
communications). The UART Controller performs a serial-to-parallel conversion on data received from the peripheral
and a parallel-to-serial conversion on data transmitted from the CPU. Each UART Controller channel supports ten types
of interrupts.
