2, when the No. 39 PIN (VCC_CHG) with a 5V input pin,
this pin outputs 3.2V ~ 3.4V (maximum current: 250mA)
Note 8
Analog input voltage range: 0~ 1.3V
Note 9
By default, this PIN is an empty feet. This PIN can connect to an external antenna to improve the Bluetooth
signal coverage.
If you need to use an external antenna, by modifying the module on the 0R resistance to block out the
on-board antenna; Or contact Feasycom for modification.
Note 10
Note: IO ports are 1.7~3.7V level (for example: SPI, UART, PIO, I2S)
4. PHYSICAL INTERFACE
4.1 Power Management
4.1.1 Power Supply
The transient response of the regulator is important. If the power rails of the module are supplied from an
external voltage source, the transient response of any regulator used should be 20μs or less. It is essential that the
power rail recovers quickly.
4.1.2 Battery Charger
4.1.2.1 Battery Charger Hardware Operating Modes
The default mode for the FSC-BT1006A battery charger is OFF.
The internal charger circuit can provide up to 200mA of charge current.
The battery charger hardware is controlled by the on-chip application.The battery charger has 5 modes:
Disabled
Trickle charge
Fast charge
Standby: fully charged or float charge
Error: charging input voltage, VCHG, is too low
The battery charger operating mode is determined by the battery voltage and current, see the table below and the
picture below.
