certification requirements of a minimum of 1uF, and a maximum of 10 μF being present on VCHG (VBUS). The VCHG input of HSBT3031-08 is tolerant of a constant 6.5 V and transients up to 7.0 V. If extra overvoltage protection is required, external clamping protection devices can be used. 7.1.2 USB charger detection HSBT3031-08 supports charger detection to the USB BCv1.2 standard.
100 nF decoupling capacitor may be beneficial. The VDD_PADS of a particular pin should be powered before voltages are applied to any PIO powered by that domain, otherwise back powering can occur through the electrostatic discharge (ESD) protection in the pad. PIO can be programmed to have a pull-up or pull down with two strengths (weak and strong). PIO can also be programmed with a sticky function where they are strongly pulled to their current input state.
Transaction bridge debug access is lockable. When locked, this interface only becomes active after the correct unlock key sequence is provided. 7.4 RESET# reset The HSBT3031-08 digital reset pin (RESET#) is an active low reset signal. PIO[1] defaults to RESET# upon boot. The pin is active low and on-chip glitch filtering avoids the need to filter out any spurious noise that may cause unintended resets. The RESET# pin has a fixed strong pull-up to VDD_PADS_1, and therefore can be left unconnected.
SYS_CTRL has no internal pull resistor, and requires an external pull-down if left undriven. SYS_CTRL can be logically disconnected from the power on signal for internal regulators by software. Therefore, for example, once booted, software takes control of the internal regulators and the state of SYS_CTRL is ignored by the regulators. 7.6 7.6.1 LED Drivers LED pads HSBT3031-08 contains LED pads that are configurable in four different operating modes: 1.
7.7 Audio interfaces ■ 24‑bit I²S interface with 1 input and 3 output channels ■ Programmable audio master clock (MCLK). ■ Sony/Philips digital interface (SPDIF): 2, configurable as input or output ■ Stereo analog Class-AB headphone outputs: □ Class-AB signal-to-noise ratio (SNR): ≥75dB. □ Class-AB total harmonic distortion plus noise (THD +N): ≤0.1%. ■ Dual analog inputs configurable as single ended line inputs or, unbalanced or balanced analog microphone inputs: □ SNR single-ended: ≥75dB.
8 Battery Charger The HSBT3031-08 Li-ion charger is designed to support small to large batteries (several Amp hours). It is connectable in one of two modes: ■ Internal configuration: Supporting charge rates of 2 mA to 200 mA with no external components required. ■ External configuration: Supporting charge rates of 200 mA to 1800 mA with the addition of one PNP pass device and external resistor. The charger system has five main operating states.
Figure 8-1 Charge cycle states Trickle charge This mode is entered when VBAT is sensed in the range 0 to Vpre. This is encountered only with a deeply discharged battery (below Vpre threshold, point (A)), or when the cell's battery protection circuit has opened, temporarily disconnecting the cell. It is used to pass a small charging current to safely charge a cell, and also cause a cell battery protection circuit to reset. The hysteresis on Trickle charge into Pre-Charge is typically 100 mV.
Fast charge Fast charge has two parts: ■ Constant current: Entered when VBAT is sensed in the range Vfast to Vfloat point (C). This is the maximum charge rate, and should be set according to the battery manufacturers Data Sheet. ■ Constant voltage: When Vfloat is reached the cell voltage is maintained at Vfloat, and the current slowly reduces until the termination point (E) is reached where charging ceases, and the charger transitions to Standby mode. Vfloat can be configured from 3.65 V to 4.
9 Power supply The system have three power supply mode: Mode1: Single 3.3V only supply (3.3V I/O) For improving the noise, recommend adding one 10Uf capacitor on the power supply pin Mode2. VBAT only supply (1.8V I/O). For improving the noise, recommend adding one 10Uf capacitor on the power supply pin HSBT3031-08 module_datasheet 20 Version2.0– Jun. 15th HANSONG ( NANJING) TECHNOLOGY CO.
Mode3. VBAT and 3.3V both supply (3.3V I/O). For improving the noise, recommend adding one 10Uf capacitor on the power supply pin HSBT3031-08 module_datasheet 21 Version2.0– Jun. 15th HANSONG ( NANJING) TECHNOLOGY CO.

11 Layout Notes A. If there is battery, metal, LCD, loudspeaker, etc. beside the module antenna, it is required to be at least 15mm away from the antenna B. It is recommended to use star routing for the power supply line during layout, and ensure that the power supply linearity of Bluetooth module is good, and the ground of BT is also available It must be separated from the ground of operational amplifier, power amplifier, MCU, etc., and there shall be no other interference ground under BT C.
