The USB interface on HSBT5151 acts as a USB peripheral, responding to requests from a master host controller. HSBT5151 contains internal USB termination resistors and requires no external resistors. HSBT5151 supports the Universal Serial Bus Specification, Revision v2.0 (USB v2.0 Specification), supports USB standard charger detection, and fully supports the USB Battery Charging Specification v1.2. As well as describing USB basics and architecture, the application note describes: Power distribution for high and low bus-powered configurations Power distribution for self-powered configuration, which includes USB VBUS monitoring USB enumeration Electrical design guidelines for the power supply and data lines, as well as PCB tracks and the effects of ferrite beads USB suspend support HSBT5151 module_ Product Specification 7 Version2.0 Jul. 13th HANSONG ( NANJING) TECHNOLOGY CO.,LTD Battery charging from USB, which describes dead battery provision, charge currents, charging in suspend modes, and USB VBUS voltage consideration USB termination when interface is not in use Internal modules, certification, and non-specification compliant operation 2.2 UART Interface HSBT5151 has a UART serial interface that provides a simple mechanism for communicating with other serial devices using the RS232 protocol, including for test and debug. The UART interface is multiplexed with PIOs and other functions, and hardware flow control is optional. When HSBT5151 is connected to another digital device, UART_RX and UART_TX transfer data between the 2 devices. The remaining 2 signals, UART_CTS and UART_RTS, implement optional RS232 hardware flow control where both are active low indicators. UART configuration parameters, such as baud rate and packet format, are set using the HSBT5151 firmware. 2.3 SPI Interface HSBT5151 provides a debug SPI interface for programming, configuring (PS Keys) and debugging the HSBT5151. Access to this interface is required in production. Ensure the 4 SPI signals and the SPI/PCM# line are brought out to either test points or a header. To use the SPI interface, the SPI/PCM# line requires the option of being pulled high externally. HSBT5151 module_ Product Specification 8 Version2.0 Jul. 13th HANSONG ( NANJING) TECHNOLOGY CO.,LTD Noted:Pin to Pin distance is 1.27mm 2.4 I2C Interface The HSBT5151 supports an I2C interface for I/O port expansion. The default assignment of the I2C interface onto the PIOs on the HSBT5151 is: PIO[0] is the I2C interface SCL line (AMP_I2C_SCL) PIO[1] is the I2C interface SDA line (AMP_I2C_SDA) Alternatively, the I2C interface can be assigned to two PIOs from PIO[9:0] using PSKEY_I2C_SCL_PIO and PSKEY_I2C_SDA_PIO. NOTE The I2C interface requires external pull-up resistors. Ensure that external pull-up resistors are suitably sized for the I2C interface speed and PCB track capacitance. 2.5 LED Drivers HSBT5151 includes a 3-pad PWM LED driver for driving RGB LEDs for producing a wide range of colors. All LEDs are controlled by application. The terminals are open-drain outputs, so the LED must be connected from a positive supply HSBT5151 module_ Product Specification 9 Version2.0 Jul. 13th HANSONG ( NANJING) TECHNOLOGY CO.,LTD rail to the pad in series with a current-limiting resistor. Figure 7-1 LED equivalent circuit From Figure 7-1 it is possible to derive Equation 7-1 to calculate ILED. If a known value of current is required through the LED to give a specific luminous intensity, then the value of RLED is calculated. Equation 7-1 LED current NOTE The supply domain for LED[2:0], VDD_PADS_2, or VDD_PADS_1, must remain powered for LED functions to operate. 2.6 Audio interfaces Dual I²S outputs I²S input, SPDIF input (uncompressed PCM only) USB audio Stereo audio ADC with line input, stereo audio DAC Supported sample rates of 8, 11.025, 16, 22.05, 32, 44.1, and 48kHz 2.7 Reset HSBT5151 is reset from several sources: RST# pin HSBT5151 module_ Product Specification 10 Version2.0 Jul. 13th HANSONG ( NANJING) TECHNOLOGY CO.,LTD Power-on reset USB charger attach reset Software configured watchdog timer The RST# pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. Recommends applying RST# for a period >5ms. At reset the digital I/O pins are set to inputs for bidirectional pins and outputs are set to tristate. 2.8 Automatic Reset Protection HSBT5151 includes an automatic reset protection circuit that restarts the HSBT5151 when an unexpected reset occurs, for example, ESD strike or lowering of RST#. This reset protection circuit automatically restarts the HSBT5151 and enables the application to restore previous operation. NOTE If RST# is held low for > 2.4 s and VCHG is not applied, HSBT5151 turns off. A rising edge on VREGENABLE or VCHG is then required to power on HSBT5151. 3 Battery Charger The battery charger hardware is controlled by the on-chip application. The battery charger has 5 modes: Disabled HSBT5151 module_ Product Specification 11 Version2.0 Jul. 13th HANSONG ( NANJING) TECHNOLOGY CO.,LTD Trickle charge Fast charge Standby: fully charged or float charge Error: charging input voltage, VCHG, is too low Transitions between the trickle charge, fast charge and standby modes are triggered by changes in battery voltage and charger current. Table 10-1 Battery charger operating modes determined by battery voltage and charger current Figure 10-1 shows the mode-to-mode transition voltages. Figure 10-1 Battery charger mode-to-mode transition diagram 4 Power supply The system have two power supply mode: HSBT5151 module_ Product Specification 12 Version2.0 Jul. 13th HANSONG ( NANJING) TECHNOLOGY CO.,LTD Mode1: Single 3.3V only supply. For improving the noise, recommend adding one 220Uf capacitor on the power supply pin If the HSBT5151 is powered with an external 3.3 V supply connected to the VBAT line, Power_EN must be driven high after the IC has powered up otherwise the device may not initialise properly. Mode2. Single 5V only supply. A USB dongle is only powered when it is plugged into a USB port and does not need a switch to control the power. POWER_EN should be left unconnected as the USB supply connected to the VCHG input will enable the IC correctly.
