2 HVP-56F80748 functional description

This chapter describes the features and functions of the HVP-56F80748 board. For

details of the MC56F80748 MCU features, see MC56F80xxx Reference Manual.

2.1 Power supplies

The HVP-56F80748 board can be powered in two ways, which is shown in Section 1.4.

•Through USB-Mini-B connector J2. The 5 V input voltage (P5V_SDA) from the USB

connector powers the CP2102N (USB-to-UART bridge controller), NCP1117 (5 V to 3.3

V voltage regulator), and ADuM6201 (Isolators with integrated DC-to-DC converter).

–The converted P3V3_SDA (3.3 V) from NCP1117 shares the same ground

(GND_SDA) with USB connector. It gives power to side 1 of Si8661BD (six-channel

digital isolator) and JTAG connector.

–The converted +3.3V_ISO (3.3 V) from ADuM6201is an isolated power source which

shares the same ground (GND) with DSC 56F80748. This isolated +3.3V_ISO is

used to power the digital circuits of the DSC through diode D3 as well as side 2 of

Si8661BD.

•Through PCI Express connector J3. When the HVP-56F80748 card is plugged into a

mother board, such as HVP-MC3PH, both the digital and analog circuits inside DSC

are powered up through +3.3V and +3.3VA that come from the PCI Express connector.

Note:

•When HVP-56F80748 is not plugged into a mother board, it can only be powered

through the USB connector, and only the digital circuit inside DSC is powered up.

Therefore, the analog part (example, ADC) of the DSC would not work properly in this

case.

•When HVP-56F80748 is plugged into a mother board and the mother board is also

powered up, both the digital and analog circuits of MC56F80748 are powered up

through +3.3V and +3.3VA from J3 connector.

•HVP-56F80748 can be powered through USB connector J2 and PCI Express

connector J3 at the same time. A diode D3 is placed between +3.3V_ISO and +3.3V to

mitigate the conflict.

•Always provide power input from USB connector J2 when you want to program DSC

through JTAG connector, because pin 11 of JTAG connector comes from P3V3_SDA

which is originated from USB connector.

The table below provides power supply details of the HVP-56F80748 board.

2.2 Isolated USB-to-UART interface

The HVP-56F80748 board supports an isolated USB-to-UART function through

CP2102N and ADuM6201. CP2102N is not populated by default.

CP2102N provides a virtual COM interface between the host computer and MC56F80748

through USB port (J2) by using SCI1 on MC56F80748. It includes a USB 2.0 full-speed

function controller, USB transceiver, oscillator, and universal asynchronous receiver/

transmitter (UART) in a small package.

Note:

CP2102N device requires installing the VCP device drivers that can be downloaded from

https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads. After

the driver for CP2102N is installed, the host computer will enumerate COM ports when

the USB cable is plugged into the J2 USB port. This makes the device appear as a VCP.

You can use these ports to communicate with the processor with USB interface via a

standard PC serial emulation port (for example, Putty and Tera Term).

The following figure shows the circuit diagram of CP2102N USB-to-UART device using

SCI1 interface.

The motor control and power conversion are high voltage and high EMI applications. To

ensure the safety and reliable communication, the connection between the host computer

and the DSC is isolated. ADuM6201(U3) is used to isolate the RXD and TXD signals of

DSC from the host.

through PCI Express connector, which can also be used to realize isolated USB-to-UART

communication together with the HVP-MC3PH board.

2.3 Input/output headers

The HVP-56F80748 daughter card is compatible with the mother boards through the PCI

Express connector. The mother board can be any of the following:

•HVP-MC3PH

•Totem-Pole Bridgeless PFC Converter

•LLC Resonant Converter with Sync Rectifier

Peripheral pins of DSC such as PWM, ADC, OPAMP, and CMP are connected to the

PCI Express connector for the development of the motor control and power conversion

applications.

2.4 Isolated debug interface

The MC56F80748 processor has five GPIO pins multiplexed with the four JTAG signals

and one reset signal:

•RESETB input (default signal on GPIOD4 pin)

•TMS input (default signal on GPIOD3 pin)

•TCK input (default signal on GPIOD2 pin)

•TDO output (default signal on GPIOD1 pin)

•TDI input (default signal on GPIOD0 pin)

The GPIOD[4:0] signals are connected on the HVP-56F80748 board to the 14-pin JTAG

connector (J1) through a six-channel digital isolator SI8661BD. A standalone debug tool

is needed to program and debug HVP-56F80748 board, such as Multilink development

interface, and power P5V_SDA must be provided through USB connector J2.

The following table describes the JTAG header pinout.
