Overview
Qorvo’s PAC5556AEVK2 development platform is a complete hardware solution enabling users not only to evaluate the PAC5556A device, but also develop power applications revolving around this powerful and versatile ARM® Cortex®-M4F based microcontroller. The module contains a PAC5556A Power Application Controller® (MCU) and all the necessary circuitry to properly energize the MCU and its internal peripherals once power is applied. The PAC5556AEVK2 features new GaN power switches as offered by Cambridge GaN Devices ICeGaN power transistor. ICeGaN HEMT power transistors enjoy easy-to-drive MOSFET compatible gate drive, integrated Miller Clamp, and integrated current sense function, eliminating the need for expensive and bulky, separate current sense resistors. To aid in the application development, the PAC5556AEVK2 offers access to every one of the PAC5556A device’s signals using a series of male header connectors.
The PAC5556AEVK2 also contains access to an external USB to UART module enabling users to connect the evaluation module to a PC through a conventional Virtual COM Port which can then be used in the communication efforts by taking advantage of the PAC5556A’s UART interface. Graphical User Interface (GUI) software suites can be employed to externally control particular application features. Finally, the PAC5556AEVK2 module gives access to the PAC5556A’s SWD and JTAG ports allowing users to both program the application into the device’s FLASH memory, as well as debug the application in real-time. The provided 4-pin connector is compatible with a decent variety of SWD based debugger/programmer modules, widely available. In parallel, a MIPI20 connector is made available that provides SWD, JTAG, and TRACE functionality, greatly expanding the existing debugging capabilities.

Pinout and Signal Connectivity
The following diagram shows the male header pinout for the PAC5556AEVK2 evaluation module, as seen above:
Power Input
Power to the PAC5556AEVK2 evaluation module can be applied to the J6 three-position terminal block connector. Power to the PAC5556AEVK2 evaluation module should not exceed 240 VAC (450 VDC Abs Max). The PAC5556AEVK2 is optimized to operate with voltages ranging from 110 VAC to 220 VAC Nominal. When the rectified input voltage (VM) goes above around 85 VDC, the system’s High Voltage Buck Converter is powered up and the device exits UVLO protection. At this time all subsystems, including internal voltage regulators, analog front end, and microcontroller, are enabled.
LED’s
When an operational voltage is applied, LED D2 will light up. This is the LED that notifies the VSYS (5V) rail is up and running. VP (15V gate drive), 3.3V (for analog circuitry), and 1.2V (for CPU core) regulators will also be operating at this point. The module is ready for use. The following table shows the provided LED and its associated diagnostic function.
| LED | Description |
| D2 | VSYS (5V). Light up when the PAC5556A device is successfully powered up by VM. |
SWD Debugging
Connector J1 offers access to the PAC5556A SWD port lines.
| J1 Pin | Terminal | Description |
| 1 | + | VCCIO (3.3V) |
| 2 | SD | SWD Serial Data (PF1) |
| 3 | CL | SWD Serial Clock (PF0) |
| 4 | – | GND (System Ground) |
Communications
Connector J4 offers access to the PAC5556A UART port lines.
| J4 Pin | Terminal | Description |
| 1 | + | VCCIO (default is 5V) |
| 2 | RX | MCU Receive Line (PE3) |
| 3 | TX | MCU Transmit Line (PE2) |
| 4 | – | GND (System Ground) |
Hall Sensor
Terminal Block J15 offers access to the PAC5556A resources on PORTE utilized for hall sensor-based commutation. Mimicking the same signal structure, 0.100” spacing header J5 offers quick access to the hall sensor inputs.
| J15/J5 Pin | Terminal | Description |
| 1 | + | VCCIO (3.3V) |
| 2 | Hall Sensor U | PORTE4 |
| 3 | Hall Sensor V | PORTE5 |
| 4 | Hall Sensor W | PORTE6 |
| 5 | GND | GND (System Ground) |
SET UP
The setup for the PAC5556AEVK2 evaluation module requires up to four simple connections.
- Connect the 3 Phase BLDC/PMSM motor via space tab connectors PHASE U, PHASE V, and PHASE W.
- If Serial Communications are desired, connect the USB to the UART module 4-pin connection to J4.
- For debugging/programming, connect a suitable USB SWD module to J1 by using a standard 4-wire cable.
- Connect rectified DC voltage to screw terminals VM and GND.
NOTE: Due to the high voltage nature of this board, it is highly recommended for all connections to be made before applying power. Once the rectified input voltage goes above 85VDC, the PAC5556A’s Multi-Mode Power Manager will be engaged and the VSYS (5V) regulator will be enabled. This event will result in LED D2 lighting up. - PAC5556AEVK2 Evaluation Module Connections
