PAC5532EVK1 Evaluation Kit
Qorvo's PAC5532EVK1 Evaluation Kit (EVK) is a complete hardware solution enabling users to evaluate and develop motor control applications around this powerful and versatile Arm® Cortex®–M4F based micro-controller. The module contains the PAC5532 Power Application Controller (MCU), MOSFET inverter and debugging headers for serial interfaces and GPIO signals that may be used for debugging and evaluation.
Supporting Evaluation Tools
The ET-UARTSWD adapter is the preferred adapter for evaluation of PAC devices/firmware and combines a USB to UART adapter with SWD debugger connector adaptation into a single board with isolation. The ET-UARTISO-1 adapter provides only the USB to UART adapter with isolation for Qorvo application GUI communications.
ET-UARTSWD
The ET-UARTSWD isolated communications and debugging interface unifies two modules into one. Previously, interfacing a PC Computer to any of Qorvo's PAC5xxx Evaluation Modules required one module to enable UART based serial communications and a second module to allow for in-system debugging and FLASH memory programing.

ET-UARTISO-1
The ET-UARTISO-1 adapter is a USB to UART adapter for Qorvo application GUI communications with the PAC device UART, and can be used for evaluation and debugging of PAC applications.
PAC5xxx Flash Programmer Tools
Qorvo has partnered with Flash Programmer solution providers to support our Intelligent Motor Control PAC product families. These proven tools are suitable for emerging and high volume product manufacturing. Both package level (socketed) and board level Flash programming solutions are available.
Qorvo will support other vendors familiar with Arm® Serial Wire Debug (SWD) protocol to add PAC product compatibility on their existing Flash programmer platforms. For details, please contact Qorvo Sales.
