PAC55712EVK1 Evaluation Kit
Qorvo's PAC55712EVK1 development platform is a complete hardware solution enabling users, not only to evaluate the PAC55712 device, but also develop power applications revolving around this powerful and versatile ARM® Cortex®-M4F based micro-controller. The module contains a PAC55712 Power Application Controller (MCU) and its internal peripherals, including new features such as Cycle By Cycle PWM truncation, AIO7/8/9 Sample And Hold, Windowed Watchdog Timer, enhanced gate drive strength, as well as enhanced low Hibernate current.
To aid in the application development the PAC55712EVK1 offers access to each and every one of the PAC55712 device's signals by means of a series of female header connectors.
The PAC55712EVK1 can be used with various Graphical User Interface (GUI) software suites to externally control particular application features over the PAC55712 UART interface. Provided with the development platform, the ET-UARTSWD module adds fully isolated USB to UART Virtual COMM Port, as well as access to the PAC55712’s SWD port through a fully isolated bidirectional channel which allows most SWD program/debug modules to interconnect with the system.
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.
