PAC52723EVK1 Evaluation Kit
Qorvo’s PAC52723EVK1 development platform is a complete hardware solution enabling users, not only to evaluate the PAC52723 device, but also develop power applications revolving around this powerful and versatile ARM® Cortex®-M0 based micro-controller. The module contains a PAC52723 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 PAC52723EVK1 offers access to each and every one of the PAC52723 device’s signals by means of a series of female header connectors.
The PAC52723EVK1 can be used with various Graphical User Interface (GUI) software suites to externally control particular application features over the PAC52723 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 PAC52723’s SWD port through a fully isolated bidirectional channel which allows most SWD program/debug modules to interconnect with the system.
