    PAC52422EVK1 Evaluation Kit

    PAC52422EVK1-1

    Qorvo's PAC52422EVK1 development platform is a complete hardware solution enabling users not only to evaluate the PAC52422 device, but also develop power applications revolving around this powerful and versatile ARM® Cortex®-M0 based micro-controller. The module contains a PAC52422 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 PAC52422EVK1 offers access to each and every one of the PAC52422 device's signals by means of a series of female header connectors.

    The PAC52422EVK1 can be used with various Graphical User Interface (GUI) software suites to externally control particular application features over the PAC52422 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 PAC52422’s SWD port through a fully isolated bidirectional channel which allows most SWD program/debug modules to interconnect with the system.

    Supporting Evaluation Tools

    ET-UARTSWD

    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.

    RD5223PT Battery Operated Power Tool Reference Design

    RD5223PT

    The EP5223PT1-1 reference design shows how the PAC5223 can be used to implement a high-current power tool application such as a battery-operated drill in a compact form-factor. This design is a 2.5cmx6cm PCB that can support up to 25A RMS and a peak current of 200W to 300W with the proper heat-sinking. Since the PAC5223 provides just the controller function, by selecting different FETs and component values, the power output of this design could be increased to much higher levels for different application requirements.
