    Qorvo's PAC5225 belongs to Qorvo's Power Application Controller® (PAC) product family. This family features highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC.

    The product integrates a FLASH-based MCU, power management, high-side and low-side gate drivers and signal conditioning components in a single product.

    PAC5225 is optimized for battery-powered BLDC motor control applications up to 48V that implement IEC/UL60730 Class B Safety.

    PAC5225 contains a 50MHz Arm® Cortex®-M0 with 32kB of FLASH that can be used to implement high-performance motor control and supervisory applications. The MCU also contains motor control peripherals such as 10b 1MSPS dual auto-sequencer ADC, PWM timers with hardware dead-time insertion, etc. The Multi-Mode Power Manager™ (MMPM) contains a Buck or SEPIC DC/DC controller and power management components for powering the IC and other PCB system power supplies. The Application-Specific Power Drivers™ provide integrated gate drivers for use with an external inverter. The Configurable Analog Front-End™ (CAFE) provides signal-chain components such as differential and single-end amplifiers, comparators and DACs.

    EP5223LVM1-1 Evaluation Kit

    EP5223LVM1-1

    (Note: this kit supports PAC5223 and PAC5225)

    Qorvo's EP5223LVM1-1 development platform is a complete hardware solution enabling users not only to evaluate the PAC5223 device, but also develop power applications revolving around this powerful and versatile ARM® Cortex®-M0 based mirco-controller. The module contains a PAC5223 Power Application Controller (MCU) and its internal peripherals once power is applied.

    To aid in the application development the EP5223LVM1-1 offers access to each and every one of the PAC5223 device's signals by means of a series of female header connectors.

    The EP5223LVM1-1 can be used with various Graphical User Interface (GUI) software suites to externally control particular application's features over the PAC5223 UART I/F. The ET-UARTISO-1 is a USB to UART adapter that can provide the required PC connectivity. If CooCox CoIDE or CoFlash are desired for development, the ET-COLINK-1 adapter is an inexpensive option for SWD Flash programming and debugging.

    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.

    ET-UARTISO-1

    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.
