Qorvo's PAC5256 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.
PAC5256 is optimized for AC-powered BLDC or PMSM motor control applications such as AC-powered fans, white goods or compressors. PAC5256 also includes optimized hardware support and software libraries for the IEC/UL 60730 Class B Safety standard.
PAC5256 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 10-bit 1 MSPS dual auto-sequencer ADC, PWM timers with hardware dead-time insertion, etc. The product contains an integrated N-CH Buck DC/DC controller, a 5V / 200mA converter and multiple LDOs for system and power management components for he 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.

Qorvo's PAC5256EVK1 development platform is a complete hardware solution enabling users not only to evaluate the PAC5256 device, but also develop power applications revolving around this powerful and versatile Arm® Cortex®-M0 based microcontroller. The module contains a PAC5256 Power Application Controller® MCU, and all the necessary circuitry to properly energize the MCU and its internal peripherals once power is applied.
To aid in the application development, the PAC5256EVK1 offers access to each and every one of the PAC5256 device's signals by means of a series of male header connectors.
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.
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.
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.
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.
