The PAC5220 belongs to Active-Semi’s broad portfolio of full-featured Power Application Controller® (PAC) products that are highly optimized for controlling and powering next generation smart energy appliances, devices, and equipment. These application controllers integrate a 50MHz Arm® Cortex®-M0 32-bit microcontroller core with Active-Semi’s proprietary and patent-pending Multi-Mode Power ManagerTM, Configurable Analog Front EndTM, and Application Specific Power DriversTM to form the most compact microcontroller-based power and general purpose application systems. The PAC5220 microcontroller features up to 32kB of embedded FLASH and 8kB of SRAM memory, a high-speed 10-bit 1µs analog-to-digital converter (ADC) with dual auto-sampling sequencers, 5V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.

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 Active-Semi 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 Active-Semi’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. | |

PAC5xxx Flash Programmer Tools
Active-Semi 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.
Active-Semi will support other vendors familiar with Arm® Serial Wire Debug (SWD) protocol to add PAC product compatibility on their existing Flash programmer platforms.

Installer for the PAC52XX BLDC application firmware, which implements sensored BLDC and sensorless BEMF motor control on all members of the PAC52XX family. The installer contains example application source code, Windows graphical user interface (GUI), and documentation to allow the user to configure the system to work with their target motor. Project files for IAR Systems Embedded Workbench for ARM (EWARM) and Keil uVision are included.
Installer for the PAC FOC application firmware designed to show case motor control using sensorless Field Oriented Control (FOC) on all PAC devices. The installer contains example FOC application source code, Windows graphical user interface (GUI), and documentation to allow the user to configure the system to work with their target motor. Project files for IAR Systems Embedded Workbench for Arm® (EWARM), Keil uVision and Eclipse are included. The FOC application provides a configurable set of features to meet many different application requirements such as sensorless position/speed estimator, start-in-motion (SIM), three or single shunt operation, open phase detection (OPD), field weakening and others.
Installer for the PAC52XX Software Development Kit (SDK) that provides register level definitions and peripheral driver APIs for developing ARM M0 application firmware on all PAC52XX devices. The PAC52XX SDK is a unified SDK that supports Keil µVision IDE, IAR Systems Embedded Workbench for ARM (EWARM) IDE, and GCC tool chains.
Installer for the PAC52xx Example Code that provides a simple source code example for getting started with the following IDE projects: Keil MDK (µVision), IAR Systems Embedded Workbench for ARM (EWARM), and Eclipse.
PAC52xx IDE Support
Development of application firmware for PAC52XX Arm® Cortex® M0 is made easy with standard integrated development environments (IDEs). Several of the most popular IDEs contain support for PAC52XX devices including Keil uVision, and IAR Systems Embedded Workbench for Arm®. Eclipse development is possible using J-Link by downloading and installing the “Eclipse with PAC support” package.
