The PAC5225 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 PAC5225 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
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 CooCox CoIde, IAR Systems Embedded Workbench for ARM (EWARM) and Keil uVision are included.
Installer for the PAC52XX FOC application firmware designed to show case motor control using sensorless Field Oriented Control (FOC) on all members of the PAC52XX family. 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 CooCox CoIde, IAR Systems Embedded Workbench for ARM (EWARM) and Keil uVision 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), initial position detection (IPD), open phase detection (OPD), field weakening and others.
PAC52xx Software Development Kit
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.
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 integrated IDEs contain support for PAC52XX devices including Keil uVision, IAR Systems Embedded Workbench for ARM, and Coocox CoIDE.
