The PAC5253 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 PAC5253 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

ET-COLINK-1

The ET-COLINK-1 adapter allows the user to program and perform source level debugging of the target device using SWD from a PC. This adapter is required when using the CooCox CoIDE for development. This IDE and adapter will allow the user to program FLASH on the device, as well as perform source-level debugging of the application.

ET-UARTISO-1

The ET-UARTISO-1 adapter allows the user to connect the graphical user interface (GUI) to the target board via USB. The adapter allows the user to access the UART serial channel on the PAC device, so that the GUI may be used for evaluation and debugging of an operating system.

PAC52xx BLDC Application Firmware
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.

PAC52xx FOC Application Firmware
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.
