PAC5523EVK1

Active-Semi’s PAC5523EVK1 evaluation kit is a complete hardware solution enabling users to evaluate the PAC5523 device, but also develop motor control applications revolving around the powerful and versatile 150MHz Arm® Cortex® -M4F based MCU. This evaluation kit is a motor controller and driver evaluation PCB, that uses PAC5523 Power Application Controller®.To aid in evaluation and application development the PAC5523EVK1 offers access to all of the PAC5523 device’s signals by means of a series of female header connectors.

The PAC5523EVK1 can be used with the include reference firmware for sensored BLDC, sensorless BEMF and sensorless FOC control. Each firmware suite includes a graphical user interface (GUI) that runs on a Windows platform for evaluation and debugging of the user application. The ET-COLINK-1 and ET-UARTISO-1 adapters can be used for FLASH programming using SWD and GUI communication using the UART on the PAC5523.

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.

PAC5523 BLDC Application Firmware
Installer for the PAC5523 BLDC application firmware, which implements sensorless BEMF motor control on the PAC5523 device. 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.

PAC55XX FOC Application Firmware
Installer for the PAC ® FOC application firmware designed to show case motor control using sensorless Field Oriented Control (FOC) on all members of the PAC ® family of 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, Eclipse, and CooCox CoIde 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.

PAC55XX Software Development Kit
Installer for the PAC55XX Software Development Kit (SDK) that provides register level definitions and peripheral driver APIs for developing ARM M4 application firmware on all PAC55XX devices. The PAC55XX SDK is a unified SDK that supports Keil µVision IDE, IAR Systems Embedded Workbench for ARM (EWARM) IDE, and GCC tool chains.

 

PAC55XX IDE Support
Development of application firmware for PAC55XX ARM Cortex ® M4 is made easy with standard integrated development environments (IDEs). PAC55XX can be used with the most popular integrated IDEs including Keil MDK(uVision), IAR Systems Embedded Workbench for ARM, Eclipse, and Coocox CoIDE.
