The PAC5232 is a Power Application Controller (PAC) product that is optimized for high-speed motor control and driving. The PAC5232 integrates a 50MHz ARM Cortex® -M0 32-bit microcontroller core with a highly-configurable Power manager, Active-Semi’s proprietary and patent-pending Configurable Analog Front-EndTM and Application Specific Power DriversTM to form the most compact microcontroller-based power and motor control solution available.
The PAC5232 microcontroller features 32kB of embedded FLASH and 8kB of SRAM memory, a 1MSPS analog-to-digital converter (ADC) with programmable auto-sequencer, 3.3V/5V IO, flexible clock control system, PWM and general-purpose timers and several serial communications interfaces. The Configurable Power Manager (CPM) provides “all-in-one” efficient power management solution for multiple types of power sources. It features a configurable high-voltage switching supply controller capable of operating a buck converter, a configurable medium-voltage switching regulator, and four linear regulated voltage supplies. The Application Specific Power Drivers (ASPD) are 180V power drivers designed for half bridge, H-bridge, 3-phase, and general purpose driving. The Configurable Analog Front End (CAFE) comprises differential programmable gain amplifiers, single-ended programmable gain amplifiers, comparators, digital-to-analog converters, and I/Os for programmable and interconnectible signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals.

The PAC5232EVK1 can be used with Active-Semi’s BLDC/BEMF or FOC firmware and Windows GUI for evaluation and debugging of the application. The ET-COLINK-1 may be used for connecting the EVK to a Windows PC using a USB cable, for programming and debugging using an IDE. The ET-UARTISO-1 may be used for connecting the Windows PC to the device’s UART for the Windows GUI.
Supporting Evaluation Tools
Installer for the PAC5232 BLDC application firmware, which implements sensored BLDC and sensorless BEMF motor control on the PAC5232. 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.
