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.

Active-Semi’s PAC5232EVK1 Evaluation Kit (EVK) is a complete hardware solution enabling users to evaluate and develop motor control applications around this powerful and versatile ARM®Cortex®-M0 based micro-controller. The module contains the PAC5250 Power Application Controller (MCU), IGBT inverter and debugging headers for serial interfaces and GPIO signals that may be used for debugging and evaluation.

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


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.
