The PAC5524 belongs to Active-Semi’s Power Application Controller (PAC) family. The PAC family of products are highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC. The PAC5524 integrates a high-performance, high-memory FLASH-based 150MHz Arm® Cortex-M4F®, Power Management , High-side and low-side Gate Drivers and Signal-Conditioning components in a single product.

The PAC5524 is optimized for high-performance battery-powered BLDC motor control applications up to 48V.

PAC5524EVK1

Active-Semi’s PAC5524EVK1 evaluation kit is a complete hardware solution enabling users to evaluate the PAC5524 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 the PAC5524 Power Application Controller®. To aid in evaluation and application development the PAC5524EVK1 offers access to all of the PAC5524 device’s signals by means of a series of female header connectors.

Supporting Evaluation Tools

The ET-UARTSWD adapter is the preferred adapter for evaluation of PAC devices/firmware and combines a USB to UART adapter with SWD debugger connector adaptation into a single board with isolation. The ET-UARTISO-1 adapter provides only the USB to UART adapter with isolation for Active-Semi application GUI communications.

ET-UARTSWD

The ET-UARTSWD isolated communications and debugging interface unifies two modules into one. Previously, interfacing a PC Computer to any of Active-Semi’s PAC5xxx Evaluation Modules required one module to enable UART based serial communications and a second module to allow for in-system debugging and FLASH memory programing.

PAC5xxx Flash Programmer Tools

Active-Semi has partnered with Flash Programmer solution providers to support our Intelligent Motor Control PAC product families.
These proven tools are suitable for emerging and high volume product manufacturing.
Both package level (socketed) and board level Flash programming solutions are available.

Active-Semi will support other vendors familiar with Arm® Serial Wire Debug (SWD) protocol to add PAC product compatibility on their existing Flash programmer platforms.
