The PAC5222 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 Manager™, Configurable Analog Front End™, and Application Specific Power Drivers™ to form the most compact microcontroller-based motor control and drive solutions for BLDC and PMSM motors. The PAC5222 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.

 

Advantages of our Intelligent Motor Control

FEATURES BENEFITS
Programmable 32-bit MCU Allows implementation of high-performance advanced control algorithms such as Field Oriented Control (FOC), Sensorless BEMF, Sensored BLDC and serial communications protocols
Integrated Power Manager Removes the need for an external DC/DC Controller. Provides 5V/200mA system supply for additional PCB peripherals. Integrates all power rails for MCU, FLASH, Analog and gate drivers
Integrated Gate Drivers Removes the need external open-drain driver circuits
Integrated Signal Chain Allows integrated Current, Voltage and Temperature sensing and protection using integrated Differential and Single-ended Programmable-Gain Amplifiers, comparators and DACs
Lowest standby power Allows 18µA Iq for standby-mode

PAC5222EVK1

Active-Semi’s PAC5222EVK1 development platform is a complete hardware solution enabling users not only to evaluate the PAC5222 device, but also develop power applications revolving around this powerful and versatile Arm® Cortex®-M0 based microcontroller. The module contains a PAC5222 Power Application Controller® (MCU) and all the necessary circuitry to properly energize the MCU and its internal peripherals once power is applied.
To aid in the application development the PAC5222EVK1 offers access to each and every one of the PAC5222 device’s signals by means of a series of male 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.
