The PAC5220 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 ManagerTM, Configurable Analog Front EndTM, and Application Specific Power DriversTM to form the most compact microcontroller-based power and general purpose application systems. The PAC5220 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

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

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.
