Active-Semi PAC5220 Power Application Controllers™

Active-Semi PAC5220 Power Application Controllers™

Active-Semi's PAC5220 Power Application Controllers™ 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 power and general purpose application systems ranging from digital power supply to motor control. 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.
