The PAC5210 belongs to Active-Semi’s broad portfolio of full-featured Power Application ControllerTM (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® CortexTM-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 Drivers™ to form the most compact microcontroller-based power and general purpose application systems ranging from digital power supply to motor control. The PAC5210 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. The Multi-Mode Power Manager (MMPM) provides “all-in-one” efficient power management solution for multiple types of power sources. It features a configurable multi-mode switching supply controller capable of operating in buck, flyback, or boost mode, and up to four linear regulated voltage supplies. The Application Specific Power Drivers (ASPD) is medium voltage level open drain driver for 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 inter-connectible signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals. Together, these modules and microcontroller enable a wide range of compact applications with highly integrated power management, driving, feedback, and control for DC supply up to 52V and for line AC supply.

Supporting Evaluation Tools


The ET-COLINK-1 adapter allows the user to program and perform source leveldebugging 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.
