描述 Description

Qorvo's PAC55711 expands Qorvo's broad portfolio of full-featured Power Application Controller? (PAC) products - highly optimized System On Chip (SOC) for controlling and powering next generation smart energy appliances, devices, and equipment – by adding new features such as VDS Sensing, Cycle By Cycle (CBC), Enhanced Sample And Hold (S&H), Windowed Watchdog Timer, hardware based nBRAKE and nDRVDIS for safety based applications with external safety MCU support. This application controller integrates a 150MHz Arm? Cortex?-M4F 32-bit microcontroller core with Qorvo'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.
The product's microcontroller features up to 128kB of embedded FLASH and 32kB of SRAM memory, a high-speed 12-bit 2.5 MSPS analog-to-digital converter (ADC) with dual auto-sampling sequencers, 5.0V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
