Freescale公司的MC56F84xx系列是基于32位DSP核的数字信号控制器(DSC),包括有高速度和高精度外设如312微微秒分辨率的PWM以及内置了PGA的双路高速12位ADC(取样频率高达3.3MSPS)和一个高精度16位ADC,具有极好的精度,检测和控制,适用于最大效率的数字电源转换和高端马达控制如太阳能逆变器,开关电源,智能传感器,无线充电和S-FSK动力线调制解调器等.本文介绍了MC56F84xx主要特性,系统方框图, TWR-56F8400 MCU模块主要特性,方框图,电路图和材料清单(BOM).
The MC56F84xx is based on our newly designed 32-bit DSP core. It is the market’s fastest digital signal-processing MCU offering exceptional precision, sensing and control for the most efficient digital power conversion and advanced motor control applications. The MC56F84xx includes advanced high-speed and high-accuracy peripherals such as high-resolution pulse width modulation (PWM) with 312 pico-second resolution and dual, high-speed 12-bit analog-to-digital converters (ADCs) with built-in PGA sampling up to 3.3 mega samples per second (Msps) and one high-precision 16-bit ADC. Faster application-specific control loops are driven via a high-speed 32-bit DSP core with single-cycle math computations, fractional arithmetic support and parallel moves.
