MC56F84xx: Digital Signal Controllers

Thu, 07/05/2012 - 6:45am

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.
