dsPIC33F 16-Bit Digital Signal Controllers Microchip Technology Microchip dsPIC33F Digital Signal Controllers (DSCs) offer the performance of a DSP with the simplicity of an MCU. The dsPIC33F core is designed to execute digital filter algorithms, high-speed precision digital control loops, and digital audio and speech processing. The dsPIC33F DSCs with Motor Control peripherals enable the design of high-performance, precision motor control systems. The dsPIC33F SMPS DSCs provide on-chip peripherals specifically designed for high-performance, digital power supplies. SMPS peripherals include high speed and high-resolution PWM, fast ADC, and analog comparators.
