Microchip Technology 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.
The Microchip Technology dsPIC33F 16-Bit Digital Signal Controllers are offered in a wide variety of compact packages for design flexibility. Package pincounts include 44-pin (TQFP, QFN and VTLA), 28-pin (QFN, SOIC, PDIP, and SSOP), 20-pin (SSOP), and 18-pin (PDIP and SOIC) options.
