dsPIC30/33
The dsPIC30 series is for those of you in need of 5 V of operation (2.5 to 5.5 V). This family comes in four varieties: general-purpose, sensor, motor control, and power conversion, all operating at 30 MIPS. Each flavor has peripherals based on general or specific applications. For instance, the sensor family is based on low-pin-count devices in support of high-performance yet cost-sensitive applications. The motor control family includes a quadrature encoder for position and velocity feedback. Analog comparators and high-speed ADCs and PWMs in the power conversion family are needed for SMPS, UPS, and power-factor-correction applications. The general-purpose family features codec support for speech and audio applications.
Executing at 40 MIPS (3.3 V), the dsPIC33 family has the highest performance. The general-purpose family (GP) has both low-pin-count devices for sensor applications and larger devices with codec interfaces and DMA. The motor control and power conversion family (MC) has quadrature encoders and DMA.
