Three dsPIC33F General Purpose Family members and three dsPIC33F Motor Control/Power Conversion Family DSCs have been added to Microchip’s low pin-count, 16-bit digital signal controller (DSC) product line. The General Purpose DSCs feature 16 or 32 Kbytes of Flash memory with 28- or 44-pin packages and provide a pin- and code-compatible migration path for PIC24 microcontrollers. The devices also feature an on-chip Analog-to-Digital-Converter (ADC), with up to 1.1 Ms/s, and serial interfaces such as I2C, SPI and UART. The three dsPIC33F Motor Control Family DSCs add a motor-control PWM with two independent clock sources for advanced motor control or inverter algorithms as well as active power factor correction using a single DSC. Both the General Purpose and Motor Control DSCs also feature Peripheral Pin Select, which allows designers to remap digital I/O to optimize board layout—enabling smaller boards, less noise and the use of a lower pin count DSC.
