Microchip Technology DSPIC33F Digital Signal Processors & Controllers
Microchip Technology DSPIC33F Digital Signal Processors and Controllers are a family of high-performance 16-bit Digital Signal Processors (DSPs) offering 40 MIPS at 3.3V, up to 256KB program Flash, up to 30KB RAM, and packages up to 100 pins. The DSPIC33F DSP family also includes an 8-channel hardware direct memory access (DMA) that allows data transfer between RAM and peripheral while the CPU executes code. The DSPIC33F devices are ideal for high-performance embedded control applications.
