dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X AND PIC24EPXXXGP/MC20X
1.0 DEVICE OVERVIEW
This document contains device-specific information for
the dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X and PIC24EPXXXGP/MC20X Digital Signal
Controller (DSC) and Microcontroller (MCU) devices.
dsPIC33EPXXXMC20X/50X and dsPIC33EPXXXGP50X
devices contain extensive Digital Signal Processor
(DSP) functionality with a high-performance, 16-bit
MCU architecture.
Figure 1-1 shows a general block diagram of the core
and peripheral modules. Table 1-1 lists the functions of
the various pins shown in the pinout diagrams.
