1.0 DEVICE OVERVIEW
Note 1: This data sheet summarizes the fea-
tures of the dsPIC33EPXXXGP50X,
dsPIC33EPXXXMC20X/50X,
and
PIC24EPXXXGP/MC20X families of
devices. It is not intended to be a com-
prehensive resource. To complement
the information in this data sheet, refer
to the related section of the “dsPIC33E/
PIC24E Family Reference Manual”,
which is available from the Microchip
web site (www.microchip.com)
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
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.
