PIC32MX3XX/4XX
1.0 DEVICE OVERVIEW
Note 1: This data sheet summarizes the features
of the PIC32MX3XX/4XX family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “PIC32 Family
Reference Manual”, which is available
from the Microchip web site
(www.microchip.com/PIC32).
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 PIC32MX3XX/4XX devices.
Figure 1-1 illustrates a general block diagram of the core
and peripheral modules in the PIC32MX3XX/4XX family
of devices.
Table 1-1 lists the functions of the various pins shown
in the pinout diagrams.
