PIC32MX1XX/2XX
1.0 DEVICE OVERVIEW
Note 1: This data sheet summarizes the features
of the PIC32MX1XX/2XX family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the related section of 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
PIC32MX1XX/2XX devices.
Figure 1-1 illustrates a general block diagram of the
core and peripheral modules in the PIC32MX1XX/2XX
family of devices.
Table 1-1 lists the functions of the various pins shown
in the pinout diagrams.
