PIC32MX3XX/4XX
Revision G (April 2010)
The revision includes the following global update:
• Added Note 2 to the shaded table that appears at
the beginning of each chapter. This new note
provides information regarding the availability of
registers and their associated bits.
This revision also includes minor typographical and
formatting changes throughout the data sheet text.
Major updates are referenced by their respective
section in the following table.
TABLE A-2: MAJOR SECTION UPDATES
Section Name
Update Description
“High-Performance, General Purpose Updated the crystal oscillator range to 3 MHz to 25 MHz (see Peripheral
and USB 32-bit Flash
Features:)
Microcontrollers”
Added the 121-pin Ball Grid Array (XBGA) pin diagram.
Updated Table 1: “PIC32MX General Purpose – Features” and Table 2:
“PIC32MX USB – Features”
Added the following tables:
- Table 3: “Pin Names: PIC32MX320F128L, PIC32MX340F128L,
and PIC32MX360F128L, and PIC32MX360F512L Devices”,
- Table 4: “Pin Names: PIC32MX440F128L, PIC32MX460F256L
and PIC32MX460F512L Devices”
Updated the following pins as 5V tolerant:
Section 1.0 “Device Overview”
Section 2.0 “Guidelines for Getting
Started with 32-bit Microcontrollers”
- 64-pin QFN (USB): Pin 34 (VBUS), Pin 36 (D-/RG3) and Pin 37
(D+/RG2)
- 64-pin TQFP (USB): Pin 34 (Vbus), Pin 36 (D-/RG3), Pin 37
(D+/RG2) and Pin 42 (IC1/RTCC/INT1/RD8)
- 100-pin TQFP (USB): Pin 54 (VBUS), Pin 56 (D-/RG3) and Pin 57
(D+/RG2)
Updated the Pinout I/O Descriptions table to include the device pin
numbers (see Table 1-1)
Updated the Ohm value for the low-ESR capacitor from less than 5 to less
than 1 (see Section 2.3.1 “Internal Regulator Mode”).
Section 4.0 “Memory Organization”
Labeled the capacitor on the VCAP/VDDCORE pin as CEFC in Figure 2-1.
Changed 10 µF capacitor to CEFC capacitor in Section 2.3 “Capacitor on
Internal Voltage Regulator (VCAP/VCORE)”.
Updated all register map tables to include the “All Resets” column.
Separated the PORT register maps into individual tables (see Table 4-21
through Table 4-34).
Section 12.0 “I/O Ports”
Section 22.0 “10-bit Analog-to-Digital
Converter (ADC)”
Section 26.0 “Special Features”
In addition, formatting changes were made to improve readability.
Updated the second paragraph of Section 12.1.2 “Digital Inputs” and
removed Table 12-1.
Updated the ADC Conversion Clock Period Block Diagram (see Figure 22-
2).
Extensive updates were made to Section 26.2 “Watchdog Timer (WDT)”
and Section 26.3 “On-Chip Voltage Regulator”.
