PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family
A.10 Package Differences
In general, PIC32MZ EF devices are mostly pin com-
patible with PIC32MX5XX/6XX/7XX devices; how-
ever, some pins are not. In particular, the VDD and
V
SS pins have been added and moved to different
pins. In addition, I/O functions that were on fixed
pins now will largely be on remappable pins.
TABLE A-11: PACKAGE DIFFERENCES
PIC32MX5XX/6XX/7XX Feature PIC32MZ EF Feature
V
CAP Pin
On PIC32MX devices, an external capacitor is required between
a V
CAP pin and GND, which provides a filtering capacitor for the
internal voltage regulator.
On PIC32MZ EF devices, this requirement has been removed.
A low-ESR capacitor (typically 10 µF) is required on the V
CAP
pin.
No VCAP pin.
V
DD and VSS Pins
There are more V
DD pins on PIC32MZ EF devices, and many
are located on different pins.
V
DD on 64-pin packages: 10, 26, 38, 57
V
DD on 100-pin packages: 2, 16, 37, 46, 62, 86
V
DD on 64-pin packages: 8, 26, 39, 54, 60
V
DD on 100-pin packages: 14, 37, 46, 62, 74, 83, 93
There are more V
SS pins on PIC32MZ EF devices, and many are
located on different pins.
V
SS on 64-pin packages: 9, 25, 41
V
SS on 100-pin packages: 15, 36, 45, 65, 75
V
SS on 64-pin packages: 7, 25, 35, 40, 55, 59
V
SS on 100-pin packages: 13, 36, 45, 53, 63, 75, 84, 92
PPS I/O Pins
Peripheral functions on PIC32MZ EF devices are now routed
through a PPS module, which routes the signals to the desired
pins. When migrating software, it is necessary to initialize the
PPS I/O functions in order to get the signal to and from the cor-
rect pin.
All peripheral functions are fixed as to what pin upon which they
operate.
PPS functionality for the following peripherals:
•CAN
•UART
• SPI (except SCK)
• Input Capture
• Output Compare
• External Interrupt (except INT0)
• Timer Clocks (except Timer1)
• Reference Clocks (except REFCLK2)
