NOTE
Connecting VDDR to VSS disables the internal voltage regulator.
The VDDF
,
VSS1 pin pair supplies the internal NVM logic.
The VDD, VSS2 are the supply pins for the internal digital logic.
VDDPLL, VSSPLL pin pair supply the oscillator and the PLL.
VSS1, VSS2 and VSS3 are internally connected by metal.
VDDA1, and VDDA2 are internally connected by metal.
All VDDX pins are internally connected by metal.
All VSSX pins are internally connected by metal.
VDDA is connected to all VDDX pins by diodes for ESD protection such that VDDX must not exceed
VDDA by more than a diode voltage drop. VDDA can exceed VDDX by more than a diode drop in order
to support applications with a 5V A/D converter range and 3.3V I/O pin range.
VSSA and VSSX are connected by anti-parallel diodes for ESD protection.
NOTE
In the following context V
DD35
is used for either VDDA, VDDR, and
VDDX; V
SS35
is used for either VSSA and VSSX unless otherwise noted.
I
DD35
denotes the sum of the currents flowing into the VDDA and VDDR
pins. The Run mode current in the VDDX domain is external load
dependent.
V
DD
is used for VDD, V
SS
is used for VSS1, VSS2 and VSS3.
V
DDPLL
is used for VDDPLL, V
SSPLL
is used for VSSPLL
I
DD
is used for the sum of the currents flowing into VDD, VDDF and
VDDPLL.
A.1.3
Pins
There are four groups of functional pins.
A.1.3.1
I/O Pins
Standard I/O pins have a level in the range of 3.13V to 5.5 V. This class of pins is comprised of all port I/O
pins (including PortAD), BKGD and the RESET pins.The internal structure of all those pins is identical;
however, some of the functionality may be disabled. For example the BKGD pin pull up is always enabled.
A.1.3.2
Analog Reference
This group is made up by the V
RH
and V
RL
pins.
