Appendix A Electrical Characteristics
The VDDF
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.
A.1.3
There are four groups of functional pins.
A.1.3.1
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
This group is made up by the V
