Appendix A Electrical Characteristics
A.1.3
There are four groups of functional pins.
A.1.3.1
Those I/O pins have a nominal level of 3.3V or 5V depending on the application operating point. This
group of pins is comprised of all port I/O pins, the analog inputs, BKGD pin and the RESET inputs.The
internal structure of all those pins is identical, however some of the functionality may be disabled.
A.1.3.2
This group of pins is comprised of the VRH and VRL pins.
A.1.3.3
The pins XFC, EXTAL, XTAL dedicated to the oscillator have a nominal 2.5V level. They are supplied by
VDDPLL.
A.1.3.4
This pin is used for production testing only.
A.1.4
Power supply must maintain regulation within operating V
operating maximum current conditions. If positive injection current (V

VDD1, VSS1, VDD2 and VSS2 are the supply pins for the internal logic.
VDDPLL, VSSPLL supply the oscillator and the PLL.
VSS1 and VSS2 are internally connected by metal.
VDD1 and VDD2 are internally connected by metal.
VDDA, VDDX, VDDR as well as VSSA, VSSX, VSSR are connected by anti-parallel diodes for
ESD protection.

TEST
In the following context VDD5 is used for either VDDA, VDDR and
VDDX; VSS5 is used for either VSSA, VSSR and VSSX unless otherwise
noted.
IDD5 denotes the sum of the currents flowing into the VDDA, VDDX and
VDDR pins.
VDD is used for VDD1, VDD2 and VDDPLL, VSS is used for VSS1, VSS2
and VSSPLL.
IDD is used for the sum of the currents flowing into VDD1 and VDD2.
