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 in the range of 3.15 V to 5.5 V. This class of pins is comprised of all
port I/O pins, the analog inputs, BKGD and the RESET pins.The internal structure of all those pins is
identical; however, some of the functionality may be disabled. For example, for the analog inputs the
output drivers, pull-up and pull-down resistors are disabled permanently.
A.1.3.2
This group is made up by the V
A.1.3.3
The pins XFC, EXTAL, XTAL dedicated to the oscillator have a nominal 2.5 V level. They are supplied
by V
A.1.3.4
This pin is used for production testing only.
A.1.3.5
This pin is used to enable the on-chip voltage regulator.
A.1.4
Power supply must maintain regulation within operating V
operating maximum current conditions. If positive injection current (V
the injection current may flow out of V
regulation. Ensure external V
will be the greatest risk when the MCU is not consuming power; e.g., if no system clock is present, or if
clock rate is very low which would reduce overall power consumption.
