2.3 VDD and VSS
Technical Data
Power is supplied to the microcontroller via these pins. VDD is the
positive supply and VSS is ground. The MCU operates from a single 5V
(nominal) power supply.
It is in the nature of CMOS designs that very fast signal transitions occur
on the MCU pins. These short rise and fall times place very high short-
duration current demands on the power supply. To prevent noise
problems, special care must be taken to provide good power supply
bypassing at the MCU. Bypass capacitors should have good high-
