PRELIMINARY
As a measure against power supply noise, connect a capacitor of about 0.1
F as a bypass capacitor
between VCC and VSS as close as possible to VCC and VSS pins.
7.
Crystal Oscillator Circuit
Noise at X0 or X1 pins may possibly cause abnormal operation. Make sure to provide bypass capacitors with
shortest distance to X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and make sure, to
the utmost effort, that lines of oscillation circuit not cross the lines of other circuits.
It is highly recommended to provide a printed circuit board art work surrounding X0 and X1 pins with a ground
area for stabilizing the operation.
It is highly recommended to evaluate the quartz/MCU system at the quartz manufacturer.
8.
Turn on Sequence of Power Supply to A/D Converter and Analog Inputs
Make sure to turn the A/D converter power supply (AVCC, AVRH, AVRL) and analog inputs (ANn) on after
turning the digital power supply (VCC) on.
Turn the digital power off after turning the A/D converter supply and analog inputs off. In this case, make sure
that the voltage does not exceed AVRH or AVCC (turning the analog and digital power supplies
simultaneously on or off is acceptable).
9.
Connection of Unused Pins of A/D Converter
Connect unused pins of A/D converter as AVCC = VCC, AVSS = AVRH = AVRL = VSS.
10. Notes on Energization
To prevent malfunction of the internal voltage regulator, supply voltage profile while turning the power supply
on should be slower than 50
s from 0.2 V to 2.7 V.
11. Stabilization of power supply voltage
If the power supply voltage varies acutely even within the operation assurance range of the Vcc power supply
voltage, a malfunction may occur. The Vcc power supply voltage must therefore be stabilized. As stabilization
guidelines, stabilize the power supply voltage so that Vcc ripple fluctuations (peak to peak value) in the
commercial frequencies (50 to 60 Hz) fall within 10% of the standard Vcc power supply voltage and the
transient fluctuation rate becomes 0.1V/
s or less in instantaneous fluctuation for power supply switching.
