Connect unused pins of A/D converter to AVCC
= VCC, AVSS = AVR = VSS.
10. Notes on energization
To prevent malfunction of the internal voltage regulator , supply voltage profile while turning on the power supply
should be slower than 50
s (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
guide lines, stabilize the power supply voltage so that VCC ripple fluctuations (peak to peak value) in the
commercial frequencies (50 Hz/60 Hz) fall within 10
% of the standard VCC power supply voltage and the transient
fluctuation rate becomes 0.1 V/ms or less in instantaneous fluctuation for power supply switching.
12. Serial communication
There is a possibility to receive wrong data due to the noise or other causes on the serial communication.
Therefore, design a board so as to avoid noise.
Retransmit the data if an error occurs because of applying the checksum to the last data in consideration of
receiving wrong data due to the noise.
13. Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers,
turn on the power again.
14. Correspondence with
+105 °C or more
There is limited reliability if the product is used exceeding TA = +105
°C. Contact the sales or support
representative for this case.
