■ HANDLING DEVICES
Preventing Latch-up
Care must be taken to ensure that maximum voltage ratings are not exceeded when they are used.
Latch-up may occur on CMOS ICs if voltage higher than VCC or lower than VSS is applied to input and output pins
other than medium- and high-withstand voltage pins or if higher than the rating voltage is applied between VCC
pin and VSS pin.
When latch-up occurs, power supply current increases rapidly and might thermally damage elements.
Also, take care to prevent the analog power supply voltage (AVCC) and analog input voltage from exceeding the
digital power supply voltage (VCC) when the analog system power supply is turned on or off.
Stable Supply Voltage
Supply voltage should be stabilized.
A sudden change in power-supply voltage may cause a malfunction even within the guaranteed operating range
of the Vcc power-supply voltage.
For stabilization, in principle, keep the variation in Vcc ripple (p-p value) in a commercial frequency range
(50/60 Hz) not to exceed 10% of the standard Vcc value and suppress the voltage variation so that the transient
variation rate does not exceed 0.1 V/ms during a momentary change such as when the power supply is switched.
Precautions for Use of External Clock
Even when an external clock is used, oscillation stabilization wait time is required for power-on reset, wake-up
from sub clock mode or stop mode.
Serial communication
There is a possibility to receive wrong data due to noise or other causes on the serial communication.
Therefore, design a printed circuit board so as to avoid noise.
Consider receiving of wrong data when designing the system. For example apply a checksum and retransmit
the data if an error occurs.
PIN CONNECTION
Treatment of Unused Pin
Leaving unused input pins unconnected can cause abnormal operation or latch-up, leaving to permanent damage.
Unused input pins should always be pulled up or down through resistance of at least 2 k
Ω. Any unused input/
output pins may be set to output mode and left open, or set to input mode and treated the same as unused input
pins. If there is unused output pin, make it open.
Treatment of Power Supply Pins on A/D Converter
Connect to be AVCC
= VCC and AVSS = VSS even if the A/D converter is not in use.
Noise riding on the AVCC pin may cause accuracy degradation. So, connect approx. 0.1
μF ceramic capacitor
as a bypass capacitor between AVCC and AVSS pins in the vicinity of this device.
