1.6 Cautions for Circuit Setup
1.6.1 Usage Notes
Connection of VDD30 and VSS
VDD30 and VSS pins should be connected directly to the power supply and ground respectively.
Do not mount the LSI on the printed circuit board in the wrong direction in order not to destroy it because of the
meltdown of wiring due to large current etc..
Cautions for Operation
1. If the LSI is used close to high-field emissions (under the cathode ray tube, etc.), shield the package surface to
ensure normal performance.
2. Operation temperature should be well considered. If the temperature is over the guaranteed value, unexpected
operation could be occurred.
3. Operation voltage should be also well considered.
• If the operation voltage is over the operating range, reliability (lifetime due to the aged deterioration) can
not be guaranteed.
• If the operating voltage is below the operating range, unexpected operation could be occurred.
