LC88FC3K0A
■ Power Pin Treatment Conditions 1 (VDD1, VSS1)
Connect capacitors that meet the following conditions between the VDD1 and VSS1 pins :
- Connect among the VDD1 and VSS1 pins and the capacitors C1 and C2 with the shortest possible lead wires,
of the same length (L1=L1', L2=L2') wherever possible.
- Connect a large-capacity capacitor C1 and a small-capacity capacitor C2 in parallel.
The capacitance of C2 should be approximately 0.1F or larger.
- The VDD1 and VSS1 traces must be thicker than the other traces.

■ Power Pin Treatment Conditions 2 (VDD2, 3, 4 and VSS2, 3, 4)
Connect capacitors that meet the following condition between the VDD2, 3, 4 and VSS2, 3, 4 pins :
- Connect among the VDD2, 3, 4 and VSS2, 3, 4 pins and the capacitor C3 with the shortest possible lead
wires, of the same length (L3=L3') wherever possible.
- The capacitance of C3 should be approximately 0.1F or larger.
- The VDD2, 3, 4 and VSS2, 3, 4 traces must be thicker than the other traces.
