NOTES
power supply wire patterns (VCC patterns) should designed wide possible order reduce parasitic impedance. Also, patterns which connected pins device must handled designed analog system pattern their circuit patterns must separate from digital system patterns other peripheral devices.
Power Supply Patterns
Switching Noise
order reduce switching noise much possible, high-frequency bypass capacitor must connected between pins pins. this case, capacitor should connected pins near possible.
