Echelon Series 6000 Chip databook - Manual (Page 164)

• VDD3V3 pins: 8, 18, 29, 30, 31, 41
• VDD1V8 pins: 6, 16, 27, 44
Recommendation: Add an additional 1.0 μF (6.3 V, 10%, X7R) capacitor to pin 27 to
provide extra protection and stability for the Series 6000 chip’s internal voltage regulator.
Figure 58 shows suggested bypass capacitor placement and crystal circuit trace outlines. See
Pin Connections for additional information about placing these capacitors.
