1.4  Power Supply Signals 
Symbol  Type  Pin No  Description 
VCC3V3A  Power  11, 15, 23  3.3V power supply for Analog part 
VCC3V3  Power  27, 47  3.3V power supply for Digital part 
VCC1V8  Power  8, 25  1.8V power supply for Digital part 
GNDA  Ground  13, 19, 22, 24
Analog ground 
GND  Ground  9, 10, 26, 
28, 48 
Digital ground 
1V8O  O  14  1.8V regulator output voltage 
1.8V/200mA  power  created  by  internal  power 
regulator,  is  used  for  core  operation  power 
( VCC1V8).   
Be  sure  to  connect  tantalum  capacitor  between 
1V8O  and  GND  for  output  frequency 
compensation,  and  selectively  connect  0.1uF 
capacitor  for  high  frequency  noise  decoupling. 
Notice:  1V8O  is  the  power  for  W5200  core 
operation. It  should not be  connected to  the 
power of other devices.
