Reserved Pin

The pin number 7 should be pull-up.

The reserved pins except the pin number 7

should be pull-down or GND.

 Notes: Pull-Up/Down registor = 40KΩ to 100KΩ. Typical value are 75KΩ.

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 W520

0 core

operation. It should not be connected to the

power of other devices.
