3.3 Pin layout
4. Recommended Circuit Diagram
4.1 Basic schematic Design of the WizFi630S
When designing the schematic, the USB HOST line (PADP & PADM) should be paired with the Ethernet
line P & M (ex: TXOP0, TXOM0). C37 must be close to the 3.3V and connecting C38 to the Mini PCI
Express port will decrease noise.

4.2 USB Host Schematic Design
We recommend pairing the USB HOST P and N line, and also place the diode as shown below for ESD
protection

4.3 LED Schematic Design
4.4 Ethernet Schematic Design
We also recommend paring the P and N line for Ethernet schematic, and do not place R, L, C, other
sign lines below the RJ-45 schematic (especially not below the pair line).
The Center-Tap of WizFi630S connects to GND whereas the Center-Tap of WizFi630A operates in 1.8V
~ 3.3V.
Another recommendation is to isolate the CH_GND and GND with a 1nF/2kV capacity.

4.5 Switch Schematic Design
4.6 UART0 Micro USB Schematic Design
Micro USB P should be paired with N line, and we recommend placing the diode as shown below for
ESD protection.

5. Power Supply
Power supply is one of the critical parts in the design stage that will affect the performance so please
refer to the guidelines below.

Description
Voltage Rating
DC 3.3V
Current Rating
1A
Caution
You must not exceed the voltage rating of DC 3.3V, otherwise WizFi630S will not operate as designed
and could cause damage to the device. Also, please design with at least 1.5 or 2 times more current
rating (1.5A) ~ (2A) for similar reasons specified ahead.
6. Power Supply
Refer to the Mini PCIe socket datasheet since WizFi630S uses a Mini PCIe connector.
