FAQs:

1 What is the WGI210AT S LJXR chip
It is a single port Gigabit Ethernet controller from Intel that integrates both MAC and PHY layers and is a mature network controller with high integration and low power consumption.

2 What network speeds does the chip support
It supports auto negotiation of 10Mbps 100Mbps and 1000Mbps Ethernet speeds and is fully compliant with standard Gigabit Ethernet protocols.

3 What package and pin count does it use
It uses a QFN64 no lead surface mount package with 64 pins and a standard footprint of 9 by 9 millimeters with an exposed thermal pad on the bottom.

4 What host bus interface does it support
It supports the PCI Express 2.1 high speed bus interface which can be configured in single lane or dual lane modes for high speed data exchange with the host CPU.

5 What are the operating voltage and temperature ranges
It uses a multi voltage power supply including 1 point 0V 1 point 8V and 3 point 3V. The industrial grade temperature range is from minus 40 degrees Celsius to plus 85 degrees Celsius.

6 What application scenarios is this chip suitable for
With its high reliability and compact package it is widely used in industrial automation control boards high end embedded systems server network interface cards and devices requiring Gigabit network connectivity.
