Frequently Answers and Questions

What is the dual footprint design?
The dual footprint design refers to the fact that the Intel® Gigabit Ethernet Controllers and the Platform LAN Connect components are all manufactured in a 15 mm x 15 mm, 196-ball grid array package with the same ball pattern. This allows the designer to create a single LAN on Motherboard design that accommodates all devices.
What are the key differences between the Gigabit Ethernet Controllers and the Platform LAN Connect devices?
The 82562EZ(EX) Platform LAN Connect device uses a LAN Connect Interface (LCI) to connect to the I/O Control Hub 5 (ICH5). The 82540EP and 82541 controllers provide 32-bit interfaces for a 33 MHz or 66 MHz PCI bus meeting PCI 2.3 Specifications. The 82562EZ(EX) is designed for 10/100 Mbps Ethernet, while the 82540EP/82541xx controllers are designed for 10/100/1000 Mbps Ethernet.
How do I disable the LAN port on the 82541xx controller?
The 82541xx controllers have a LAN disable function on the FLSH_SO (ball P9). This pin can be connected to a Super IO component to allow the BIOS to disable the Ethernet port.
What are the power supply requirements for the 82562EZ(EX) device?
The 82562EZ(EX) Platform LAN Connect device uses a single 3.3 V power supply. The 3.3 V supply must provide approximately 90 mA current for full speed operation. Standby power must be furnished in order to wake up from powerdown.
How do I choose the correct crystal for my design?
Intel recommends a crystal frequency of 25 MHz. For the 82541EI/GI devices, Intel® recommends choosing a crystal with a ESR value of 20 Ω or less, an equivalent Cload of 18 pF, and a maximum of 30 ppm frequency shift. Cload is defined to be the load capacitance of the crystal, specified by the crystal vendor.
