Mini PCI Express Bus Description

A Brief Description of the MiniCard interface. MiniCard is also called Mini PCI Express bus [PCI= Peripheral Component Interface]. The Minicard is a small form factor board used to implement the PCI Express interface on Notebook computers. The card size is 30mm wide by 50.95mm long by 5mm high. The Minicard uses a 52-pin card edge connector, the card pins are fingers at the edge of the card. MiniCard is used to implement both the 1x PCI Express Bus interface and a USB 2.0 interface.

Mini PCI Express Bus Interface IC Manufacturers

Refer to the main PCI Express Bus for a list of manufacturers producing interface IC's
Like other PC buses, there are no glue logic devices just ASICs and chip sets in PCI Express; Similar to PCI. Refer to the LVDS page for additional information on the LVDS electrical interface. This page provides a comparison of Interface Switching levels for different types of electrical standards.
