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.

Mini-PCI Express Online Standards and Specifications

PCI: The original specification 'Peripheral Component Interface', [parallel interface]
PCI Express Bus: [used in desktop computers, the physical layer is not compatible with the PCI bus]
PCIe Mini Card Electromechanical Specification [used in Notebook/Laptop computers]

PCISIG {Peripheral Component Interconnect - Special Interest Group}

Mini PCI Express Connector Manufacturers

A Mini-PCI Express connector accepts a 52-pin card edge with one key slot. The Board has fingers at the card edge, the card key is an absence of fingers.

PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, and Mini PCI-E) is a replacement for the Mini PCI form factor based on PCI Express. It is developed by the PCI-SIG. The host device supports both PCI Express and USB 2.0 connectivity, and each card uses whichever the designer feels most appropriate to the task. Most laptop computers built after 2005 are based on PCI Express and can have several Mini Card slots.
