Mini PCI

Mini PCI is an older expansion card form factor designed specifically for portable computers, featuring a much smaller size but slower speeds than other PCI cards. It was replaced by PCI Express Mini Card in 2003.

What does Mini PCI mean?

Mini PCI, short for Mini Peripheral Component Interconnect, is a compact expansion card form factor introduced by Intel in 1995. It is designed to provide a standardized interface for connecting various peripherals to a host computer’s motherboard. Mini PCI cards are typically used in laptops, embedded computers, and other small form-factor devices where space is constrained.

Mini PCI cards are typically half the size of standard PCI cards, measuring 30mm x 50.9mm. They Feature a 68-pin interface with support for 32-bit or 64-bit data transfers. Mini PCI cards can be connected to the host computer’s PCI bus, allowing them to access the system’s memory and other peripherals.

Applications

Mini PCI is used in a wide range of applications, including:

  • Wireless networking: Mini PCI cards are commonly used to add wireless networking capabilities to laptops and other devices. They support various wireless standards, including Wi-Fi, Bluetooth, and WWAN.
  • Storage: Mini PCI cards can be used as storage devices, providing additional storage space for laptops and other portable devices. They typically use solid-state drives (SSDs) to offer high performance and reliability.
  • Audio and Video: Mini PCI cards can be used to add audio and video capabilities to devices. They can include sound cards, video capture cards, and TV tuners.
  • Industrial automation: Mini PCI cards are used in various industrial automation applications, providing interfaces for connecting sensors, actuators, and other devices.

History

Mini PCI was developed in the mid-1990s as a compact alternative to standard PCI cards. It was initially intended for use in laptops and other portable devices where space was limited. The first Mini PCI cards were released in 1995, and the form factor quickly gained popularity due to its small size and versatility.

Over the years, Mini PCI has undergone several revisions to improve its capabilities. Mini PCI-Express (Mini PCIe) was introduced in 2005, offering faster data transfer speeds and support for the PCI Express bus. Mini PCIe is now the dominant form factor for expansion cards in laptops and other small devices.

Mini PCI continues to be an important technology Today, providing a standardized interface for connecting a wide range of peripherals to host computers. Its compact size and versatility make it ideal for use in space-constrained devices, such as laptops, embedded computers, and industrial automation equipment.
