32 Bit PCI Slot – How to Use in an Industrial Rackmount Computer

If you’re configuring a new Computer System for Industry, you likely have devices requiring PCI expansion slots. The 32 bit PCI slot offers advantages over other standards.

The 32-bit Peripheral Component Interconnect bus, commonly known as 32-bit PCI is a local bus standard is used for attaching peripheral devices to a computer. Devices such as integrated circuits that are fitted onto the motherboard, or expansion cards are typically what’s used in these slots.

This PCI bus provides direct access to system memory for connected devices, and has replaced the ISA and VESA Local Bus standards. It uses a bridge to connect to the front side bus and therefore to the CPU. The PCI bus originally operated at 33 MHz using a 32-bit-wide path. slot88

Advantages to using PCI with 32 bit include:

*Increased Transfer Rate: Revisions to the standard include increasing the speed from 33 MHz to 66 MHz and doubling the bit count to 64, increasing the rate of information transfer for your device card.

*Supports Multiple Voltages: PCI in 32 bit supports devices that use either 5 volts or 3.3 volts.

*Size: 32-bit PCI cards use 47 pins. The PCI bus is able to work with so few pins because of hardware multiplexing, which means that the device sends more than on signal over a single pin.

32-bit PCI slots should be an important part of your next Industrial Computer configuration, but it’s becoming harder to find suppliers who sell them. Make sure your supplier has the engineering skills to meet your PCI needs
