Is Cardbus a PCMCIA?
Cardbus is an extension of the latest PCMCIA standard, which expands the bus bandwidth and throughput to 32 bits at 33MHz. In contrast, the older PC card standard was 16 bits at 8MHz. Cardbus is analogous to the PCI slots in desktops, while the older PC card standard is analogous to ISA.
What is a PCMCIA card slot?
PCMCIA cards are hardware interfaces that are slightly bigger than a standard credit card and enable additional functionality for laptop computers and portable devices. If you’re familiar with expansion cards in desktop computers, you can think of a PCMCIA card as an expansion card for a laptop.
What is a Cardbus adapter?
A network or communications controller that plugs into a PC Card slot on a laptop computer. It often refers to a wired or wireless Ethernet network adapter on a Type II card.
How does PCMCIA card work?
The PCMCIA card is plugged into a host socket/adapter on the computer’s motherboard or connected to its expansion bus. The socket side has the standard 68-pin interface for the card. The adapter side translates the PCMCIA interface signals to match the computer’s bus standards.
What does a CardBus do?
CardBus is effectively a 32-bit, 33 MHz PCI bus in the PC Card design. CardBus supports bus mastering, which allows a controller on the bus to talk to other devices or memory without going through the CPU. Many chipsets, such as those that support Wi-Fi, are available for both PCI and CardBus.
Are pcmcia cards obsolete?
From 1990 onwards, the association published and maintained a sequence of standards for parallel communication peripheral interfaces in laptop computers, notably the PCMCIA card, later renamed to PC Card, and succeeded by ExpressCard (2003), all of them now technologically obsolete.
What are the ExpressCard types?
There are two standard formats of ExpressCard modules: the ExpressCard/34 module (34mm x 75mm) and the ExpressCard/54 module (54mm x 75mm). Both formats are 5mm thick, the same as the Type II PC Card. The standard module length is 75mm, which is 10.6mm shorter than a standard PC Card.
