PC Card Standard Volume 2
The Electrical Specification describes the connector pinout, interface protocol, signaling environment,
interface timings, programming model, and specifics of card insertion, removal, power up, and
configuration. It is organized in three sub-sections dealing with items common to all interfaces, 16–bit
PC Card interface specifics, and CardBus PC Card interface specifics.
The PC Card Standard continues an evolutionary process by providing additional capabilities thereby
expanding the variety of PC Cards that can be supported. This release enables a new generation of PC
Cards based on the Universal Serial Bus (USB). This new generation combines the benefits of the PC
Card format with the ease-of-use capabilities of USB.
As a result, the spectrum of applications that can be supported by PC Cards has again been
broadened. Just as PCMCIA 2.0 / JEIDA 4.1 evolved the PCMCIA 1.0 / JEIDA 4.0 memory only
interface by adding I/O capability, and Release 5.0 of the PC Card Standard added 32-bit PCI-based
functionality, this new release evolves to include the capabilities outlined below
