Hot-selling and scarce PCI1225PDV GHK/PDVPC CARD CONTROLLERS QFP208 spot stock

Product Descriptions

The TI PCI1225 is a high-performance PCI-to-PC Card controller that supports two independent card sockets compliant with the 1997 PC Card Standard. The PCI1225 provides a rich feature set that makes it the best choice for bridging between PCI and PC Cards in both notebook and desktop computers. The 1997 PC Card Standard retains the 16-bit PC Card specification defined in PCMCIA Release 2.2 and defines the new 32-bit PC Card (CardBus), capable of full 32-bit data transfers at 33 MHz. The PCI1225 supports any combination of 16-bit and CardBus PC Cards in the two sockets, powered at 5 V or 3.3 V, as required.

The PCI1225 is compliant with the PCI Local Bus Specification 2.2, and its PCI interface can act as either a PCI master device or a PCI slave device. The PCI bus mastering is initiated during 16-bit PC Card DMA transfers or CardBus PC Card bridging transactions. The PCI1225 is also compliant with the latest PCI Bus Power Management Interface Specification.
