PCI-to-CardBus Host Adapter
OVERVIEW
The CL-PD6833 easily interfaces with the 8- and 16-bit
R2 PC Cards and the 32-bit CardBus PC Cards. It is
the third device to be developed in Cirrus Logic’s family
of CardBus controllers. The CL-PD6833 gives system
designers of portable, notebook, and handheld
computers the most integrated solution for their needs.
Providing high performance, low-power consumption,
and a highly compatible and flexible interface, the
CL-PD6833 enables easy functionality for PC Card
and CardBus applications such as LANs, modems,
and multimedia applications.
The CL-PD6833 is a single-chip CardBus controller
capable of controlling two independent PC Card
and/or CardBus sockets. Featuring enhanced bus
traffic management and cycle pipelining technology,
the CL-PD6833 supports transactions at the PCI
specification limit of 133 Mbytes per second. This
significantly improves the performance over previous
Cirrus Logic controllers.
