CL-PD6833

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.
