PRELIMINARY DATA SHEET v3.1

CL-PD6710/’22

ISA–to–PC-Card Host Adapters

May 1997

The chips provide fully buffered PC Card interfaces,

meaning that no external logic is required for buffer-

ing signals to/from the interface, and power con-

sumption can be controlled by limiting signal

transitions on the PC Card bus.

Personal computer applications typically access PC

Cards through a third-party socket/card-services

software interface. To assure full compatibility with

industry-standard socket/card-services software and

PC Card applications, the register set in the

CL-PD6710 and CL-PD6722 is a superset of the

Intel® 82365SL register set.
