CL-PD6730 PCI PCMCIA Controller
The CL-PD6730 is a single-chip PC Card host adapter solution capable of controlling two fully
independent PC Card sockets. The chip is compliant with PC Card Standard, PCMCIA 2.1, and
JEIDA 4.1 and is optimized for use in notebook and handheld computers where reduced form
factor and low power consumption are critical design objectives.
The CL-PD6730 chip employs energy-efficient, mixed-voltage technology that can reduce system
power consumption by over 50 percent. The chip also provides a Suspend mode and an automatic
Low-Power Dynamic mode, which stop transactions on the PC Card bus, stop internal clock
distribution, and turn off much of the internal circuitry.
PC applications typically access PC Cards through the socket/card-services software interface. To
assure full compatibility with existing socket/card-services software and PC Card applications, the
register set in the CL-PD6730 is a superset of the CL-PD6729 register set.
The chip provides fully buffered PC Card interfaces, meaning that no external logic is required for
buffering signals to/from the interface, and power consumption can be controlled by limiting signal
transitions on the PC Card bus.
