OVERVIEW
The CL-PD6832 is a single-chip CardBus host
adapter solution capable of controlling two fully
independent CardBus sockets. It is compliant with
PCI 2.1, PCMCIA 2.1, PC Card Standard, and
JEIDA 4.1. The CL-PD6832 is optimized for use in
notebook and handheld computers where reduced
form factor and low power consumption are critical
design objectives.
To minimize system power consumption, the
CL-PD6832 employs energy-efficient, mixed-volt-
age technology. The device also provides a Hard-
ware Suspend mode that reduces much of the
power consumption.
The CL-PD6832 allows easy translation of incoming
memory commands to PC Card 16 I/O commands
for processors with memory commands only. It
enables these processors to use PC Card I/O
devices with fully programmable windows. All
CL-PD6832 control registers can either be memory-
(cont.)
or I/O-mapped.
