PD6729
PCI-to-PC Card (PCMCIA) Controller
Datasheet
The PD6729 is a single-chip PC Card (PCMCIA) controller solution capable of controlling two
fully independent PCMCIA sockets. The chip is fully PCMCIA-2.1 and JEIDA-4.1 compliant
and is optimized for use in embedded applications and notebook/handheld/mobile computer
systems where reduced form factor and low power consumption are critical design objectives.
With the PD6729, a complete dual-socket PCMCIA solution with power-control logic can
occupy less than 2 square inches (excluding connectors).
The PD6729 chip employs energy-efficient, mixed-voltage technology that can reduce system
power consumption by over 50 percent. The chip also provides a Suspend mode, which stops the
internal clock, and an automatic Low-power Dynamic mode, which stops transactions on the
PCMCIA bus, stops internal clock distribution, and turns 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 PD6729 is a superset of the Intel
82365SL register set.
The chip provides fully buffered PCMCIA 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 PCMCIA bus.
