PD6729

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. www.DataSheet4U.com As of May 2001, this document replaces the Basis Commun...
