1.0 Introduction

The PD6710, PD6722, and PD6729 are single-chip PCMCIA interface controllers capable of controlling one or two PCMCIA or compact Flash sockets, respectively. They are designed fo r us e in embedded applications and notebook systems where reduced form factor and low power consumption are critical design objectives.

Current typical application examples include:

■ Routers ■ Integrated access devices

■ Access network servers ■ DSLAMs

■ PBXs ■ Terminal servers

■ Vending machines ■ Point of Sale terminals

■ Portable h andheld systems ■ Navigation systems

■ Data acquisition systems ■ Measurement equipment

■ Settop boxes

With the PD6710, a complete single-socket PCMCIA solution with power-control circuitry can occupy less than 1.5 square inches (10 square centimeters) of board space. Similarly, with the PD6722 and PD6729, a complete dual-socket PCMCIA solution with power-control circuitry can occupy less than 2 square inches (13 square centimeters) of board space.

The PD67XX controllers are completely compatible with the standards of PCMCIA (Person a l Card Memory International Association) Release 2.0 Standard as well as JEIDA (Japan Electronic Industry Development Association) Version 4.1 Standard (PD6729 is compliant with the PCI 2.1 Specification. The PD67XX controllers also offer special power-saving features such as Automatic Low-power Dynamic Mode and Suspend Mode. Both controllers are true mixed-voltage devices that can operate at +5 volts, +3.3 volts, or a combination of these at various interfaces. The controllers have full internal buffering and requir e no additional circuitry to interface to the ISA (or ISA-like) Bus for the PD6710 and PD6722, and the PCI Bus for PD6729, or to PCMCIA sockets.

Note: In this document, PD67XX represents the PD6710, PD6722, and PD6729.
