The PD6710 and PD6722 are single-chip PC Card (PCMCIA) controller solutions capable of controlling one (PD6710) or two (PD6722) PC Card sockets. The chips are compliant with PC Card Standard, PCMCIA 2.1, and JEIDA 4.1 and are 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 PD6710, a complete PC Card solution with power-control logic can occupy less than 1.5 square inches (excluding the socket connector). With the PD6722, a complete dual-socket PC Card solution with power-control logic can occupy less than 2 square inches (excluding socket connectors).
