The CL-PD6710 and CL-PD6722 are single-chip PC Card host adapter solutions capable of controlling one (CL-PD6710) or two (CL-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 notebook and handheld computers where reduced form factor and low power consumption are critical design objectives. With the CL-PD6710, a complete PC Card solution with power-control logic can occupy less than 1.5 square inches (excluding the socket connector). With the CL-PD6722, a complete dual-socket PC Card solution with power-control logic can occupy less than 2 square inches (excluding socket connectors). The chips employ energy-efficient mixed-voltage technology that can reduce system power consumption by over 50 percent. The chips also provide: a Low-Power Dynamic mode, which automatically stops the internal clock during periods of card inactivity; a software-controlled Suspend mode, which dramatically reduces power by disabling most of the internal circuitry and stopping data transactions to the PC Cards; and a hardware-controlled Super Suspend mode, which reduces current to the A range.
