1 / 128 page  CL-PD6710/’22 Preliminary Data Sheet ® May 1997 Version 3.1 OVERVIEW FEATURES s Single-chip PC Card host adapters s Direct connection to ISA (PC AT) bus and one or two PC Card sockets s Compliant with PC Card Standard, PCMCIA 2.1, and JEIDA 4.1 s 82365SL-compatible register set, ExCA ™-compatible s Automatic Low-Power Dynamic mode for lowest active power consumption s Programmable Suspend mode s Hardware-enabled Super Suspend mode s Five programmable memory windows per socket and two programmable I/O windows per socket s Programmable card access cycle timing s 8- or 16-bit system bus interface s 8- and 16-bit PC Card interface support s ATA disk interface support s DMA support (CL-PD6722) s Card-voltage sense support s PC Card activity indicator s Mixed-voltage operation (3.3/5.0 V) s Single-socket interface: 144-pin VQFP for smallest form factor (CL-PD6710) s Dual-socket interface: 208-pin PQFP or VQFP (CL-PD6722) 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 Stan- dard, 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 com- plete dual-socket PC Card solution with power-con- trol logic can occupy less than 2 square inches (excluding socket connectors). The chips employ energy-efficient mixed-voltage technology that can reduce system power consump- tion by over 50 percent. The chips also provide: a Low-Power Dynamic mode, which automatically stops the internal clock during periods of card inac- tivity; 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 Sus- pend mode, which reduces current to the µA range.
