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
μ
A range.
