PCMCIA Host Adapters
OVERVIEW
The CL-PD6710 and CL-PD6722 are single-chip
PCMCIA host adapter chips capable of controlling
one (CL-PD6710) or two (CL-PD6722) PCMCIA
sockets. The chips are fully PCMCIA-2.1 and JEIDA-
4.1 compliant and are optimized for use in notebook
and handheld computers where reduced form factor
and low power consumption are critical design objec-
tives. With the CL-PD6710, a complete PCMCIA
solution with power-control logic can occupy as little
as 1.5 square inches (excluding the connector). The
CL-PD6722 enables a complete dual-socket PCM-
CIA solution with power-control logic in less than 2
square inches (excluding connectors).
The CL-PD6710 and CL-PD6722 chips employ
energy-efficient mixed-voltage technology that can
reduce system power consumption by over 50 per-
cent. The chips also provide a Suspend mode, which
stops the internal clock, and an automatic Low-power
Dynamic mode, which stops transactions on the
PCMCIA bus, stops internal clock distribution, and
(cont.)
turns off much of the internal circuitry.
