PD6710/’22

ISA-to-PC-Card (PCMCIA) Controllers

Datasheet

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).

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

µA range.

Personal computer applications typically access PC Cards through a third-party socket/card-

services software interface. To assure full compatibility with industry-standard socket/card-

services software and PC Card applications, the register set in the PD6710 and PD6722 is a

superset of the Intel 82365SL register set.

The chips provide fully buffered PC Card interfaces, meaning that no external logic is required

for buffering signals to/from the interface, and power consumption can be controlled by limiting

signal transitions on the PC Card bus.
