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.

General Conventions
The following general conventions apply to this document.
Throughout this document, PD67XX means PD6710 and PD6722.
Bits within words and words within various memory spaces are generally numbered with a 0 (zero)
as the least-significant bit or word. For example, the least-significant bit of a byte is bit 0, while the
most-significant bit is bit 7.
In addition, number ranges for bit fields and words are presented with the most-significant value
first. Thus, when discussing a bit field within a register, the bit number of the most-significant bit is
written first, followed by a colon (:) and then the bit number of the least-significant bit; as in,
bits 7:0.
In this document, the names of the PD67XX internal registers are boldfaced. For example, Chip
Revision and Power Control are register names. The names of bit fields are written with initial
uppercase letters. For example, Card Power On and Battery Voltage Detect are bit field names.
Numbers and Units
The unit Kbyte designates 1024 bytes (210). The unit Mbyte designates 1,048,576 bytes (220). The
unit Gbyte designates 1,073,741,824 bytes (230). The unit Hz designates hertz. The unit kHz
designates 1000 Hz. The unit MHz designates 1,000,000 Hz. The unit ms designates millisecond.
The unit µs designates microsecond. The unit ns designates nanosecond. The unit mA designates
milliampere. The unit V immediately following a number designates volt.
Hexadecimal numbers are presented with all letters in uppercase and a lowercase h appended. For
example, 14h and 03CAh are hexadecimal numbers.
Binary numbers are enclosed in single quotation marks when in text. For example, ‘11’ is a binary
number.
Numbers not appended with an h nor enclosed by single quotation marks are decimal.
In addition, a capital letter X is used within numbers to indicate digits ignored by the PD67XX
within the current context. For example, ‘101XX01’ is a binary number with bits 3:2 ignored.
