ISA-to-PC-Card (PCMCIA) Controllers — PD6710/’22
• An asterisk (*) at the end of a pin name indicates an active-low signal for the ISA bus or that is
a general interface for the PD67XX.
• Pins marked with a dagger (†) in the pin description tables can be switched between CMOS
and TTL input levels when CORE_VDD is powered at 5 volts. All other pins use CMOS input
levels when CORE_VDD is powered at 5 volts and TTL input levels when powered at 3.3
volts.
• A pin name ending in bracketed digits separated by a colon [n:n] indicates a multi-pin bus.
• The pin number (Pin Number) column indicates the package pin that carries the listed signal.
Note that multi-pin buses are listed with the first pin number corresponding to the most-
significant bit of the bus. For example, pin numbers 123:120, 118, 117, 115, 114, 112, 110,
108:106, 104, 103, 101, and 100 are associated with ISA Bus Address Input and Data Input/
Output pins SA[16:0] and indicate that:
— SA16 is pin 123
— SA15 is pin 122
— SA0 is pin 100
• The quantity (Qty.) column indicates the number of pins used (per socket where applicable).
• The I/O-type code (I/O) column indicates the input and output configurations of the pins on
the PD67XX.The possible types are defined below.
• The power-type code (Pwr.) column indicates the output drive power source for an output pin
or the pull-up power source for an input pin on the PD67XX. The possible types are defined
below.
