PRELIMINARY DATA SHEET v3.1
PIN INFORMATION
2.2
Pin Description Conventions
The following conventions apply to the pin description tables in
Section 2.3
:
G
A dash (-) at the beginning of a pin name indicates an active-low signal for the PC Card bus.
G
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 CL-PD67XX.
G
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.
G
A pin name ending in bracketed digits separated by a colon [n:n] indicates a multi-pin bus.
G
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
G
The quantity (Qty.) column indicates the number of pins used (per socket where applicable).
G
The I/O-type code (I/O) column indicates the input and output configurations of the pins on the
CL-PD67XX.The possible types are defined below.
G
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 CL-PD67XX. The possible types are defined below.
I/O Type
Description
I
Input pin
O
Constant-driven output pin
I/O
Input/output pin
O-OD
Open-drain output pin
O-TS
Tristate output pin
-PU
An internal pull-up resistor is
present
GND
Ground pin
PWR
Power pin
Power Type
Output or Pull-up Power Source
1
+5V: powered from a 5.0-volt power
supply in most systems (see descrip-
tion of +5V pin in
Table 2-5
)
2
A_SOCKET_VCC: powered from the
Socket A V
CC
supply connecting to PC
Card pins 17 and 51 of Socket A
3
B_SOCKET_VCC: powered from the
Socket B V
CC
supply connecting to PC
Card pins 17 and 51 of Socket B
4
ISA_VCC: powered from the ISA bus
power supply
5
CORE_VDD: usually powered from the
lowest available power supply for low-
est power consumption, which in most
systems is 3.3 volts
NOTE:
All pin inputs are referenced to CORE_VDD, independent of their output supply voltage.
G
The drive-type (Drive) column describes the output drive-type of the pin (see DC specifications in
Chapter 15
for more information). Note that the drive type listed for an input-only (I) pin is not applicable (–).
