Pinout detail tables
Each pinout table applies to a specific interface and contains the following information:
Notes:
NO CONNECT
as a pin description means do not connect to this pin.
The 177th pin (package ball) is for alignment of the package on the PCB.
System Bus interface
Signal
The pin name for each I/O signal. Some signals have multiple function modes and are identified
accordingly. The mode is configured through firmware using one or more configuration registers.
Pin
The pin number assignment for a specific I/O signal.
U next to the pin number indicates that the pin is a pullup resistor.
D next to the pin number indicates that the pin is a pulldown resistor.
No value next to the pin indicates that the pin has neither a pullup nor pulldown resistor.
characteristics," on page 25 for an illustration of the characteristics of these pins. Use the figures
to select the appropriate value of the complimentary resistor to drive the signal to the opposite
logic state. For those pins with no pullup or pulldown resistor, you must select the appropriate
value per your design requirements.
_
An underscore (bar) indicates that the pin is active low.
I/O
The type of signal — input, output, or input/output.
OD
The output drive strength of an output buffer. The NS7520 uses one of three drivers:
2 mA
4 mA
8 mA
