Pin diagrams ( XC9536-PC44/XC9572-PC44 )

The figure on the left is the top view of CPLD of 44 pins.
The following item is used to know the position of the pin.

*The direction of the printed name.
*A corner in the upper left is shaved.

A pin numbering is counterclockwise given from the center of the line in the topside.

Note is necessary to the pin arrangement by the Function Block and the macrocell because it a little irregular-ly.

In case of XC9536-PC44, the macrocells which corresponds to the input/output pins are 34 macrocells in the 36 macrocells.
In case of XC9572-PC44, they are 34 macrocells in the 72 macrocells.
The macrocells which don't correspond to the input/output pins can be used only in the logic circuits inside.
