Hardware design
This chapter gives basic advise, that is required in order to load UNIGATE
®
IC into your own
hardware designs. In the following all ports of UNIGATE
®
IC are described in detail.
3.1
Ports
UNIGATE
®
IC features 32 pins in its layout as a DIL 32 component. Pin 10 -12 and 21 - 23 as
well are not wired due to the electrical isolation. The exact mechanical dimensions can be taken
In the layout boreholes for ALL 32 pins have to be planned.
