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
from chapter 12 on page 31.
In the layout boreholes for ALL 32 pins have to be planned.
