3.9 Electrical specifications of the application interface
Please note that the reference voltages listed in Table 14 are the values measured directly
on the MC45 module. They do not apply to the accessories connected.
If an input pin is specified for V
i,h,max
= 3.3V, be sure never to exceed the stated voltage. The
value 3.3V is an absolute maximum rating.
The Hirose DF12C board-to-board connector on MC45 is a 50-pin double-row receptacle.
The names and the positions of the pins can be seen from Figure 26 which shows the top
view of MC45.

Note: Pin numbers have changed since the first
release of this document (MC45_HD_01_v0001).
The positions of the pins are still the same.
