5.18 Winbond 83627 Super-I/O
A Winbond 83627HG Super-I/O controller is connected module's LPC bus on ETXexpress® miniBaseboard. The COM
Express™ miniBaseboard Type 2 includes a Winbond 83627HFJ Super-I/O. Both LPC-I/O controller offers legacy
interfaces like RS232 and parallel ports additionally to temperature, FAN and voltage monitoring features.
Modules with onboard Super-I/O may conflict with the standard LPC-I/O address 2Eh. Therefore it's possible on
ETXexpress® miniBaseboard to change the LPC address to 4Eh by closing jumper J25.
On COM Express™ miniBaseboard Type 2 the configuration jumpers J75 and J79 allow disabling the KBC or holding the
Super-I/O in reset to simulate a legacy free backplane.
