LPC Super- I/O Interface
In a modern system, legacy ports as PS/2 keyboard/mouse, COM1/2 and LPT have been replaced
by USB and Ethernet connectivity. The 1.4MB floppy disk drive has been overcome by CD-RW or
DVD-RW optical drives, attached to the IDE connector, or USB memory sticks. Hence, the CC3-
CAJUN is virtually provided with all necessary I/O ports. However, for compatibility purposes the
CC3 is additionally equipped with a simple Super-I/O chip, for optional rear I/O of PS/2
keyboard/mouse and COM1 (TTL level only) across the J2/P2 CPCI connector. The Super-I/O
controller resides on the local LPC bus (LPC = Low Pin Count interface standard), which is a
serialized ISA bus replacement, controlled by the ICH2 hub.
As an alternative, EKF offers the CC6-ACID, an expansion module to the CC3-CAJUN, featuring
all classic Super-I/O functionality. The CC6-ACID is a 3U Eurocard, with an either 8HP (double)
or 4HP (single) width front panel. Access to the connectors COM1/2, LPT, mouse, keyboard is
given directly from the front panel. On board connectors are provided for FDD, MIDI/Gameport,
and cooling fans. Optionally, the CC6 is available with an on-board 2.5-inch hard disk drive. The
CC6-ACID connects to the CC3-CAJUN across the connectors PLPC and PIDE. The CC6-ACID can
be attached either to the top of the CC3-CAJUN or to the bottom (bottom attachment restricted
to the 4HP version of the CC6-ACID).
The photo above (left) shows the bottom attachment of the CC6-ACID. The boards are fixed
together by the LPC connector and the IDE connector, and in addition by a bracket which bolts
together both front panels. The right image shows the top attachment of the CC6-ACID.
The photo above (left) shows the CC3-CAJUN and CC6-ACID connected by the LPC interface. The

Together, the CC3-CAJUN and the CC6-ACID form an ultra-compact, complete desktop
functionality, industrial grade computer system.
