Using Pi Option; Sio Chip Soldered On Pcb; Sam Card Connection - Elatec TWN4 MultiTech Core Manual

4 Using PI Option

4 Using PI Option
To use the PI Option, e.g. to read the PAC bits from an iCLASS transponder, a SIO processor is needed.
This can be either a SIO chip which is soldered directly on a PCB or a SAM card incorporating the SIO
processor.

4.1 SIO Chip soldered on PCB

The SIO processor has to be added to the design of the mainboard. The chip can be connected either to
SAM1 or SAM2 of the TWN4 Core Module.
Recommended schematic:

4.2 SAM Card Connection

A SAM socket has to be added to the design of the mainboard. The SAM socket can be connected either
to SAM1 or SAM2 of the TWN4 Core Module.
Following SAM sockets are recommended:
• Molex 47388-2001
• Molex 47308-0001
