8 Additional Hardware Requirements

8.1 Programming Firmware

To program firmware to the TWN4 Nano Module, it is mandatory to have at least one of the following
connections:
• USB
• COM1
• COM2
This should be kept in mind while designing a mainboard for the TWN4 Nano Module.
For a description how to program firmware to the TWN4 Nano Module please refer to documents TWN4
AppBlaster Config Cards User Guide DocRev6.pdf for Windows and TWN4 Programming with Command
Line under Linux DocRev1.pdf for Linux.

8.2 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.

8.2.1 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 Nano Module.
Recommended schematic:

8.2.2 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 Nano Module.
