1 Introduction
1 Introduction
TWN4 MultiTech Mini is a module to be integrated on custom PCB. It has a built-in HF antenna and subset
of IOs compared to TWN4 Core Module. TWN4 Mini Reader is currently available as version TWN4 Mini
Reader MIFARE NFC.

3 Connectors
3 Connectors
The TWN4 Mini Reader has two on-board single row headers with 8 positions each. The pins of these two
connectors are together enumerated from 1 to 16.
• Single row header
• Pitch 2.54mm
• Pin shape square 0.635mm
Pin Pin Name Function
1 RESET- Low active TTL input with internal pull-up resistor for hard re-
set.
2 PWRDWN- Low active TTL input with internal pull-up resistor for turning
off the voltage regulator.
3 GND Ground
4 VIN Unregulated input to on-board voltage regulator
5 RXD- Low active TTL input with internal pull-up resistor of asyn-
chronous RXD to COM1.
6 TXD- Low active TTL output (push/pull) of asynchronous TXD from
COM1.
7 Res. Reserved for future use (intended for SCK from SPI host in-
terface).
8 Res. Reserved for future use (intended for SS- from SPI host inter-
face).
9 VCC Internaly regulated 3.0V power supply. To be used for SAM1.
10 SAM_IO I/O line for SAM1.
11 GPIO3 GPIO3, I/O pin for general purposes.
12 GPIO2 GPIO2, I/O pin for general purposes.
13 GPIO1 GPIO1, I/O pin for general purposes.
14 GPIO0 GPIO0, I/O pin for general purposes.
15 SAM_CLK Clock output for SAM1
16 SAM_RST Reset output for SAM1

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 shall be connected to the
SAM-pins of the TWN4 Mini Reader.
Recommended schematic:
4.2 SAM Card Connection
A SAM socket has to be added to the design of the mainboard. The SAM socket shall be connected to the
SAM-pins of the TWN4 Mini Reader.
Following SAM sockets are recommended:
• Molex 47388-2001
• Molex 47308-0001
Recommended schematic:
