User's manual 1. INTRODUCTION The EUT-002 is a smallest module in the market and highly integrated transmission module for contactless communication at RFID 13.56 MHz (HF) applications. Its simplified interface, ultra low power consumption, standard RF output port and superior performance, make it easy to integrate any device with EUT/RFID technology. The EUT-002 is a highly integrated transmission module for contactless communication at 13.56 MHz. The embedded firmware handles the ISO 14443A and MIFARE reader protocol as well as the basic FeliCa Reader protocol and the complete EUT IP-1 protocol. 1.1 Module and EUT Features ■ Module profile and Footprint 20(mm)x20(mm)x 3.2(mm) ■ EUT profile and Footprint 90(mm)x60(mm)x 8(mm) ■ Internal oscillator to connect 27.12 MHz crystal ■ Supports ISO/IEC 14443A/Mifare ■ Supports Mifare Classic encryption in reader/writer mode ■ Supports Mifare higher transfer speed communication at 212 kbit/s and 424 kbit/s ■ Supports contactless communication according to the FeliCa scheme at 212 KBaud and 424 KBaud ■ Integrated RF interface for EUT IP-1 up to 424 Kbaud ■ Ultra low power consumption ■ 2.5 - 3.6 V power supply ■ Easy Connection to Flex antenna ■ Supported High Speed Serial UART (similar to RS232 with 0 and PVDD voltage levels) host interface 1.2 Operating modes: The EUT-002 supports 2 different operating modes • Reader/writer mode for ISO14443A Mifare and FeliCa cards • EUT Mode (EUT IP-1 mode) The Analog circuitry handles the modulation and demodulation of the analog signals according to the reader /writer mode and EUT mode communication scheme. The RF level detector detects the presence of an external RF field at 13.56 MHz. The mode detector detects a MIFARE, FeliCa or EUT coding of an incoming signal in order to prepare the internal receiver to demodulate signals that are sent to the EUT-002 Module. The integrated contactless UART interface and the firmware handle the protocol requirements for the communication schemes including the RF based protocols as well as the protocols for host communication. The microcontroller with its embedded firmware allows autonomous management of communication both on the RF interface and with the host. Various host interfaces are implemented to fulfil different customer requirements.
1.2.1 Reader/Writer Operating mode The EUT-002 can act as a reader / writer for ISO14443A/MIFARE® or FeliCa cards. In the reader/ writer mode the EUT-002 EUT enables communication to a passive ISO14443A/MIFARE or FeliCa card. The EUT-002’s firmware and contactless UART handle the ISO 14443A/MIFARE and FeliCa protocol. 1.2.2 EUT MODE EUT communication differentiates between an active and a passive communication. Active EUT Mode means both the initiator and the target are using their own RF field for the communication. Passive EUT Mode means that the target answers to an initiator command in a load modulation scheme. The initiator is active i.e. generating the RF field. initiator: generates RF field @ 13.56 MHz and starts the EUT communication Target: responds to initiator commands either using load modulation scheme (RF field continuously generated by Initiator) or using modulation of self generated RF field (no RF field generated by initiator)

EUT-002 Host interfaces Two different host interface interfaces are proposed with the EUT-002 Module. One is using the USB interface and the other one use the HSU (High Speed UART: similar to RS232 with 0 and PVdd voltage levels) interface. 4.1 High speed UART interface Port Pin I/O Description IRQ 9 IO Interrupt request: Output to signal an interrupt event to the host UART_Rx 10 IO UART RX (Serial reception line of the EUT-002-UART) UART_Tx 11 IO UART TX (Serial transmission line of the EUT-002-UART) H_REQ 12 IO Request or acknowledge line from the host HSU interface default configuration is: Data bit : 8 bits Parity bit : none Stop bit : 1 bit Baud rate : 9600 bauds Data order : LSB first Baudrate: Default baudrate is 9600 bauds. EUT-002 HSU is up to 1288 kbauds. The HSU speed is changeable with SetSerialBaudrate command (command code 10h, parameter = baudrate). The host controller must send an ACK frame after reception of SetSerialBaudrate response. EUT-002 will switch to the new baudrate only after reception of this ACK frame. 4.2 How to change HSU speed in SCRTester? To activate sending of ACK frame after reception of a command, use “.config(10,01)” in SCRTester. Example of script file: .config(10,01); // SCRTester is forced to send the optional ACK 10 06; // SetSerialBaudrate (460.8 kbauds) .config(00, 460800); // Change baudrate of SCRTester to 460.8 kbaud .config(10, 00); // Deactivate the optional ACK option Handshake mode in HSU
4 lines are connected between the host controller and EUT-002 Module: UART_Rx, UART_Tx, H_REQ and IRQ. Remark: in handshake mode, IRQ line is not set low by EUT-002 when ACK frame is ready (different behaviour than standard mode + use of IRQ). 00h 01h 02h 03h 04h 05h 06h 07h 08h 9.6 kbauds 19.2 kbauds 38.4 kbauds 57.6 kbauds 115.2 kbauds230.4 kbauds460.8 kbauds921.6 kbauds1288 kbauds
5. EUT Reference Schematic We provide the EUT-002-UART pins defined and inculde EUT ambient circuit design. And highly recommend using this diagram for reference design. 6. EUT-002 EUT Layout Guide 1. If the system implementation is complex (i.e. RFID reader module is a subsystem of a greater system with other modules (Bluetooth, WiFi, micros & clocks), special considerations should be taken to ensure that there isn’t any noise coupling into the supply lines. If needed, special filtering/regulator considerations should be used to minimize or eliminate that noise in these unique systems. This will ensure optimal RFID reader performance. 2. Avoid crossing of digital lines under RF signal lines. Also, avoid crossing of digital lines with other digital lines whenever possible. If the crossings are unavoidable, 90 degree crossings should be used to minimize coupling of the lines. 3. Trace line lengths should be minimized whenever possible. Especially, the RF output path, x’tal connections, and control lines from the reader to the micro. Proper placement of the reader, micro, xtal and RF connection/connector will help facilitate this. 7.
