The microcontroller activates and deactivates the transmitter and switches the receiver between the modes for the different transponders reception. HOST SYSTEM The connection to the host system (e.g. microcontroller or PC) is a serial interface on RS232 level for data transmission. 7.1.4 Additional functions of the microcontroller are controlling the standby mode of the amplifier, detection of detuned or broken antennas (antenna malfunction) and controlling of the input and output for general purpose. I/O FUNCTIONS One line of the HTRM800 is wired as input from e.g. a switch and one line as output to drive a LED. 2001 Oct 04 MICROCONTROLLER The microcontroller is placed on the HITAG core module (see Fig.1) and processes the protocol for the communication between the transponders and the reader module. The interface signals are converted so that the transponders are able to process them and the outgoing signals from the transponders are converted into interface-compatible signals. The antenna is an important part of the HITAG long range system. The antenna must provide energy and data transmission between the reader module and transponder. 7.1.3 Reader module hardware 6 Philips Semiconductors Product specification HITAG long range reader module hardware 7.3.2 HTRM800 family reader module and transponder the located disturbers are eliminated. The command StartFFT should be executed as often as the application allows. INTERFACE MICROCONTROLLER TO HOST The device communicates with the host system via a serial interface using a baud rate of 9600 baud. Data transfer details are: 1 start bit, 8 data bits, 1 stop bit, no parity bit and the least significant bit is sent first. Remarks: 1. The DSP is able to suppress up to two harmonic electromagnetic disturbances Version HTRM800/AED has an integrated RS232 level driver. Version HTRM800/CED is wired with an RS485 level driver and version HTRM800/EED is wired with a CMOS level driver. 2. During FFT is running (about 110 ms) communication with a transponder is not possible. 7.3.7 7.3.3 TRANSMITTING PART The reader module contains some filtering circuits which supply all parts of the reader module with the required voltages. Nevertheless some requirements are to be fulfilled by the external power supply. This means the maximum ripple of the supply voltages must not exceed the values specified in Chapter 8. For transmitting power and data to the transponder a 125 kHz sine signal is switched by the microcontroller and amplified. The amplifier is designed as a current source. A voltage limiter is used to clamp the output voltage of the amplifier during the decay and transient phases of the sine signal. 7.3.8 7.3.4 RECEIVING PART 7.3.9 DIGITAL SIGNAL PROCESSING UNIT 7.3.10 BEHAVIOUR WITH HITAG 2 TRANSPONDERS If several HITAG 2 transponders arrive simultaneously within the communication field of the antenna of a HTRM800, the ‘stronger’ transponder (the nearer one) takes over or - under special circumstances - no communication takes place. If the transponders arrive in the field one after the other, communication is established with the first one, all the other transponders are ignored. This ensures that no two (or several) HITAG 2 transponders will ever be processed (above all written to!) accidentally at the same time. By muting a selected HITAG 2 transponder (HALT mode) another HITAG 2 transponder that is to be found in the communication field of the antenna can be recognized. PERIODIC DISTURBERS There are a couple of possible sources for disturbances for a 125 kHz system like HITAG. The HTRM800 is designed to handle this problem and achieve optimal performance under worst conditions. Long wave transmitters, other 125 kHz systems and PC monitors are examples for periodic disturbers which can be relevant for 125 kHz systems. To eliminate these disturbers the digital signal processing unit is used. After the command StartFFT is sent to the reader module a Fast Fourier Transformation (FFT) is started to locate periodic disturbers. After about 110 ms this calculation is finished and for the following communication between 2001 Oct 04 BEHAVIOUR WITH HITAG 1 TRANSPONDERS If several HITAG 1 transponders arrive simultaneously within the communication field of the antenna of a HTRM800, all the transponders (theoretically up to 232) within the communication field of the antenna can be read and written simultaneously. Because of the mutual influence of the transponder coils - they detune each other if there are too many too close to each other - the number of the transponders that can be operated simultaneously is limited. The receiving part of the reader module includes bandpass filters which attenuate disturbances (3 dB attenuation at 105 and 145 kHz). For disturber frequencies near the 125 kHz (e.g. harmonics of the line frequency of PC monitors, long wave transmitters) a fourier transformation is used to recognize harmonic disturbers and to eliminate their influence. The DSP is also responsible for separating the responses of different transponders during anticollison cycles (multiple transponder operation). 7.3.6 STANDBY MODE The HTRM800 offers a software controlled standby mode. This mode can be activated and deactivated by the host system. During the standby mode the amplifier is turned off and the power consumption decreases drastically. After filtering and demodulation of the amplitude modulated signal received from the transponder, the received data is converted and passed to the Digital Signal Processing (DSP) unit for further processing. 7.3.5 VOLTAGE REGULATING UNIT 7 Philips Semiconductors Product specification HITAG long range reader module hardware 7.4 HTRM800 family Postal approval The following configuration is in compliance with the European telecommunication standards: The postal approval can only be granted for final products, not just for components like the HTRM800. But this reader module is designed in a way that it is possible to get the postal approval for a system including the HTRM800. • Reader module HTRM800 • Power supply according to the recommendations (transformer type) • Antenna: 50 × 70 cm, number of turns N = 26 and inductivity L = 1.2 mH. Electromagnetic emissions comply with the guidelines in FTZ 17 TR 2100, ETS 300 330 and ETS 300 683. Electromagnetic immunity complies with the guidelines in ETS 300 683.

Operating security The following mechanisms ensure the operation security of the HITAG system: • Anticollission mode 7.5.2 • Monitoring the supply voltage The supply voltage is controlled by a watch dog circuit which triggers a system reset if the supply voltage of the core module drops below 4.75 V or if the microcontroller fails. • Antenna rupture and short circuit. 7.5.1 ANTICOLLISION MODE Anticollision mode in long range applications permits you to process several HITAG 1 transponders simultaneously. Theoretically up to 232 HITAG 1 transponders can be processed simultaneously. In practice this number is limited, because of the mutual influence of the transponders. They detune each other, if there are too many too close to each other. In long range applications using HITAG 2 transponders, only one transponder is handled even if there are several transponders within the communication field of the antenna. In this case either no communication takes place or the ‘stronger’ or closer transponder takes over. 2001 Oct 04 MONITORING THE SUPPLY VOLTAGE 7.5.3 ANTENNA RUPTURE AND ANTENNA SHORT-CIRCUIT The HTRM800 does not get permanently damaged in case of an antenna rupture or a brief antenna short-circuit. The detection of detuned or broken antennas (antenna malfunction) is possible. 8 Philips Semiconductors Product specification HITAG long range reader module hardware 7.6 HTRM800 family Security considerations To make use of cryptography for HITAG 2 transponders you need: Developing the HITAG system special consideration was given to aspects of security. The following items represent the fundamental framework of the security concept: • A key which is used to initialize the crypto block using HITAG 2 in crypto mode • Passwords which are used for authentication for HITAG 2 in password mode. • Cryptography • Mutual authentication The transponders and the HTRM800 are provided with identical transport keys and transport logdata so that you can start operating them right away (see Table 2). • Password verification • Cyclic Redundancy Check (CRC). 7.6.1 In order to offer our OEM clients high flexibility, the configuration of the transponder memory, password, keys and logdata can be changed. We strictly recommend to rigorously restrict these possibilities for the end customers (by setting the configuration page to read only, setting password, keys and logdata to neither read nor write). DATA PRIVACY The use of cryptography (stream cypher), mutual authentication, and password verification prevents monitoring and copying the data channel. Therefore, the area of the transponder that only can be accessed enciphered is called ‘secret area’. To make use of cryptography for HITAG 1 transponders you need: • Keys to be used for initializing of the crypto block • Logdata to be used for mutual authentication.

MGU420 Product specification A-A HTRM800 family 5.56 Philips Semiconductors Product specification HITAG long range reader module hardware HTRM800 family 10 APPLICATION INFORMATION 10.2 10.1 In order to be able to operate two systems side by side without negative influence on communication ranges, you must place the antennas at a minimum distance. To keep this distance low, magnetic shielding must be realized. This topic is handled in detail in application note “Antenna Design for the HITAG Long Range System”. Metallic environment and interferences The communication range is impaired by metallic environment and electromagnetic interferences (e.g. monitors and keyboards). Therefore, you should keep a distance of at least one time the antenna diameter to metallic surfaces or loops as well as to electromagnetic interferences. If this is not possible, you have to take preventive measures such as using ferrites or shielding for transponder and antenna. 10.3 External power supply Instead of a transformer type supply unit (see Fig.5), a switching frequency power supply unit can be used alternatively. The switching frequency must be in the range from 165 to 210 kHz (overtemperature, load and production).

The antenna must provide energy and data transmission between the reader module and transponder. Therefore, you should be particularly careful when implementing the antenna in order to achieve optimum results. • Power supply voltage not in the specified range • Serial interface not connected correctly • Interference received by the antenna because of an external noise source (e.g. monitor, keyboards); the remedial measure is to remove the antenna from the interfering area and use the command StartFFT The equivalent circuit of the antenna is shown in Fig.6. • Connecting cables of the antenna changed by mistake The requirements of the antenna coil are: • Antenna is mounted in metal environment; the remedial measure is to mount a non-metal space keeper between the antenna and the metal • Quality factor: Q = 30 to 60 X Q = ------s where Rs • Antenna is not designed following the antenna design instructions Xs = effective series reactance • Inductance of the antenna is not in the specified range Rs = effective series resistance • Quality factor of the antenna is not in the specified range. • Inductance: L = 400 to 1200 µH. handbook, full pagewidth coax cable VOLTAGE LIMITER antenna C Vo Rs Xs HTRM800 MGU421 Fig.6 Basics of the long range antenna. 2001 Oct 04 13 Philips Semiconductors Product specification HITAG long range reader module hardware 10.5.2 HTRM800 family 10.5.7 RECOMMENDED ANTENNA CABLE AND LENGTH The length of the antenna cable should be limited with five meters. In case of longer cables a type with low capacitance and resistance must be used. For standard applications a 50 Ω coaxial cable is recommended and a 75 or 95 Ω coaxial cable for special applications. 10.5.3 The following list is a summary about HITAG long range antennas: • Philips lays high emphasis on the research of antenna development • The choice of various antenna shapes (the electrical parameters) is characteristic to 125 kHz systems TUNING OF THE ANTENNA CURRENT • The knowledge is transferred to Philips customers, in order to enable them to design and build antennas which fit best for the particular applications (antenna training) Potentiometer R72 (see Fig.2) is used to tune the current driven through the antenna. The default setting is 200 mA. It is not customary to change this value. However, if you want to change the current for a special application, it should be noted that Vo(peak) < 10 V. 10.5.4 • Solutions can be found for almost every environmental scene (metal, periodic disturbers, special antenna shapes, etc.). TUNING OF THE ANTENNA PHASE 10.6 The signal from a transponder is delayed by the decay time of the antenna. To achieve optimal performance this signal and the digital signal processing unit of the reader module must be synchronous. Thus it is necessary to store a phase information called Bit Clock Delay (BCD), which is a function of the quality factor and the inductance (reactance) of the antenna. • The single loop antenna is used for standard arrangements • The gate antenna is used for typical access control applications such as access control during passing through the gate • The double gate antenna is similar to the gate using two rows • The antenna multiplex system is a cost efficient application, because one reader module drives many antennas and the number of multiplexed antennas is only limited by timing restrictions. HITAG ANTENNA TUNING DEVICE Especially for the HITAG product line the HITAG antenna tuning device HTOT840 was designed. This tuning device can be used for tuning long range and proximity antennas. 10.5.6 By changing the arrangement of the antenna, the total system performance and reliability can be significantly improved. As an example: building gate antennas with opposite magnetic orientation leads to a very reliable system. ANTENNA MALFUNCTION INDICATION If the antenna is broken or badly detuned, the antenna overload bit is set. This bit can be read by the host system via the serial interface by using the command ReadLRStatus. 2001 Oct 04 Antenna arrangements Various arrangements are suitable for different applications (see Fig.6): The default setting is 7 which is suitable in most of the cases. Apart from that, the user is able to change the BCD value. The reader module includes a non volatile memory (EEPROM) to store the bit clock delay. To load the BCD value to the reader module the command SetBCD is used. 10.5.5 ADDITIONAL REMARKS 14 Philips Semiconductors Product specification HITAG long range reader module hardware HTRM800 family handbook, full pagewidth HTRM800 HTRM800 single loop antenna gate antenna HTRM800 HTRM800 antenna multiplex double gate multiplex MGU422 Fig.6 Possible arrangements of antennas. 11 SURVEY OF REFERENCED DOCUMENTS CATEGORY TITLE Data sheet “HTCM400, HTRM440 Family, HTRM800 Family HITAG Interface Protocol Reader - Host” Application note “Antenna Design for the HITAG Long Range System” 2001 Oct 04 15 Philips Semiconductors Product specification HITAG long range reader module hardware HTRM800 family 12 DATA SHEET STATUS DATA SHEET STATUS(1) PRODUCT STATUS(2) DEFINITIONS Objective data Development This data sheet contains data from the objective specification for product development.
