| E5530 128-Bit Read-Only IDIC) for RF Identification Description The E5530 is part of a closed coupled identification system. It receives power from an RF transmitter which is coupled inductively to the IDIC. The frequency is typically 100 to 450 kHz. Receiving RF, the IDIC responds with a data stream by damping the incoming RF via an internal load. This damping-in-turn can be detected by the interrogator. The identifying data are stored in a 128 bit PROM on the E5530, realized as an array of laserprogrammable fuses. The logic block diagram for the E5530 is shown in figure 2. The data are output bitserially as a code of length 128, 96, 64 or 32 bits. The chips are factory-programmed with a unique code.

The transition from the last bit to bit 1 of the next sequence occurs without interruption. Data is transmitted by damping the incoming RF signal by an internal load. This load changes are detected by the reader station. Different kinds of modulation and bitrates are optionally available. There are four modulation methods available which can be selected by fuses. The corresponding timing diagram is shown in figure 5. FSK Modulation Logical data "1" and "0" are represented as two different frequencies of damping. The frequency for "1" is RF divided by 10, a "0" divides RF by 8. PSK Modulation The external coil is damped with a carrier frequency of RF/2. A logical "1" causes (at the end of the bit period) a 180 phase shift on the carrier frequency, while a logical "0" causes no phase shift. Rectifier For internal power supply, an on-chip bridge rectifier is used which consists of two diodes and two n-channel transistors. A Zener diode, which protects the circuit against overvoltage on the coil inputs, and a smoothing capacitor for the internal supply are also provided. Biphase Modulation Logical "1" produces a signal which is the same as the internal bitclock. A logical "0" produces no signal change in the middle of the bit period. Damping Load Incoming RF will be damped by the power consumption of the IC itself and by an internal load, which is controlled by the modulator. The loads are p-channel transistors connected between VDD and the coil inputs. The IDIC includes mask options for the load circuit: single-side, double-side and alternate-side modulation. Manchester Modulation A logical "1" causes a rising edge in the middle of a bit period (i.e., switch damping off), while a logical "0" causes a falling edge (i.e., switch damping on). A combination of Biphase- and FSK-modulation is also optionally available. The available combinations between the modulation types and the bitrates are shown in table "Transmission Options".

Transmission options Customer ID Code Selection In general the customer may choose any ID code suitable to his application. To avoid code duplication, TEMIC Semiconductors will define a fixed header * i.e, the first 8 bits of the code * for each customer.

The format has to comply to the following rules: - The ID code file is a plain ASCII text file. - The code files should be compressed. Please make self extracting files. - The code files are used in alphabetical order of their file names (including letters and numbers). Used - i.e. programmed - code files are discarded. - Each line of the code file must contain one ID code for one IC. - The code is in hexadecimal format. The code may contain spaces for better readability. Reading Distances The E5530 is able to operate from very weak fields. Nevertheless, there are some general rules which influence the achievable reading distance. D Best results are accomplished when the transponder points towards the reader coil. D The transponder should not be embedded in metal, which will reduce the applicable magnetic field and thus the reading distance. D The strength of the generated magnetic field and the sensitivity of the demodulator are the most important factors for a good reading distance. E6 00 00 00 10 2D 72 5D Header 56-bit ID code - The code line is exactly as long as the selected code length (e.g. 64 bits 16 hex numbers). - The line must end with a carriage return. - The first 8 bits are fixed, this is the unique customer header which is defined by TEMIC Semiconductors. - Each hexadecimal code entry must be preceded by a decimal serial number. Serial number and code must be separated by a space. - The serial number has to be unique and is upcounting to avoid double programming. - The series numbers of two consecutive files (file name!) has to count up too for proper linking. Figure 6. Example for a 64-bit code The identification code is transmitted continously. After the RF field is applied, the E5530H-232 starts with the first bit (MSB) of the header byte 'E6hex' ('1110 0110'), followed by a unique 56-bit serial number. No checksum is included in this sample code. Pulsing the RF field may reduce the synchronization task as the first byte transmitted is known already (i.e., E6hex). This is even feasible, if the first bit may be lost due to reader synchronization problems. 4 (8) Rev.A4, 24-May-00 E5530 FILE0000.TXT 00001 00002 00003 ... ... 12345 E65F34E25801904F E634E25801904FAA E6910AG7000010FE Code file File name Samples TEMIC Semiconductors supplies E5530 samples, which are set to Manchester modulation at RF/32 with a 64-bit ID code (order code: E5530H-232 S8).

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. TEMIC Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. TEMIC Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use TEMIC Semiconductors products for any unintended or unauthorized application, the buyer shall indemnify TEMIC Semiconductors against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
