R EM MICROELECTRONIC - MARIN SA EM4100 Read Only Contactless Identification Device Description The EM4100 (previously named H4100) is a CMOS integrated circuit for use in electronic Read Only RF Transponders. The circuit is powered by an external coil placed in an electromagnetic field, and gets its master clock from the same field via one of the coil terminals. By turning on and off the modulation current, the chip will send back the 64 bits of information contained in a factor y preprogrammed memory array. The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code on each chip. The EM4100 has several metal options which are used to define the code type and data rate. Data rates of 64, 32 and 16 periods of carrier frequency per data bit are available. Data can be coded as Manchester, Biphase or PSK. Due to low power consumption of the logic core, no supply buffer capacitor is required. Only an external coil is needed to obtain the chip function. A parallel resonance capacitor of 74 pF is also integrated.

The AC voltage is rectified in order to provide a DC internal supply voltage. When the last bit is sent, the chip will continue with the first bit until the power goes off. Full Wave Rectifier The AC input induced in the external coil by an incident magnetic field is rectified by a Graetz bridge. The bridge will limit the internal DC voltage to avoid malfunction in strong fields. Clock Extractor One of the coil terminals (COIL1) is used to generate the master clock for the logic function. The output of the clock extractor drives a sequencer. Sequencer The sequencer provides all necessary signals to address the memory array and to encode the serial data out. Three mask programmed encoding versions of logic are available. These three encoding types are Manchester, biphase and PSK. The bit rate for the first and the second type can be 64 or 32 periods of the field frequency. For the PSK version, the bit rate is 16. The sequencer receives its clock from the COIL1 clock extractor and generates every internal signal controlling the memory and the data encoder logic. Data Modulator The data modulator is controlled by the signal Modulation Control in order to induce a high current in the coil. In the PSK version, only COIL2 transistor drives this high current. In the other versions, both coil1 and coil2 transistors drive it to Vdd. This will affect the magnetic field according to the data stored in the memory array. Resonance Capacitor This capacitor can be trimmed in factory by 0.5pf steps to achieve the absolute value of 74pf typically. This option, which is on request, allows a smaller capacitor tolerance on the whole of the production.

Memory Array for PSK encoding ICs The PSK coded IC's are programmed with odd parity for P0 and P1 and always with a logic zero. The parity bits from P2 to P9 are even. The column parity PC0 to PC3 are calculated including the version bits and are even parity bits. Code Description Manchester There is always a transition from ON to OFF or from OFF to ON in the middle of bit period. At the transition from logic bit “1” to logic bit “0” or logic bit “0” to logic bit “1” the phase change. Value high of data stream presented below modulator switch OFF, low represents switch ON (see Fig. 6). Biphase Code At the beginning of each bit, a transition will occur. A logic bit “1” will keep its state for the whole bit duration and a logic bit “0” will show a transition in the middle of the bit duration (see Fig. 7). PSK Code Modulation switch goes ON and OFF alternately every period of carrier frequency. When a phase shift occurs, a logical "0" is read from the memory. If no shift phase occurs after a data rate cycle, a logical "1" is read (see Fig. 8). 1 1 1 8 version bits or customer ID 32 data bits 1 1 1 D00 D01 D10 D11 D20 D21 D30 D31 D40 D41 D50 D51 D60 D61 D70 D71 D80 D81 D90 D91 PC0 PC1 1 D02 D12 D22 D32 D42 D52 D62 D72 D82 D92 PC2 1 D03 D13 D23 D33 D43 D53 D63 D73 D83 D93 PC3 1 P0 P1 P2 P3 P4 P5 P6 P7 P8 P9 S0 9 header bits 10 line parity bits 4 column parity bits The header is composed of the 9 first bits which are all mask programmed to "1". Due to the data and parity organisation, this sequence cannot be reproduced in the data string. The header is followed by 10 groups of 4 data bits allowing 100 billion combinations and 1 even row parity bit. Then, the last group consists of 4 event column parity bits without row parity bit. S0 is a stop bit which is written to "0" Bits D00 to D03 and bits D10 to D13 are customer specific identification. These 64 bits are outputted serially in order to control the modulator. When the 64 bits data string is outputted, the output sequence is repeated continuously until power goes off.
