EM4005 EM4105 EM MICROELECTRONIC - MARIN SA ISO 11'784 / 11'785 Compliant Read Only Contactless Identification Device Description Features The EM4005/EM4105 (previously named H4005/H4105) is a CMOS integrated circuit intented 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. The other coil terminal is affected by the modulator. By turning on and off the modulation current, the chip will send back the 128 bits of information contained in a factory pre-programmed 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. Due to the 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 75 pF is also integrated.

The AC voltage is rectified in order to provide a DC internal supply voltage. When the DC voltage is sufficient the chip sends data continuously. 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. Data Encoder The data is coded according to the FDX-B scheme. 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 (refer to fig. 4). The FDX-B allows an advance of up to 8 clocks in the ON to OFF transition. Due to its low power consumption, there is no difference in performance for the H4005 when implementing a transition advance. No clock advance is provided on the standard version. Data Modulator The data modulator is controlled by the signal Modulation Control in order to induce a high current on COIL2 terminal when this signal is at logic "0". This will affect the magnetic field according to the data stored in the memory array. Sequencer The sequencer provides all necessary signals to address the memory array and to encode the serial data out. The data rate is set to 32 clocks per bit. Memory The memory contains 128 bits laser programmed during manufacturing according to a customer list of codes. The bits are read serially in order to control the modulator. The 128 bits output sequence is repeated continuously until power goes off.

The header is followed by the Identification code which is composed of 64 bits organised in 8 blocks of 8 bits. Each block of 8 bits is trailed by a control bit set to logic "1" to prevent that the header is reproduced in the data. Bit 64 is transmitted first. Bit 1 is a flag for animal "1" or non-animal "0" application. Bits 2-15 are a reserved code for future use. Bit 16 is a flag for additional data block "1" or no additional data block "0".
