... Small package (SO14) 2. Introduction The Hitag Reader Chip HTRC110 is intended for use with transponders, which are based on the HITAG silicon (HT1ICS30 02x or HT2ICS20 02x). (E.g. the HITAG 2 stick HT2DC20 S20 may be operated with the use of the Reader Chip). In addition the IC supports other 125kHz transponder types using amplitude modulation for the write operation and AM/PM for the read operation ...

... HTRC110 Hitag Reader Chip 7. Minimum Application Circuitry The following figure shows a minimal application circuitry for the HTRC110. The reader coil L together with the capacitor C a the LC circuit are divided to safe operating levels by R the RX-pin. The two capacitors connected to XTAL1 and XTAL2 shall be the recommended values and types from the crystal’ ...

... With optimum tuning, the phase of the antenna tap voltage is 90 degrees off the antenna driver signal. Detuning of the antenna resonant circuit results in a change of this phase relationship. The HTRC110‘s built-in phase measurement unit allows the measurement of this phase relationship with a resolution of 360°/64=5.625°. This can be used to compute a sampling time that compensates the mistuning of the reader antenna ...

... Idle and Power-down Mode The HTRC110 can be switched into idle mode via setting the PD-bit and resetting the PD_MODE- bit. In this idle mode, only the oscillator and a few other system components are active also possible to switch the IC completely off. This is achieved by the power-down mode (PD=1, PD_MODE=1). Within this mode also the clock oscillator is switched off. This reduces the supply current of the HTRC110 to less than 20µ ...

... Antenna Applications” where the microcontroller and the reader com- municate via long signal lines (e.g. 1 meter). In other applications Pin 5 (MODE) has to be connected to GND. Please refer to the HTRC110 application note for a detailed description of this feature. Rev. 3.0 Page ...

... READ_TAG This command is used to read the demodulated bit stream from a transponder: After the assertion of the three command bits the HTRC110 instantaneously switches to READ_TAG-mode and transmits the demodulated, filtered and digitized data from the transponder. Data comes out and should be decoded by the microcontroller. READ_TAG-mode is terminated by a low to high transition at SCLK ...

... HTRC110 Hitag Reader Chip 9.3. WRITE_TAG This is the 3 bit short form of the previously described command WRITE_TAG_N. It allows to switch into WRITE_TAG-mode with a minimum communication time. The behaviour of the WRITE_TAG command is identical to WRITE_TAG_N with two exceptions: • WRITE_TAG-mode is entered after assertion of the 3rd command bit. ...
