General The transponder is the mobile part of the closed coupled identification system (see Figure 1-1), whereas the read/write base station is based on the U2270B or on discrete solutions, and the read/write transponder is based on the e5561A IDIC. The transponder is a plastic-cube device consisting of the following parts: • The transponder antenna, with a tuned LC-circuit • Read/write IDIC (e5561A) with EEPROM 3. Transponder Antenna The antenna consists of a coil and a capacitor for tuning the circuit to the nominal carrier fre- quency of 125 kHz. The coil has a ferrite core to improve the read, write and programming operation distances. 4. Read/Write Crypto Identification The e5561A is a member of the Atmel®'s contactless IDentification IC (IDIC) family, which are used in applications where information has to be transmitted without contacts. The IDIC is con- nected to a tuned LC circuit for power supply and bidirectional data communication (Read/Write) to a base station. The on-chip non-volatile memory of the 320-bit EEPROM (10 blocks, 32 bits each) can be read and written blockwise by a read/write base station, e.g. based on the U2270B. Up to four blocks consisting of the user programmable ID code, the crypto key and configurations are stored in six blocks. The crypto key and the ID code can be individually protected against overwriting. The typical operational frequency of the TK5561A-PP is 125 kHz. Two data bit rates are pro- grammable: Rf/32 and Rf/64. During the reading operation the incoming RF field is dampened bit-wise by an on-chip load. This AM-modulation is detected by the field generating base station unit. Data transmission starts after power-up with the transmission of the ID code and continues as long as the TK5561A-PP is powered. Writing is carried out by means of Atmel's patented writing method. To transmit data to the TK5561A-PP the read/write base station has to interrupt the RF field for a short time to create a field gap. The information is encoded in the number of clock cycles between two subsequent gaps. See the e5561A data sheet for detailed information of the IDIC. |
