General

The transponder is the mobile part of the closed coupled identification system see Figure 1 on page 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 IDIC e5551.

The transponder is a plastic cube device consisting of the following parts
• The transponder antenna, realized as a tuned LC circuit
• Read/write IDIC e5551 with EEPROM

Transponder Antenna The antenna consists of a coil and a capacitor for tuning the circuit to the nominal carrier
frequency of 125 kHz. The coil has a ferrite core for improving the distance of read, write and programming operations.

Read/Write IDIC e5551

The read/write IDIC e5551 is part of the transponder TK5551. The data are transmitted bi-directionally between the base station and the transponder. The transponder receives power via a single coil from the RF signal generated by the base station. The single coil is connected to the chip and also serves as the IC’s bi-directional communication interface.

Data are transmitted by modulating the amplitude of the RF signal. Reading of register contents occurs by damping the coil by an internal load. Writing into registers occurs by interrupting the RF field in a specific way. The TK5551 transponder operates at a nominal frequency of 125 kHz. There are different bit rates and encoding schemes.

The on-chip 264-bit EEPROM 8 block, 33 bits each can be read and written block wise from the base station. The blocks can be protected against overwriting by using lock bits. One block is reserved for setting the operation modes of the IC. Another block contains a password to prevent unauthorized writing.
