1. Description
The TK5552 is a complete programmable R/W transponder that implements all impor-
tant functions for identification systems. It allows the contactless reading (uplink) and
writing (downlink) of data which are transmitted bi-directionally between a read/write
base station and the transponder. It is a plastic cube device which accommodates the
IDIC transponder IC and the antenna is realized as an LC circuit. No additional exter-
nal power supply is necessary for the transponder because it receives power from the
RF field generated by the base station. Data is transmitted by modulating the ampli-
tude of the RF field (uplink mode). The TK5552 can be used to adjust and modify the
ID code or any other stored data, e.g., rolling code systems. The on-chip 1056-bit
EEPROM (32 blocks, 33 bits per block) can be read (uplink) and written (downlink)
blockwise from the base station. The blocks can be protected against overwriting. One
block is reserved for setting the operation modes of the IC.

... The maximum distance between the base station and the TK5552 depends mainly on the base station, the coil geometries and the modulation options chosen (see “U2270B Antenna Design Hints” application note and the “U2270B” datasheet). When using Atmel’s U2270B demo board, typical distances in the range can be achieved. Maximum distance values which are generally valid can not be given in this datasheet ...
