The TK5552 is a complete programmable R/W transponder that implements all importantfunctions for identification systems. It allows the contactless reading (uplink) andwriting (downlink) of data which are transmitted bi-directionally between a read/writebase station and the transponder. It is a plastic cube device which accomodates theIDIC transponder IC and the antenna is realized as an LC circuit. No additional externalpower supply is necessary for the transponder because it receives power from theRF field generated by the base station. Data is transmitted by modulating the amplitudeof the RF field (uplink mode). The TK5552 can be used to adjust and modify theID code or any other stored data, e.g., rolling code systems. The on-chip 1056-bitEEPROM (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.
