The TK5561A-PP is a complete transponder integrating all important functions for immobilizer and identification systems. It consists of a plastic cube which accommo- dates the crypto IDIC e5561A and the antenna realized as tuned LC-circuit. The TK5561A-PP is a R/W crypto transponder for applications which demand higher secu- rity levels than those which standard R/W transponders can fulfil.
The document describes the TK5561A-PP, a complete transponder integrating functions for immobilizer and identification systems. It consists of a plastic cube accommodating the e5561A crypto IDIC and an antenna realized as a tuned LC-circuit.
The device operates at a typical frequency of 125 kHz and features a high-security encryption algorithm block to authenticate with a base station. It includes a 320-bit EEPROM for storing user-programmable IDs, crypto keys, and configurations.
