TK5561A-PP
Description
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. For this reason, the
TK5561A-PP has an additional encryption algorithm block which enables a base sta-
tion to authenticate the transponder. Any attempt to fake the base station with a wrong
transponder will be recognized immediately. For authentication, the base station trans-
mits a challenge to the TK5561A-PP. This challenge is encrypted by both the IC and
the base station. Both should possess the same secret key. Only then can the results
be expected to be equal.
For detailed technical information about functions, configurations etc., please refer to
the e5561 data sheet.
