The TK5530 is a complete transponder, which implements all important functions for immobilizer and identification systems. It consists of a plastic cube which accommodates the read-only IDentification Integral Circuit IDICÒ e5530 and the antenna is realized by a LC-circuit.

The identifying data are stored in a 128 bit PROM on the e5530, realized as an array of laser-programmable fuses. The logic block diagram for the e5530 is shown in Figure The data are sent bit-serially as a code.

General

Read-Only IDICÒ
with ROM e5530

The transponder consists of a plastic cube which accommodates following components
• Read-only IDICÒ with ROM e5530
• Antenna realized as tuned LC-circuit

The e5530 is part of a closed coupled identification system see ’System Block Diagram’ . It receives power from a RF transmitter reader which is coupled inductively to the IDIC. The TK5530 transponder operates at a nominal frequency of 125 kHz. Receiving RF, the IDIC responds with a data stream by damping the incoming RF via an internal load. This damping in turn can be detected by the reader. The identifying data are stored in a 128-bit PROM on the e5530, which is factory programmed with a unique code see specification of the e5530 .

The e5530 has several possible options regarding modulation, bitrate, memory size etc.

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 readout distance.
