Description
The e5530 is part of a closed coupled identification system. It receives power from an
RF transmitter which is coupled inductively to the IDIC. The frequency is typically
100 kHz to 450 kHz. Receiving RF, the IDICresponds with a data stream by
damping the incoming RF via an internal load. This damping-in-turn can be detected
by the interrogator. 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 2. The data are output bit-serially as a code of length
128, 96, 64 or 32 bits. The chips are factory-programmed with a unique code.

Functional Description
Read Operation
Rectifier
Damping Load
After power up, once the e5530 has detected the incoming RF field, the IC continuously
transmits the identification code as long as the RF signal is applied. The transition from
the last bit to bit 1 of the next sequence occurs without interruption. Data is transmitted
by damping the incoming RF signal by an internal load. These load changes are
detected by the reader station.
Different kinds of modulation and bitrates are optionally available.
For internal power supply, an on-chip bridge rectifier is used which consists of two
diodes and two n-channel transistors. A Zener diode, which protects the circuit against
overvoltage on the coil inputs, and a smoothing capacitor for the internal supply are also
provided.
Incoming RF will be damped by the power consumption of the IC itself and by an
internal load, which is controlled by the modulator. The loads are p-channel transistors
connected between VDD and the coil inputs.
The IDIC includes mask options for the load circuit: single-side, double-side and
alternate-side modulation.
There are four modulation methods available which can be selected by fuses. The
corresponding timing diagram is shown in Figure 5.
