Application RF transmitter and interrogator 128-bit Read-only IDIC for RF Identification e5530 IDIC RF ID e5530 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 IDIC  responds 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. Figure 2.

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. Rectifier 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 th.
