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.
