E5530 Datasheet | TEMIC Semiconductors

128-Bit IDIC® for Radio Frequency Identification 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 to 450 k Hz. Receiving RF, the IDIC® responds with a data stream by damping the ining 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 laserprogrammable fuses. The logic block diagram for the e5530 is shown in figure 2. The data are output bitserially as a code of length 128, 96, 64 or 32 bits. The chips are factory-programmed with a unique code.
