e5530
128-Bit IDIC
廬
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
廬
. The frequency is
typically 100 to 450 kHz. Receiving RF, the IDIC
廬
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.
