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.

The code line is exactly as long as the selected code length (e.g. 64 bits 16
hex numbers).
The line must end with a carriage return.
The first 8 bits are fixed, this is the unique customer header which is defined
by Atmel.
Each hexadecimal code entry must be preceded by a decimal serial number.
Serial number and code must be separated by a space.
The serial number has to be unique and is up-counting to avoid double
programming.
The series numbers of two consecutive files (file name!) has to count also
for proper linking.
