ICODE 3 (TagTamper)

8 Functional description

8.1 Block description

The ICODE 3 includes three major blocks: the analog RF interface, the digital controller, and the EEPROM.

Analog RF interface

The interrogator generates an electromagnetic field. The analog RF interface generates the stable power supply

and the system clock from the electromagnetic field via the antenna. The ICODE 3 requires no internal power

supply.

The analog RF interface also includes:

• The demodulator: Demodulates the data transmitted from the interrogator to the ICODE label. The data is

then processes in the digital control block.

• The modulator: Modulates the electromagnetic field for data transmission from the ICODE label to the

interrogator.

Digital control block

The digital control block includes the state machines. The block is used to process the data and to handle the

communication with the EEPROM.

EEPROM

Data are stored in a non-volatile memory (EEPROM).
