Description

the 125-kHz or 134-kHz frequency band. A single coil connected to the chip serves as

the IC’s power supply and bi-directional communication interface. The antenna and

chip together form a transponder or tag.

The on-chip 363-bit EEPROM (11 blocks with 33 bits each) can be read and written

block-wise from a base station (reader).

Data is transmitted from the IDIC (uplink) using load modulation. This is achieved by

damping the RF field with a resistive load between the two terminals Coil 1 and Coil 2.

The IC receives and decodes serial base station commands (downlink), which are

encoded as 100% amplitude modulated (OOK) pulse-interval-encoded bit streams.

A complete datasheet with further technical data is available on request. Please con-

tact your local sales office.
