ATA5577
1. Description
The ATA5577 is a contactless read/write identification IC (IDIC®) for applications in
the 125-kHz or 134-kHz frequency band. A single coil connected to the chip serves as
the ICâs 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.
