1. Description
The Atmel® ATA5575M2 is a contactless read/write identification IC (IDIC®) for applications in the 100-kHz to 150-kHz frequency band. A single coil connected to the chip serves as the IC's power supply and bi-directional communication interface. This antenna coil together with the chip form a transponder or tag.
The on-chip 128-bit User EEPROM (16 bytes with 8 bits each) can be read and written byte-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.
The Atmel ATA5575M2 is an EEPROM-based circu...
