Description The Atmel® ATA5575M2 is a contactless read/write identification IC (IDIC®) for applications in the 100-k Hz to 150-k Hz frequency band. A single coil connected to the chip serves as the IC's power supply and bi-directional munication 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 mands (downlink), which are encoded as 100% amplitude-modulated (OOK) pulse-interval-encoded bit streams. The Atmel ATA5575M2 is an EEPROM-based circuit. It is optimized for maximum read range. Programming is also possible but the write range is limited. The typical animal ID application conforming to ISO11784/85 is read-only and operates at 134.2k Hz. The Atmel ATA5575M2 thus has to be locked after programming the animal-specific code. 2.
