Atmel TK5552 Read/Write Transponder Datasheet
The document describes the Atmel TK5552, a complete programmable read/write transponder designed for identification systems. It operates as a plastic-cube device containing an IDIC Transponder IC, a built-in coil, and a capacitor to form an LC circuit antenna.
The transponder utilizes inductive coupled power supply at 125 kHz, receiving energy from the RF field generated by a base station without requiring external power. Data transmission is bidirectional: uplink (reading) modulates the amplitude of the RF field, while downlink (writing) interrupts the RF field with specific gaps to encode data into an on-chip 1056-bit EEPROM organized in 32 blocks.
