The TK5552 is a complete programmable R/W transponder which implements all important functions for identification systems.
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.
| Nominal Frequency | 125 kHz |
|---|---|
| EEPROM Capacity | 1056-bit |
| Operating Temperature Range | -25 to +75 °C |
| Storage Temperature Range | -40 to +125 °C |
| Data Retention | 10 Years |
| Programming Cycles | 100,000 |
It receives power from the RF field generated by a read/write basestation via inductive coupling.
The device typically takes less than 50 ms to write and verify a block.
