A single coil, connected to the chip, serves as the IC’s power supply and bi-directional communication interface. The antenna and chip together form a transponder or tag. The on-chip 330-bit EEPROM 10 blocks, 33 bits each can be read and written block-wise from a reader. Block 0 is reserved for setting the operation modes of the ATA5570C tag. Block 7 may contain a password to prevent unauthorized writing. Data is transmitted from the IDIC using load modulation. This is achieved by damping the RF field with a resistive load between the two terminals COIL1 and COIL2. The IC receives and decodes 100% amplitude-modulated OOK pulse-interval-encoded bit streams from the base station or reader.

It generates the IC’s power supply and handles the bi-directional data communication with the reader. It consists of the following blocks: • Rectifier to generate a DC supply voltage from the AC coil voltage • Clock extractor • Switchable load between COIL1 and COIL2 for data transmission from tag to the reader • Field gap detector for data transmission from the base station to the tag • ESD protection circuitry 2 Atmel ATA5570C Atmel ATA5570C Data-rate Generator The data rate is binary programmable to operate at any data rate between RF/2 and RF/128 or equal to any of the fixed e5550/e5551 and Atmel T5554 bit rates RF/8, RF/16, RF/32, RF/40, RF/50, RF/64, RF/100 and RF/128 . Write Decoder This function decodes the write gaps and verifies the validity of the data stream according to the Atmel e555x write method pulse interval encoding . HV Generator This on-chip charge-pump circuit generates the high voltage required for programming of the EEPROM.
