... 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 ATA5570 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 ...

... ATA5570 – Building Blocks Figure 4-1. 4.1 Analog Front End (AFE) The AFE includes all circuits which are directly connected to the coil. It generates the IC’s power supply and handles the bi-directional data communication with the reader. It consists of the fol- lowing blocks: • Rectifier to generate a DC supply voltage from the AC coil voltage • ...

... The mode register stores the configuration data from the EEPROM block continually refreshed at the start of every block read and (re-)loaded after any POR event or reset com- mand. On delivery, the mode register is preprogrammed with the value 0014 8000h which corresponds to continuous read of block 0, Manchester coded, RF/64. ATA5570 [Preliminary] 4 4863A–RFID–07/05 ...

... Blocks 1 and 2 of page 1 contain traceability data and are transmitted with the modulation parameters defined in the configuration register after the opcode “11” is issued by the reader (Figure 5-6 on page Figure 4-3. ATA5570 [Preliminary] 6 12). These traceability data blocks are programmed and locked by Atmel. Memory Map ...

... CID) are by default reset (= 00) as the Atmel standard value (other values may be assigned on request to high volume customers as CID) and the least 3 bits (ICR) are used by Atmel for the IC and/or foundry version of the ATA5570. The lower 40 bits of the data, encode the traceability information of Atmel and conform to a unique numbering system ...

... EEPROM block 0. If the POR delay bit is reset, no additional delay is observed after the configu- ration period. Tag modulation in regular-read mode will be observed about 3 ms after entering the RF field. If the POR delay bit is set, the ATA5570 remains in a permanent damping state until 8190 internal field clocks have elapsed. ...

... In password mode (PWD bit set), the direct access to a single block needs the valid 32-bit pass- word to be transmitted after the page access opcode, whereas a “0” bit and the 3-bit block address follow afterwards. In case the transmitted password does not match with the contents of block 7, the ATA5570 tag returns to the regular-read mode. Note: 5.5 ...

... The time between two gaps is nominally 24 field clocks for a “0” and 54 field clocks for a “1”. When there is no gap for more than 64 field clocks after a previous gap, the ATA5570 exits the write mode. The tag starts with the command execution if the correct number of bits were received ...

... Write data in normal mode 5.8 Write-data Protocol The ATA5570 expects to receive a dual-bit opcode as the first two bits of a reader command sequence. There are three valid opcodes: • The opcodes “10” and “11” precede all block-write and direct-access operations for page 0 and page 1 • ...

... Answer-on-request (AOR) Mode When the AOR bit is set, the ATA5570 does not start modulation in the regular-read mode after loading configuration block 0. The tag waits for a valid AOR data stream (“wake-up command”) from the reader before modulation is enabled. The wake-up command consists of the opcode (“ ...

... If the command sequence was received successfully, the following error could still prevent programming: • The lock bit of the addressed block is already set In case of a locked block, programming mode will not be entered. The ATA5570 reverts to block- read mode, continuously transmitting the currently addressed block. 4863A–RFID–07/05 This timing and behavior is different from the e555x-family predecessors ...

... OTP Functionality If the OTP bit is set to “1”, all memory blocks are write protected and behave as if all lock bits are set to “1”. If, additionally, the master key is set to “6”, the ATA5570 mode of operation is locked forever (= OTP functionality). If the master key is set to “9”, the test-mode access allows the re-configuration of the tag. ...

... Block 1 Regular-read mode The ATA5570 sequence-start marker is a special damping pattern which may be used to syn- chronize the reader. The sequence start marker consists of two bits (“01” or “10”) which are inserted as header before the first block to be transmitted if the bit 29 in extended mode is set. At the start of a new block sequence, the value of the two bits is inverted ...
