Sensor Input
Memory
ATA5570 [Preliminary]
Modulated output data stream depends on the state of the sensor input. The data stream is
inverted when external resistance, connected between Sensor input and VSS, is more than
R
The memory is a 330-bit EEPROM, which is arranged in 10 blocks of 33 bits each. All 33 bits of
a block, including the lock bit, are programmed simultaneously.
Block 0 of page 0 contains the mode/configuration data, which is not transmitted during regular-
read operations. Block 7 of page 0 may be used as a write-protection password.
Bit 0 of every block is the lock bit for that block. Once locked, the block (including the lock bit
itself) is not re-programmable through the RF field.
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.
S
> 100 k (typical). Otherwise, the output data stream is not inverted (“normal”).
