Sensor Input
Memory
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 regu-
lar-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 4-6 on page
Figure 3-3.
S
> 100 k (typical). Otherwise, the output data stream is not inverted (“normal”).
