Power-On Reset (POR)
This circuit delays the IDIC functionality until an acceptable voltage threshold has been
reached.
Clock Extraction
The clock extraction circuit uses the external RF signal as its internal clock source.
Controller
The control-logic module executes the following functions:
Load-mode register with configuration data from EEPROM block 0 after power-on
and also during reading
Control memory access (read, write)
Handle write data transmission and write error modes
The first two bits of the reader to tag data stream are the opcode, e.g., write, direct
access or reset
In password mode, the 32 bits received after the opcode are compared with the
password stored in memory block 7
Mode Register
The mode register stores the configuration data from the EEPROM block 0. It is
continually refreshed at the start of every block read and (re-)loaded after any POR
event or reset command. On delivery the mode register is preprogrammed with the
value ‘0014 8000’h which corresponds to continuous read of block 0, Manchester
coded, RF/64.
