Figure 2: RFM Block Schematic
The RA-RFM contains all the analogue functions of a TI-RFID reading unit needed
to initialize a TI-RFID transponder, delivering data and clock signals for
identification data processing.
The RA-RFM also sends the necessary programming and addressing signals to
Read/Write and Multipage transponders.
The data input and output lines, which are connected to a data processing unit, are
low-power Schottky TTL and HCMOS logic compatible.
The functions of the RA-RFM are described in the following section.
