Products – Micro RWD ICODE SLI (and MIFARE)
  Low-cost proximity "Dual Tag" RFID reader module supporting Philips (ISO 15693) ICODE SLI AND Philips Mifare 1k, 4k and Ultralight transponders/labels.

The module is completely housed within a 24-pin DIP package (pin compatible with
other modules) and only requires a 5v supply and a 1 micro-Henry antenna board to
be a fully featured read/write and tag acceptance system.

The RWD module has outstanding RF drive capability and has a read/write range to ISO
card size labels of up to 10cm whilst maintaining reliable communication and high
resilience to EMC corruption. This has been achieved through extensive software and
hardware filtering and optimisation techniques

 

    

The RWD module has a TTL level RS232 interface that allows a host system to send and receive easy-to-use optimised commands/data (for example: Ascii “R” command to read tag data and Ascii “W” command to write tag data).

The RWD also has internal EEPROM memory for holding system parameters, security key codes, lists of authorised serial numbers and supports direct LED drives to give visual indication of acceptance. Up to 50ma of drive current is also provided as an output that can be used to switch external loads.
