The MicroRWD MIFARE LP (Low Power) module is a complete read and write solution for 13.56 MHz MIFARE Classic® cards (1K, 4K and Ultralight® versions) and supports MIFARE® contactless operations to dual-interface cards such as MIFARE ProX®, Smart MX® (JCOP) and other types. DESfire® and MIFARE Plus® cards are supported for serial number acquisition only. The solution is entirely housed within a 24-pin DIL package and only needs an antenna connected and a 5v DC supply to be a fully featured ISO14443A MIFARE® read/write system. The MicroRWD MIFARE LP version behaves in the same manner as the standard reader except that it has a lower average current consumption. Actual consumption depends upon antenna circuit impedance at 13.56MHz and polling rate selected. As on other RWD modules, all commands and data response are via a simple TTL level RS232 interface. In addition, the RWD MF LP version has auxiliary data outputs on the OP0 / OP1 pins that can be programmed to automatically output UID (serial number) or other block data as asynchronous 9600 baud serial or Wiegand protocol Data High / Data Low signals. All these features can be configured and turned ON/OFF by setting RWD EEPROM parameters.
Low-cost proximity RFID reader module fully supporting Philips / NXP (ISO 14443A) MIFARE Classic® 1K, MIFARE Classic 4K, MIFARE Ultralight® and contactless read/write to MIFARE ProX® and SmartMX® cards and tags. DESFire® and MIFARE Plus® cards are supported for serial number acquisition only.
The RWD module has outstanding RF drive capability and has a read/write range to ISO card size tags of up to 7cm whilst maintaining reliable communication and high resilience to EMC corruption. This has been achieved through extensive software and hardware filtering and optimisation techniques.
