The MicroRWD MICODE module is a complete “contactless” read / write solution for 13.56 MHz MIFARE Classic® 1K, MIFARE Classic® 4K, MIFARE Ultralight®, ProX®, Smart MX®, JCOP), ICODE® SLI and ISO14443B (Calypso Rev2) cards and tags. DESfire®, MIFARE Plus® and ISO14443B Calypso 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 and ISO15693 Reader system. The MicroRWD MF-IC (low power) version behaves in the same manner as other IBT RWD (Read/Write Devices) except that it has an average current consumption of down to 150μA (micro Amps) even when fully active (with 1 second polling rate selected). Internal EEPROM memory is used to store Authentication keys, lists of authorised serial numbers and configuration parameters. The MicroRWD MICODE is pin compatible with previous IBT RWD modules and has LED drives to give visual indication of acceptance and a simple TTL level RS232 interface for all commands and data response. In addition, the RWD MF-IC version has a programmable “BEEP” output for external control and auxiliary data outputs on the OP0 / OP1 pins. These 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 supporting PHILIPS/NXP (ISO 14443A) MIFARE Classic® 1K, MIFARE Classic® 4K, MIFARE Ultralight®, MIFARE ProX®, SmartMX®, (ISO15693) ICODE® SLI and ISO14443B Calypso cards and tags. DESFire®, MIFARE Plus® and ISO14443B Calypso cards are supported for serial number acquisition only.
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 tags 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.
