详细说明： The MicroRWD MF 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 re ad/write system. The MicroRWD MF LP version behaves in the same manner as the standard reader except that it has an active, average current consumption of less than 150µµµ µA (micro Amps) with 1 second polling rate. 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. The diagram below shows the pin out configuration for the MicroRWD MF LP module ...展开收缩
