RFid Reader Board

Product Code: MIKROE-262

EM4095 CMOS integrated transceiverThe EM4095 (also known as P4095) chip is a 125 KHz-134 KHz, Read/Write analog front end for RFID basestation. This circuit, which is meant for use in an RFID basestation, carries out antenna driving with carrier frequency while communicating with a microprocessor via simple interface. It does AM modulation of the field for writable transponder and AM demodulation of the antenna signal modulation induced by the transponder.Operating VoltageThe RFid Reader Board operates on 5V power supply only. For connecting it to 3.3V systems, the user must use voltage translators on communication lines.ApplicationsThe RFid Reader Board can be used to read code from 125 kHz RFid tags or identification cards. This makes it ideal for use in car immobilizers, hand held reader and designing low cost readers.
