Product Summary

The EM4095HMS is a CMOS integrated transceiver circuit intended for use in an RFID basestation to perform the following functions: antenna driving with carrier frequency; AM modulation of the field for writable transponder; AM demodulation of the antenna signal modulation induced by the transponder communicate with a microprocessor via simple interface. The applications of the EM4095HMS include Car immobiliser, Hand held reader, Low cost reader.
