125KHZ-134KHZ, READ/WRITE ANALOG FRONT END FOR RFID BASESTATION
The EM4095 (previously named P4095) chip 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
