READ/WRITE ANALOG FRONT END IC WITH SERIAL µC INTERFACE FOR USAGE IN 125 / 134.2 KHZ RFID BASESTATION APPLICATIONS
Description The EM4097 (previously named P4097) chip is a CMOS integrated transceiver circuit intended for use in an RFID basestation to perform the following functions:
- Antenna driving with carrier frequency to transfer energy to the transponder
- Data transfer to writable transponder by amplitude modulation (ASK) of the field (100% modulation ratio, called OOK, “on”-“off” keying)
- Data transfer from transponder by amplitude- or phase demodulation (ASK or PSK)
- µC Interface to municate with a microprocessor
