Hot sale original electronics EM Microelectronic EM4095001 Read/Write analog front end for 125kHz RFID Basestation

Product Details

125KHZ-134KHZ, READ/WRITE ANALOG FRONT END FOR RFID BASESTATION

  Description        

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.

   Features     

• Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency

• No external quartz required

• 100 to 150 kHz carrier frequency range

• Direct antenna driving using bridge drivers

• Data transmission by OOK (100% Amplitude Modulation) using bridge driver

• Data transmission by Amplitude Modulation with externally adjustable modulation

     index using single ended driver

• Multiple transponder protocol compatibility

     (Ex: EM400X, EM4050, EM4150, EM4070, EM4170, EM4069….)

• Sleep mode 1µA

• USB compatible power supply range

• 40 to +85°C temperature range

• Small outline plastic package SO16

Applications

• Car immobiliser

• Hand held reader

• Low cost reader
