EM4095

125KHz-134 KHz, Read write analog front end for RFID basestation.

PRODUCT 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.

FEAUTRES:

• Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency
  
• No external quartz required
  
• 100 to 150kHz carrier frequency range
  
• Direct antenna driving using bridge drivers
  
• Data transmission by OOK (100% Amplitude Modulation) using bridge driver
  
• Externally adjustable modulation index 
  
• Multiple transponder protocol compatibility (Ex: EM4100, EM4102, EM4150, EM4170, EM4069.)
  
• Sleep mode consumption 1µA
  
• USB compatible power supply range
  
• -40 to +85°C temperature range
  
• Plastic package SO16 or PSOP2 16

APPLICATIONS:

• Car immobiliser
  
• Hand held reader
  
• Low cost reader
