LF transponder134.2 kHzEEPROMSPIVQFN-16low power

TMS37157IRSARG4 is a Texas Instruments passive 134.2 kHz LF transponder interface IC with EEPROM, SPI connectivity, antenna trimming, and power management.

Best for

  • Batteryless LF sensor interfaces
  • 134.2 kHz RFID transponders with EEPROM
  • Low-power data logging and configuration storage

Avoid if

  • The design requires a different RF frequency
  • The application cannot support the specified external LF resonance network

Check before use

  • Supply and charge-capacitor limits
  • Antenna inductance, resonance, and field strength
  • SPI BUSY-handshake timing
  • VQFN footprint and exposed thermal pad
