TMS37157IRSARG4 Allgemeine Beschreibung

In addition to managing Transponder communication and push button interaction, the TMS37157 also excels in power management, entering a special low power mode with a current consumption of only 60 nA during sleep state. The EEPROM memory is easily accessible over the LF interface without battery support or through SPI with a connected microcontroller, and the device offers a special battery charge mode

APPLICATIONS
- Wireless Batteryless Sensor Interface using
  Energy Harvesting
  - Microcontroller and Sensor can be Powered Through the
    LF Link
  - Data is Directly Transmitted Over the LF Link From the
    Base Station via the TMS37157 to the Micrcontroller and Vice
    Versa.
- Batteryless Configuration Memory
  - Memory can be Written Without Battery Support
  - Microcontroller can Read the Content of the Memory When
    It Gets Connected to a Battery and Use It for Configuration
  - Microcontroller can Write the Memory, Which can be Read Out
    Later Through the LF Link
- Ultra Low Power Data Logger Memory (Smart Metering)
  - Memory Can Be Written By a Microcontroller
  - Memory Can Be Read Through LF Interface Without
    Battery Support
- Multi Purpose LF Interface to a Microcontroller
  - Short Range RF Interface to a Microcontroller Where
    Other Frequencies are Not an Option
  - Ultra Low Power Mode can Result in an
    Overall Power Consumption of 60 nA
- Remote Control Application
  - Combination With an UHF Transmitter or IR Transmitter and a µC
  - Power Management of the TMS37157 can Power Down
    the Microcontroller
  - The Push Button Detection Circuit can Power Up a
    Microcontroller
- Stand Alone LF-Transponder with Memory
  - RFID Transponder with Unique ID and 121
    Bytes Free Programmable EEPROM User Memory
  - Only Few Additional Components Needed
  - No Battery Required
