The Texas Instruments TMS37157IRSARG4 is a Passive Low Frequency Interface Device (PaLFI) with EEPROM and a 134.2 kHz transponder interface. This RFID Transponder IC is designed for applications requiring wireless batteryless sensor interfaces, data logging, and multi-purpose LF interfaces to microcontrollers.
Key electrical specifications include an operating frequency of 134.2 kHz, a wide supply voltage range of 2V to 3.6V, and ultra-low power consumption. In active mode, it consumes a maximum of 150 µA, while in power-down mode, consumption drops to 60 nA. It supports HDX-FSK transmission principles and offers an LF uplink data rate of up to 8 kbit/s.
The device features 121 free bytes of EEPROM user memory, a 32-bit unique serial number, and an 8-bit selective address. The EEPROM offers high flexibility with pages that are irreversible, lockable, and protectable. It also includes battery check and battery charge functions.
Packaged in a 16-VQFN exposed pad (4mm x 4mm) with a 0.6mm pitch, the TMS37157IRSARG4 is designed for surface mounting. Its SPI interface allows for accessing the EEPROM and exchanging data with a microcontroller through the LF interface. This component is suitable for batteryless configurations and can be powered through the LF link, making it ideal for energy harvesting applications.
