This 100g weight scale reference design targets industrial and medical applications. The RX23E-A 32-bit MCU’s integrated analog front end (AFE) measures temperature, pressure, flow, and weight with less than 0.1% precision without calibration, making it ideal for high-precision temperature sensing.

System Benefits​:

  • RX23E-A allows for a low component count with an integrated analog front end.
  • Temperature sensor is integrated into the reference design.




  • Industrial or medical weight scales
