Precision Industrial Temperature Control

Renesas' 32-bit microcontroller with an analog front end provides temperature measurements with minimal components

Image of Renesas’ Precision Industrial Temperature ControlIndustrial control processes often require accurate temperature monitoring and control. By using the Renesas 32-bit RX23E-A microcontroller (MCU) with a precision analog front end, this system by provides accurate temperature measurements with a minimal number of components.

System Benefits

  • Highly-integrated MCU with 24-bit delta-sigma ADC allows for minimal components
  • RS-485 transceiver with high electrostatic discharge (ESD) protection for robust industrial interfaces
  • Low noise power component selection
  • 32 MHz, 32-bit MCU with built-in analog front end and 24-bit delta-sigma ADCs
  • Wide VIN 500 mA synchronous Buck regulator
  • High-current LDO with low IQ and high PSRR
  • Ultra-low noise, high DC accuracty precision voltage reference with a wide input voltage range
  • 1.9 µVP-P 0.1 Hz to 10 Hz noise with an initial voltage accuracy of 0.02% and 7 ppm/°C
