MCUs for precision sensing and measurement

29 July 2020 DSP, Micros & Memory

A new series of single-chip devices from Renesas, the RX23E-A microcontrollers (MCUs), combine an analog front end (AFE) and an MCU core for use in equipment that delivers high-precision measurements of analog signals, such as temperature, pressure, weight, or flow.

Designed for manufacturing and test and measurement equipment, such as sensing or force measuring devices or temperature controllers, the RX23E-A group of MCUs offers better than 0,1% precision without calibration. Integrating dual 24-bit delta-sigma A/D converters with up to 23-bit effective resolution, and programmable data rates from 7,6 samples/s up to 15 625 ksamples/s, other specific leading-edge features of the AFE include offset drift of 10 nV/°C, gain drift of 1 ppm/°C, and RMS noise of 30 nV.

The digital part of the RX23E-A devices is based on an advanced RXv2 core, which features operating speeds of 32 MHz and excels at DSP and FPU (floating point unit) operations. The microcontroller also enables adaptive control techniques using temperature data and inverse matrix calculations based on six-axis distortion data, which can make it ideal for robot-arm force sensors in industrial manufacturing applications.
