Overview

Description

The RX23E-A group microcontrollers are equipped with an analog front-end that can measure temperature, pressure, flow, and weight with less than 0.1% precision without calibration, making it ideal for high-precision sensing, test and measurement equipment. The CPU is equipped with an RXv2 core that excels in DSP/FPU operations, enabling high-accuracy measurement, control and communication with a single chip.

Features

Analog Front End Features

  • 24-bit delta-sigma A/D converters: Up to 23-bit effective resolution, programmable data rate 7.6sps to 15.6ksps
    • Dual 24-bit delta-sigma A/D converters (R5F523ExAxxx)
    • Single 24-bit delta sigma A/D converter (R5F523ExSxxx)
  • PGA: Rail-to-rail analog input, Gain 1 to 128, offset drift 10 nV/°C, gain drift 1 ppm/°C
  • Voltage reference: low drift 10ppm/°C with good temperature stability
  • Excitation current source: Matched programmable current source

MCU Features

  • CPU: 32-bit RXv2 (32MHz), DSP/FPU for digital signal processing
  • Interface: SPI x 1ch, UART x 4ch, I2C x 1 ch, CAN x 1ch
