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 7.6 sps to 15.6 ksps
    • 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 4ppm/°C with good temperature stability
  • Excitation Current Source: Matched programmable current source
MCU Features
  • CPU: 32-bit RXv2 (32 MHz), DSP/FPU for digital signal processing
  • Interface: SPI x 1 ch, UART x 4 ch, I2C x 1 ch, CAN x 1 ch
