Overview

Description

The RX23E-B Group of microcontrollers has a built-in analog front end (AFE) that is ideal for industrial sensor equipment. Compared to the RX23E-A, the high-speed performance and noise performance of the RX23E-B 24-bit delta-sigma A/D converter have been improved. The maximum data rate is 125kSPS, which is fast for a delta-sigma A/D converter and is eight times faster than the RX23E-A. RMS noise has been reduced to about 1/3 of that of the RX23E-A, making it possible to measure strain, temperature, pressure, flow, current, voltage, etc. at high speed and with accuracy. The RX23E-B also has an integrated 16-bit D/A converter and +/-10V high-voltage analog signal input circuit, reducing the overall bill of materials (BOM) and footprint. The CPU is equipped with an RXv2 core that offers excellent digital signal processing (DSP)/floating-point unit (FPU) operation, which enables high-precision measurement, control, and communication on a single chip.

Features

  • Analog front end (AFE)
    • 24-bit delta-sigma A/D converter with integrated programmable gain amplifier: Up to 24-bit effective resolution, data rate 3.8SPS to 125kSPS, 4nV/°C offset drift, 1ppm/°C gain drift
    • 5V analog inputs: Eight differential inputs, 16 single-ended inputs
    • ±10V analog inputs: Two differential inputs, four single-ended inputs
    • 16-bit D/A converter: DNL = ±1LSB, INL = ±5LSB
    • Reference voltage source: Low temperature drift of 10ppm/°C with excellent temperature stability
    • Excitation current source: Matched programmable current source, ideal for measuring 3-wire resistance temperature detectors
  • MCU component
    • CPU: 32-bit RXv2 core, operating frequency 32MHz, digital signal processing can be implemented with DSP instructions and FPU
    • Communication interface: SPI x 1 channel, UART x 7 channels, I2C x 1 channel, CAN x 1 channel
