Overview

The R5F523E6ADFL#30 is a 32-bit microcontroller from the Renesas RX23E-A group, specifically designed for high-precision analog sensing applications. It features an integrated 24-bit Delta-Sigma ADC and a 32MHz RXv2 core with an FPU, making it a single-chip solution for signal conditioning and processing in industrial environments.

Why Choose This Part

This MCU eliminates the need for external high-resolution ADCs and instrumentation amplifiers, reducing PCB footprint and BOM cost. The RXv2 core provides 3.22 CoreMark/MHz efficiency, while the integrated FPU and DSP instructions simplify complex filter implementation for noisy industrial signals.

Applications

Precision Temperature Controllers
Using the 24-bit ADC for high-resolution thermocouple or RTD measurements with built-in excitation currents.
Strain Gauge Transducers
Direct interfacing with bridge sensors for weight scales and force measurements without external analog front-ends.
Industrial Pressure Sensors
On-chip signal conditioning and DSP instructions allow for real-time compensation of pressure sensor nonlinearities.
Battery-Powered Data Loggers
Utilizing the 0.4uA software standby mode for long-term monitoring in remote sensing nodes.

Getting Started

Development is supported by the Renesas e2 studio IDE and the CC-RX compiler. For evaluation of the precision analog front-end, the RTK7RX23E0C00000BR Evaluation Board provides a verified reference design for sensor interfacing.
