Product details
Overview
R5F523E6NGBS#00 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing applications. It integrates a 24-bit delta-sigma A/D converter with 31.25 kSPS max sampling rate, ±5-V input range, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), on-chip excitation current sources (50–1000 µA), and a low-drift 2.5-V voltage reference (8 ppm/°C). Operating at up to 32 MHz with 256 KB flash, 32 KB SRAM, and CAN 2.0B interface, it targets load cell, pressure transducer, and strain gauge signal conditioning.
For engineers reviewing the R5F523E6NGBS#00 datasheet, R5F523E6NGBS#00 pinout, R5F523E6NGBS#00 application, or R5F523E6NGBS#00 equivalent, key selection criteria include its G-grade (–40°C to +105°C) operation, TFBGA-100 package, integrated analog front-end with HVAIN support, ELC-driven low-power synchronized peripheral triggering, and IEC60730 safety assist functions for Class B compliance.
Technical Context
The R5F523E6NGBS#00 implements a Harvard-architecture RXv2 CPU core with IEEE 754-compliant FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) for deterministic real-time control. Its analog subsystem centers on the DSADB module-synchronized to PCLKC (≤16 MHz)-with fourth- and fifth-order sinc digital filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and offset/gain error calibration.
Digital integration includes an event link controller (ELC) enabling interrupt-free peripheral chaining (e.g., MTU-triggered DSAD conversion), four-channel DMAC for background data movement, and RSCAN CAN module supporting 1 Mbps with 16 message boxes. Power management features three low-power modes, LPT operation during software standby, and voltage detection circuits with 14-level LVDAb configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6LGBS#00 | Same package and core, but supports ±10-V HVAIN input and 125 kSPS DSAD sampling | Required for higher-voltage bridge sensors (e.g., 10-V excitation) or faster transient capture | Select when full-scale input exceeds ±5 V or >31.25 kSPS sampling is needed; otherwise R5F523E6NGBS#00 offers optimal cost/performance for ±5-V systems |
| ADUCM360BCPZ | ARM Cortex-M3 core, 24-bit ΣΔ ADC (3.75–39.5 kSPS), integrated 4–20 mA DAC, no CAN | Targeted at loop-powered 4–20 mA transmitters; lacks CAN, LCD, and ELC event chaining | Prefer R5F523E6NGBS#00 for CAN-connected distributed sensor networks; ADUCM360 suits standalone 4–20 mA field devices |
Compared with R5F523E6LGBS#00, R5F523E6NGBS#00 trades ±10-V input and higher DSAD speed for lower cost and identical thermal robustness, while versus ADUCM360 it adds CAN, ELC, and larger memory-enabling more complex sensor fusion and networked diagnostics.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6NGBS#00?
The R5F523E6NGBS#00 supports a maximum delta-sigma ADC sampling rate of 31.25 kSPS. This rate is achieved with the DSADB module operating at its highest modulator clock setting (4 MHz) and appropriate digital filter configuration. The device also supports lower rates-including 10 SPS and 54 SPS-with simultaneous 50 Hz and 60 Hz noise rejection enabled.
Does R5F523E6NGBS#00 support CAN FD or only classical CAN 2.0B?
R5F523E6NGBS#00 implements the RSCAN module compliant with ISO 11898-1 for classical CAN 2.0B only, supporting data rates up to 1 Mbps with standard and extended frames. It does not support CAN FD features such as flexible data-rate or enhanced payload length; the module is strictly backward-compatible with legacy CAN networks.
What is the operating temperature range certified for R5F523E6NGBS#00?
R5F523E6NGBS#00 is rated for industrial G-grade operation from –40°C to +105°C ambient temperature. This rating is validated across all specified electrical parameters including DSAD performance, flash endurance, and oscillator stability, making it suitable for harsh environments like factory floors and outdoor instrumentation enclosures.
How many excitation current sources does R5F523E6NGBS#00 integrate, and what are their precision specs?
R5F523E6NGBS#00 integrates two independent excitation current sources (IEXC0 and IEXC1) with programmable output from 50 µA to 1000 µA in six discrete steps. Their matching accuracy is ±0.2% over temperature, and drift matching is 5 ppm/°C-critical for ratiometric measurements in bridge-based sensors where current source imbalance directly impacts gain error.
Is the 2.5-V voltage reference in R5F523E6NGBS#00 internally buffered and temperature-stable?
Yes, the R5F523E6NGBS#00 includes an internally buffered 2.5-V voltage reference (VREF) with a temperature coefficient of 8 ppm/°C over –40°C to +85°C. It delivers ±10 mA output current and is explicitly designed for use as the DSAD reference, enabling stable ratiometric measurements without external buffering or trimming components.
