Product details
Overview
R5F523E6MGFM#10 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 ADC with 31.25 kSPS max sampling rate, ±5-V analog input range, 16-bit DAC, dual excitation current sources (50–1000 µA), and on-chip voltage reference (2.5 V, 8 ppm/°C). Operating at up to 32 MHz with 256 KB flash and 32 KB SRAM, it targets load cell, pressure transducer, and weigh scale signal conditioning.
For engineers reviewing the R5F523E6MGFM#10 datasheet, R5F523E6MGFM#10 pinout, R5F523E6MGFM#10 application, or R5F523E6MGFM#10 equivalent, key selection criteria include its 31.25 kSPS delta-sigma ADC performance at ±5 V full-scale, integrated PGA gain settings (×1 to ×128), low-drift voltage reference, and support for IEC60730-compliant self-diagnostic functions in safety-critical sensor systems.
Technical Context
The R5F523E6MGFM#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU and DSP instructions, enabling real-time floating-point computation for sensor linearization and compensation algorithms. Its clock system includes PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator, with independent clock domains for DSAD (PCLKC ≤ 16 MHz) and S12AD (PCLKD ≤ 32 MHz).
Analog subsystem architecture centers on the DSADB unit with fourth- and fifth-order sinc filters, programmable data rate (3.8 SPS to 31.25 kSPS), simultaneous 50/60 Hz rejection, and hardware-assisted disconnect detection for HVAIN pins. The AFEA block provides rail-to-rail PGA, bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), and two matched excitation current sources with ±0.2% matching and 5 ppm/°C drift.

Applications
| Industrial Weigh Scales | Pressure Transmitter Signal Conditioning |
|---|---|
|
Use Scenario: High-accuracy weight measurement in platform scales and hopper load cells using full-bridge strain gauges. IC Role / Device Role / Timing Role: Primary signal conditioner MCU: digitizes mV-level bridge output via DSAD, applies linearization and temperature compensation in real time using FPU, and communicates calibrated weight via SCI or CAN. Use Value: 31.25 kSPS sampling enables fast settling response (<100 ms) for dynamic weighing; ±5-V HVAIN pins eliminate external level-shifting; built-in excitation sources ensure ratiometric accuracy. |
Use Scenario: 4–20 mA loop-powered pressure transmitter with HART modulation, requiring precision analog acquisition and diagnostics. IC Role / Device Role / Timing Role: System-on-chip controller handling sensor excitation, 24-bit sigma-delta conversion, digital compensation, HART physical layer (SCI UART), and loop power management. Use Value: Integrated 2.5 V reference (8 ppm/°C) and matched excitation currents (±0.2%) directly support 0.1% total unadjusted error (TUE); IEC60730 assist functions satisfy SIL-2 functional safety requirements. |
| Temperature-Controlled Test Equipment | Multi-Sensor Industrial Data Logger |
|
Use Scenario: Benchtop calibration equipment measuring thermocouples, RTDs, and thermistors with cold-junction compensation and auto-ranging. IC Role / Device Role / Timing Role: Precision analog acquisition hub: routes multiple sensor types via AMUX, selects PGA gain per channel, performs oversampled conversion, and computes compensated values using floating-point math. Use Value: 24-bit DSAD with selectable sinc filters achieves >100 dB SNR at 3.8 SPS; internal temperature sensor (±5°C) enables CJC; 16-bit DAC provides programmable reference or bias voltage. |
Use Scenario: Battery-powered remote monitoring node acquiring strain, temperature, and humidity from distributed sensors in factory automation. IC Role / Device Role / Timing Role: Low-power data aggregation MCU: samples analog sensors at scheduled intervals using LPT wakeup, stores logs in data flash, and transmits via RSPI to gateway. Use Value: Three low-power modes (sleep/deep sleep/software standby) + LPT allow <1 µA standby current; 8 KB data flash supports 1M write cycles for long-term logging; ELC reduces active time by chaining MTU→DSAD→DTC transfers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6KDFM#10 | Same package and memory, but supports ±10-V analog input range and higher DSAD sampling (125 kSPS) | Required for sensors with >5-V output swing (e.g., high-output load cells, piezoresistive sensors) | Select when full-scale input exceeds ±5 V or higher sampling bandwidth is needed; otherwise R5F523E6MGFM#10 offers better cost/performance for standard industrial sensors. |
| ADUCM360BCPZ-RL7 | Analog Devices ARM Cortex-M3 with 24-bit ΣΔ ADC (3.75–2400 SPS), no integrated PGA or excitation sources | Lacks on-chip excitation current sources and rail-to-rail PGA; requires external components for bridge biasing and gain | Choose when existing analog front-end design exists or when lower sampling rates suffice; R5F523E6MGFM#10 reduces BOM count and layout complexity with integrated AFE. |
Compared with R5F523E6KDFM#10, R5F523E6MGFM#10 trades ±10-V input and 125 kSPS for lower cost and identical integration of PGA, excitation sources, and safety features - making it optimal for ±5-V bridge sensors. Against ADUCM360, it delivers superior system-level integration with no external AFE components required.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MGFM#10?
The R5F523E6MGFM#10 supports a maximum delta-sigma ADC sampling rate of 31.25 kSPS at ±5-V full-scale input range. This rate is achieved with modulator clock fMOD = 4 MHz and appropriate sinc filter configuration. Lower rates (down to 3.8 SPS) are selectable to improve noise performance and enable simultaneous 50/60 Hz rejection.
Does R5F523E6MGFM#10 include an integrated programmable gain amplifier (PGA)?
Yes, R5F523E6MGFM#10 includes a rail-to-rail input programmable gain instrumentation amplifier with gain settings of ×1, ×2, ×4, ×8, ×16, ×32, ×64, and ×128. It achieves 11 nVRMS input-referred noise at gain = 128 and 3.8 SPS, with offset drift of 4 nV/°C for gains 64–128 - critical for stable low-level sensor signal amplification.
What analog input voltage range does R5F523E6MGFM#10 support?
R5F523E6MGFM#10 supports a ±5-V analog input range on its HVAIN pins (HVAIN0–HVAIN3), as indicated by the "M" suffix in its part number per Renesas' naming convention. It does not support ±10-V input - that capability is reserved for "K" and "L" variants such as R5F523E6KDFM#10.
Is R5F523E6MGFM#10 qualified for industrial temperature operation?
Yes, R5F523E6MGFM#10 is the D-version device rated for –40°C to +85°C ambient operating temperature. This qualification aligns with industrial-grade requirements and is verified across all integrated peripherals including the 24-bit DSAD, PGA, voltage reference, and excitation current sources.
Does R5F523E6MGFM#10 include hardware support for IEC60730 compliance?
Yes, R5F523E6MGFM#10 integrates multiple hardware-assisted IEC60730 functions: self-diagnostic routines for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the data operation circuit (DOC), and analog input disconnect detection - reducing software validation burden for Class B safety certification.
