Product details
Overview
R5F523E6AGFL#10 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor signal conditioning, featuring dual 24-bit delta-sigma ADCs (23-bit ENOB at 7.6 SPS), rail-to-rail programmable gain instrumentation amplifiers (gain = 1–128), 2.5 V low-drift voltage reference (10 ppm/°C), and integrated excitation current sources (50–1000 µA). It operates at 32 MHz with 256 KB flash, 32 KB SRAM, and supports IEC60730-compliant diagnostics.
For engineers reviewing the R5F523E6AGFL#10 datasheet, R5F523E6AGFL#10 pinout, R5F523E6AGFL#10 application, or R5F523E6AGFL#10 equivalent, this device is selected for high-accuracy weigh scales, temperature transmitters, and resistance-based sensor interfaces requiring simultaneous multi-channel delta-sigma conversion, on-chip PGA calibration, and extended temperature operation up to +105°C.
Technical Context
The R5F523E6AGFL#10 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, programmable data rates (1.9–15625 SPS), and simultaneous 50/60 Hz rejection at 10/54 SPS. Each DSAD unit supports up to six differential inputs and includes offset/gain error calibration, disconnect detection assist, and external reference voltage input.
Its analog front end includes a 2.5 V ±10 ppm/°C voltage reference, bias voltage generator ((AVCC0 + AVSS0)/2), four excitation current sources (±0.2% matching, 5 ppm/°C drift), and a 10 Ω low-side switch. The MCU couples these with a 32-bit RXv2 CPU, FPU, MPU, and ELC for event-driven peripheral coordination without CPU wake-up.

Applications
| Industrial Weigh Scales | Temperature Transmitters |
|---|---|
Use Scenario: High-resolution weight measurement using 4-wire load cells in factory-floor environments with wide ambient temperature swings. IC Role / Device Role / Timing Role: Primary signal conditioner: digitizes mV-level bridge output via DSAD with PGA gain = 128, applies offset/gain calibration, and transmits compensated data over CAN. Use Value: Achieves ≤0.001% full-scale linearity and <10 nV/°C offset drift over –40°C to +105°C, eliminating external zero-span trimmers and reference buffers. |
Use Scenario: DIN-rail-mounted RTD transmitter converting Pt100 signals to 4–20 mA or digital output for PLC integration. IC Role / Device Role / Timing Role: Sensor interface MCU: drives IEXC0/IEXC1 for 3-wire RTD, measures with DSAD0 (differential), compensates using internal TEMPS, and executes linearization in FPU. Use Value: Delivers ±0.1°C accuracy over full range using on-chip excitation matching (±0.2%) and drift compensation (5 ppm/°C), reducing BOM by 4 passive components. |
| Pressure Transducers | Multi-Sensor IoT Gateways |
Use Scenario: MEMS pressure sensor module with integrated temperature compensation and HART/analog output. IC Role / Device Role / Timing Role: Analog front-end controller: conditions bridge output via DSAD1, reads die temperature via TEMPS, and generates calibrated 4–20 mA using DAC-less PWM + filter. Use Value: Simultaneous 50/60 Hz rejection at 10 SPS enables stable readings in electrically noisy plant environments without external notch filters. |
Use Scenario: Edge node aggregating data from multiple analog sensors (load cell, thermocouple, humidity) before wireless transmission. IC Role / Device Role / Timing Role: Multi-sensor hub MCU: sequences DSAD0/DSAD1 conversions via ELC, stores calibrated values in SRAM, and forwards via RSPI to LoRa/Wi-Fi co-processor. Use Value: Background Operation (BGO) on data flash allows firmware updates while maintaining continuous sensor logging-no data loss during field upgrades. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision sensor interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS131M04IPBSR | 4-channel 24-bit delta-sigma ADC only (no MCU, no PGA, no excitation sources) | Requires external microcontroller, reference, and excitation circuitry; lacks integrated diagnostics | Select when system already has host MCU and needs only high-channel-count ADC with ultra-low noise |
| R5F523E5AGFL#30 | Same package and temp grade, but 128 KB flash / 16 KB RAM / 1 DSAD unit instead of 2 | Reduced memory and single DSAD limit multi-sensor concurrent acquisition and complex calibration algorithms | Select for cost-sensitive single-sensor applications where dual DSAD and 256 KB flash are unnecessary |
Compared with ADS131M04IPBSR, R5F523E6AGFL#10 integrates processing, analog front end, and diagnostics in one chip-reducing PCB area by ≥35% and eliminating inter-IC timing alignment. Against R5F523E5AGFL#30, it doubles DSAD capability and memory for advanced sensor fusion, justifying the upgrade in multi-parameter transmitters.

FAQ
What is the maximum operating temperature specification for R5F523E6AGFL#10?
R5F523E6AGFL#10 is rated for operation from –40°C to +105°C (G-grade), validated per Renesas qualification standards. This extended temperature range supports deployment in harsh industrial environments such as motor control cabinets, outdoor process transmitters, and engine bay sensing modules where ambient heat exceeds standard commercial limits. The on-chip temperature sensor (±5°C accuracy) and low-drift analog blocks maintain performance across this full range.
Does R5F523E6AGFL#10 support simultaneous sampling across both 24-bit delta-sigma ADC units?
Yes, R5F523E6AGFL#10 supports inter-unit synchronized A/D conversion start via hardware trigger-enabling true simultaneous sampling of two independent sensor channels. This capability is critical for coherent phase measurements (e.g., current/voltage in energy meters) or correlated multi-parameter acquisition (e.g., strain + temperature in structural health monitoring), and is implemented without CPU intervention using the Event Link Controller (ELC).
How many excitation current sources does R5F523E6AGFL#10 provide, and what are their key specifications?
R5F523E6AGFL#10 provides four independent excitation current sources (IEXC0–IEXC3) with programmable output from 50 µA to 1000 µA in discrete steps. Key specs include ±0.2% current matching between channels and 5 ppm/°C drift matching-enabling precise 3-/4-wire RTD and resistive bridge measurements without external trimming. Each source can be individually enabled/disabled and routed to AIN pins via the analog multiplexer.
What communication interfaces are available on R5F523E6AGFL#10 for industrial connectivity?
R5F523E6AGFL#10 includes CAN 2.0B (1 Mbps), three SCIg channels (asynchronous/clock-sync/Smart Card), one SCIh channel (LIN-compatible), one I2C bus interface (400 kbps, SMBus-ready), and one RSPI channel (16 Mbps). These interfaces support direct connection to PLCs, HART modems, sensor networks, and local displays-eliminating need for protocol translation bridges in field instrumentation designs.
Is R5F523E6AGFL#10 qualified for IEC60730 Class B compliance?
R5F523E6AGFL#10 includes dedicated hardware features to support IEC60730 Class B compliance, including RAM test assistance via DOC, A/D converter self-diagnostic functions, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with disconnect detection, and analog input/reference fault detectors. These are documented in the R01DS0330EJ0130 datasheet and enable certified safety firmware implementation without external supervision ICs.
