Product details
Overview
R5F523E5AGNF#40 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog sensing in industrial measurement systems. It integrates two 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (gain = 1–128), a 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and a CAN 2.0B interface - all operating at up to 32 MHz with 128 KB flash, 16 KB SRAM, and 8 KB data flash.
For engineers reviewing the R5F523E5AGNF#40 datasheet, R5F523E5AGNF#40 pinout, R5F523E5AGNF#40 application, or R5F523E5AGNF#40 equivalent, this MCU targets high-accuracy sensor signal conditioning where simultaneous multi-channel delta-sigma conversion, on-chip excitation control, and real-time CAN bus communication are required in compact, thermally stable designs.
Technical Context
The R5F523E5AGNF#40 implements a CISC Harvard architecture RXv2 CPU core with IEEE 754-compliant 32-bit FPU, memory protection unit (MPU), and fast interrupt response. Its analog subsystem features dual 24-bit delta-sigma ADCs with fourth-order sinc filters, selectable normal/low-power modes (7.6–15625 SPS), and simultaneous 50/60 Hz rejection at 10/54 SPS.
Digital integration includes a 1-channel CAN module compliant with ISO 11898-1 (up to 1 Mbps), three SCI interfaces (SCI1/5/6), one I²C bus interface (400 kbps), one RSPI (16 Mbps), and event-link controller (ELC) enabling peripheral-triggered operation without CPU wake-up - critical for low-power sensor node operation.

Applications
| Industrial Weigh Scales | High-Accuracy Temperature Monitoring |
|---|---|
Use Scenario: Precision weighing of industrial loads using strain-gauge bridges under varying ambient conditions.

Use Value: Achieves ≤0.005% full-scale accuracy with integrated 24-bit conversion, temperature-compensated reference, and matched excitation - eliminating external precision DACs and op-amps. |
Use Scenario: Multi-point resistance temperature detector (RTD) monitoring in process control cabinets with long cable runs. IC Role / Device Role / Timing Role: Sensor interface MCU: drives 4-wire RTDs with programmable IEXC, measures ΔV across precision sense resistors, rejects 50/60 Hz noise digitally, and reports compensated temperature via SCI/CAN. Use Value: Enables direct 4-wire RTD connection with <±0.1°C accuracy over –40°C to +105°C, leveraging on-chip excitation matching (±0.2%) and low-drift VREF (10 ppm/°C). |

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 |
|---|---|---|---|
| TI MSP430F67791A | 16-bit CPU, single 24-bit sigma-delta ADC (7-ch), no integrated CAN, lower max clock (25 MHz) | Limited to single-sensor nodes; requires external CAN transceiver and external excitation circuitry | Prefer when ultra-low power (<1 µA RTC mode) outweighs CAN integration and dual-ADC concurrency |
| ST STM32G474RE | 32-bit Arm Cortex-M4F, dual 16-bit SAR ADCs (not delta-sigma), no integrated excitation sources, 12-bit DACs instead of PGA | Suitable for medium-accuracy control loops but lacks the 24-bit ENOB, low-noise PGA, and matched IEXC needed for RTD/strain gauge metrology | Prefer when floating-point control algorithms dominate over ultra-high-resolution analog capture |
Compared with MSP430F67791A and STM32G474RE, the R5F523E5AGNF#40 uniquely combines dual 24-bit delta-sigma conversion, rail-to-rail PGA, four matched excitation sources, and ISO 11898-1 CAN in a single G-grade package - enabling certified Class 0.1 industrial sensor nodes without analog signal chain compromises.

Its rail-to-rail programmable gain instrumentation amplifier achieves 30 nVRMS input-referred noise at gain = 128 and exhibits 10 nV/°C offset drift and 1 ppm/°C gain drift - specifications explicitly guaranteed for the R5F523E5AGNF#40 across its –40°C to +105°C operating range per the device's datasheet.
How many excitation current sources does the R5F523E5AGNF#40 provide, and what are their accuracy specs?
The R5F523E5AGNF#40 provides four independent excitation current sources (IEXC0–IEXC3) with programmable output from 50 µA to 1000 µA. These sources guarantee ±0.2% current matching between channels and 5 ppm/°C drift matching - enabling precise 3- and 4-wire RTD measurements without external calibration. These specs are validated for the R5F523E5AGNF#40 in the "Analog Front End" section of the official Renesas datasheet.
Is the R5F523E5AGNF#40 qualified for extended temperature operation, and what package does it use?
Yes, the R5F523E5AGNF#40 is rated for –40°C to +105°C operation (G-grade) and uses the 40-pin HWQFN package (PWQN0040KD-A), measuring 6 × 6 mm with 0.5 mm pitch and an exposed thermal pad.
