Product details
Overview
R5F523E5NDFP#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 input range, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), on-chip excitation current sources (50–1000 µA), and 2.5-V low-drift voltage reference (8 ppm/°C). Operating at up to 32 MHz, it delivers 64 DMIPS and includes CAN, SCI, I²C, and RSPI interfaces.
For engineers reviewing the R5F523E5NDFP#10 datasheet, R5F523E5NDFP#10 pinout, R5F523E5NDFP#10 application, or R5F523E5NDFP#10 equivalent, key selection criteria include its 31.25 kSPS delta-sigma ADC performance at ±5 V full-scale, integrated PGA and excitation sources for bridge sensor conditioning, CAN interface compliance with ISO 11898-1, and support for IEC 60730 safety diagnostics including RAM test assistance and A/D self-diagnostic functions.
Technical Context
The R5F523E5NDFP#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE 754-compliant 32-bit FPU - enabling real-time floating-point computation for sensor linearization and compensation algorithms. Its analog subsystem centers on the DSADB unit, synchronized to PCLKC (≤16 MHz), with configurable sinc filters and simultaneous 50/60 Hz rejection at 10/54 SPS.
Digital peripheral coordination is managed by the Event Link Controller (ELC), allowing autonomous trigger routing (e.g., MTU timer → DSAD conversion start) without CPU intervention, while the 4-channel DMAC and DTC offload data movement from the 24-bit ADC output buffers to SRAM or flash. Power management includes three low-power modes and a software standby state sustained by the LPT running from the 32.768-kHz sub-clock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog measurement MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5LDFP#10 | Same package and core, but supports ±10-V analog input range and 125 kSPS sampling rate | Required for higher-voltage sensor interfaces (e.g., 10-V strain gauges) and faster acquisition needs | Select when full-scale input exceeds ±5 V or >31.25 kSPS sampling is needed; otherwise R5F523E5NDFP#10 offers optimal cost/performance for ±5-V industrial sensors |
| ADUCM360BCPZ-RL7 | ARM Cortex-M3 core, 24-bit ΣΔ ADC (3.75–3900 SPS), integrated 4-mA loop driver, no CAN or ELC | Targeted at 4–20 mA loop-powered transmitters; lacks event-driven autonomy and industrial networking | Choose for loop-powered field devices where low quiescent current and DAC+driver integration outweigh need for CAN or complex timing coordination |

The R5F523E5NDFP#10 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma ADC. This rate is achieved with fMOD = 4 MHz and applies to configurations using fourth-order sinc filtering. Lower rates (e.g., 10 SPS or 54 SPS) enable simultaneous 50 Hz/60 Hz rejection. The R5F523E5NDFP#10 does not support the 125 kSPS mode found in 'L' or 'K' variants.
Does the R5F523E5NDFP#10 include a CAN interface, and what standard does it comply with?
Yes, the R5F523E5NDFP#10 integrates one channel of the RSCAN CAN module compliant with ISO 11898-1 for standard and extended frames, supporting bit rates up to 1 Mbps. It includes 16 message boxes and supports loopback, self-test, and error counters - making it suitable for industrial fieldbus communication in distributed control systems.

The R5F523E5NDFP#10 supports a ±5-V analog input range on its HVAIN pins, as indicated by the 'N' suffix in its part number per Renesas' naming convention. It does not support the ±10-V range offered by 'L' or 'K' variants. This range is optimized for common industrial bridge sensors and strain gauges operating with 5-V excitation.
How does the R5F523E5NDFP#10 support functional safety standards like IEC 60730?
The R5F523E5NDFP#10 includes hardware-assisted features for IEC 60730 Class B compliance: A/D converter self-diagnostic, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with disconnect detection, RAM test assistance via the Data Operation Circuit (DOC), and voltage detector circuits for analog supply monitoring - all documented in the device's safety manual.
What is the operating temperature range specified for the R5F523E5NDFP#10?
The R5F523E5NDFP#10 is rated for an operating ambient temperature range of –40°C to +85°C, denoted by the 'D' suffix in its part number. This industrial-grade rating ensures reliable operation in factory automation, process control, and outdoor equipment environments without derating.
