Product details
Overview
R5F523E6NDFP#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). The MCU operates at up to 32 MHz, includes 256 KB flash, 32 KB SRAM, and supports CAN, SCI, I²C, and RSPI interfaces.
For engineers reviewing the R5F523E6NDFP#10 datasheet, R5F523E6NDFP#10 pinout, R5F523E6NDFP#10 application, or R5F523E6NDFP#10 equivalent, this device is selected for embedded metering, load cell interface, and precision sensor signal conditioning where simultaneous high-resolution analog acquisition, low-drift reference stability, and real-time control coexist on a single chip.
Technical Context
The R5F523E6NDFP#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) - enabling deterministic real-time execution of sensor fusion and calibration algorithms. Its analog subsystem centers on the DSADB module, synchronized to PCLKC (≤16 MHz), with configurable sinc filters and ELC-triggered conversion for deterministic timing without CPU intervention.
Power management includes three low-power modes (sleep, deep sleep, software standby), LPT operation during standby, and independent voltage detection circuits (LVDAb) with 14-level programmability. Clock architecture supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL, and dedicated IWDT oscillator - all monitored by CAC for IEC 60730 compliance.

|---|---|
Use Scenario: High-accuracy platform scale measuring 0.1 g resolution over 100 kg range using full-bridge load cells.

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 |
|---|---|---|---|
| R5F523E6LDFP#10 | Same package and memory, but supports ±10-V analog input range and 125 kSPS sampling - higher dynamic range and speed | Suitable for applications requiring wider input range (e.g., industrial voltage monitoring) or faster acquisition (e.g., vibration analysis) | Select R5F523E6LDFP#10 when ±10-V input or >31.25 kSPS sampling is required; otherwise R5F523E6NDFP#10 offers optimal cost/performance for ±5-V sensor interfaces. |
| R5F523E5NDFP#10 | 128 KB flash / 16 KB SRAM / same analog specs - reduced memory footprint and lower cost | Targeted at cost-sensitive designs with simpler firmware (e.g., basic sensor nodes without complex algorithms or OTA updates) | Choose R5F523E5NDFP#10 for volume production where 128 KB flash suffices and BOM cost reduction is prioritized over future firmware scalability. |
Compared with R5F523E6LDFP#10, R5F523E6NDFP#10 trades ±10-V input and 125 kSPS capability for lower system cost and identical thermal performance in ±5-V applications; versus R5F523E5NDFP#10, it provides double flash/SRAM for advanced calibration, security, and field-upgrade features without changing PCB layout.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6NDFP#10?
The R5F523E6NDFP#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 appropriate sinc filter configuration. At lower rates (e.g., 10 or 54 SPS), the device provides simultaneous 50/60 Hz rejection - a key capability for noise-immune industrial measurements. The R5F523E6NDFP#10 does not support the 125 kSPS mode found in L- and K-suffix variants.
Does R5F523E6NDFP#10 include an integrated voltage reference, and what is its accuracy?
Yes, the R5F523E6NDFP#10 integrates a 2.5-V voltage reference with ±8 ppm/°C temperature drift over the full operating range (–40°C to +85°C) and ±10 mA output capability. This reference is used internally by the 24-bit delta-sigma ADC and can also be routed externally. Its low drift ensures stable ADC performance without requiring external trimming or recalibration across temperature - a critical feature for certified industrial instrumentation.
Can R5F523E6NDFP#10 drive RTD sensors directly, and how many channels does it support?
Yes, the R5F523E6NDFP#10 includes two integrated excitation current sources (IEXC0 and IEXC1), each programmable from 50 µA to 1000 µA with ±0.2% matching and 5 ppm/°C drift matching. These support direct 2-, 3-, or 4-wire RTD measurements. The analog multiplexer (AMUX) routes excitation and sense signals to the 24-bit delta-sigma ADC inputs, enabling fully integrated RTD signal conditioning without external current sources or precision resistors.
What communication interfaces are available on R5F523E6NDFP#10 for industrial networking?
The R5F523E6NDFP#10 integrates one ISO 11898-1-compliant CAN channel (RSCAN) supporting up to 1 Mbps, six SCIg channels (asynchronous/clock-synchronous/smart card), one SCIh channel (LIN-capable), one I²C bus interface (400 kbps, SMBus compatible), and one RSPI channel (16 Mbps). These interfaces enable robust connectivity to PLCs, HMIs, and fieldbus gateways - with CAN and LIN support simplifying integration into existing industrial networks.
Is R5F523E6NDFP#10 qualified for functional safety standards like IEC 60730?
Yes, the R5F523E6NDFP#10 includes hardware-assisted self-test features required for Class B compliance per IEC 60730: built-in diagnostic support for the 24-bit ADC (offset/gain calibration, disconnect detection), clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance (via DOC), and analog voltage detectors. These reduce software validation effort and accelerate certification for household and industrial appliances.
