Product details
Overview
R5F523E6LGFP#30 from Renesas is a 32-bit RXv2 MCU optimized for high-precision industrial sensing and measurement, featuring a 24-bit delta-sigma A/D converter with ±10-V input capability, 125 kSPS max sampling rate, 256 KB on-chip flash, 32 KB SRAM, and integrated programmable gain instrumentation amplifier (PGA) with 11 nVRMS noise at gain = 128. It operates up to 32 MHz and supports CAN, SCI, I²C, and RSPI interfaces in a 100-pin LFQFP package.
For engineers reviewing the R5F523E6LGFP#30 datasheet, R5F523E6LGFP#30 pinout, R5F523E6LGFP#30 application, or R5F523E6LGFP#30 equivalent, this device is selected for high-accuracy analog front-end integration in energy metering, strain gauge readout, load cell interfaces, and industrial process controllers requiring simultaneous 50/60 Hz rejection and low-drift voltage reference (2.5 V, 8 ppm/°C).
Technical Context
The R5F523E6LGFP#30 integrates a dedicated analog subsystem centered on the DSADB 24-bit delta-sigma ADC, synchronized to PCLKC (up to 16 MHz), with four selectable sinc filter configurations and hardware-assisted disconnect detection for HVAIN pins. Its dual A/D architecture pairs the high-resolution DSADB with an 8-channel 12-bit S12ADE (1.4 µs conversion) for fast control-loop feedback.
Real-time signal processing is enabled by the RXv2 CPU core (64 DMIPS @ 32 MHz), FPU (IEEE 754 single-precision), and event-driven ELC that triggers ADC conversions, PWM updates, or DMA transfers without CPU intervention-critical for deterministic timing in closed-loop systems.

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 |
|---|---|---|---|

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6LGFP#30?
The R5F523E6LGFP#30 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achievable with modulator clock fMOD = 4 MHz and appropriate sinc filter selection. At lower data rates (e.g., 10 or 54 SPS), the device provides simultaneous 50/60 Hz rejection for clean AC-line–immunity measurements.
Does R5F523E6LGFP#30 support ±10-V analog inputs, and how are they implemented?
Yes, the R5F523E6LGFP#30 supports ±10-V differential analog inputs via dedicated HVAIN0–HVAIN3 pins. These pins are internally protected and routed to the 24-bit delta-sigma ADC's analog multiplexer. The ±10-V range is enabled by internal level-shifting circuitry and requires AVCC0 = 4.5–5.5 V for full specification compliance.
What is the role of the excitation current sources (IEXC0/IEXC1) in R5F523E6LGFP#30?
The R5F523E6LGFP#30 integrates two precision excitation current sources (IEXC0/IEXC1) with programmable output (50–1000 µA), ±0.2% matching, and 5 ppm/°C drift. They are used to bias 2-/3-/4-wire RTDs, bridge sensors, or other current-driven transducers - enabling ratiometric measurements that cancel supply variation errors.
Can R5F523E6LGFP#30 operate in functional safety–certified systems per IEC 60730?
Yes, the R5F523E6LGFP#30 includes hardware-assisted self-diagnostic features for IEC 60730 compliance: ADC self-test, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM test via DOC, and analog input disconnect detection - reducing software validation burden for Class B safety applications.
What package type and pin count does R5F523E6LGFP#30 use?
The R5F523E6LGFP#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 mm × 14 mm body size, 0.5 mm pin pitch, and exposed thermal pad. This package supports full peripheral access including all 8 DSADB differential inputs, CAN, and multiple SCI channels.
