Product details
Overview
R5F523E6LGFP#10 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement, featuring a 24-bit delta-sigma ADC 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#10 datasheet, R5F523E6LGFP#10 pinout, R5F523E6LGFP#10 application, or R5F523E6LGFP#10 equivalent, this MCU delivers calibrated analog front-end performance for load cell, strain gauge, and precision weight-scale systems - with built-in excitation current sources, voltage reference (2.5 V, 8 ppm/°C), and IEC60730 safety support for Class B compliance.
Technical Context
The R5F523E6LGFP#10 integrates a dedicated analog subsystem centered on the DSADB 24-bit delta-sigma ADC, synchronized to PCLKC (up to 16 MHz), with configurable sinc filters, simultaneous 50/60 Hz rejection, and ±10-V HVAIN inputs. Its RXv2 CPU core executes at 32 MHz with 64 DMIPS, includes single-precision FPU (IEEE 754), MPU, and ELC for interrupt-free peripheral coordination.
It supports three low-power modes (sleep, deep sleep, software standby), features a low-power timer (LPT) running off sub-clock or IWDT oscillator, and provides dual A/D converters: the high-resolution DSADB (8 differential channels) and an 8-channel 12-bit S12ADE with 1.4 µs conversion time - both supporting self-diagnostic and disconnect detection per IEC60730.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6LGFP#10?
The R5F523E6LGFP#10 features a DSADB 24-bit delta-sigma ADC with a maximum sampling rate of 125 kSPS. This rate is achievable at lower resolution settings and modulator clock frequencies; at full 24-bit effective resolution, the typical usable rate is 3.8 SPS with fourth-order sinc filtering and simultaneous 50/60 Hz rejection enabled.
Does R5F523E6LGFP#10 support ±10-V analog inputs, and how are they implemented?
Yes, the R5F523E6LGFP#10 supports ±10-V analog inputs via four dedicated HVAIN pins (HVAIN0–HVAIN3). These pins are electrically isolated from standard I/O domains and connect directly to the DSADB converter's input multiplexer, enabling direct interface with high-output bridge sensors without external level-shifting or amplification circuitry.
What IEC60730 safety features are integrated into R5F523E6LGFP#10?
The R5F523E6LGFP#10 includes hardware-assisted IEC60730 Class B compliance features: self-diagnostic routines for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the data operation circuit (DOC), and analog input disconnect detection for DSAD, reference voltage, and excitation current sources.
Can R5F523E6LGFP#10 operate in low-power modes while maintaining analog measurement capability?
Yes, the R5F523E6LGFP#10 supports three low-power modes - Sleep, Deep Sleep, and Software Standby - and retains key analog functionality in each. The low-power timer (LPT) continues operating in Software Standby mode, and the DSADB can be triggered via event signals (ELC) or software to perform background conversions without waking the CPU.
What is the purpose of the excitation current sources (IEXC0/IEXC1) in R5F523E6LGFP#10?
The R5F523E6LGFP#10 integrates two programmable excitation current sources (IEXC0 and IEXC1), each adjustable from 50 µA to 1000 µA in six steps, with ±0.2% matching and 5 ppm/°C drift matching. They are designed to bias 3-wire or 4-wire RTDs and resistive bridge sensors, eliminating the need for external current sources and improving system accuracy and thermal stability.
