Product details
Overview
R5F523E6NGBS#20 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial analog sensing, featuring a 24-bit delta-sigma A/D converter with 31.25 kSPS max sampling rate, ±5-V analog input range, 256-KB on-chip flash, 32-KB SRAM, and integrated programmable gain instrumentation amplifier (PGA) with rail-to-rail operation. It operates at up to 32 MHz across –40°C to +105°C and supports CAN, SCI, I²C, and RSPI interfaces - deployed in smart sensor nodes and precision metering systems.
For engineers reviewing the R5F523E6NGBS#20 datasheet, R5F523E6NGBS#20 pinout, R5F523E6NGBS#20 application, or R5F523E6NGBS#20 equivalent, this MCU delivers verified 24-bit ADC performance at 31.25 kSPS with ±5-V input capability, on-chip excitation current sources (50–1000 µA), low-drift voltage reference (2.5 V, 8 ppm/°C), and real-time calibration support for IEC60730-compliant designs.
Technical Context
The R5F523E6NGBS#20 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU). Its analog subsystem centers on the DSADB module - a dedicated 24-bit delta-sigma A/D converter synchronized to PCLKC (≤16 MHz), supporting fourth- and fifth-order sinc filters, simultaneous 50/60 Hz rejection, and PGA gain settings from ×1 to ×128.
Digital integration includes a 1-channel CAN controller (ISO 11898-1, up to 1 Mbps), 6-channel SCIg, 1-channel RIICa (I²C/SMBus), and ELC-driven event-triggered conversion - enabling low-CPU-overhead sensor acquisition while the core sleeps in deep sleep mode using the LPT timer.

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 |
|---|---|---|---|
| R5F523E6LGBS#20 | Same package and core, but supports ±10-V analog input range and includes LCD driver. | Required for applications needing direct ±10-V sensor interfacing or on-module display (e.g., panel meters). | Select R5F523E6LGBS#20 only if ±10-V input or LCD functionality is mandatory; otherwise R5F523E6NGBS#20 offers optimal cost/performance for ±5-V systems. |
| ADS131M04IPBSR | Dedicated 24-bit delta-sigma ADC (no MCU), 64 kSPS, SPI interface, ±2.5-V input - requires external host processor. | Suitable when analog acquisition is isolated from control logic (e.g., modular sensor heads with separate MCU). | Choose ADS131M04IPBSR only for distributed architectures where ADC and processing are physically separated; R5F523E6NGBS#20 integrates both with deterministic timing. |
Compared with R5F523E6LGBS#20, R5F523E6NGBS#20 reduces system cost by omitting unused ±10-V input circuitry and LCD driver, while maintaining identical 24-bit ADC performance at ±5-V range; versus ADS131M04IPBSR, it eliminates inter-IC communication latency and external firmware development for sensor calibration and safety checks.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6NGBS#20?
The R5F523E6NGBS#20 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma A/D converter. This rate is achieved with specific filter configurations (e.g., fourth-order sinc) and modulator clock settings. At lower data rates such as 10 or 54 SPS, the device provides simultaneous 50 Hz/60 Hz rejection - critical for AC-line-immune industrial sensing. The R5F523E6NGBS#20 does not support the 125 kSPS mode found in 'L' and 'K' variants.
Does R5F523E6NGBS#20 include an integrated voltage reference, and what are its specifications?
Yes, the R5F523E6NGBS#20 includes an on-chip voltage reference with a nominal output of 2.5 V, temperature drift of 8 ppm/°C over –40°C to +85°C, and ±10 mA output current capability. This reference is used by the 24-bit delta-sigma ADC and 16-bit DAC, and supports external bypassing for enhanced stability. The R5F523E6NGBS#20 also allows selection of external reference inputs for the DSAD module, with built-in fault detection for disconnection or overvoltage.
Can R5F523E6NGBS#20 operate in extended temperature environments, and what is its qualification grade?
Yes, the R5F523E6NGBS#20 is the G-version part, qualified for operation from –40°C to +105°C ambient temperature. It is designed for under-hood automotive, industrial control, and energy infrastructure applications where thermal resilience is required. The device undergoes full characterization across this range for all analog peripherals - including the PGA (offset drift 4 nV/°C), excitation current sources (matching ±0.2%), and voltage reference (8 ppm/°C).
How many excitation current sources does R5F523E6NGBS#20 provide, and what are their key electrical characteristics?
The R5F523E6NGBS#20 integrates two independent excitation current sources (IEXC0 and IEXC1), each programmable from 50 µA to 1000 µA in discrete steps. Key specs include current matching of ±0.2% between channels and drift matching of 5 ppm/°C - essential for ratiometric measurements in 3- or 4-wire RTD and strain gauge applications. These sources are fully integrated into the analog multiplexer and support disconnect detection.
Is R5F523E6NGBS#20 pin-compatible with other RX23E-B group MCUs in the same package?
No, R5F523E6NGBS#20 is not universally pin-compatible across all RX23E-B variants - compatibility depends on package type and feature enablement. In the PTBG0100KD-A (100-pin TFBGA) package, R5F523E6NGBS#20 shares identical pinout with R5F523E6LGBS#20 and R5F523E5NGBS#20, as confirmed in Table 1.2 of the datasheet. However, functional differences (e.g., LCD driver presence or HVAIN count) mean that software and peripheral initialization must be validated per part number.
