Product details
Overview
R5F523E5NGBS#00 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing applications, featuring a 32-MHz CPU core, 128-KB on-chip flash, 16-KB SRAM, 8-KB data flash, and a 24-bit delta-sigma A/D converter with 31.25 kSPS sampling rate and ±5-V input range. It integrates rail-to-rail programmable gain instrumentation amplifiers (gain = 1–128), excitation current sources (50–1000 µA), low-drift voltage reference (2.5 V, 8 ppm/°C), and CAN 2.0B interface compliant to ISO11898-1.
For engineers reviewing the R5F523E5NGBS#00 datasheet, R5F523E5NGBS#00 pinout, R5F523E5NGBS#00 application, or R5F523E5NGBS#00 equivalent, key selection criteria include its G-grade (–40°C to +105°C) operation, TFBGA-100 package with 0.5-mm pitch, integrated analog front-end for load cell/RTD/thermocouple interfaces, and support for IEC60730 safety compliance via self-diagnostic functions.
Technical Context
The R5F523E5NGBS#00 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 64 DMIPS at 32 MHz, and memory protection unit (MPU) for secure embedded execution. Its analog subsystem centers on the DSADB module - a 24-bit delta-sigma ADC with fourth- and fifth-order sinc filters, ±5-V HVAIN inputs, and simultaneous 50/60 Hz rejection at 10/54 SPS.
Digital integration includes one CAN channel (up to 1 Mbps), six SCIg interfaces (asynchronous/clock-synchronous/smart card), one RIIC (I²C/SMBus), one RSPI (16 Mbps), four-channel DMAC, ELC for interrupt-free peripheral chaining, and LPT for wake-up during software standby. Clock management supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL, and IWDT-dedicated oscillator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5NDFP | Same core/peripherals but LFQFP-100 package (14 × 14 mm), D-grade (–40°C to +85°C), no TFBGA footprint | Preferred for prototyping or legacy PCBs requiring larger pitch and easier rework; lacks G-grade thermal margin | Select when board space allows 14 × 14 mm footprint and ambient temperature stays ≤85°C. |
| R5F523E5NGFN | 80-pin LFQFP package (12 × 12 mm), same G-grade temp, reduced I/O count (43 pins), no RTC, 6-channel DSAD instead of 8 | Suitable for cost-sensitive designs where RTC and full analog channel count are non-critical | Choose when system requires only 6 differential sensor inputs and can omit real-time clock functionality. |
Compared with R5F523E5NGBS#00, R5F523E5NDFP offers identical analog performance in a more serviceable package but sacrifices extended temperature operation, while R5F523E5NGFN reduces pin count and analog channel capacity to lower BOM cost-neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E5NGBS#00?
The R5F523E5NGBS#00 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achieved with modulator clock fMOD = 4 MHz and applies to configurations using the fourth-order sinc filter. Lower rates (e.g., 10 SPS or 54 SPS) enable simultaneous 50/60 Hz rejection for AC-line-immune measurements.
Does R5F523E5NGBS#00 include an integrated voltage reference, and what is its accuracy?
Yes, R5F523E5NGBS#00 includes an on-chip voltage reference (VREF) with nominal output of 2.5 V, temperature drift of 8 ppm/°C over –40°C to +85°C, and output current capability of ±10 mA. This reference is used by the 24-bit delta-sigma ADC and can also be routed externally for system-level calibration.
Can R5F523E5NGBS#00 drive a 4-wire RTD directly, and how is current matching ensured?
Yes, R5F523E5NGBS#00 integrates two excitation current sources (IEXC0/IEXC1) configurable from 50 µA to 1000 µA. Current matching is specified at ±0.2%, and drift matching is 5 ppm/°C - enabling high-accuracy 4-wire RTD measurements meeting IEC60751 Class A requirements without external precision current sources.
What safety certifications or built-in functions does R5F523E5NGBS#00 support for IEC60730 compliance?
R5F523E5NGBS#00 provides hardware-assisted IEC60730 compliance features including delta-sigma ADC input disconnect detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) diagnostics, RAM test assistance via Data Operation Circuit (DOC), and analog input fault detection - reducing software validation burden for Class C safety applications.
Is the R5F523E5NGBS#00 pin-compatible with other members of the RX23E-B Group, such as R5F523E5LGBS#00?
No, R5F523E5NGBS#00 is not pin-compatible with R5F523E5LGBS#00 despite sharing the same TFBGA-100 package. The 'N' variant uses ±5-V analog input range and excludes LCD driver circuitry, while the 'L' variant supports ±10-V inputs and includes LCD controller - resulting in different HVAIN pin assignments and functional pin multiplexing.
