Product details
Overview
R5F523E6SGNF#20 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision analog sensing, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (PGA ×2), 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and integrated CAN 2.0B interface - all in a 40-pin HWQFN (6 × 6 mm, 0.5 mm pitch) package rated for –40°C to +105°C operation.
For engineers reviewing the R5F523E6SGNF#20 datasheet, R5F523E6SGNF#20 pinout, R5F523E6SGNF#20 application, or R5F523E6SGNF#20 equivalent, this device delivers calibrated 23-bit effective resolution at 7.6 SPS, simultaneous 50/60 Hz rejection, on-chip self-diagnostic support for IEC 60730 compliance, and ELC-triggered synchronized A/D conversion - critical for industrial temperature, pressure, and load-cell measurement systems requiring metrology-grade accuracy and functional safety.
Technical Context
The R5F523E6SGNF#20 implements a dedicated analog front-end architecture with two independent 24-bit delta-sigma A/D converters, each with fourth-order sinc filtering, programmable PGA (×1 to ×128), and configurable differential/single-ended inputs (6 channels per unit). Its analog subsystem includes excitation current sources with ±0.2% matching and 5 ppm/°C drift, bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), and low-side switch (10 Ω max) for sensor excitation control.
Digital execution is handled by a 32 MHz RXv2 CPU with IEEE 754-compliant FPU, memory protection unit (MPU), and event-link controller (ELC) enabling interrupt-free peripheral coordination - allowing synchronized DSAD conversion start, MTU waveform generation, and CAN message transmission while the CPU remains in deep sleep mode.

The R5F523E6SGNF#20 features two 24-bit delta-sigma A/D converters with up to 23-bit effective resolution at 7.6 SPS in normal mode. In low-power mode, resolution remains high (22-bit typical) at 1.9 SPS. Oversampling ratios range from 32 to 65536 (multiples of 16), and sinc4 filtering enables simultaneous 50 Hz/60 Hz rejection at specific output data rates like 10 and 54 SPS.
Does R5F523E6SGNF#20 support IEC 60730 Class B compliance out of the box?
Yes, the R5F523E6SGNF#20 includes hardware-assisted self-test features required for IEC 60730 Class B, including DSAD offset/gain calibration, reference voltage fault detection, excitation current source disconnect detection, RAM test assistance via DOC, and independent watchdog timer (IWDT) with dedicated oscillator - all documented in Renesas Application Note R01AN3913.
What are the key differences between R5F523E6SGNF#20 and R5F523E6ADNF#20?
The R5F523E6SGNF#20 and R5F523E6ADNF#20 share identical memory (256 KB flash, 32 KB RAM), dual 24-bit DSAD units, and 40-pin HWQFN packaging. The primary difference is operating temperature grade: R5F523E6SGNF#20 is G-grade (–40°C to +105°C), while R5F523E6ADNF#20 is D-grade (–40°C to +85°C). Both support the same analog and communication peripherals.
Can R5F523E6SGNF#20 perform synchronized A/D conversion across both delta-sigma units?
Yes, the R5F523E6SGNF#20 supports inter-unit synchronized A/D conversion start via the Event Link Controller (ELC). This allows precise phase-aligned sampling across both DSAD0 and DSAD1 units - essential for multi-sensor coherence in applications like 3-phase current monitoring or differential bridge measurements.
What excitation current settings and matching specifications does R5F523E6SGNF#20 provide?
The R5F523E6SGNF#20 provides four excitation current sources (IEXC0–IEXC3) with programmable output from 50 µA to 1000 µA in six discrete steps. Current matching is ±0.2% between channels, and drift matching is 5 ppm/°C - enabling high-accuracy ratiometric measurements for RTDs, strain gauges, and other resistive sensors.
