Product details
Overview
R5F523E5SGNF#00 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor signal conditioning, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (PGA ×8 gain settings), 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and integrated CAN 2.0B interface. It operates at up to 32 MHz with 128 KB flash, 16 KB SRAM, and 8 KB data flash, targeting thermocouple and RTD measurement systems.
For engineers reviewing the R5F523E5SGNF#00 datasheet, R5F523E5SGNF#00 pinout, R5F523E5SGNF#00 application, or R5F523E5SGNF#00 equivalent, this page delivers verified technical context, package-specific pin mapping (40-pin HWQFN), real-world use cases in temperature sensing, and two validated alternative parts with documented functional and parametric differences.
Technical Context
The R5F523E5SGNF#00 implements a CISC Harvard architecture with 5-stage pipeline, supporting IEEE 754-compliant 32-bit floating-point operations and 32-bit multiply-accumulate DSP instructions. Its analog subsystem integrates two independent 24-bit delta-sigma ADCs with fourth-order sinc filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and offset/gain calibration per channel.
It features event-driven operation via the Event Link Controller (ELC), enabling synchronized A/D conversion start, timer triggering, and peripheral activation without CPU intervention - critical for low-power, deterministic sensor acquisition. The MCU supports IEC 60730 Class B compliance with built-in self-test functions for ADC, clock accuracy (CAC), IWDT, and RAM.
