Product details
Overview
R5F523E6AGNF#40 from Renesas is a 32-bit RXv2 microcontroller 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 gain ×1 to ×128), 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 32 MHz with 256 KB flash, 32 KB SRAM, and supports –40°C to +105°C ambient temperature.
For engineers reviewing the R5F523E6AGNF#40 datasheet, R5F523E6AGNF#40 pinout, R5F523E6AGNF#40 application, or R5F523E6AGNF#40 equivalent, this MCU targets precision analog measurement in harsh environments-especially thermocouple, RTD, and strain gauge systems requiring simultaneous high-resolution conversion, on-chip calibration, and functional safety support per IEC 60730.
Technical Context
The R5F523E6AGNF#40 implements a CISC Harvard architecture with 5-stage pipeline, 32-bit RXv2 CPU core, and IEEE 754-compliant single-precision FPU. Its analog subsystem integrates two independent 24-bit delta-sigma A/D converters, each with fourth-order sinc filtering, programmable data rates (1.9–15.6 kSPS), and simultaneous 50/60 Hz rejection at 10/54 SPS.
Digital peripherals include one CAN module (ISO 11898-1, up to 1 Mbps), three SCIg channels (asynchronous/clock-sync/Smart Card), one RIIC (400 kbps), one RSPI (16 Mbps), and event-driven operation via ELC-enabling low-power synchronized peripheral triggering without CPU wake-up.
