Product details
Overview
R5F523E6AGFL#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensor measurement, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (gain = 1–128), 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and 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 R5F523E6AGFL#30 datasheet, R5F523E6AGFL#30 pinout, R5F523E6AGFL#30 application, or R5F523E6AGFL#30 equivalent, this MCU targets high-accuracy analog front-end designs requiring simultaneous multi-channel sigma-delta conversion, on-chip excitation, and real-time control in harsh thermal environments - especially thermocouple, RTD, and strain gauge systems compliant with IEC 60730 Class B.
Technical Context
The R5F523E6AGFL#30 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, programmable data rates (1.9–15625 SPS), and simultaneous 50/60 Hz rejection at 10/54 SPS. Each DSAD unit supports up to six differential inputs and includes offset/gain calibration, disconnect detection assist, and external reference voltage input.
Its analog subsystem includes a rail-to-rail PGA (30 nVRMS noise @ gain=128), bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), low-side switch (10 Ω max), and voltage fault detectors for AVCC0, reference inputs, and excitation outputs - all synchronized via the Event Link Controller (ELC) for deterministic timing without CPU intervention.
