Product details
Overview
R5F523E6MGFM#50 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement, integrating a 24-bit delta-sigma ADC (31.25 kSPS max), ±5-V analog input range, 256 KB flash, 32 KB SRAM, CAN interface, and on-chip excitation current sources. It operates at up to 32 MHz, supports –40°C to +105°C, and targets load cell, pressure sensor, and weigh scale systems requiring low-drift analog front-end performance.
For engineers reviewing the R5F523E6MGFM#50 datasheet, R5F523E6MGFM#50 pinout, R5F523E6MGFM#50 application, or R5F523E6MGFM#50 equivalent, key selection criteria include its 31.25 kSPS delta-sigma ADC sampling rate, 5-V analog input range, 64-pin LFQFP package with no LCD driver, G-grade temperature rating, and integrated programmable gain instrumentation amplifier with rail-to-rail operation.
Technical Context
The R5F523E6MGFM#50 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 5-stage Harvard pipeline, and memory protection unit-enabling deterministic real-time control in safety-critical industrial applications. Its analog subsystem centers on a single 24-bit delta-sigma A/D converter with fourth- and fifth-order sinc filtering, ±5-V HVAIN inputs, and hardware-assisted disconnect detection.
Clock management includes PLL, main/sub oscillators, and CAC for frequency accuracy monitoring; power management supports deep sleep and software standby modes with LPT operation. The ELC enables event-triggered peripheral coordination without CPU wake-up, critical for low-power sensor node operation.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MGFM#50?
The R5F523E6MGFM#50 supports a maximum delta-sigma ADC sampling rate of 31.25 kSPS. This rate is achieved with a 4 MHz modulator clock and applies to configurations using fourth-order sinc filtering. Lower rates (e.g., 10 SPS or 54 SPS) enable simultaneous 50/60 Hz rejection for AC-coupled industrial environments.
Does R5F523E6MGFM#50 include an LCD controller?
No, the R5F523E6MGFM#50 does not include an LCD controller. Per Renesas' part numbering scheme, the "M" suffix indicates a variant with 31.25 kSPS DSAD sampling and ±5-V analog input range but no LCD driver. Models with LCD support use suffixes "J", "L", or "N".
What is the operating temperature range specified for R5F523E6MGFM#50?
The R5F523E6MGFM#50 is rated for operation from –40°C to +105°C (G-grade). This extended temperature range is validated per Renesas' industrial qualification standards and supports deployment in motor control cabinets, outdoor process analyzers, and factory automation equipment.
Can R5F523E6MGFM#50 drive load cells directly without external amplification?
Yes, the R5F523E6MGFM#50 can interface directly with most bridge-type load cells. Its integrated rail-to-rail programmable gain instrumentation amplifier (PGA) supports gains from ×1 to ×128, and the ±5-V HVAIN pins accept typical 2–3 mV/V full-scale outputs without external op-amps or level-shifting circuitry.
How many excitation current sources does R5F523E6MGFM#50 provide, and what is their matching accuracy?
The R5F523E6MGFM#50 integrates two independent excitation current sources (IEXC0 and IEXC1), each programmable from 50 µA to 1000 µA in discrete steps. Their current matching is specified at ±0.2%, and drift matching is 5 ppm/°C-critical for stable ratiometric measurements in precision bridge sensor applications.
