Product details
Overview
R5F523E6MGFL#10 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision analog measurement in industrial sensor nodes and metering systems. It integrates a 24-bit delta-sigma ADC with 31.25 kSPS max sampling rate, ±5-V input range, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), on-chip excitation current sources (50–1000 µA), and 256 KB flash/32 KB SRAM - all operating at up to 32 MHz within a 48-pin LFQFP package.
For engineers reviewing the R5F523E6MGFL#10 datasheet, R5F523E6MGFL#10 pinout, R5F523E6MGFL#10 application, or R5F523E6MGFL#10 equivalent, this device supports IEC60730-compliant self-diagnostic A/D calibration, CAN 2.0B communication at 1 Mbps, and low-power software standby with active LPT - critical for smart grid sensors, load cell interfaces, and precision weight scales requiring stable 24-bit measurement under varying supply and temperature conditions.
Technical Context
The R5F523E6MGFL#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) for functional safety. Its analog subsystem centers on the DSADB module synchronized to PCLKC (≤16 MHz), featuring fourth- and fifth-order sinc digital filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and offset/gain error calibration.
It supports event-driven operation via ELC to trigger ADC conversions, PWM outputs, or D/A updates without CPU intervention - enabling deterministic timing in closed-loop control. The MCU operates across 1.8–5.5 V with three low-power modes, including software standby where only the low-power timer (LPT) and IWDT remain active using the 32.768 kHz sub-clock or dedicated 15-kHz oscillator.

FAQ
What is the maximum sampling rate supported by the 24-bit delta-sigma ADC in R5F523E6MGFL#10?
The R5F523E6MGFL#10 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achieved with modulator clock fMOD = 4 MHz and appropriate sinc filter configuration. At lower rates (e.g., 10 or 54 SPS), the device enables simultaneous 50/60 Hz rejection - a key capability for noise-immune industrial sensing. The R5F523E6MGFL#10 datasheet specifies this value in Table 1.1 and Section 1.1.
Does R5F523E6MGFL#10 include an integrated voltage reference, and what is its accuracy?
Yes, the R5F523E6MGFL#10 includes an on-chip 2.5 V voltage reference (VREF) with ±8 ppm/°C temperature drift over –40°C to +85°C. It delivers ±10 mA output current and serves as the default reference for both the 24-bit DSADB and 12-bit S12ADE converters. This eliminates the need for external references in most precision applications - a feature confirmed in Section 1.1 and Table 1.1 of the R5F523E6MGFL#10 datasheet.
Can R5F523E6MGFL#10 operate in low-power modes while maintaining analog measurement capability?
Yes, the R5F523E6MGFL#10 supports software standby mode where the CPU and most peripherals halt, yet the low-power timer (LPT) and independent watchdog timer (IWDT) remain active. The DSADB can be triggered via ELC events during standby, enabling periodic wake-up and measurement without full CPU activation - critical for battery-operated sensor nodes. This behavior is documented in Section 1.1 and Figure 1.2 of the R5F523E6MGFL#10 datasheet.
What package type and pin count does R5F523E6MGFL#10 use?
The R5F523E6MGFL#10 uses the PLQP0048KB-B package: a 48-pin low-profile quad flat package (LFQFP), 7 mm × 7 mm body size, 0.5 mm pin pitch, with an exposed thermal pad. This matches the "FL" suffix in the part number per Figure 1.1 of the R5F523E6MGFL#10 datasheet. It provides 17 general-purpose I/O pins, 4 high-voltage analog inputs (HVAIN), and dedicated analog power/ground pins for noise-sensitive measurement.
How does R5F523E6MGFL#10 support IEC60730 functional safety compliance?
The R5F523E6MGFL#10 integrates hardware-assisted self-test features required for Class B IEC60730 compliance, including A/D converter disconnect detection, clock frequency accuracy measurement (CAC), RAM test assistance via the data operation circuit (DOC), and independent watchdog timer (IWDT) diagnostics. These capabilities reduce software validation burden and are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R5F523E6MGFL#10 datasheet.
