Product details
Overview
R5F523E6SGFL#10 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor measurement, 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), and integrated excitation current sources (50–1000 µA). 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 R5F523E6SGFL#10 datasheet, R5F523E6SGFL#10 pinout, R5F523E6SGFL#10 application, or R5F523E6SGFL#10 equivalent, key selection criteria include its dual 24-bit DSAD units with simultaneous 50/60 Hz rejection, on-chip PGA offset drift (10 nV/°C), CAN 2.0B interface (1 Mbps), and IEC60730-compliant self-diagnostic functions for A/D, clock accuracy, and RAM test assistance.
Technical Context
The R5F523E6SGFL#10 implements a Harvard-architecture RXv2 CPU with 5-stage pipeline, 64 DMIPS @ 32 MHz, and IEEE 754-compliant single-precision FPU. Its analog subsystem integrates two independent 24-bit delta-sigma ADCs with fourth-order sinc filters, programmable data rates (1.9–15625 SPS), and synchronized start capability.
Digital peripherals include one CAN channel (ISO11898-1), three SCIg interfaces (asynchronous/clock-sync/Smart Card), one RIIC (400 kbps), one RSPI (16 Mbps), six MTU2a timer channels, and ELC-driven event-triggered operation-enabling low-power sensor acquisition without CPU wake-up.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUCM360BCPZ-RL7 | ARM Cortex-M3 core, single 24-bit ΣΔ ADC, no integrated CAN, 128 KB flash | Lacks dual DSAD synchronization, CAN interface, and IEC60730 diagnostic assist features | Prefer when ARM toolchain compatibility is required and CAN is handled externally |
| ADS131M04IPBSR | Standalone 4-channel 24-bit ΣΔ ADC with PGA, no MCU core or flash memory | Requires external host MCU for processing, calibration, and communication - increases BOM count and layout complexity | Choose when maximum analog performance is prioritized over integration and firmware flexibility |

FAQ
What is the maximum effective resolution of the R5F523E6SGFL#10's delta-sigma ADCs?
The R5F523E6SGFL#10 achieves up to 23-bit effective resolution with its 24-bit delta-sigma ADCs when operating in normal mode at 7.6 SPS with gain = 1. This is confirmed in the datasheet (R01DS0330EJ0130, p.1) and enables Class 0.1 weighing accuracy. Resolution decreases with higher output data rates due to oversampling trade-offs.
Does the R5F523E6SGFL#10 support simultaneous sampling across both DSAD units?
Yes, the R5F523E6SGFL#10 supports inter-unit A/D conversion synchronized start, allowing precise time-aligned sampling of two independent sensor channels. This feature is explicitly documented in the datasheet (R01DS0330EJ0130, p.1) and is critical for phase-sensitive measurements like 3-phase power monitoring or dual-bridge load cells.
What is the operating temperature grade of the R5F523E6SGFL#10?
The R5F523E6SGFL#10 is rated for –40°C to +105°C ambient operation (G-grade), as indicated by the 'G' in the part number per Figure 1.1 (R01DS0330EJ0130, p.8). This makes it suitable for under-hood automotive, industrial motor drives, and enclosed process control equipment.
How many excitation current sources does the R5F523E6SGFL#10 integrate, and what are their key specs?
The R5F523E6SGFL#10 integrates four excitation current sources (IEXC0–IEXC3) with programmable output from 50 µA to 1000 µA, current matching of ±0.2%, and drift matching of 5 ppm/°C. These are detailed in the Analog Front End section (R01DS0330EJ0130, p.5) and enable precise 2-/3-/4-wire RTD and strain gauge measurements.
Is the R5F523E6SGFL#10 pin-compatible with other RX23E-A group members in the same package?
Yes, all 48-pin LFQFP variants in the RX23E-A Group-including R5F523E6SGFL#10, R5F523E6ADFL#30, and R5F523E6SDFL#30-share identical pin assignments per Figure 1.4 (R01DS0330EJ0130, p.14). Function availability (e.g., DSAD units, SCI channels) varies by part number but physical pinout remains consistent.
