Product details
Overview
R5F523E5SGFL#10 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 up to 32 MHz with 128 KB flash, 16 KB SRAM, and 8 KB data flash, targeting thermocouple and RTD measurement systems in industrial process control.
For engineers reviewing the R5F523E5SGFL#10 datasheet, R5F523E5SGFL#10 pinout, R5F523E5SGFL#10 application, or R5F523E5SGFL#10 equivalent, this MCU delivers calibrated 23-bit effective resolution at 7.6 SPS, simultaneous 50/60 Hz rejection, on-chip self-diagnostic support for IEC 60730 Class B compliance, and event-driven peripheral coordination via ELC-enabling deterministic low-power sensor acquisition without CPU intervention.
Technical Context
The R5F523E5SGFL#10 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, programmable PGA per channel, and synchronized start capability. Its analog front end includes dedicated excitation current sources (IEXC0–IEXC3), bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), and low-side switch (10 Ω max) for 4-wire RTD configurations.
Digital subsystem features include a 32-bit RXv2 CPU core (64 DMIPS @ 32 MHz), FPU compliant with IEEE 754 single-precision, memory protection unit (MPU), and event link controller (ELC) enabling direct module-to-module triggering-e.g., MTU2a timer events initiating DSAD conversion or CAN message transmission-while the CPU remains in deep sleep mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision sensor interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5ADFL#30 | Same RX23E-A core, identical pinout, but D-grade (–40°C to +85°C) and dual DSAD units enabled | Targeted at commercial/industrial environments without extended temperature requirements | Select when ambient operating temperature does not exceed +85°C and full DSAD functionality is required |
| ADS124S08IRHBT | Standalone 24-bit delta-sigma ADC with PGA, no MCU, no CAN, no flash/SRAM | Requires external host MCU for control, communication, and firmware logic | Choose when system architecture separates analog acquisition and processing functions, or when CAN interface is unnecessary |
Compared with R5F523E5SGFL#10, R5F523E5ADFL#30 offers identical analog performance but lacks extended temperature qualification, while ADS124S08IRHBT provides higher standalone ADC SNR but requires external processing resources and adds board-level complexity for CAN or IEC 60730 compliance.

FAQ
What is the maximum effective resolution achievable with the R5F523E5SGFL#10's delta-sigma ADCs?
The R5F523E5SGFL#10 achieves up to 23-bit effective resolution at 7.6 SPS with gain = 1 and output data rate = 7.6 SPS, as specified in the datasheet (R01DS0330EJ0130 Rev.1.30, Page 1). This performance is enabled by its fourth-order sinc filter, programmable oversampling ratio (32–65536), and low-drift PGA. The R5F523E5SGFL#10 maintains this resolution across its full –40°C to +105°C operating range due to integrated temperature compensation and on-chip calibration support.
Does the R5F523E5SGFL#10 support simultaneous sampling across both delta-sigma ADC units?
Yes, the R5F523E5SGFL#10 supports inter-unit A/D conversion synchronized start, allowing both DSAD0 and DSAD1 to begin conversion at the exact same time. This is triggered either by software command or via the Event Link Controller (ELC) using a shared event source such as a timer overflow. The feature is documented in the "Analog Functions" section of the datasheet (R01DS0330EJ0130 Rev.1.30, Page 4) and is essential for phase-coherent multi-sensor acquisition in applications like 3-phase energy metering or multi-point temperature profiling.
Can the R5F523E5SGFL#10 operate in low-power modes while maintaining analog measurement capability?
Yes, the R5F523E5SGFL#10 supports three low-power consumption modes-including software standby-with the Low Power Timer (LPT) continuing to operate using the IWDT-dedicated oscillator. During software standby, DSAD conversion can be initiated via LPT interrupt or ELC-triggered events, enabling periodic sensor polling at microamp-level current draw. This capability is confirmed in the "Low power consumption functions" section (R01DS0330EJ0130 Rev.1.30, Page 3) and is critical for battery-powered or energy-harvesting industrial sensors.
What level of IEC 60730 compliance does the R5F523E5SGFL#10 support out-of-the-box?
The R5F523E5SGFL#10 includes hardware-assisted functions for IEC 60730 Class B compliance, including self-diagnostic support for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the Data Operation Circuit (DOC), and analog input disconnect detection. These features are explicitly listed under "Useful functions for IEC60730 compliance" in the datasheet (R01DS0330EJ0130 Rev.1.30, Page 1). Full certification requires system-level implementation, but the R5F523E5SGFL#10 provides the foundational hardware building blocks.
Is the R5F523E5SGFL#10 pin-compatible with other members of the RX23E-A Group?
Yes, the R5F523E5SGFL#10 uses the 48-pin LFQFP package (PLQP0048KB-B) and shares identical pin assignments with all other 48-pin RX23E-A variants, including R5F523E6AGFL#30 and R5F523E5ADFL#30. Pin compatibility is verified in Table 1.2 ("Comparison of Functions for Different Packages") and Figure 1.4 ("Pin Assignments of the 48-Pin LFQFP") of the datasheet (R01DS0330EJ0130 Rev.1.30, Pages 6 and 14). This enables drop-in replacement within the same package family when adjusting flash size, temperature grade, or DSAD configuration.
