Product details
Overview
R5F523E6BGFL#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 ±10-V input capability, 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 –40°C to +105°C temperature range.
For engineers reviewing the R5F523E6BGFL#10 datasheet, R5F523E6BGFL#10 pinout, R5F523E6BGFL#10 application, or R5F523E6BGFL#10 equivalent, this device supports IEC60730-compliant self-diagnostic functions, CAN 2.0B communication at 1 Mbps, and ELC-triggered background A/D conversion - critical for smart transmitters, load cells, and precision weight scales requiring metrology-grade accuracy and functional safety support.
Technical Context
The R5F523E6BGFL#10 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, delivering 64 DMIPS at 32 MHz. Its analog subsystem centers on the DSADB unit synchronized to PCLKC (≤16 MHz), featuring fourth- and fifth-order sinc digital filters, simultaneous 50/60 Hz rejection, and offset/gain error calibration.
Digital control is enabled via MTU2a (6-channel 16-bit timer with complementary PWM), ELC-driven event chaining without CPU wake-up, and dual A/D converters: the 24-bit DSADB (3.8 SPS–125 kSPS) and 12-bit S12ADE (1.4 µs conversion time). The MCU supports three low-power modes and includes an MPU, FPU (IEEE 754 single-precision), and hardware CRC generator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6KGFM#10 | Same RX23E-B G-version MCU but in 64-pin LFQFP (PLQP0064KB-C); adds RTC and LCD driver; no HVAIN pins. | Targeted at panel-mounted HMI devices needing display output and calendar functions - not suitable for ±10-V sensor interfaces. | Select only if RTC or LCD functionality is required and HVAIN is unnecessary; pinout and PCB layout differ significantly. |
| ADS131M08IPBSR | Dedicated 24-bit delta-sigma ADC (8-channel, SPI interface) with PGA and ±10-V inputs - no MCU core, flash, or peripherals. | Used with external host MCU for modular sensor designs where separation of analog and control domains is preferred. | Choose when system architecture mandates standalone ADC + separate processor; requires additional firmware development for diagnostics and communication stack. |
Compared with R5F523E6KGFM#10, the R5F523E6BGFL#10 provides HVAIN pins and smaller 48-pin footprint at the cost of RTC/LCD; versus ADS131M08IPBSR, it delivers integrated processing, safety features, and CAN connectivity - reducing BOM count and enabling autonomous edge intelligence.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6BGFL#10?
The R5F523E6BGFL#10 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB) when configured with fMOD = 4 MHz. This rate applies to single-channel operation with lower-order sinc filtering; higher-order filters reduce effective throughput to enable enhanced noise rejection, such as 10 SPS for simultaneous 50/60 Hz rejection.
Does R5F523E6BGFL#10 include a real-time clock (RTC)?
No, the R5F523E6BGFL#10 does not include a real-time clock. Per Table 1.2 of the datasheet, RTC functionality is omitted in the 48-pin LFQFP package variant (PLQP0048KB-B). RTC is available only in 100-pin and 80-pin packages of the RX23E-B Group, such as R5F523E6LGFP#10 or R5F523E6JGFN#10.
What analog input voltage range does R5F523E6BGFL#10 support?
The R5F523E6BGFL#10 supports ±10-V differential input on its HVAIN0–HVAIN3 pins, enabling direct connection to high-output sensors like load cells and isolation amplifiers. Non-HVAIN analog inputs (e.g., standard AIN pins) operate within the AVCC0/AVSS0 range, typically 0–5 V when AVCC0 = 5 V.
Can R5F523E6BGFL#10 drive a CAN bus directly without external transceivers?
No, the R5F523E6BGFL#10 contains only the CAN protocol controller (RSCAN module) and requires an external CAN physical-layer transceiver (e.g., TJA1042, SN65HVD230) to interface with the differential CAN_H/CAN_L bus. The CAN_TX and CAN_RX pins are CMOS-level signals compliant with ISO 11898-1 logical layer requirements.
What is the operating temperature grade of R5F523E6BGFL#10?
The R5F523E6BGFL#10 is a G-version device rated for an operating ambient temperature range of –40°C to +105°C. This is confirmed by the "G" in the part number per Figure 1.1 of the datasheet and qualifies the MCU for deployment in demanding industrial environments such as motor drives, power supplies, and outdoor utility equipment.
