Product details
Overview
R5F523E6BDFM#10 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensor signal conditioning and measurement, featuring a 24-bit delta-sigma ADC with 125 kSPS max sampling rate, ±5-V analog input range, 256-KB flash, 32-KB SRAM, integrated programmable gain instrumentation amplifier (PGA), excitation current sources, and CAN interface. It operates at up to 32 MHz across –40°C to +85°C and targets load cell, pressure transducer, and RTD-based measurement systems.
For engineers reviewing the R5F523E6BDFM#10 datasheet, R5F523E6BDFM#10 pinout, R5F523E6BDFM#10 application, or R5F523E6BDFM#10 equivalent, this MCU delivers calibrated high-resolution analog front-end performance with on-chip voltage reference (2.5 V, 8 ppm/°C), low-drift PGA (11 nVRMS, gain = 128), and IEC60730-compliant self-test functions - critical for Class B safety certification in industrial weighing and process control.
Technical Context
The R5F523E6BDFM#10 integrates a dedicated analog subsystem centered on the DSADB 24-bit delta-sigma ADC, synchronized to PCLKC (up to 16 MHz), with four selectable sinc filter configurations and simultaneous 50/60 Hz rejection at 10/54 SPS. Its AFE includes rail-to-rail PGA (gain 1–128), two 50–1000 µA excitation current sources (±0.2% matching), ±10-V HVAIN pins (though this variant supports only ±5 V), and bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2).
It employs the RXv2 CPU core with IEEE 754-compliant FPU, memory protection unit (MPU), and event link controller (ELC) enabling interrupt-free peripheral coordination - e.g., triggering ADC conversions from MTU2a timers while CPU remains in deep sleep. Clock domains are strictly partitioned: ICLK (CPU/system, ≤32 MHz), PCLKA (MTU2a), PCLKC (DSADB), and PCLKD (S12AD).

Applications
| Industrial Weighing Terminal | Pressure Transducer Signal Conditioner |
|---|---|
|
Use Scenario: Digital load cell interface in platform scales and hopper weighers requiring <10 µV resolution and temperature compensation. IC Role / Device Role / Timing Role: Primary signal processor: digitizes mV-level bridge output via DSADB, applies PGA gain, performs real-time linearization and temperature correction using FPU. Use Value: Achieves <0.005% FS accuracy over –40°C to +85°C using on-chip VREF (8 ppm/°C), excitation current matching (±0.2%), and built-in offset/gain calibration. |
Use Scenario: Analog front-end for piezoresistive pressure sensors in HVAC and process automation, where long-term stability and EMI immunity are critical. IC Role / Device Role / Timing Role: Sensor interface MCU: supplies matched excitation currents (IEXC0/IEXC1), rejects 50/60 Hz line noise digitally, and communicates calibrated pressure values via CAN. Use Value: Eliminates external precision op-amps and reference ICs; sinc filter + PGA achieves 11 nVRMS noise floor and simultaneous mains-frequency rejection at 10 SPS. |
| RTD-Based Temperature Controller | Programmable Logic Controller (PLC) Analog Input Module |
|
Use Scenario: 3-wire/4-wire Pt100/Pt1000 interface in DIN-rail mounted temperature controllers for industrial ovens and chillers. IC Role / Device Role / Timing Role: Precision analog acquisition node: drives RTD with programmable IEXC, measures voltage drop across precision resistor, compensates for lead resistance via software. Use Value: On-chip excitation current sources (50–1000 µA, 5 ppm/°C drift matching) and 24-bit ADC enable <0.1°C resolution without external current sources or Kelvin sensing circuitry. |
Use Scenario: Modular analog input card for compact PLCs handling multiple 4–20 mA or 0–10 V field signals in factory automation. IC Role / Device Role / Timing Role: Multi-channel measurement engine: time-multiplexes DSADB across 8 differential inputs, runs CRC integrity checks on all ADC data, reports faults via CAN bus. Use Value: Integrated 12-bit S12AD (1.4 µs conversion) handles fast control loops, while DSADB provides high-resolution monitoring - both share same AFE resources with no external components. |
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 |
|---|---|---|---|
| R5F523E6KDFM#10 | Same 64-pin LFQFP package, identical peripherals, but supports ±10-V analog input range (HVAIN pins enabled) | Required for direct ±10-V sensor interfaces (e.g., high-output load cells); R5F523E6BDFM#10 limited to ±5 V | Select KDFM if full ±10-V input range is needed; otherwise BDFM reduces design complexity and cost. |
| R5F523E5BDFM#10 | Same package and pinout, but 128-KB flash / 16-KB RAM / 256-KB ROM configuration; otherwise identical analog/peripheral specs | Suitable for cost-sensitive designs with smaller firmware footprint and lower memory requirements | Choose R5F523E5BDFM#10 when application code size fits in 128 KB and 16 KB RAM suffices - retains full AFE capability. |
Compared with R5F523E6KDFM#10, R5F523E6BDFM#10 trades ±10-V input headroom for simplified analog layout and reduced external protection needs; versus R5F523E5BDFM#10, it doubles flash and RAM for complex filtering, communication stacks, or dual-firmware OTA updates - all while sharing identical AFE accuracy and timing behavior.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6BDFM#10?
The R5F523E6BDFM#10 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achievable at lower resolution settings and with appropriate modulator clock configuration (fMOD = 4 MHz). At full 24-bit effective resolution, typical usable rates are 3.8 SPS (gain = 1) to 31.25 kSPS (gain = 1, reduced oversampling).
Does R5F523E6BDFM#10 include an LCD controller/driver?
No, R5F523E6BDFM#10 does not include an LCD controller/driver. The "B" suffix in the part number explicitly denotes exclusion of the LCDC module. This distinguishes it from "J", "L", "N", and "G" variants that integrate LCD driving capability. The R5F523E6BDFM#10 is optimized for pure analog measurement applications without display requirements.
What analog input voltage range is supported by R5F523E6BDFM#10?
R5F523E6BDFM#10 supports a ±5-V analog input range on its HVAIN pins. Although the hardware pins are rated for ±10 V, the "B" variant is factory-configured and characterized for ±5-V full-scale operation. For ±10-V input capability, the R5F523E6KDFM#10 (same package) must be selected.
How many excitation current sources does R5F523E6BDFM#10 provide, and what are their specifications?
R5F523E6BDFM#10 provides two independent excitation current sources (IEXC0 and IEXC1), each programmable from 50 µA to 1000 µA in six discrete steps. They feature ±0.2% current matching and 5 ppm/°C drift matching - critical for 3-wire/4-wire RTD measurements where ratio-metric accuracy depends on source consistency.
Is R5F523E6BDFM#10 qualified for IEC60730 Class B compliance?
Yes, R5F523E6BDFM#10 includes hardware-assisted self-test features required for IEC60730 Class B: ADC diagnostic assist (offset/gain error detection), clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) test mode, RAM test support via DOC, and analog input disconnect detection - all documented in the R01DS0402EJ0100 datasheet.
