Product details
Overview
R5F523E6BDNF#00 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing applications. It integrates a 24-bit delta-sigma ADC with 125 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 on a single 1.8–5.5 V supply.
For engineers reviewing the R5F523E6BDNF#00 datasheet, R5F523E6BDNF#00 pinout, R5F523E6BDNF#00 application, or R5F523E6BDNF#00 equivalent, this MCU delivers calibrated high-resolution sensor signal acquisition with integrated analog front-end (AFE), real-time control via MTU2a PWM and CAN 2.0B interface, and IEC60730-compliant safety features - critical for load cell, pressure transducer, and weigh scale designs requiring <10 ppm/°C gain drift and 4 nV/°C offset drift.
Technical Context
The R5F523E6BDNF#00 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 5-stage pipeline, and memory protection unit (MPU) - enabling deterministic real-time execution of sensor calibration algorithms and digital filtering. Its DSADB module synchronizes modulator clock (4 MHz typ.) with PCLKC (≤16 MHz) and supports four sinc filter configurations for simultaneous 50/60 Hz rejection at 10/54 SPS.
Analog subsystem integration includes dual excitation current sources with ±0.2% matching and 5 ppm/°C drift matching, bias voltage generator (AVCC0 + AVSS0)/2, and ±5-V HVAIN pins with low-side switch (10 Ω max). The device lacks LCD controller support per package variant B and operates across –40°C to +85°C (D version).

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 |
|---|---|---|---|
| R5F523E5BDNF#00 | 128 KB flash / 16 KB SRAM; identical analog specs, same 40-pin HWQFN package | Suitable for cost-sensitive designs where firmware footprint <128 KB | Select when application code size fits within 128 KB and full 256 KB headroom is unnecessary |
| ADS125H02IRHBT | Dedicated 24-bit delta-sigma ADC with integrated PGA and excitation sources; no MCU core or flash | Requires external host processor for control, filtering, and communication | Choose when system already has a capable host MCU and only needs best-in-class analog front-end performance |
Compared with R5F523E5BDNF#00, the R5F523E6BDNF#00 provides double flash/SRAM for complex calibration algorithms and larger communication stacks; versus ADS125H02IRHBT, it eliminates external processor dependency but trades off ultimate ADC SNR for integrated control capability.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6BDNF#00?
The R5F523E6BDNF#00 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achievable with reduced effective resolution and specific sinc filter configuration; at 3.8 SPS, it achieves 24-bit effective resolution with gain = 1. The device also supports lower rates including 10 SPS and 54 SPS for simultaneous 50 Hz/60 Hz rejection.
Does R5F523E6BDNF#00 include an LCD controller?
No, R5F523E6BDNF#00 does not include an LCD controller. Per Renesas' part numbering scheme, the "B" suffix in R5F523E6BDNF#00 explicitly denotes absence of LCD driver functionality. This distinguishes it from variants like R5F523E6JDFN (suffix "J") which include LCD support. The R5F523E6BDNF#00 is optimized for compact sensor interface applications where display capability is handled externally.
What analog input voltage range is supported by R5F523E6BDNF#00?
R5F523E6BDNF#00 supports a ±5-V analog input range on its HVAIN pins, as confirmed by the "B" variant designation in Table 1.3 and Figure 1.1 of the datasheet. It does not support the ±10-V range offered by "K" and "L" variants. This ±5-V range is sufficient for most bridge-based load cells and industrial pressure sensors operating with standard excitation voltages.
What is the operating temperature grade of R5F523E6BDNF#00?
R5F523E6BDNF#00 is rated for –40°C to +85°C operation (D grade), as indicated by the "D" in its part number. This industrial temperature range meets requirements for factory automation, building controls, and outdoor instrumentation where ambient conditions exceed commercial-grade limits but do not require extended high-temperature operation.
How many excitation current sources does R5F523E6BDNF#00 integrate?
R5F523E6BDNF#00 integrates two independent excitation current sources (IEXC0 and IEXC1), each programmable from 50 µA to 1000 µA in discrete steps. These sources feature ±0.2% matching and 5 ppm/°C drift matching - enabling precise 4-wire RTD measurements and balanced bridge excitation without external current DACs.
