Renesas R5F523E6JDFN#10

Overview

R5F523E6JDFN#10 from Renesas is a 32-bit RXv2 microcontroller designed for high-precision industrial sensing and measurement systems. It integrates a 24-bit delta-sigma ADC with 125 kSPS max sampling rate, ±5-V analog input range, LCD controller, 256 KB flash, 32 KB SRAM, and CAN interface - all operating at up to 32 MHz in a compact 80-pin LFQFP package.

For engineers reviewing the R5F523E6JDFN#10 datasheet, R5F523E6JDFN#10 pinout, R5F523E6JDFN#10 application, or R5F523E6JDFN#10 equivalent, this MCU delivers calibrated high-resolution analog acquisition, real-time control via MTU2a timers, deterministic event-driven operation via ELC, and IEC60730-compliant safety features for embedded metering and process monitoring.

Technical Context

The R5F523E6JDFN#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) for secure execution. Its analog subsystem centers on a single 24-bit delta-sigma A/D converter (DSADB) supporting eight differential inputs, programmable gain instrumentation amplifier (PGA), and four sinc-based digital filters - all synchronized to PCLKC up to 16 MHz.

Real-time coordination is enabled by the Event Link Controller (ELC), which allows direct module-to-module triggering without CPU intervention, including DSAD conversion start, MTU2a waveform generation, and DTC transfers. The device supports three low-power modes and includes an independent watchdog timer (IWDT) driven by a dedicated 15-kHz on-chip oscillator.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6JDFN#10?

The R5F523E6JDFN#10 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma A/D converter (DSADB). This rate is achievable at lower resolution settings and with appropriate modulator clock configuration (fMOD = 4 MHz). At 3.8 SPS, the device achieves 24-bit effective resolution with gain = 1. The sampling rate is programmable across 3.8 SPS to 125 kSPS depending on filter selection and oversampling ratio.

Does R5F523E6JDFN#10 include an LCD controller, and what display configurations does it support?

Yes, R5F523E6JDFN#10 includes an integrated LCD controller/driver (LCDC) as indicated by the "J" suffix in its part number. It supports 40 segment × 4 common (40 × 4) configurations using internal voltage boosting. The LCDC operates independently of the CPU and supports static, 1/2, and 1/3 bias methods - enabling direct drive of character or segmented displays in panel meters and HMI applications without external drivers.

What analog input voltage range is supported by R5F523E6JDFN#10, and does it support ±10-V inputs?

R5F523E6JDFN#10 supports a maximum analog input range of ±5 V, as confirmed by its "J" variant designation in Table 1.3 and Figure 1.1. It does not support ±10-V inputs - that capability is reserved for "K" and "L" variants (e.g., R5F523E6KDFM#10). The J variant uses standard AIN pins (not HVAIN), and its DSAD input structure is optimized for 5-V full-scale operation with rail-to-rail PGA and internal bias voltage generation.

How many excitation current sources does R5F523E6JDFN#10 provide, and what are their key specifications?

R5F523E6JDFN#10 provides two independent excitation current sources (IEXC0 and IEXC1), each programmable from 50 µA to 1000 µA in six discrete steps. Key specs include ±0.2% current matching between channels and 5 ppm/°C drift matching - critical for precision RTD and strain gauge measurements. These sources are internally connected to the analog multiplexer and support disconnect detection assist for open-wire fault diagnosis.

Is R5F523E6JDFN#10 qualified for IEC60730 compliance, and which safety features are hardware-supported?

Yes, R5F523E6JDFN#10 includes hardware-assisted functions specifically designed to support IEC60730 Class B compliance. These include self-diagnostic routines 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 reduce software validation burden and enable certified functional safety implementations in industrial control equipment.
