Renesas R5F523E6JGFN#30

Overview

R5F523E6JGFN#30 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 2.5-V low-drift voltage reference (8 ppm/°C). Operating at up to 32 MHz, it delivers 64 DMIPS and includes CAN, SCI, I²C, and RSPI interfaces.

For engineers reviewing the R5F523E6JGFN#30 datasheet, R5F523E6JGFN#30 pinout, R5F523E6JGFN#30 application, or R5F523E6JGFN#30 equivalent, this MCU is selected for embedded systems requiring simultaneous high-resolution analog acquisition, real-time control, and deterministic communication - especially in load cell, pressure transducer, and industrial process monitoring designs where offset drift (4 nV/°C) and gain drift (1 ppm/°C) directly impact calibration stability.

Technical Context

The R5F523E6JGFN#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE 754-compliant 32-bit FPU - enabling real-time floating-point computation for sensor linearization and digital filtering. Its analog subsystem centers on the DSADB module, synchronized to PCLKC (≤16 MHz), with configurable sinc filters and ELC-triggered conversion to minimize CPU intervention.

It supports three low-power modes (sleep, deep sleep, software standby), with LPT operating during standby using sub-clock or IWDT oscillator. The integrated RSCAN CAN controller complies with ISO 11898-1 at up to 1 Mbps, while the 80-pin LFQFP package enables 43 GPIOs, including 6 with 5-V tolerance and dedicated HVAIN pins for ±5-V analog inputs.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6JGFN#30?

The R5F523E6JGFN#30 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB) when configured with fMOD = 4 MHz and appropriate sinc filter settings. This rate applies to single-channel operation; multi-channel scanning reduces effective throughput due to settling time and filter latency. The device also supports lower rates (e.g., 10 SPS or 54 SPS) with enhanced 50/60 Hz noise rejection.

Does R5F523E6JGFN#30 include an integrated LCD controller, and what configurations does it support?

Yes, the R5F523E6JGFN#30 includes an integrated LCD controller/driver (LCDC) supporting either 40-segment × 4-common or 36-segment × 8-common configurations. It offers internal voltage boosting, capacitor split, and external resistor division methods for contrast control. The LCDC operates independently of the CPU and can drive static or multiplexed segments without external components - confirmed in Table 1.2 for 80-pin LFQFP packages like R5F523E6JGFN#30.

What are the supported excitation current values and matching specifications for R5F523E6JGFN#30?

The R5F523E6JGFN#30 provides two independent excitation current sources (IEXC0/IEXC1) with programmable output values of 50 µA, 100 µA, 250 µA, 500 µA, 750 µA, or 1000 µA. Current matching between channels is ±0.2%, and drift matching is 5 ppm/°C - enabling high-accuracy ratiometric measurements in 3- and 4-wire RTD or strain gauge applications without external calibration.

Can R5F523E6JGFN#30 operate with a single power supply, and what are the voltage requirements?

Yes, the R5F523E6JGFN#30 operates from a single 1.8-V to 5.5-V supply (VCC) for digital logic. However, the analog front end requires AVCC0 = 4.5–5.5 V for full 12-bit ADC and DSADB performance; operation down to 1.8 V is permitted only for S12AD if DSADB is inactive. This dual-supply flexibility simplifies design while preserving analog accuracy where needed.

Is the R5F523E6JGFN#30 pin-compatible with other members of the RX23E-B Group, such as R5F523E5JGFN?

Yes, the R5F523E6JGFN#30 is pin-compatible with R5F523E5JGFN and all other 80-pin LFQFP variants (FN suffix) in the RX23E-B Group. They share identical PLQP0080KB-B packaging, pin functions, and peripheral mappings - allowing hardware reuse across memory and temperature grade variants. Firmware porting requires only flash/RAM size adjustments and optional G/D-grade initialization code changes.
