Renesas R5F5671CHDFM#30

Overview

R5F5671CHDFM#30 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring double-precision IEEE-754 FPU, 2 MB on-chip code flash with dual-bank support, 384 KB SRAM, and integrated CAN, USB 2.0 FS, SD host interface, QSPIX, and capacitive touch sensing - deployed in industrial HMI, smart metering, and connected appliance control systems.

For engineers reviewing the R5F5671CHDFM#30 datasheet, R5F5671CHDFM#30 pinout, R5F5671CHDFM#30 application, or R5F5671CHDFM#30 equivalent, key selection criteria include its 120-MHz real-time performance, IEC60730-compliant safety features (TSIP, MPU, self-diagnostic A/D), 114 GPIOs with 5-V tolerance, and low-power deep software standby mode with RTC and backup RAM retention.

Technical Context

The R5F5671CHDFM#30 implements the RXv3 CPU core with 113 instructions, including DSP and floating-point extensions, and supports little-endian or big-endian data arrangement. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT clock (120 kHz), enabling precise timing control across multiple domains (ICLK up to 120 MHz, PCLKA/B up to 120/60 MHz).

Peripheral subsystems are tightly coupled via the Event Link Controller (ELC), allowing hardware-triggered timer-A/D/communication events without CPU intervention. The device uses a hierarchical power architecture with four low-power modes, battery-backed RTC and 4 KB standby RAM, and voltage monitoring with three LVD circuits for robust operation in industrial environments.
