Product details
Overview
R5F5671EHDFB#30 from Renesas Electronics 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 secure IoT edge nodes.
For engineers reviewing the R5F5671EHDFB#30 datasheet, R5F5671EHDFB#30 pinout, R5F5671EHDFB#30 application, or R5F5671EHDFB#30 equivalent, key selection criteria include its 120-MHz real-time performance (707 CoreMark), TSIP-based AES256/SHA256 encryption, IEC60730-compliant safety features, and 114 GPIOs with 5-V tolerance - all in a 144-pin LFQFP package.
Technical Context
The R5F5671EHDFB#30 implements the RXv3 CPU core with collective register bank save, memory protection unit (MPU), and JTAG/FINE debug interfaces. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), and dedicated IWDT oscillator (120 kHz), enabling independent domain clocking: ICLK up to 120 MHz for CPU/QSPIX, PCLKA up to 120 MHz for MTU/RSPI/RIICHS, and PCLKB up to 60 MHz for most peripherals including S12AD units.
It supports four low-power modes (sleep, all-module clock stop, software standby, deep software standby) with battery-backed RTC and 4 KB standby RAM. The dual-bank flash enables safe firmware updates via background programming (BGO), while the TSIP module provides hardware-accelerated AES128/192/256, RSA, ECC, TRNG, and key protection - critical for secure boot and OTA updates.
