R5F5671CHGNE#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 and smart metering systems requiring real-time control and secure firmware updates.

For engineers reviewing the R5F5671CHGNE#30 datasheet, R5F5671CHGNE#30 pinout, R5F5671CHGNE#30 application, or R5F5671CHGNE#30 equivalent, key selection considerations include its G-grade (–40°C to +105°C) operation, PLQP0144KA-B 144-pin LQFP package, TSIP-based AES256/SHA256 encryption, and 12-bit dual A/D converter with self-diagnostic capability.

Technical Context

The R5F5671CHGNE#30 implements the RXv3 CPU core with collective register bank save, memory protection unit (MPU), and JTAG/FINE debug interfaces. It integrates dual-bank flash enabling background programming and safe firmware swapping during runtime, alongside a dedicated low-power domain supporting RTC and backup registers via VBATT.

Its peripheral architecture includes EXDMACa (2-channel extended DMA), DTCb (1-channel data transfer controller), and ELC (event link controller) for CPU-free inter-module triggering - critical for deterministic timing in motor control and IEC60730-compliant safety applications.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671CHGNE#30?

The R5F5671CHGNE#30 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark. This performance stems from its RXv3 CPU core with dual-issue pipeline, on-chip 32-bit multiplier/divider, and optimized instruction set - validated per EEMBC methodology. The R5F5671CHGNE#30 sustains this score under full load with all peripherals active and cache enabled.

Does the R5F5671CHGNE#30 support secure boot and cryptographic operations?

Yes, the R5F5671CHGNE#30 integrates Trusted Secure IP (TSIP) supporting AES128/192/256, SHA256, RSA, ECC, and a true random number generator (TRNG). It enables secure boot via encrypted firmware validation and key protection against illicit copying - meeting IEC62443-3-3 SL2 requirements. The R5F5671CHGNE#30 uses these features to authenticate OTA updates and protect sensitive configuration data.

What package type and pin count does the R5F5671CHGNE#30 use?

The R5F5671CHGNE#30 uses the PLQP0144KA-B package: a 144-pin LQFP measuring 20 × 20 mm with 0.50-mm pitch. It provides 113 general-purpose I/O pins, 20 of which are 5-V tolerant, and dedicated power/ground pins for analog and digital domains. This package is fully supported in Renesas' e2 studio and QE tools for R5F5671CHGNE#30 development.

Can the R5F5671CHGNE#30 execute code directly from external serial flash memory?

Yes, the R5F5671CHGNE#30 includes a Quad-SPI memory interface (QSPIX) that supports direct execution (XIP) from external serial flash using extended SPI, dual-SPI, and quad-SPI protocols. Address width is configurable (8/16/24/32 bits), and the interface operates synchronously with ICLK up to 120 MHz - enabling R5F5671CHGNE#30 to eliminate external parallel memory and reduce system cost and footprint.

What low-power modes are available on the R5F5671CHGNE#30, and how does backup power work?

The R5F5671CHGNE#30 supports four low-power modes: Sleep, All-Module Clock Stop, Software Standby, and Deep Software Standby - with the latter retaining 4 KB of standby RAM and RTC operation. Backup power is supplied via the VBATT pin, sustaining the sub-clock oscillator, RTC, and backup registers during main power loss. This ensures continuous timekeeping and tamper-event logging in R5F5671CHGNE#30-based energy meters and security controllers.
