Renesas R5F5671CDDNE#30

Overview

R5F5671CDDNE#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 secure IoT edge nodes.

For engineers reviewing the R5F5671CDDNE#30 datasheet, R5F5671CDDNE#30 pinout, R5F5671CDDNE#30 application, or R5F5671CDDNE#30 equivalent, this MCU delivers IEC60730-compliant safety features, TSIP-based AES256/SHA256 encryption, real-time clock with battery backup, and 114 GPIOs with 5-V tolerance - critical for deterministic control, secure firmware updates, and low-power always-on sensing.

Technical Context

The R5F5671CDDNE#30 implements the RXv3 CPU core with collective register bank save, memory protection unit (MPU), and JTAG/FINE debug interfaces. It integrates dual-clock domains: ICLK up to 120 MHz for CPU/QSPIX, and PCLKA/B/C/D up to 120/60/60/60 MHz respectively for peripherals including MTU3a timers, S12AD converters, and RIICHS.

Its peripheral architecture supports concurrent high-bandwidth data movement via DMACAb (8 channels), EXDMACa (2 channels), and DTCb (1 channel), while ELC enables hardware-triggered event chaining - eliminating CPU intervention for timer-triggered ADC sampling, PWM synchronization, or RTC alarm-driven wake-up from deep software standby mode.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671CDDNE#30?

The R5F5671CDDNE#30 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 16 general-purpose 32-bit registers, and efficient pipeline design - enabling deterministic real-time response in industrial control applications where R5F5671CDDNE#30 is deployed.

Does the R5F5671CDDNE#30 support secure boot and cryptographic operations?

Yes, the R5F5671CDDNE#30 integrates Trusted Secure IP (TSIP) supporting AES128/192/256, SHA256, ECC, RSA, and a true-random number generator (TRNG). It enables secure boot verification, encrypted firmware storage, and TLS offload - all without CPU intervention. These capabilities are validated in the R5F5671CDDNE#30 datasheet and are essential for meeting IEC60730 Class B and IoT device security requirements.

What package type and pin count does the R5F5671CDDNE#30 use?

The R5F5671CDDNE#30 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size and 0.50-mm pitch. It provides 114 general-purpose I/O pins with 5-V tolerance, open-drain capability, and programmable pull-up resistors - matching the mechanical and thermal requirements of space-constrained industrial control boards where R5F5671CDDNE#30 is integrated.

Can the R5F5671CDDNE#30 execute code directly from external serial flash memory?

Yes, the R5F5671CDDNE#30 includes a Quad-SPI memory interface (QSPIX) that supports execute-in-place (XIP) from external SPI-compatible flash. It handles extended SPI, dual-SPI, and quad-SPI protocols with selectable address widths (8–32 bits), enabling fast, low-pin-count code expansion - a key capability confirmed in the R5F5671CDDNE#30 datasheet for reducing system BOM cost and footprint.

What safety certifications and self-test features does the R5F5671CDDNE#30 support?

The R5F5671CDDNE#30 includes built-in features for IEC60730 Class B compliance: oscillation-stoppage detection, hardware CRC calculation (CRCA), independent watchdog timer (IWDTa) with windowing, ADC self-diagnostic, and register write protection. These are documented in the R5F5671CDDNE#30 datasheet and reduce validation effort for safety-critical applications such as smart meters and industrial HMIs where R5F5671CDDNE#30 serves as the primary controller.
