Renesas R5F5671EDDFM#10

Overview

R5F5671EDDFM#10 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, secure firmware updates, and low-power operation.

For engineers reviewing the R5F5671EDDFM#10 datasheet, R5F5671EDDFM#10 pinout, R5F5671EDDFM#10 application, or R5F5671EDDFM#10 equivalent, key selection criteria include its 145-pin TFLGA (0.65-mm pitch) package, IEC60730-compliant safety features (TSIP, CRC, IWDTa, self-diagnostic A/D), 12-bit dual A/D converter with disconnection detection, and RTC with battery-backed time capture across three pins.

Technical Context

The R5F5671EDDFM#10 implements the RXv3 CPU core with 113 instructions, 16 general-purpose 32-bit registers, and double-precision FPU supporting 21 dedicated instructions. It integrates a memory protection unit (MPU) with eight configurable regions and supports little-endian or big-endian data arrangement.

Its clock system combines external crystal (8–24 MHz), sub-clock (32.768 kHz), and internal oscillators (LOCO at 240 kHz, HOCO at 16/18/20 MHz), with independent PLL for 120-MHz ICLK generation. Peripheral clocks are decoupled: PCLKA (up to 120 MHz) drives MTU3a and RSPI, while PCLKB (up to 60 MHz) serves TMRb, CMT, and most timers.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671EDDFM#10?

The R5F5671EDDFM#10 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 optimized pipeline and dual-bank flash with zero-wait access at 60 MHz or cache hits at 120 MHz - enabling deterministic real-time response in R5F5671EDDFM#10-based control loops.

Does the R5F5671EDDFM#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F5671EDDFM#10 includes hardware features required for IEC60730 Class B: oscillation-stop detection, CRC accelerator, independent watchdog timer (IWDTa) with window function, A/D self-diagnostic, and register write protection. These are documented in the R01DS0373EJ0120 datasheet and form the foundation for certified safety firmware on the R5F5671EDDFM#10.

What package type and pin count does the R5F5671EDDFM#10 use?

The R5F5671EDDFM#10 uses the PTLG0145JC-A package: a 145-pin Thin Fine-Pitch Land Grid Array measuring 9 × 9 mm with 0.65-mm pitch. It provides 111 general-purpose I/O pins (20 with 5-V tolerance), 1 dedicated input, and full support for pull-up, open-drain, and programmable drive strength - matching the mechanical and thermal requirements of compact industrial PCBs.

Can the R5F5671EDDFM#10 execute code directly from external serial flash memory?

Yes, the R5F5671EDDFM#10 supports XIP (execute-in-place) from external serial flash via its QSPIX interface, which implements quad-SPI, dual-SPI, and extended SPI protocols. Address width is selectable (8/16/24/32 bits), and the interface is designed for low-latency fetch - enabling faster boot and reduced on-chip flash dependency in R5F5671EDDFM#10 deployments.

What security features does the R5F5671EDDFM#10 provide for firmware protection?

The R5F5671EDDFM#10 integrates Trusted Secure IP (TSIP) with AES128/192/256, RSA, ECC, SHA256, MD5, TRNG, and hardware key protection against illicit copying. It also supports Trusted Memory (TM) to restrict instruction execution to protected code areas - collectively enabling secure boot, encrypted firmware updates, and runtime integrity verification on the R5F5671EDDFM#10.
