Technical Context
The R5F5671EHDFP#30 implements the RXv3 CPU core with 113 instructions, 16 general-purpose 32-bit registers, and hardware-accelerated 32×32→64-bit multiply and 32÷32 division. Its memory subsystem includes 2 MB code flash (no-wait access ≤60 MHz, 1-wait at 120 MHz), 8 KB data flash rated for 100,000 erase/write cycles, and 384 KB zero-wait-state SRAM.
Peripherals are clocked across four domains: ICLK (up to 120 MHz for CPU/QSPIX), PCLKA (up to 120 MHz for MTU/RSPI/RIICHS), PCLKB (up to 60 MHz for most timers and communication interfaces), and PCLKC/PCLKD (up to 60 MHz for S12AD units). The device supports full-speed USB 2.0 host/function/OTG, two ISO11898-1 CAN channels (32 mailboxes each), and a dedicated remote control signal receiver (REMCa) with 8-byte pattern-matching buffer.

The R5F5671EHDFP#30 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark under benchmark conditions. This performance stems from the RXv3 CPU core's 113-instruction set, hardware multiplier/divider, barrel shifter, and efficient pipeline - enabling deterministic real-time response in industrial control applications where R5F5671EHDFP#30 serves as the primary system controller.
Does the R5F5671EHDFP#30 support secure firmware updates and cryptographic operations?
Yes, the R5F5671EHDFP#30 integrates Trusted Secure IP (TSIP) with hardware-accelerated AES128/192/256, SHA256, RSA, ECC, and a true random number generator. These features enable secure boot validation, encrypted OTA firmware updates, and protected key storage - critical for applications like smart meters where R5F5671EHDFP#30 must prevent unauthorized firmware modification or data exfiltration.
What package type and temperature grade does the R5F5671EHDFP#30 use?
The R5F5671EHDFP#30 uses the PLQP0144KA-B package: a 144-pin LFQFP with 20 × 20 mm body and 0.50 mm pitch. It is rated for the D-version industrial temperature range of –40°C to +85°C, making it suitable for deployment in harsh environments such as factory floors or outdoor utility enclosures where R5F5671EHDFP#30 operates reliably without derating.
How many CAN channels and mailboxes does the R5F5671EHDFP#30 support?
The R5F5671EHDFP#30 integrates two independent CAN modules compliant with ISO11898-1, each supporting 32 message mailboxes. This allows concurrent handling of multiple CAN IDs and prioritized message filtering - essential for R5F5671EHDFP#30-based systems like industrial HMIs that manage both device-level control traffic and higher-layer diagnostic messaging over separate CAN buses.
Can the R5F5671EHDFP#30 execute code directly from external serial flash memory?
Yes, the R5F5671EHDFP#30 includes a QSPIX interface supporting extended SPI, dual-SPI, and quad-SPI protocols with selectable 8–32-bit addressing. This enables eXecute-In-Place (XIP) from external serial flash, allowing R5F5671EHDFP#30 to run application code directly from high-density, low-cost external memory - ideal for GUI-rich HMIs or firmware-over-the-air update architectures where on-chip flash is reserved for bootloader and critical routines.
