FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671EHDNE#30?

The R5F5671EHDNE#30 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with optimized pipeline, double-precision FPU, and zero-wait-state access to 384 KB SRAM - enabling deterministic execution for real-time industrial firmware. The R5F5671EHDNE#30 maintains this throughput across voltage (2.7–3.6 V) and temperature (–40°C to +85°C) ranges specified for the D-version.

Does the R5F5671EHDNE#30 support secure firmware updates and cryptographic operations?

Yes, the R5F5671EHDNE#30 integrates Trusted Secure IP (TSIP) with hardware-accelerated AES128/192/256, SHA256, RSA, ECC, and a true-random number generator (TRNG). It supports secure boot, encrypted OTA updates, and key protection against illicit copying. These capabilities are validated per IEC60730 Class B requirements, and the R5F5671EHDNE#30 includes register write protection and CRC acceleration to ensure runtime integrity - making it suitable for certified industrial and energy applications.

What package type and pin count does the R5F5671EHDNE#30 use?

The R5F5671EHDNE#30 uses a 145-pin TFLGA package (PTLG0145JC-A), measuring 9 × 9 mm with 0.65-mm pitch. It provides 111 general-purpose I/O pins, including 20 with 5-V tolerance, configurable pull-ups, and open-drain outputs. This package is distinct from other RX671 variants (e.g., 144-pin LFQFP or 100-pin TFLGA) and is specifically designated for high-peripheral-count designs requiring SDHI, QSPIX, and dual CAN in minimal footprint.

Can the R5F5671EHDNE#30 operate with battery backup for RTC and registers?

Yes, the R5F5671EHDNE#30 supports battery backup via the VBATT pin, maintaining operation of the sub-clock oscillator, real-time clock (RTC), and backup registers during main power loss. The RTC retains timekeeping accuracy (±30 sec/year) and supports alarm, periodic, and carry interrupts - essential for timestamped logging, tamper detection, and scheduled wake-up in energy-metering and industrial monitoring systems using the R5F5671EHDNE#30.

Which communication interfaces are supported by the R5F5671EHDNE#30 for industrial networking?

The R5F5671EHDNE#30 supports CAN (2 channels, ISO11898-1 compliant, 32 mailboxes per channel), USB 2.0 Full-Speed host/function/OTG, SD host interface (25 MB/s), QSPIX for serial flash, and multiple UART/SPI/I²C variants (including RIICHS at 3.4 Mbps). These interfaces enable robust industrial networking - e.g., CAN for fieldbus connectivity, USB for configuration, SD for local data storage, and QSPIX for fast firmware loading - all integrated into a single R5F5671EHDNE#30 die without external transceivers.
