FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671EDGFM#10?

The R5F5671EDGFM#10 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark under those conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 16-register bank save, and optimized pipeline - enabling deterministic real-time response in applications like industrial motion control and HMI rendering where latency matters.

Does the R5F5671EDGFM#10 support secure boot and cryptographic acceleration?

Yes, the R5F5671EDGFM#10 integrates Trusted Secure IP (TSIP) with hardware-accelerated AES-128/192/256, RSA, ECC, SHA256, and a true random number generator (TRNG). These features enable secure boot verification, encrypted firmware updates, and runtime key protection - critical for meeting IEC60730 Class B requirements in smart meters and medical devices using the R5F5671EDGFM#10.

What package type and pin count does the R5F5671EDGFM#10 use?

The R5F5671EDGFM#10 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, 20 of which are 5-V tolerant, and supports open-drain outputs and internal pull-up resistors - making it suitable for mixed-voltage industrial interfaces and legacy bus compatibility without level shifters.

Can the R5F5671EDGFM#10 execute code directly from external serial flash memory?

Yes, the R5F5671EDGFM#10 includes a Quad-SPI memory interface (QSPIX) that supports XIP (execute-in-place) from serial flash using extended SPI, dual-SPI, and quad-SPI protocols. With 32-bit address width support and hardware prefetch, the R5F5671EDGFM#10 enables fast, secure boot from encrypted external flash - reducing reliance on internal flash for large firmware images.

How does the R5F5671EDGFM#10 meet IEC60730 functional safety requirements?

The R5F5671EDGFM#10 meets IEC60730 Class B requirements through integrated safety mechanisms: oscillation-stoppage detection, hardware CRC accelerator, independent watchdog timer (IWDTa) with window function, register write protection, and self-diagnostic A/D converter that generates internal test voltages. These features are documented in the R5F5671EDGFM#10 datasheet and supported by Renesas' safety manual for certified system design.
