FAQ

What is the maximum operating frequency and CoreMark score of the R5F56719DDFM#10?

The R5F56719DDFM#10 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and optimized memory subsystem enabling zero-wait access to SRAM and cache-hit flash reads. The R5F56719DDFM#10 sustains this throughput across real-world workloads involving floating-point math, interrupt handling, and peripheral DMA transfers.

Does the R5F56719DDFM#10 support secure boot and cryptographic operations?

Yes, the R5F56719DDFM#10 integrates Trusted Secure IP (TSIP) providing hardware-accelerated AES-128/192/256, SHA-256, ECDSA, RSA, and TRNG functions. It supports secure boot verification, encrypted firmware image decryption, and key protection against extraction - all without exposing keys to software. The R5F56719DDFM#10 uses these capabilities to enforce authenticated firmware updates and runtime integrity checks required for IEC60730 Class B certification.

What package type and pin count does the R5F56719DDFM#10 use?

The R5F56719DDFM#10 is packaged in PLQP0144KA-B: a 144-pin Low-profile Quad Flat Package with 20 mm × 20 mm body size, 0.50 mm pitch, and exposed thermal pad. It provides 113 general-purpose I/O pins (5-V tolerant on 20 pins), plus dedicated power, clock, reset, and debug signals. This package is pin-compatible across the RX671 Group's 144-pin variants, enabling scalable design reuse.

Which communication interfaces are integrated into the R5F56719DDFM#10?

The R5F56719DDFM#10 integrates USB 2.0 Full-Speed host/function/OTG, 2-channel CAN (ISO11898-1 compliant), SD host interface (25 MB/s), quad-SPI (QSPIX), 13-channel SCI (including LIN/Manchester), 3-channel RSPId, 1-channel RSPIA, 3-channel RIIC (1× fast-mode-plus), and 1-channel RIICHS (3.4 Mbps). These interfaces enable direct connectivity to displays, sensors, actuators, legacy fieldbuses, and secure cloud uplinks without external bridge ICs - all managed via the Event Link Controller for CPU-offload operation.

How does the R5F56719DDFM#10 support functional safety standards like IEC60730?

The R5F56719DDFM#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, independent windowed watchdog timer (IWDTa), CRC calculation unit, self-diagnostic A/D converter with internal reference generation, memory protection unit (MPU), and register write protection. These allow runtime verification of clock integrity, memory correctness, analog subsystem health, and critical register states - all documented in Renesas' Functional Safety Manual for the RX671 Group. The R5F56719DDFM#10 is certified for use in safety-related firmware implementations.
