FAQ

What is the maximum operating frequency and CoreMark score of the R5F56719DGLJ#20?

The R5F56719DGLJ#20 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 single-cycle instruction execution, 16 general-purpose registers, and efficient pipeline design - enabling deterministic real-time response in demanding industrial applications. The R5F56719DGLJ#20 maintains this speed across its full voltage range (2.7–3.6 V) and temperature range (–40°C to +105°C).

Does the R5F56719DGLJ#20 support secure boot and cryptographic operations?

Yes, the R5F56719DGLJ#20 integrates Trusted Secure IP (TSIP) hardware acceleration for AES128/192/256, SHA256, MD5, GHASH, RSA, ECC, and TRNG. It supports secure boot verification, encrypted firmware storage, and key protection against physical extraction. These features are documented in the R01DS0373EJ0120 datasheet and enable compliance with IEC60730 Class B and industrial cybersecurity standards - critical for protecting the R5F56719DGLJ#20-based systems in field-deployed equipment.

What package type and pin count does the R5F56719DGLJ#20 use?

The R5F56719DGLJ#20 uses the PTLG0145JC-A package: a 145-pin thin fine-pitch land grid array (TFLGA) measuring 9 × 9 mm with 0.65-mm pitch. It provides 111 general-purpose I/O pins (including 20 with 5-V tolerance), dedicated USB/SDHI/QSPIX interfaces, and power/backup domains aligned to Renesas' RX671 Group pinout standard. This package is rated for industrial G-grade operation (–40°C to +105°C).

Can the R5F56719DGLJ#20 execute code directly from external serial flash memory?

Yes, the R5F56719DGLJ#20 supports execute-in-place (XIP) from external serial flash via its QSPIX interface. The QSPIX module implements quad-SPI, dual-SPI, and extended SPI protocols with configurable address width (8–32 bits), enabling fast, low-pin-count firmware execution without loading into internal RAM. This capability reduces external memory footprint and accelerates boot time - a key advantage confirmed in Section 1.1 and Table 1.1 of the R01DS0373EJ0120 datasheet for the R5F56719DGLJ#20.

What safety certifications and diagnostic features does the R5F56719DGLJ#20 provide for IEC60730 compliance?

The R5F56719DGLJ#20 includes multiple hardware-level features for IEC60730 Class B compliance: oscillation-stoppage detection, CRC-A accelerator, independent watchdog timer (IWDTa) with windowing, A/D converter self-diagnostic function, and register write protection. These are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0373EJ0120 datasheet. Together, they enable runtime verification of clock integrity, memory consistency, analog subsystem health, and critical register state - essential for validating the R5F56719DGLJ#20 in safety-critical industrial control applications.
