FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671EDDLJ#20?

The R5F5671EDDLJ#20 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark in benchmark testing. This performance stems from the RXv3 CPU core's optimized pipeline, zero-wait-state 384 KB SRAM, and dual-bank flash architecture - enabling deterministic execution for real-time industrial firmware. The R5F5671EDDLJ#20 delivers consistent throughput even under interrupt-heavy workloads typical in CAN/USB protocol stacks.

Does the R5F5671EDDLJ#20 support secure boot and cryptographic acceleration?

Yes, the R5F5671EDDLJ#20 integrates Trusted Secure IP (TSIP) with hardware-accelerated AES128/192/256, RSA, ECC, SHA256, MD5, and a true random number generator (TRNG). It supports secure boot via encrypted firmware validation and prevents illicit key copying - meeting IEC60730 Class B requirements. These capabilities are natively accessible through Renesas' Secure Boot Manager and Crypto Library, ensuring the R5F5671EDDLJ#20 meets stringent security mandates for industrial IoT deployments.

What package type and pin count does the R5F5671EDDLJ#20 use?

The R5F5671EDDLJ#20 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 0.50-mm pitch and 20 × 20 mm body size. This LQFP variant supports industrial temperature range (−40°C to +85°C), includes an exposed thermal pad for enhanced heat dissipation, and is compatible with standard reflow soldering processes. All R5F5671EDDLJ#20 pin functions are documented in Renesas' R01DS0373EJ0120 datasheet, Section 5.

Can the R5F5671EDDLJ#20 interface directly with SD cards and serial flash memory?

Yes, the R5F5671EDDLJ#20 includes a dedicated SD host interface (SDHI) supporting 1- and 4-bit SD buses at up to 25 MB/s (high-speed mode), compliant with SD Physical Layer Spec v3.01. It also features QSPIX - a quad-SPI memory interface supporting extended SPI, dual-SPI, and quad-SPI protocols - enabling execute-in-place (XIP) from external serial flash. Both interfaces require no external level shifters or glue logic, simplifying design for R5F5671EDDLJ#20-based data loggers and firmware-upgradable devices.

How does the R5F5671EDDLJ#20 support functional safety standards like IEC60730?

The R5F5671EDDLJ#20 includes multiple hardware features certified for IEC60730 Class B compliance: oscillation-stoppage detection, CRC-A accelerator, independent watchdog timer (IWDTa) with window function, A/D converter self-diagnostic, memory protection unit (MPU), and register write protection. These mechanisms enable runtime fault detection and recovery without software polling - reducing certification effort for household appliances and industrial controls. Renesas provides IEC60730-compliant software libraries and documentation specifically for the R5F5671EDDLJ#20.
