The R5F56609DDFB#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32×32→64-bit hardware multiplier, and integrated FPU. The R5F56609DDFB#30 sustains this speed with zero-wait-state access to both 1 Mbyte code flash and 128 Kbytes SRAM - critical for deterministic real-time control loops.

Does the R5F56609DDFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609DDFB#30 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B. The R5F56609DDFB#30 implements hardware message filtering, TX/RX FIFOs, and error confinement - essential for automotive and industrial network gateways.

What are the key safety features built into the R5F56609DDFB#30 for IEC 60730 compliance?

The R5F56609DDFB#30 integrates multiple hardware safety features aligned with IEC 60730 Class B: memory protection unit (MPU) with eight configurable regions, Trusted Memory (TM) for code flash read protection, CRCA for CRC-8/32 computation, clock accuracy measurement circuit (CAC), oscillation-stop detection, and register write protection. These features are documented in Renesas R01DS0393EJ0100 and enable systematic fault detection - reducing software diagnostic overhead for the R5F56609DDFB#30 in safety-critical firmware.

What package type and pin count does the R5F56609DDFB#30 use, and does it include JTAG?

The R5F56609DDFB#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP), designated PLQP0144KA-B, with 20 × 20 mm body and 0.5 mm pitch. It includes full JTAG (TMS/TDI/TDO/TCK) and FINE debugging interfaces, and supports the sub-clock oscillator (XT1/XT2) - confirmed in Renesas datasheet R01DS0393EJ0100 Table 1.2. This configuration enables real-time trace, on-chip programming, and RTC functionality in the R5F56609DDFB#30.

How much on-chip memory does the R5F56609DDFB#30 provide, and what are its endurance specifications?

The R5F56609DDFB#30 provides 1 Mbyte of on-chip code flash memory (no-wait access at 120 MHz), 128 Kbytes of SRAM (no-wait), and 32 Kbytes of data flash memory rated for 100,000 program/erase cycles. The data flash supports background operation (BGO), allowing concurrent execution and reprogramming - essential for field firmware updates. All memory blocks are protected by the R5F56609DDFB#30's MPU and Trusted Memory features to prevent unauthorized access or corruption.
