FAQ

What is the maximum operating frequency of the R5F56609DDFB#10?

The R5F56609DDFB#10 operates at a maximum frequency of 120 MHz using its RXv3 CPU core. This is achieved with zero-wait-state access to both 1 Mbyte code flash and 128 Kbytes SRAM, enabling deterministic execution of complex control algorithms. The device achieves 709 CoreMark at this speed, confirming sustained real-time performance under full load.

Does the R5F56609DDFB#10 support CAN FD communication?

Yes, the R5F56609DDFB#10 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It delivers up to 5 Mbps data phase transfer rates and includes hardware message filtering, FIFO buffering, and error confinement - making it suitable for high-bandwidth diagnostics and actuator control in automotive and industrial networks.

What package type is used for the R5F56609DDFB#10?

The R5F56609DDFB#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package measuring 20 × 20 mm with 0.5 mm pitch. This package includes bonded XT1/XT2 pins for sub-clock oscillator support and provides 130 general-purpose I/O pins with 5-V tolerance, open-drain capability, and programmable pull-up resistors.

Can the R5F56609DDFB#10 operate with a 5 V supply?
