FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609FGFB#10?

The R5F56609FGFB#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, barrel shifter, and optimized memory subsystem enabling no-wait access to both 1 Mbyte code flash and 128 Kbytes SRAM at full speed.

Does the R5F56609FGFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56609FGFB#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps in FD mode and maintains backward compatibility with classical CAN 2.0B networks-making it suitable for next-generation automotive and industrial communication backbones.

What is the purpose of the Trusted Memory (TM) function in the R5F56609FGFB#10?

The Trusted Memory (TM) function in the R5F56609FGFB#10 protects designated code flash regions against unauthorized read-out. When enabled, only the CPU can fetch instructions from the TM target area-debuggers, JTAG interfaces, and background programming tools cannot access its contents, ensuring intellectual property and firmware integrity in production devices.

How many analog input channels does the R5F56609FGFB#10 support, and what is the minimum A/D conversion time?

The R5F56609FGFB#10 supports 24 analog input channels via its 12-bit S12ADH module. At maximum ADCLK of 60 MHz, the minimum conversion time per channel is 0.9 µs-enabling high-speed acquisition for closed-loop control and power quality monitoring in real-time applications.

Is the R5F56609FGFB#10 qualified for extended temperature operation, and what is its grade?

Yes, the R5F56609FGFB#10 is rated for industrial extended temperature operation as a G-version device, specified from –40°C to +105°C. This rating applies to the full 144-pin LFQFP package (PLQP0144KA-B) and is validated across all integrated peripherals, including CAN FD, RTC, and analog subsystems.
