FAQ

What is the maximum operating frequency and core architecture of the R5F56609DDFM#30?

The R5F56609DDFM#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and includes a hardware single-precision floating-point unit compliant with IEEE 754. The core supports collective register bank save, memory protection unit (MPU), and 113 instructions including DSP extensions - all confirmed in the R01DS0393EJ0100 datasheet Rev.1.00.

Does the R5F56609DDFM#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609DDFM#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B. This capability is explicitly documented in the "Communication function" section of the R01DS0393EJ0100 datasheet.

What are the memory resources available on the R5F56609DDFM#30?

The R5F56609DDFM#30 provides 1 Mbyte of on-chip code flash memory (with no-wait access at 120 MHz), 32 Kbytes of reprogrammable data flash (rated for 100,000 erase/write cycles), and 128 Kbytes of SRAM (no-wait access). These values are specified in Table 1.1 of the R01DS0393EJ0100 datasheet and apply specifically to the 144-pin package variant.

What debugging interfaces does the R5F56609DDFM#30 support?

The R5F56609DDFM#30 supports both JTAG and FINE (one-wire) debugging interfaces. JTAG enables full-featured emulation, boundary scan, and flash programming, while FINE provides minimal-pin debug and programming capability. Both interfaces are physically present on the 144-pin LFQFP package and are detailed in Section 1.1 of the R01DS0393EJ0100 datasheet.

Is the R5F56609DDFM#30 qualified for industrial temperature range, and what is its operating voltage?

Yes, the R5F56609DDFM#30 is rated for the industrial temperature range of –40°C to +85°C (D-version) and operates from a single 2.7 V to 5.5 V supply. The analog supply AVCC0 must be ≥ VCC and falls within 3.0 V to 5.5 V - ensuring compatibility with 3.3 V and 5 V system rails. This specification is confirmed in Table 1.1 and Section 1.2 of the R01DS0393EJ0100 datasheet.
