FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609FGFB#30?

The R5F56609FGFB#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This score reflects its RXv3 CPU core efficiency, including optimized instruction pipeline, collective register bank save, and integrated 32-bit multiplier/divider. The R5F56609FGFB#30 sustains this performance with zero-wait-state access to both 1 Mbyte code flash and 128 Kbytes SRAM at full speed.

Does the R5F56609FGFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609FGFB#30 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frame formats. It enables data rates up to 5 Mbps in the FD data phase while maintaining backward compatibility with classical CAN networks. The R5F56609FGFB#30 implements hardware-based bit-rate switching and error confinement, essential for real-time industrial communication.

What are the analog capabilities of the R5F56609FGFB#30, particularly regarding A/D and D/A converters?

The R5F56609FGFB#30 integrates a 24-channel 12-bit A/D converter (S12ADH) with minimum 0.9 µs conversion time at 60 MHz ADCLK, and two independent 12-bit D/A converter channels (R12DAb) with output range 0 V to AVCC0. Critically, the R5F56609FGFB#30 allows either D/A channel to serve as a programmable reference voltage for its four-channel analog comparator (CMPC), enabling adaptive threshold detection in sensor interfaces.

How does the R5F56609FGFB#30 support functional safety standards like IEC 60730?

The R5F56609FGFB#30 provides hardware-level support for IEC 60730 Class B compliance, including oscillation-stoppage detection, self-diagnostic A/D input disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with window function, RAM test assistance via DOC, and register write protection. These features are documented in the R5F56609FGFB#30 datasheet and enable certified safety routines without requiring external components.

What package type and pin count does the R5F56609FGFB#30 use, and does it include JTAG debugging?

The R5F56609FGFB#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP), designated PLQP0144KA-B (20 × 20 mm, 0.5 mm pitch), and includes full JTAG debugging support alongside the FINE one-wire interface. This package variant provides 130 general-purpose I/O pins, 4×5-V tolerant inputs, integrated sub-clock oscillator terminals, and all required JTAG signals (TMS, TDI, TDO, TCK) for boundary-scan and real-time trace.
