The device supports CAN FD (ISO 11898-1:2015), 12-bit A/D and D/A converters, real-time clock with sub-clock oscillator support, and operates across –40°C to +105°C for industrial and automotive control applications.

For engineers reviewing the R5F56609CGFB#30 datasheet, R5F56609CGFB#30 pinout, R5F56609CGFB#30 application, or R5F56609CGFB#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interfaces, integrated FPU, IEC60730 safety features (MPU, CRC, self-diagnostic A/D, IWDT), and full peripheral set including MTU3a, ELC, and REMC - all confirmed for the G-version temperature grade.

Technical Context

The R5F56609CGFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save capability. Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock oscillator, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocks: ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz, and ADCLK up to 60 MHz.

Peripheral integration includes a 9-channel MTU3a timer with complementary PWM and dead-time control, 8-channel DMACA, event-linking controller (ELC) supporting 83 internal signals, and dual-mode serial interfaces (SCIk/m/h, RSCI, RIIC, RSPId) with FIFO buffering and LIN/CAN FD protocol compliance. Safety-critical functions are reinforced by MPU, Trusted Memory (TM), register write protection, CAC, and DOCA.

The R5F56609CGFB#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 and hardware multiplier/divider. The R5F56609CGFB#30 sustains this speed with zero-wait-state access to both 1 Mbyte code flash and 128 Kbytes SRAM, enabling deterministic real-time response in demanding control applications.

Does the R5F56609CGFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609CGFB#30 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with bit rates up to 5 Mbps in FD mode. This capability is confirmed for the R5F56609CGFB#30 variant in the RX660 Group datasheet (R01DS0393EJ0100), and the module operates synchronously with PCLKA up to 120 MHz for precise timing alignment in automotive and industrial networks.

What package type and pin count does the R5F56609CGFB#30 use?

The R5F56609CGFB#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with designation PLQP0144KA-B - measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. This package provides 130 general-purpose I/O pins (with 5-V tolerance, open-drain, and pull-up options), JTAG and FINE debug interfaces, and dedicated terminals for main/sub-clock oscillators and power domains.

Is the R5F56609CGFB#30 qualified for extended temperature operation, and what is its grade?

Yes, the R5F56609CGFB#30 is the G-version device, rated for operation from –40°C to +105°C. This extended temperature grade is explicitly defined in the RX660 Group datasheet (R01DS0393EJ0100, page 9) and validated across all integrated peripherals - including the 12-bit A/D converter, CAN FD transceiver, and real-time clock - making it suitable for under-hood automotive and high-ambient industrial environments.

What safety features does the R5F56609CGFB#30 include for IEC60730 compliance?

The R5F56609CGFB#30 integrates multiple hardware-based safety features for IEC60730 Class B compliance: memory protection unit (MPU), Trusted Memory (TM) for code protection, CRC calculator (CRCA), clock accuracy measurement circuit (CAC), data operation circuit (DOCA), independent watchdog timer (IWDT) with window function, and A/D converter self-diagnostic capabilities. These are documented in the R5F56609CGFB#30 datasheet sections covering safety functions and are enabled without external components.
