Renesas R5F56609HGFB#30

Overview

R5F56609HGFB#30 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz maximum operating frequency, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and hardware FPU. It targets industrial control, motor drive, and safety-critical embedded systems requiring IEC60730 compliance, real-time responsiveness, and mixed-signal integration.

For engineers reviewing the R5F56609HGFB#30 datasheet, R5F56609HGFB#30 pinout, R5F56609HGFB#30 application, or R5F56609HGFB#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, dual D/A output capability, sub-clock oscillator support for RTC operation, JTAG/FINE debug interface, and full CAN FD compliance per ISO 11898-1:2015.

Technical Context

The R5F56609HGFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system integrates main (8–24 MHz crystal), sub-clock (32.768 kHz), and high-speed on-chip oscillators (16/18/20 MHz), with PLL multiplication enabling 120 MHz ICLK and independent peripheral clocks up to 120 MHz (PCLKA) or 60 MHz (PCLKB/PCLKD).

It features event-driven architecture via the Event Link Controller (ELC), supporting 83 internal event signals for interrupt-free inter-module coordination - e.g., MTU3a timer triggers A/D conversion or REMC pattern detection initiates GPIO state change - while maintaining deep software standby with RTC active and IWDT running on dedicated 120 kHz oscillator.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609HGFB#30?

The R5F56609HGFB#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, barrel shifter, and IEEE 754-compliant floating-point unit - all verified in the official Renesas datasheet R01DS0393EJ0100.

Does the R5F56609HGFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609HGFB#30 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames, bit-rate switching, and FD data payloads. This is confirmed in the "Communication function" section of the R01DS0393EJ0100 datasheet, and the device requires external CAN transceivers for physical layer interfacing.

What package type and pin count does the R5F56609HGFB#30 use?

The R5F56609HGFB#30 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size and 0.5 mm pitch. This is explicitly stated in Table 1.1 and Figure 1.1 of the R01DS0393EJ0100 datasheet, and corresponds to the "H" prefix denoting 144-pin LFQFP in Renesas' part numbering scheme.

Does the R5F56609HGFB#30 include a real-time clock (RTC), and what oscillator does it require?

Yes, the R5F56609HGFB#30 includes a real-time clock (RTCC) module that requires connection to a 32.768 kHz crystal via the RTCXTAL/RTCEXTAL pins. As noted in datasheet Notes 1 and 2, RTC functionality is enabled only in packages with sub-clock oscillator support - which the R5F56609HGFB#30 (144-pin, "H" variant) provides.

What safety and security features are built into the R5F56609HGFB#30 for IEC60730 compliance?

The R5F56609HGFB#30 integrates multiple IEC60730 Class B support features: oscillation-stop detection, A/D converter self-diagnosis and disconnection detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, memory protection unit (MPU), Trusted Memory (TM), CRC calculator (CRCA), and register write protection. These are documented in Section 1.1 and Table 1.1 of R01DS0393EJ0100.
