For engineers reviewing the R5F56609FDFP#30 datasheet, R5F56609FDFP#30 pinout, R5F56609FDFP#30 application, or R5F56609FDFP#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interfaces, 2.7–5.5 V single-supply operation, deep software standby mode with RTC persistence, and integrated safety features including MPU, Trusted Memory, and CRC calculator.

Technical Context

The R5F56609FDFP#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. It supports little-endian or big-endian data arrangement and includes a 32×32→64-bit multiplier, 32/32→32-bit divider, and barrel shifter.

Its clock system integrates main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL synthesis enabling ICLK up to 120 MHz and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/PCLKD up to 60 MHz). The ELC enables interrupt-free inter-module event linking across 83 internal signals.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609FDFP#30?

The R5F56609FDFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing at that speed. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32×32→64-bit multiplier, and optimized pipeline - enabling deterministic real-time response in applications like motor control and protocol processing where the R5F56609FDFP#30 is commonly deployed.

Does the R5F56609FDFP#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609FDFP#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. Its CANFD peripheral includes message filtering, FIFO buffering, and error handling logic - making the R5F56609FDFP#30 suitable for modern industrial networks requiring higher bandwidth than classical CAN, such as factory automation and energy infrastructure communication.

What package type and pin count does the R5F56609FDFP#30 use?

The R5F56609FDFP#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0144KA-B, measuring 20 × 20 mm with 0.5 mm lead pitch. This package includes a thermal pad and supports 5-V tolerant I/O, making the R5F56609FDFP#30 compatible with mixed-voltage system designs and simplifying level-shifting requirements in industrial interfaces.

Is the real-time clock (RTCC) functional on the R5F56609FDFP#30, and what oscillator does it require?

Yes, the RTCC is fully functional on the R5F56609FDFP#30 and requires connection to a 32.768 kHz crystal via the RTCXTAL/RTCXTAL pins. The sub-clock oscillator is present in this variant, enabling calendar/timekeeping, alarm interrupts, periodic wake-up from deep software standby, and time-capture functionality - all critical for time-sensitive applications like smart metering where the R5F56609FDFP#30 is frequently used.

What safety and reliability features does the R5F56609FDFP#30 include for IEC60730 compliance?

The R5F56609FDFP#30 includes multiple hardware-assisted safety features for IEC60730 Class B compliance: oscillation-stoppage detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA), register write protection, and memory protection unit (MPU). These capabilities - documented in the R5F56609FDFP#30 datasheet and user manual - allow developers to implement robust self-test routines and fault mitigation strategies without external components.
