For engineers reviewing the R5F56609GGFP#30 datasheet, R5F56609GGFP#30 pinout, R5F56609GGFP#30 application, or R5F56609GGFP#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), integrated FPU, ELC event-driven peripheral coordination, and dual debugging interfaces (JTAG + FINE).

Technical Context

The R5F56609GGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. It supports little-endian or big-endian data arrangement and includes on-chip 32×32→64-bit multiplier and 32/32→32-bit divider.

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-based domain clocks: ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz, PCLKD up to 60 MHz, and BCLK up to 40 MHz - enabling precise peripheral timing isolation.

FAQ

What is the maximum operating frequency and core architecture of the R5F56609GGFP#30?

The R5F56609GGFP#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and includes a single-precision IEEE 754 floating-point unit, 16-register bank save, and support for both little-endian and big-endian data arrangements. The R5F56609GGFP#30 achieves deterministic real-time behavior through its zero-wait-state memory subsystem and event-driven ELC architecture.

Does the R5F56609GGFP#30 support real-time clock (RTC) functionality, and what oscillator is required?

Yes, the R5F56609GGFP#30 supports RTC functionality using the sub-clock oscillator (SOSC), which requires an external 32.768 kHz crystal connected to XT1/XT2 pins. The RTC operates in deep software standby mode, maintaining timekeeping while the CPU and most peripherals are powered down. The R5F56609GGFP#30's RTC includes calendar functions, alarm interrupts, time capture on external events, and leap-year compensation - all confirmed in the RX660 Group hardware manual.

What communication interfaces does the R5F56609GGFP#30 include, and is CAN FD supported?

The R5F56609GGFP#30 includes one CAN FD channel compliant with ISO 11898-1:2015 (supporting both standard and extended frames), 13 SCI channels (with async/sync/SmartCard/SPI/I²C modes), two RIIC interfaces (400 kbps Fast Mode), and one RSPId interface (30 Mbps). Its CAN FD module supports bit rates up to 5 Mbps and includes built-in message RAM with flexible filtering - verified in the R01DS0393EJ0100 datasheet section 1.1 and Table 1.2.

What are the memory resources available on the R5F56609GGFP#30?

The R5F56609GGFP#30 integrates 1 MB of on-chip code flash memory (accessible with zero wait states at 120 MHz), 128 KB of SRAM (also zero wait states), and 32 KB of reprogrammable data flash memory rated for 100,000 erase/write cycles. It also includes a 12-byte unique ID and supports Trusted Memory (TM) protection for secure firmware storage. These memory specifications are explicitly listed in Table 1.1 of the R01DS0393EJ0100 datasheet.

Is the R5F56609GGFP#30 qualified for industrial temperature operation, and what package does it use?

Yes, the R5F56609GGFP#30 is rated for industrial operation from –40°C to +105°C (G-grade), as indicated by the "G" in its part number. It uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch, and includes both JTAG and FINE debugging interfaces. This package configuration supports full peripheral complement including sub-clock oscillator and RTC - confirmed in Table 1.2 and package dimension diagrams of the R01DS0393EJ0100 datasheet.
