It integrates 1 Mbyte of on-chip code flash (no-wait access), 128 Kbytes of SRAM, 32 Kbytes of reprogrammable data flash, and supports CAN FD, 12-bit A/D (24 channels), 12-bit D/A (2 channels), RTC, and remote control signal reception. It targets industrial motor control and embedded automation requiring deterministic real-time response, functional safety support (IEC60730), and mixed-signal integration.

For engineers reviewing the R5F56604CGFM#10 datasheet, R5F56604CGFM#10 pinout, R5F56604CGFM#10 application, or R5F56604CGFM#10 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package with 130 GPIOs (4× 5-V tolerant), dual-clock domain architecture (ICLK up to 120 MHz, PCLKA/B/D up to 120/60/60 MHz), ELC-driven event-triggered peripheral coordination, and integrated memory protection unit (MPU) for robust firmware partitioning.

Technical Context

The R5F56604CGFM#10 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 includes main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division settings per bus domain (ICLK, PCLKA, PCLKB, PCLKD, FCLK, BCLK).

Peripheral coordination is managed via the Event Link Controller (ELC), enabling 83 internal event signals to trigger timer operations, A/D conversions, or port state changes without CPU intervention. Safety-critical features include MPU-based memory isolation, Trusted Memory (TM) for code flash read protection, CRC calculator (CRCA) with configurable polynomials, and hardware-accelerated self-diagnostic functions for A/D input disconnection and oscillator stoppage detection.

The R5F56604CGFM#10 features a 32-bit RXv3 CPU core with a maximum operating frequency of 120 MHz, achieving 709 CoreMark performance. It supports single-cycle instruction execution, IEEE 754-compliant single-precision floating-point operations, and collective register bank save for rapid context switching-enabling deterministic real-time execution in demanding industrial control applications. The R5F56604CGFM#10 uses an advanced pipeline with 113 instructions, including DSP extensions and barrel shifter functionality.

Does the R5F56604CGFM#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CGFM#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frame formats. It operates at data rates up to 5 Mbps in FD mode and maintains backward compatibility with classical CAN. The module includes dedicated TX/RX pins (CAN0TX/CAN0RX), message RAM with flexible filtering, and error handling features required for industrial network gateways and automotive subsystems. This capability is confirmed in the R01DS0393EJ0100 datasheet for the RX660 Group.

What package type and pin count does the R5F56604CGFM#10 use?

The R5F56604CGFM#10 is housed in a 144-pin Low-profile Quad Flat Package (LFQFP) with designation PLQP0144KA-B: 20 × 20 mm body, 0.5 mm lead pitch, and exposed thermal pad. It provides 130 general-purpose I/O pins, including 4 pins with 5-V tolerance, configurable pull-up resistors, open-drain outputs, and switchable drive strength-optimized for industrial PCB layouts requiring noise immunity and mixed-voltage interfacing. This package is explicitly listed in Table 1.1 and Table 1.2 of the R01DS0393EJ0100 datasheet.

How does the R5F56604CGFM#10 support functional safety standards like IEC60730?

The R5F56604CGFM#10 includes multiple hardware features certified for IEC60730 Class B compliance: memory protection unit (MPU) for runtime memory access control, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA) with configurable polynomials, data operation circuit (DOCA) for register comparison, and self-diagnostic functions for A/D input disconnection and oscillator stoppage detection. These are documented in Section 1.1 and safety-related chapters of the R01DS0393EJ0100 datasheet, enabling developers to implement robust safety monitors without external components.

What debugging interfaces are available on the R5F56604CGFM#10?

The R5F56604CGFM#10 supports the FINE (Fast In-Circuit Emulator) one-line debugging interface but does not include the JTAG interface-confirmed by package variant comparisons in Table 1.2 of the R01DS0393EJ0100 datasheet. FINE enables full breakpoint, watchpoint, and memory access capabilities with minimal pin count overhead, making it suitable for space-constrained designs where JTAG trace bandwidth is not required. Development tools such as Renesas E2 studio and CS+ fully support FINE-based debugging of the R5F56604CGFM#10.
