Renesas R5F56604FGFP#10

Overview

R5F56604FGFP#10 from Renesas is a 120-MHz 32-bit RXv3 core MCU with on-chip FPU, 1 Mbyte code flash, 128 Kbytes SRAM, and 32 Kbytes data flash. It integrates CAN FD (ISO 11898-1:2015), 12-bit A/D (24 channels), 12-bit D/A (2 channels), RTC with sub-clock support, and ELC for event-driven peripheral coordination-targeted for industrial control and automotive body electronics requiring IEC60730 compliance.

For engineers reviewing the R5F56604FGFP#10 datasheet, R5F56604FGFP#10 pinout, R5F56604FGFP#10 application, or R5F56604FGFP#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package with 130 GPIOs (4× 5-V tolerant), deep software standby mode with RTC persistence, dual watchdog timers (WDTA + IWDTa), and hardware-accelerated trigonometric functions (TFU) for motor control algorithms.

Technical Context

The R5F56604FGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16 register banks for fast context switching. Its clock system supports independent domain scaling: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for MTU3a/RSPI/SCI10–11, PCLKB up to 60 MHz for TMR/CMT/CMTW, and PCLKD up to 60 MHz for S12ADH.

Peripheral coordination is managed via the Event Link Controller (ELC), which enables 83 internal event signals-including A/D conversion triggers, timer overflows, and interrupt requests-to initiate module operations without CPU intervention. The MCU includes Trusted Memory (TM) protection for secure code execution and MPU-based memory isolation across eight configurable regions.

FAQ

What is the maximum operating frequency and core architecture of the R5F56604FGFP#10?

The R5F56604FGFP#10 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 (FPU), 16 register banks for fast context switching, and support for both little-endian and big-endian data formats. This architecture enables deterministic real-time execution in motor control and industrial automation applications.

Does the R5F56604FGFP#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604FGFP#10 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. It includes built-in message filtering, FIFO buffering, and error handling logic-enabling robust communication in automotive body networks and industrial fieldbus systems without requiring external CAN transceivers.

What analog peripherals are integrated into the R5F56604FGFP#10?

The R5F56604FGFP#10 integrates a 12-bit S12ADH A/D converter with 24 input channels (0.9 µs conversion time), two 12-bit R12DAb D/A outputs (0–AVCC0), four-channel CMPC analog comparators, and an on-die temperature sensor (±1.0°C accuracy). These peripherals support sensor signal conditioning, closed-loop control, and self-diagnostic functions required for IEC60730 certification.

What power supply and temperature specifications apply to the R5F56604FGFP#10?

The R5F56604FGFP#10 operates from a single 2.7–5.5 V VCC supply and 3.0–5.5 V AVCC0 analog supply, enabling direct 5-V system integration. It is rated for the G-version industrial temperature range of –40°C to +105°C and supports four low-power modes-including deep software standby with RTC active and SRAM retention-achieving sub-10 µA current draw.

How does the Event Link Controller (ELC) enhance real-time performance in the R5F56604FGFP#10?

The ELC in the R5F56604FGFP#10 enables 83 internal event signals-including MTU overflows, A/D completion, and timer matches-to directly trigger peripheral actions without CPU intervention or interrupt latency. For example, an MTU3a compare match can autonomously start an A/D conversion and chain to a DMACA transfer-reducing ISR overhead and guaranteeing sub-microsecond timing determinism in time-critical control loops.
