Renesas R5F56609CDFN#10

Overview

R5F56609CDFN#10 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and 32 Kbytes data flash. It integrates CAN FD (ISO 11898-1:2015), 12-bit A/D and D/A converters, RTC with sub-clock support, and hardware-accelerated trigonometric functions (TFU), targeting industrial motor control and IEC60730-compliant safety systems.

For engineers reviewing the R5F56609CDFN#10 datasheet, R5F56609CDFN#10 pinout, R5F56609CDFN#10 application, or R5F56609CDFN#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interface, 2.7–5.5 V single-supply operation, deep software standby mode with RTC persistence, and integrated memory protection unit (MPU) for functional safety designs.

Technical Context

The R5F56609CDFN#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching. Its clock system supports independent domain scaling: ICLK up to 120 MHz, PCLKA up to 120 MHz (for MTU3a/RSPI/SCI10–11), PCLKB up to 60 MHz (for TMRb/CMT/CMTW), and ADCLK up to 60 MHz for the S12ADH A/D converter.

Peripheral integration includes an Event Link Controller (ELC) enabling 83 internal event signals to trigger module operations without CPU intervention, and a Trusted Memory (TM) function that restricts instruction fetches from protected code flash regions-critical for secure boot and firmware integrity in industrial applications.

FAQ

What is the maximum operating frequency of the R5F56609CDFN#10 and how is it achieved?

The R5F56609CDFN#10 achieves a maximum operating frequency of 120 MHz via its RXv3 CPU core clocked by the PLL, which uses either the 8–24 MHz main crystal oscillator or the internal high-speed on-chip oscillator (HOCO) as a reference. The PLL multiplies the input frequency to generate the 120 MHz ICLK system clock, with no wait states for code flash or SRAM access-enabling deterministic real-time execution critical for motor control and safety applications.

Does the R5F56609CDFN#10 support CAN FD, and what standards does it comply with?

Yes, the R5F56609CDFN#10 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B networks-making it suitable for automotive body electronics and industrial gateways requiring high-bandwidth diagnostics and firmware updates.

What debugging interfaces are available on the R5F56609CDFN#10?

The R5F56609CDFN#10 supports both JTAG and FINE (single-wire) debugging interfaces. JTAG provides full boundary-scan capability, flash programming, and real-time trace via standard debug probes, while FINE enables minimal-pin debugging for space-constrained designs. Both interfaces are active simultaneously and support breakpoints, watchpoints, and memory inspection during development and field diagnostics of the R5F56609CDFN#10.

How does the R5F56609CDFN#10 support IEC60730 Class B compliance?

The R5F56609CDFN#10 integrates multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDTa) with windowing, RAM test-assisting function (DOC), CRC calculator (CRCA), and register write protection. These features enable automated self-tests and fault detection without software overhead-allowing developers to meet certification requirements for household appliances and industrial controllers using the R5F56609CDFN#10.

What is the role of the Event Link Controller (ELC) in the R5F56609CDFN#10?

The Event Link Controller (ELC) in the R5F56609CDFN#10 enables 83 internal peripheral events-such as timer overflows, ADC completions, or CAN message receptions-to directly trigger actions in other modules without CPU intervention. For example, an MTU3a timer match event can automatically start an S12ADH conversion, or a CAN FD reception can trigger a DMA transfer-reducing interrupt latency, lowering CPU load, and improving real-time determinism in applications like motor control or sensor fusion using the R5F56609CDFN#10.
