For engineers reviewing the R5F56609BGFP#10 datasheet, R5F56609BGFP#10 pinout, R5F56609BGFP#10 application, or R5F56609BGFP#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, dual D/A output capability, integrated ELC for event-driven low-power operation, and full CAN FD compliance per ISO 11898-1:2015 - critical for automotive body electronics and industrial fieldbus gateways.

Technical Context

The R5F56609BGFP#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 integrates main (8–24 MHz), sub (32.768 kHz), and on-chip oscillators (HOCO/LOCO), with PLL enabling 120 MHz ICLK and independent peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz).

It supports four low-power modes including deep software standby with RTC active, leverages ELC for interrupt-free inter-module triggering (e.g., MTU3a → S12ADH), and includes hardware safety features: MPU, Trusted Memory (TM), CRC calculator (CRCA), CAC, and register write protection - all aligned with IEC 60730 Class B requirements.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609BGFP#10?

The R5F56609BGFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under those conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 16-register bank architecture, and integrated 32-bit multiplier/divider. The R5F56609BGFP#10 sustains this speed with zero-wait-state access to both 1 MB code flash and 128 KB SRAM, enabling deterministic real-time response in motor control and metering applications.

Does the R5F56609BGFP#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56609BGFP#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps. It includes dedicated message RAM, flexible filtering, and error counters - essential for automotive body networks and industrial fieldbus gateways. Unlike basic CAN controllers, the R5F56609BGFP#10's CAN FD implementation handles FD frame arbitration and payload length extension natively in hardware, reducing CPU load during high-throughput communication.

What are the analog capabilities of the R5F56609BGFP#10, particularly regarding ADC and DAC?

The R5F56609BGFP#10 includes a 24-channel 12-bit S12ADH ADC with 0.9 µs minimum conversion time at 60 MHz ADCLK, plus two independent 12-bit R12DAb DAC channels with 0–AVCC0 output range. Each DAC output can serve as a reference voltage for the four-channel CMPC analog comparators. These resources enable closed-loop analog control, precision sensor conditioning, and self-test functionality - all verified for IEC 60730 Class B compliance in the R5F56609BGFP#10's safety documentation.

How does the Event Link Controller (ELC) enhance low-power operation in the R5F56609BGFP#10?

The ELC in the R5F56609BGFP#10 allows 83 internal peripheral events (e.g., MTU3a compare match, TMRb overflow, or SCI receive complete) to trigger actions in other modules - such as starting an ADC conversion or toggling a GPIO - without waking the CPU or consuming interrupt bandwidth. This enables the R5F56609BGFP#10 to remain in deep software standby while maintaining responsive, deterministic timing for time-critical analog or communication tasks, significantly extending battery life in portable or energy-harvesting systems.

Is the R5F56609BGFP#10 qualified for extended temperature operation, and what is its grade?

Yes, the R5F56609BGFP#10 is rated for –40°C to +105°C operation and carries the 'G' suffix denoting industrial/automotive temperature grade. This rating is validated across all embedded peripherals - including the 12-bit ADC, DAC, RTC (with sub-clock oscillator), and CAN FD transceiver - ensuring reliable performance in engine compartments, outdoor metering enclosures, and factory-floor controllers. The R5F56609BGFP#10's thermal design includes on-die temperature sensor with ±1.0°C relative precision, calibrated via the integrated 12-bit ADC.
