Overview

R5F56604BDFP#10 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz maximum operating frequency, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and remote control signal receiver - deployed in industrial HMI, motor control, and smart sensor edge nodes requiring deterministic real-time response and IEC 60730 compliance.

For engineers reviewing the R5F56604BDFP#10 datasheet, R5F56604BDFP#10 pinout, R5F56604BDFP#10 application, or R5F56604BDFP#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug support, sub-clock oscillator inclusion, full 24-channel S12ADH ADC, dual-channel R12DAb DAC, and verified CAN FD compliance per ISO 11898-1:2015.

Technical Context

The R5F56604BDFP#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 integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division paths for ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), and ADCLK (60 MHz).

Peripheral coordination is managed via the Event Link Controller (ELC), enabling 83 internal event signals to trigger module operations-including MTU3a PWM generation, S12ADH conversion starts, and IWDT refresh-without CPU intervention, even during deep software standby mode where RTC continues running.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604BDFP#10?

The R5F56604BDFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and optimized pipeline - enabling deterministic real-time response in motor control and industrial PLC applications where R5F56604BDFP#10 is deployed.

Does the R5F56604BDFP#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604BDFP#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. The module includes message filtering, TX/RX buffering, and error handling - making R5F56604BDFP#10 suitable for automotive body networks and industrial fieldbus gateways requiring higher bandwidth than classical CAN.

What analog peripherals are included in the R5F56604BDFP#10, and how are they used together?

The R5F56604BDFP#10 includes a 24-channel 12-bit S12ADH ADC, two 12-bit R12DAb DACs, four CMPC analog comparators, and an on-die temperature sensor. The DAC outputs can serve as precise reference voltages for the comparators, enabling configurable overvoltage/undervoltage detection - a configuration directly supported in R5F56604BDFP#10's hardware and used in power supply monitoring and motor phase protection circuits.

Is the R5F56604BDFP#10 qualified for industrial temperature range, and what is its operating voltage range?

Yes, the R5F56604BDFP#10 is rated for the industrial temperature range of –40°C to +85°C (D-version) and operates from a single 2.7 V to 5.5 V supply. Its AVCC0 analog rail requires 3.0–5.5 V and must be ≥ VCC - a constraint critical for stable ADC/DAC operation and explicitly defined in the R5F56604BDFP#10 datasheet for reliable sensor interface design.

What debugging interfaces does the R5F56604BDFP#10 support, and are both available in this package variant?

The R5F56604BDFP#10 supports both JTAG and FINE (one-line) debugging interfaces, and both are enabled in its 144-pin LFQFP (PLQP0144KA-B) package. This dual-interface capability allows flexible development - JTAG for full-featured debug and trace, FINE for minimal pin-count in-space programming - confirmed for R5F56604BDFP#10 in Renesas documentation R01DS0393EJ0100.
