Renesas R5F56609EGFP#30

Overview

R5F56609EGFP#30 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 motor control, building automation gateways, and IEC60730-compliant appliance controllers.

For engineers reviewing the R5F56609EGFP#30 datasheet, R5F56609EGFP#30 pinout, R5F56609EGFP#30 application, or R5F56609EGFP#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), dual D/A output capability, sub-clock oscillator support for RTC, and JTAG/FINE debug interface availability.

Technical Context

The R5F56609EGFP#30 implements the RXv3 CPU core with single-precision FPU, 113 instructions including DSP and floating-point operations, and collective register bank save for fast context switching. It integrates an MPU for memory protection and Trusted Memory (TM) for secure code execution in the flash target area.

Clock architecture includes main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and fine-grained peripheral clock domain control (ICLK up to 120 MHz, PCLKA/B/D at up to 120/60/60 MHz). Real-time clock operation requires sub-clock oscillator support - confirmed present in this 144-pin variant.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609EGFP#30?

The R5F56609EGFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from the RXv3 CPU core's optimized pipeline, single-cycle instruction execution, and integrated 32-bit multiplier/divider - enabling efficient real-time control algorithms and floating-point computation without external acceleration. The R5F56609EGFP#30 sustains full-speed operation across its entire industrial temperature range.

Does the R5F56609EGFP#30 support real-time clock (RTC) functionality, and what is required to enable it?

Yes, the R5F56609EGFP#30 supports RTC functionality, but it requires connection of a 32.768 kHz crystal to the RTCXTAL/RTCXTAL pins. As a 144-pin LFQFP variant with sub-clock oscillator support, the R5F56609EGFP#30 can operate RTC in both binary counting and calendar modes, with alarm, periodic, and carry interrupts. The RTC remains active in deep software standby mode - a key feature for energy-sensitive applications using the R5F56609EGFP#30.

What debugging interfaces are available on the R5F56609EGFP#30, and how do they differ?

The R5F56609EGFP#30 provides both JTAG and FINE (single-wire) debugging interfaces. JTAG supports full boundary-scan, real-time trace, and high-speed flash programming - ideal for development and production test. FINE uses a single pin for debugging and programming, reducing PCB footprint and pin count - suitable for space-constrained designs. Both interfaces are fully supported by Renesas' e2 studio and CS+ toolchains for the R5F56609EGFP#30.

How many CAN FD channels does the R5F56609EGFP#30 integrate, and what standards does it comply with?

The R5F56609EGFP#30 integrates one CAN FD channel 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. The CAN FD module includes dedicated message RAM, error counters, and loopback self-test - essential for robust fieldbus communication in industrial and automotive applications using the R5F56609EGFP#30.

What is the flash memory configuration of the R5F56609EGFP#30, and does it support background programming?

The R5F56609EGFP#30 includes 1 Mbyte of on-chip code flash memory with no-wait-state access at 120 MHz, plus 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. Both memory types support background programming and erasing (BGO), allowing the CPU to execute application code while flash operations proceed - critical for over-the-air updates and runtime data logging in systems built around the R5F56609EGFP#30.
