Product details
Overview
R5F56609EDFB#10 from Renesas is a 32-bit RXv3 core MCU operating at up to 120 MHz, featuring 1 Mbyte on-chip code flash, 128 Kbytes SRAM, 32 Kbytes data flash, CAN FD interface, 12-bit A/D and D/A converters, RTC with sub-clock oscillator support, and 134 general-purpose I/O pins in a 144-pin LFQFP package - deployed in industrial motor control, building automation gateways, and safety-compliant embedded systems.
For engineers reviewing the R5F56609EDFB#10 datasheet, R5F56609EDFB#10 pinout, R5F56609EDFB#10 application, or R5F56609EDFB#10 equivalent, this page delivers verified specifications, validated pin functions, confirmed low-power modes (deep software standby with RTC active), exact peripheral channel counts per package, and real-world IEC60730 compliance features including oscillation-stop detection and RAM test-assisting DOCA.
Technical Context
The R5F56609EDFB#10 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, supporting 709 CoreMark at 120 MHz and collective register bank save across 16 banks. It integrates an MPU for eight configurable memory protection regions and Trusted Memory (TM) to restrict code flash access to CPU instruction fetch only.
Its clock system combines a 8–24 MHz main crystal oscillator (PLL-referenced), 32.768 kHz sub-clock oscillator, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocks: ICLK up to 120 MHz, PCLKA up to 120 MHz (for MTU/RSPI/SCI10–11), PCLKB up to 60 MHz (for TMR/CMT/CMTW), and ADCLK up to 60 MHz for S12ADH.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F56608ADFP#30 | Same RX660 Group, 100-pin LFQFP, 512 Kbyte code flash, 1-channel D/A, no sub-clock oscillator (RTC disabled) | Limited to non-RTC applications; fewer I/O (88 pins) and reduced SCI count (10 channels vs. 13) | Select when board space is constrained and RTC/calendar functions are unnecessary. |
| R5F566T9ADFP#30 | RX66T variant: identical package/pinout but adds 3-phase motor control accelerators (IPM, encoder interface) and higher-temp grade (–40°C to +105°C) | Optimized for inverter drives; includes hardware IPM fault handling and quadrature encoder inputs not present in R5F56609EDFB#10 | Choose for new motor drive designs requiring integrated motion control logic and extended thermal range. |
Compared with R5F56609EDFB#10, the R5F56608ADFP#30 reduces cost and footprint but sacrifices RTC, second DAC channel, and 34 I/O pins; the R5F566T9ADFP#30 retains full pin compatibility while adding motor-specific hardware - making it a functional upgrade path rather than a drop-in replacement.

FAQ
What is the maximum operating frequency and core architecture of the R5F56609EDFB#10?
The R5F56609EDFB#10 features a 32-bit RXv3 CPU core with integrated single-precision FPU, operating at a maximum frequency of 120 MHz. It achieves 709 CoreMark score under benchmark conditions and supports collective register bank save across 16 banks. The core implements IEEE 754-compliant floating-point arithmetic and executes instructions in one system clock cycle for deterministic real-time behavior.
Does the R5F56609EDFB#10 support real-time clock (RTC) functionality, and what are the requirements?
Yes, the R5F56609EDFB#10 supports RTC functionality via its RTCC module, but requires connection of a 32.768 kHz crystal to XT1/XT2 pins. The device includes calendar/time capture modes, leap-year adjustment, and alarm/periodic interrupts. RTC remains operational in deep software standby mode. Devices without sub-clock oscillator capability (e.g., certain 100-pin variants) cannot use RTC - but R5F56609EDFB#10 is a 144-pin variant with full sub-clock support.
What safety certifications and built-in diagnostics does the R5F56609EDFB#10 provide for IEC60730 compliance?
The R5F56609EDFB#10 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stoppage detection for main/sub-clock, clock frequency accuracy measurement circuit (CAC), RAM test-assisting function via DOCA, CRCA for 8/32-bit CRC, independent watchdog timer (IWDTa) with window function, and register write protection. These are documented in the R01DS0393EJ0100 datasheet and require no external components to implement basic safety monitoring.
How many communication interfaces does the R5F56609EDFB#10 include, and which are CAN FD-capable?
The R5F56609EDFB#10 includes 1 CAN FD channel compliant with ISO 11898-1:2015 (supporting both standard and extended frames), 13 SCI channels (SCIk/SCIm/SCIh), 2 RIIC interfaces (I²C/SMBus up to 400 kbps), 1 RSPId (SPI up to 30 Mbps), and 1 REMCa remote control signal receiver. Only the dedicated CANFD module supports CAN FD protocol - SCI and RSPI operate as conventional UART/SPI peripherals and do not provide CAN physical layer or protocol handling.
What are the memory resources and programming capabilities of the R5F56609EDFB#10?
The R5F56609EDFB#10 integrates 1 Mbyte of on-chip code flash memory with no-wait access at 120 MHz, 32 Kbytes of reprogrammable data flash (rated for 100,000 erase/write cycles), and 128 Kbytes of SRAM with zero wait states. Programming is supported via on-board methods (SCI/FINE) or off-board parallel programming. Trusted Memory (TM) enables secure code protection by restricting flash access to CPU instruction fetch only.
