Product details
Overview
R5F566TKCDFB#10 from Renesas is a 120-MHz 32-bit RXv3 microcontroller with double-precision IEEE-754 FPU, 2 MB on-chip code flash, 1 MB SRAM (512 KB + 512 KB expansion), and integrated Ethernet MAC, CAN, SDHI, QSPI, and GLCDC. It targets industrial HMI, networked gateway, and real-time control applications requiring deterministic timing, functional safety support (IEC60730), and rich peripheral integration.
For engineers reviewing the R5F566TKCDFB#10 datasheet, R5F566TKCDFB#10 pinout, R5F566TKCDFB#10 application, or R5F566TKCDFB#10 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-C), dual-bank flash for safe firmware updates, 32 KB data flash rated for 100,000 erase/write cycles, and hardware-accelerated 2D graphics (DRW2D) with GLCDC for embedded display systems.
Technical Context
The R5F566TKCDFB#10 implements the RXv3 CPU core with 698 CoreMark at 120 MHz, supporting little-endian or big-endian data arrangement and 113 instructions including DSP and floating-point operations. Its memory subsystem includes 2 MB code flash with 8.3 ns read cycle at full speed, 1 MB SRAM (no wait states), and 32 KB ECC RAM with SEC-DED error correction.
Peripheral architecture features dedicated clock domains: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, GLCDC, DRW2D), and PCLKB up to 60 MHz for timers and ADCs. It integrates three CAN channels (ISO11898-1 compliant, 32 mailboxes each), Ethernet MAC with MII/RMII, and a parallel data capture unit (PDC) - though PDC is excluded in 100-pin variants, it is confirmed active in this 176-pin configuration.

What is the maximum operating frequency and CoreMark score of the R5F566TKCDFB#10?
The R5F566TKCDFB#10 operates at a maximum frequency of 120 MHz and achieves 698 CoreMark under benchmark conditions. This performance stems from the RXv3 CPU core's efficient instruction pipeline, dual-issue capability for certain operations, and zero-wait-state access to 2 MB on-chip flash and 1 MB SRAM - enabling deterministic real-time execution critical for industrial control loops.
Does the R5F566TKCDFB#10 support dual-bank flash for safe firmware updates?
Yes, the R5F566TKCDFB#10 supports dual-bank flash architecture, allowing background programming of one bank while executing code from the other. This enables seamless over-the-air (OTA) firmware updates without halting application execution - a key requirement for uptime-critical industrial gateways and medical devices using the R5F566TKCDFB#10.
Which display interfaces are integrated into the R5F566TKCDFB#10?
The R5F566TKCDFB#10 integrates a Graphic-LCD Controller (GLCDC) supporting 24-bit RGB parallel output with HSYNC/VSYNC/DE signals, and a 2D Drawing Engine (DRW2D) for hardware-accelerated vector and bitmap operations. Together, they drive TFT panels up to WXGA resolution and offload UI rendering from the RXv3 CPU - essential for responsive HMI designs built around the R5F566TKCDFB#10.
Can the R5F566TKCDFB#10 interface directly with an external CAN transceiver?
Yes, the R5F566TKCDFB#10 includes three fully compliant ISO11898-1 CAN controllers, each with 32 message mailboxes and programmable bit timing. Its CRX0/CTX0 and related pins provide direct differential signaling to standard CAN transceivers (e.g., TJA1042, SN65HVD230), enabling robust 1 Mbps fieldbus communication in automotive and industrial networks using the R5F566TKCDFB#10.
What safety certifications or features does the R5F566TKCDFB#10 support for IEC60730 compliance?
The R5F566TKCDFB#10 includes hardware features required for Class B IEC60730 compliance: oscillation-stop detection, CRC accelerator (CRCA), independent watchdog timer (IWDT) with window function, A/D converter self-diagnostic mode, and register write protection.
