Product details
Overview
R5F566NNDDFB#10 from Renesas is a 120-MHz 32-bit RXv3 microcontroller with double-precision IEEE-754 FPU, 4-MB on-chip code flash (dual-bank), 1-MB SRAM (including 32-KB ECC RAM), 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 R5F566NNDDFB#10 datasheet, R5F566NNDDFB#10 pinout, R5F566NNDDFB#10 application, or R5F566NNDDFB#10 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-C (176-pin LQFP, 24 × 24 mm, 0.5-mm pitch), validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The R5F566NNDDFB#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 dual-bank 4-MB code flash enabling background programming and bank-swapping, plus 1-MB SRAM with 32-KB ECC-protected region for fault-tolerant execution.
Peripheral architecture integrates Ethernet MAC (10/100 Mbps, MII/RMII), three CAN channels (ISO11898-1, 32 mailboxes each), SDHI (25 MB/s), QSPI, and a full-featured graphics subsystem (GLCDC + DRW2D). Clocking uses PLL-based synthesis with independent PCLKA (up to 120 MHz) and PCLKB (up to 60 MHz) domains to optimize performance and power across modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566NNDHFB#10 | Same RX66N core, identical peripherals, but in PLQP0144KA-B (144-pin LQFP, 20 × 20 mm); 2-MB flash instead of 4-MB | Suitable for space-constrained designs where 2-MB flash suffices and smaller footprint is prioritized | Select when board layout requires reduced package size and firmware image fits within 2-MB limit |
| R5F566TNDHFB#10 | Same package and flash size, but G-version (–40°C to +105°C operating range); otherwise functionally identical | Required for under-hood automotive or high-temperature industrial enclosures exceeding 85°C ambient | Choose only when extended temperature rating is mandatory-no other functional trade-offs |
Compared with R5F566NNDDFB#10, the R5F566NNDHFB#10 reduces flash capacity and package size for compact cost-sensitive designs, while the R5F566TNDHFB#10 maintains full feature parity but extends thermal operation to +105°C-making it the sole drop-in replacement for high-temperature deployment.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F566NNDDFB#10?
The R5F566NNDDFB#10 operates at a maximum frequency of 120 MHz and achieves 698 CoreMark in benchmark testing. This performance stems from the RXv3 CPU core's optimized pipeline, double-precision FPU, and zero-wait-state access to 4-MB code flash and 1-MB SRAM-enabling deterministic real-time execution in demanding industrial applications.
Does the R5F566NNDDFB#10 support functional safety standards like IEC60730?
Yes, the R5F566NNDDFB#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, CRC-A accelerator, independent watchdog timer (IWDTa), self-diagnostic A/D converter, and register write protection. These are documented in Renesas Application Note R01AN4223JJ0100 and validated in the RX66N Safety Manual.
What package type and pin count does the R5F566NNDDFB#10 use?
The R5F566NNDDFB#10 uses the PLQP0176KB-C package: a 176-pin LQFP with 24 × 24 mm body size, 0.5-mm lead pitch, and exposed thermal pad. This package supports the full I/O count (136 general-purpose pins) and thermal dissipation needed for sustained 120-MHz operation in industrial environments.
Can the R5F566NNDDFB#10 execute firmware updates without interrupting real-time operation?
Yes, the R5F566NNDDFB#10 supports background programming (BGO) and dual-bank flash architecture. Firmware updates can be written to the inactive bank while the active bank continues executing code-enabling zero-downtime field upgrades. Bank switching occurs atomically at reset or via software trigger, preserving system continuity.
What graphics capabilities does the R5F566NNDDFB#10 provide for HMI applications?
The R5F566NNDDFB#10 integrates a Graphic-LCD Controller (GLCDC) supporting 3-plane overlay (background, graphic 1, graphic 2) and a 2D Drawing Engine (DRW2D) with vector drawing, bit blitting, and texture mapping. Together, they enable smooth 480×272@60 Hz UI rendering without external GPU-reducing latency and system complexity in industrial HMI designs.
