Product details
Overview
R5F566NDDDFP#30 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz CPU, 4 MB on-chip code flash, 1 MB SRAM (including 32 KB ECC RAM), integrated Ethernet MAC, CAN, USB 2.0 FS, SDHI, QSPI, and GLCDC - designed for industrial HMI, networked gateway, and real-time control applications requiring deterministic timing and functional safety support.
For engineers reviewing the R5F566NDDDFP#30 datasheet, R5F566NDDDFP#30 pinout, R5F566NDDDFP#30 application, or R5F566NDDDFP#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-C (176-pin LQFP), validated pin functions, IEC60730-ready features, and two confirmed alternative MCUs with documented functional and packaging differences.
Technical Context
The R5F566NDDDFP#30 implements the RXv3 CPU core with double-precision IEEE-754 FPU, MPU, and collective register bank save - enabling deterministic real-time execution at 120 MHz (698 CoreMark). Its clock system integrates PLL, LOCO/HOCO oscillators, and independent IWDT-dedicated 120-kHz clock for fail-safe timing.
Peripheral architecture includes dual-bank flash supporting background programming, 32 KB data flash rated for 100,000 erase/write cycles, 8-channel DMACA, EXDMAC with cluster transfer, and ELC-driven event linking across 123 internal signals - eliminating CPU intervention for timer-triggered ADC starts, PWM dead-time compensation, or RTC time-capture on external events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566NEDDFP#30 | Same RX66N family, identical 176-pin LQFP package and 4 MB flash, but rated for –40°C to +105°C (G-grade) vs. D-grade (–40°C to +85°C) of R5F566NDDDFP#30. | Required for under-hood automotive or high-temp industrial enclosures where ambient exceeds 85°C. | Select R5F566NEDDFP#30 when extended temperature operation is mandatory; pinout and firmware are binary-compatible. |
| R5F566TDDDFP#30 | Same RX66N group, same package and temperature grade, but with 2 MB code flash (vs. 4 MB) and reduced peripheral set: no Ethernet MAC, no GLCDC, no DRW2D, only 1× CAN channel. | Suitable for cost-sensitive control nodes without display or network gateway functions - e.g., standalone motor controllers or sensor concentrators. | Choose R5F566TDDDFP#30 to reduce BOM cost by ~18% where Ethernet, graphics, and dual CAN are unnecessary. |

The R5F566NDDDFP#30 operates at a maximum frequency of 120 MHz and achieves 698 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with dual-issue capability, on-chip 32-bit multiplier/divider, and optimized pipeline - enabling real-time deterministic execution for industrial control loops and protocol stacks without external acceleration.
Does the R5F566NDDDFP#30 support Ethernet communication, and what PHY interfaces are available?
Yes, the R5F566NDDDFP#30 integrates a full-featured Ethernet MAC supporting 10/100 Mbps in full- and half-duplex modes. It provides MII and RMII interfaces for connection to external PHY devices, along with PMGI for IEEE 802.3u-compliant PHY management - enabling plug-and-play Ethernet connectivity without external MAC/PHY bridging logic.
What is the flash memory configuration of the R5F566NDDDFP#30, and does it support background programming?
The R5F566NDDDFP#30 includes 4 MB of on-chip code flash memory organized in a dual-bank structure, allowing background programming (BGO) - meaning code can execute from one bank while the other is being erased or programmed. This enables live firmware updates without halting application execution, critical for uptime-sensitive industrial systems.
How many CAN channels does the R5F566NDDDFP#30 support, and what protocol compliance is guaranteed?
The R5F566NDDDFP#30 supports three independent CAN channels, each compliant with ISO 11898-1 (Classical CAN) for both standard and extended frames. Each channel provides 32 dedicated mailboxes with configurable acceptance filtering, enabling robust multi-node vehicle or industrial network communication with deterministic latency and error handling.
Is the R5F566NDDDFP#30 qualified for functional safety standards such as IEC60730?
Yes, the R5F566NDDDFP#30 includes hardware features required for IEC60730 Class B compliance: oscillation-stoppage detection, CRC calculation unit (CRCA), independent watchdog timer (IWDT) with windowing, self-diagnostic A/D converter test, and register write protection.
