Product details
Overview
R5F566NNHDFC#30 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 gateways, and real-time control systems requiring deterministic timing, functional safety support (IEC60730), and rich peripheral integration.
For engineers reviewing the R5F566NNHDFC#30 datasheet, R5F566NNHDFC#30 pinout, R5F566NNHDFC#30 application, or R5F566NNHDFC#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-C (176-pin LQFP), validated pin functions, real-world use cases in industrial automation and embedded vision, and two confirmed alternative MCUs with documented technical and application differences.
Technical Context
The R5F566NNHDFC#30 implements the RXv3 CPU core with 698 CoreMark at 120 MHz, supporting little-endian data and single/double-precision IEEE-754 floating-point arithmetic. Its memory subsystem includes dual-bank 4-MB flash enabling background programming and bank-swapping, plus 1-MB SRAM with 32-KB ECC-protected region for safety-critical data storage.
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 graphics pipeline (GLCDC + DRW2D). Clocking uses PLL-based system clock up to 120 MHz, with independent PCLKA/PCLKB domains (120 MHz / 60 MHz) governing high-speed peripherals and analog modules respectively.

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 |
|---|---|---|---|
| R5F566NNDHFC#30 | Same RX66N group, identical 176-pin PLQP0176KB-C package, but 2-MB flash (vs. 4-MB) and no TSIP option | Suitable for cost-sensitive HMI where firmware size < 2 MB and cryptographic acceleration not required | Select when flash capacity and security features are non-critical; pinout and peripheral set otherwise match R5F566NNHDFC#30 |
| R5F566TNDHFC#30 | Same package and flash size, but RX66T subgroup-optimized for motor control with enhanced PWM (GPT3), no Ethernet MAC or GLCDC | Targeted at servo/inverter drives needing high-resolution PWM and encoder interfaces, not networking or graphics | Choose only for motor-control-centric designs; lacks Ethernet, SDHI, and graphics engines present in R5F566NNHDFC#30 |
Compared with R5F566NNHDFC#30, R5F566NNDHFC#30 reduces BOM cost by omitting 2 MB of flash and TSIP, while R5F566TNDHFC#30 trades networking/graphics capability for superior motor-control peripherals-neither is pin-compatible nor functionally interchangeable without hardware and firmware redesign.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F566NNHDFC#30?
The R5F566NNHDFC#30 operates at a maximum frequency of 120 MHz and achieves 698 CoreMark in benchmark testing at that speed. This performance stems from the RXv3 CPU core's efficient instruction set, dual-issue capability for certain operations, and zero-wait-state access to 4-MB flash and 1-MB SRAM-enabling deterministic real-time response in demanding industrial applications.
Does the R5F566NNHDFC#30 include hardware encryption support?
The R5F566NNHDFC#30 supports optional Trusted Secure IP (TSIP) and AES encryption with key lengths of 128, 192, and 256 bits. TSIP provides secure key storage, random number generation, and accelerated cryptographic operations-critical for secure boot, firmware authentication, and encrypted data logging in industrial gateways and smart meters.
What package type and pin count does the R5F566NNHDFC#30 use?
The R5F566NNHDFC#30 is housed in the PLQP0176KB-C package: a 176-pin Low-profile Quad Flat Package with 24 × 24 mm body size, 0.5-mm lead pitch, and exposed thermal pad. This LQFP variant supports high I/O density (136 general-purpose pins) while maintaining compatibility with standard PCB assembly processes.
How many CAN channels and mailboxes does the R5F566NNHDFC#30 support?
The R5F566NNHDFC#30 integrates three independent CAN modules compliant with ISO11898-1, each supporting 32 message mailboxes. This allows concurrent handling of multiple CAN networks-for example, one for device diagnostics, one for motion control, and one for safety communication-without software arbitration overhead.
Is the R5F566NNHDFC#30 suitable for IEC60730 Class B compliance?
Yes, the R5F566NNHDFC#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, CRC calculation accelerator (CRCA), independent watchdog timer (IWDTa) with window function, self-diagnostic routines for the A/D converter, and register write protection.
