Product details
Overview
R5F566NDDDBG#20 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 R5F566NDDDBG#20 datasheet, R5F566NDDDBG#20 pinout, R5F566NDDDBG#20 application, or R5F566NDDDBG#20 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-C (176-pin LFBGA), validated pin functions, real-world use cases, and two confirmed alternative MCUs - all grounded in Renesas' official R01DS0344EJ0120 Rev.1.20 documentation.
Technical Context
The R5F566NDDDBG#20 implements the RXv3 CPU core with 698 CoreMark at 120 MHz, supporting little-endian or big-endian data, 113 instructions including DSP and floating-point ops, and collective register bank save across 16 banks. Its memory subsystem includes dual-bank 4-MB flash (8.3-ns access at 120 MHz), 512-KB main SRAM, 512-KB expansion RAM, and 32-KB ECC RAM with SEC-DED error correction.
Peripherals are clocked via independent domains: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for ETHERC/DRW2D/GLCDC, PCLKB up to 60 MHz for timers/A/D converters, and BCLK up to 80 MHz for external bus. It integrates three CAN channels (ISO11898-1, 32 mailboxes each), one Ethernet MAC with RMII/MII, and hardware-accelerated DRW2D graphics engine with vector drawing and bit blitting.

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 |
|---|---|---|---|
| R5F566NEDDBG#20 | Same RX66N family, identical 176-pin LFBGA (PLQP0176KB-C), but with 2-MB code flash instead of 4-MB; same peripherals, clocking, and ECC RAM. | Suitable where firmware size < 2 MB and cost sensitivity outweighs future scalability needs. | Select R5F566NEDDBG#20 only if application binary fits within 2-MB flash and no dual-bank update requirement exists. |
| R5F566TDDDBG#20 | Same package and flash size, but belongs to RX66T group - optimized for motor control with enhanced MTU3a PWM resolution, 3-phase complementary outputs, and faster current-sampling ADC triggers. | Better suited for servo/inverter drives; lacks GLCDC, DRW2D, SDHI, and Ethernet MAC present in R5F566NDDDBG#20. | Choose R5F566TDDDBG#20 only when motor control performance dominates over HMI/networking requirements. |
Compared with R5F566NDDDBG#20, the R5F566NEDDBG#20 reduces flash capacity by half but retains identical peripheral set and safety features - ideal for cost-constrained deployments without field-upgrade needs. The R5F566TDDDBG#20 trades networking and graphics capability for higher-resolution PWM and motor-specific timing - making it unsuitable for gateway or display-centric designs.

What package type and pin count does the R5F566NDDDBG#20 use?
The R5F566NDDDBG#20 uses the PLQP0176KB-C package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5-mm ball pitch. It is rated for –40°C to +85°C operation (D-version) and includes an exposed thermal pad for thermal management in high-throughput applications.
Which communication interfaces are integrated into the R5F566NDDDBG#20?
The R5F566NDDDBG#20 integrates Ethernet MAC (10/100 Mbps, MII/RMII), three CAN 2.0B channels (ISO11898-1), 13 serial channels (SCIj/i/h), three I²C interfaces (up to 1 Mbps), one QSPI, one SD host interface (SDHI), and one MMCIF. These interfaces support simultaneous wired connectivity for industrial protocols, human-machine interaction, and data storage.
Is the R5F566NDDDBG#20 qualified for functional safety standards like IEC60730?
Yes, the R5F566NDDDBG#20 includes multiple hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, CRC-A accelerator, windowed independent watchdog timer (IWDTa), A/D converter self-diagnostic, and register write protection.
