Renesas R5F566NNDGFP#30

Overview

R5F566NNDGFP#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for real-time motor control in industrial inverters and servo drives, operating at up to 160 MHz with 928 CoreMark performance, 1 MB on-chip code flash, 128 KB SRAM (no wait states), and integrated 3-phase/5-phase complementary PWM generation across 10 GPTW channels.

For engineers reviewing the R5F566NNDGFP#30 datasheet, R5F566NNDGFP#30 pinout, R5F566NNDGFP#30 application, or R5F566NNDGFP#30 equivalent, key selection considerations include its 144-pin LFQFP package with 110 GPIOs (4 × 5-V tolerant), 12-bit S12ADH ADC with simultaneous sampling across three units (30 channels total), HRPWM with 195 ps timing resolution, and ISO 11898-1 CAN interface with 32 mailboxes - all supporting IEC 60730 Class B compliance.

Technical Context

The R5F566NNDGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and configurable endian mode. Its clock system integrates PLL with selectable reference sources (8–24 MHz crystal or 16/18/20 MHz HOCO), enabling independent scaling of ICLK (up to 160 MHz), PCLKA (120 MHz), PCLKB (60 MHz), and PCLKC (160 MHz) for peripheral domains.

Real-time motor control is enabled by tightly coupled peripherals: GPTW timers synchronized to PCLKC for high-precision PWM, ELC for interrupt-free inter-module triggering (e.g., MTU3 start → A/D conversion), and POE3B/POEG for hardware fault-driven waveform output disable during overcurrent or short-circuit events - all operating without CPU intervention in sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566NNDGFP#30?

The R5F566NNDGFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem - enabling deterministic execution of complex motor control algorithms in real time without pipeline stalls.

Does the R5F566NNDGFP#30 support IEC 60730 Class B functional safety requirements?

Yes, the R5F566NNDGFP#30 includes dedicated hardware for IEC 60730 compliance: clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, oscillation-stop detection, and register write protection. These features reduce external safety component count and simplify certification for industrial motor control applications.

What package type and pin count does the R5F566NNDGFP#30 use?

The R5F566NNDGFP#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with 20 × 20 mm body and 0.5 mm pitch (PLQP0144KA-B). It provides 110 general-purpose I/O pins, including 4 × 5-V tolerant inputs, essential for interfacing with industrial-level sensors and actuators without level-shifting circuitry.

How many channels of 12-bit ADC does the R5F566NNDGFP#30 integrate, and what is its sampling capability?

The R5F566NNDGFP#30 integrates a total of 30 channels across three 12-bit S12ADH ADC units, with simultaneous sampling supported across all units. Each unit includes dedicated sample-and-hold circuits (3 per unit for Units 0 and 1), enabling precise, time-aligned current and voltage measurements critical for field-oriented motor control.

What communication interfaces are available on the R5F566NNDGFP#30 for industrial networking?

The R5F566NNDGFP#30 provides CAN (ISO 11898-1, 32 mailboxes), USB 2.0 full-speed host/function/OTG, seven SCI channels (including LIN-capable SCI12), one I2C (RIICa, 400 kbps), and one RSPI (30 Mbps). This combination supports robust industrial networking, firmware updates, and multi-protocol gateway functionality without external bridge ICs.
