Renesas R5F566NNDGFB#30

Overview

R5F566NNDGFB#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, 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 with 195 ps HRPWM timing resolution. It integrates dual 12-bit ADC units with PGA support, CAN 2.0B, full-speed USB 2.0 host/function/OTG, and TSIP-Lite encryption for IEC 60730-compliant safety-critical systems.

For engineers reviewing the R5F566NNDGFB#30 datasheet, R5F566NNDGFB#30 pinout, R5F566NNDGFB#30 application, or R5F566NNDGFB#30 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across 30-channel 12-bit ADC, hardware-accelerated PWM dead-time management, event-driven peripheral coordination via ELC, and secure firmware update capability through on-chip data flash with background programming.

Technical Context

The R5F566NNDGFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. Its clock system supports PLL multiplication of 8–24 MHz crystal or 16/18/20 MHz HOCO reference, delivering independent PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), PCLKC (up to 160 MHz), and PCLKD (up to 60 MHz) domains for precise peripheral timing alignment.

Motor control is enabled by tightly coupled peripherals: ten 32-bit GPTW timers with synchronous start/stop and dead-time insertion, nine 16-bit MTU3d channels supporting 3-phase complementary PWM, six analog comparators, and four HRPWM channels synchronized to GPTW outputs for sub-nanosecond edge placement-critical for high-efficiency SiC/GaN inverter gate driving.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566NNDGFB#30?

The R5F566NNDGFB#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance under benchmark conditions. This reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and on-chip cache behavior-enabling real-time motor control loops with sub-microsecond jitter. The R5F566NNDGFB#30 sustains this performance across its full temperature range (–40°C to +105°C) with no derating required.

Does the R5F566NNDGFB#30 support simultaneous sampling across all 30 ADC channels?

No-the R5F566NNDGFB#30 supports simultaneous sampling only within each of its three S12ADH units: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels, no sample-and-hold). True simultaneous sampling across all 30 channels is not possible; however, inter-unit synchronization via ELC allows near-simultaneous triggering with <100 ns skew between units-sufficient for most FOC implementations.

What PWM resolution does the R5F566NNDGFB#30 achieve with its HRPWM feature?

The R5F566NNDGFB#30 achieves a minimum PWM edge placement resolution of 195 ps when operating its HRPWM channels at 160 MHz. This resolution applies specifically to the four HRPWM outputs synchronized to GPTW0–GPTW3 timers and enables precise dead-time control and phase-shift accuracy critical for SiC/GaN-based inverters. Standard GPTW PWM resolution remains at 6.25 ns (160 MHz clock period).

Is the R5F566NNDGFB#30 qualified for automotive applications?

The R5F566NNDGFB#30 is rated for industrial temperature range (–40°C to +105°C) and meets IEC 60730 Class B requirements, but it is not AEC-Q100 qualified and lacks automotive-specific features such as extended voltage range (4.5–5.5 V), enhanced ESD immunity (>2 kV HBM), or ASIL-certified safety documentation. For automotive traction or charging applications, Renesas recommends the RX72T or RH850/F1K families instead of the R5F566NNDGFB#30.

How many CAN mailboxes does the R5F566NNDGFB#30 support, and are they configurable?

The R5F566NNDGFB#30 supports 32 dedicated CAN mailboxes in its single CAN module (CAN0), compliant with ISO 11898-1 for standard and extended frames. Each mailbox is fully configurable for transmit/receive mode, message ID filtering (standard or extended), acceptance mask, and priority level. Mailbox allocation is software-defined at initialization-no fixed hardware partitioning-and supports mixed TX/RX usage across all 32 slots.
