Renesas R5F566NDHGBG#20

Overview

R5F566NDHGBG#20 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 timers (GPTW/MTU3) with 195 ps HRPWM resolution. It integrates CAN, USB 2.0 FS host/function, 12-bit A/D converter with 30 channels and programmable gain amplifiers, and TSIP-Lite encryption for IEC60730-compliant safety-critical systems.

For engineers reviewing the R5F566NDHGBG#20 datasheet, R5F566NDHGBG#20 pinout, R5F566NDHGBG#20 application, or R5F566NDHGBG#20 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across three 12-bit ADC units, hardware-accelerated PWM dead-time compensation, event-linked peripheral coordination (ELC), and robust functional safety features including oscillation-stop detection, RAM ECC, and independent watchdog timer.

Technical Context

The R5F566NDHGBG#20 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian support. Its clock system combines PLL-synthesized 160 MHz ICLK with independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (160 MHz), and PCLKD (60 MHz) domains to optimize peripheral timing - critical for synchronized PWM generation, ADC sampling, and CAN/USB transaction scheduling.

Motor control execution relies on tightly coupled peripherals: GPTW (10-channel 32-bit PWM), MTU3d (9-channel 16-bit timer), HRPWM (4-channel 195 ps edge control), POE3B/POEG output enable logic, and ELC-driven trigger chaining - enabling zero-CPU-overhead waveform sequencing, phase-shifted A/D conversion starts, and fault-responsive pin disable without interrupt latency.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566NDHGBG#20?

The R5F566NDHGBG#20 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, single-cycle instruction execution, and optimized memory subsystem - enabling deterministic real-time motor control loops with sub-microsecond jitter. The R5F566NDHGBG#20 sustains this performance across its full temperature range (–40°C to +105°C) with no derating.

Does the R5F566NDHGBG#20 support simultaneous sampling across all 30 ADC channels?

No - the R5F566NDHGBG#20 supports simultaneous sampling across three independent 12-bit ADC units (S12ADH), totaling 30 channels: Unit 0 (8 ch), Unit 1 (8 ch), and Unit 2 (14 ch). While all units can be triggered concurrently via ELC or software, each unit samples its assigned channels in sequence. Simultaneous sampling applies per unit, not globally across all 30 channels. The R5F566NDHGBG#20 uses this architecture to capture synchronized current/voltage snapshots for multi-axis motor control.

What PWM resolution does the R5F566NDHGBG#20 achieve with its HRPWM feature?

The R5F566NDHGBG#20 achieves a minimum PWM edge resolution of 195 ps using its High-Resolution PWM (HRPWM) circuit, which operates on GPTW0–GPTW3 channels. This resolution is realized at 160 MHz system clock and enables precise dead-time adjustment, phase-shift control, and harmonic suppression in high-frequency inverter designs. The R5F566NDHGBG#20 maintains this specification across its full operating temperature range without calibration.

Is USB functionality included in the R5F566NDHGBG#20, and what modes does it support?

Yes, the R5F566NDHGBG#20 integrates a full-featured USB 2.0 Full-Speed host/function/OTG module (USBb) compliant with the USB 2.0 specification. It supports host mode (12 Mbps/1.5 Mbps), function mode (12 Mbps), and OTG operation (excluding low-speed). The R5F566NDHGBG#20 includes 2 KB on-chip RAM for transfer buffering and requires no external pull-up/pull-down resistors, simplifying board design for firmware updates and human-interface device connectivity.

How does the R5F566NDHGBG#20 support IEC60730 functional safety compliance?

The R5F566NDHGBG#20 includes multiple hardware features for IEC60730 Class B compliance: independent watchdog timer (IWDT) with windowing, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function (DOC), oscillation-stop detection, and register write protection. These features enable self-diagnostic routines without external components. The R5F566NDHGBG#20 also provides Trusted Memory (TM) protection for secure boot and TSIP-Lite encryption for firmware integrity - collectively meeting key requirements for safety-critical motor control applications.
