Renesas R5F566NDHGFB#30

Overview

R5F566NDHGFB#30 from Renesas is a 32-bit RXv3 core 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, and integrated high-resolution PWM (195 ps minimum resolution) for precise timing of 3-phase/5-phase complementary waveforms.

For engineers reviewing the R5F566NDHGFB#30 datasheet, R5F566NDHGFB#30 pinout, R5F566NDHGFB#30 application, or R5F566NDHGFB#30 equivalent, key selection criteria include its 144-pin LFQFP package with 110 general I/Os (4 × 5-V tolerant), dual 12-bit A/D converters supporting simultaneous sampling across 30 channels, integrated CAN 2.0B interface, full-speed USB 2.0 host/function capability, and TSIP-Lite encryption for IEC 60730-compliant safety-critical systems.

Technical Context

The R5F566NDHGFB#30 implements the RXv3 CPU core with single-precision FPU and IEEE 754 compliance, executing instructions at 160 MHz with no wait states on 128 KB SRAM and 1 MB flash (cache-enabled). Its clock system supports PLL multiplication using 8–24 MHz external crystals or internal 16–20 MHz HOCO, delivering independent peripheral clocks (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for GPTW, MTU3, and HRPWM modules.

Motor control functionality is anchored by three timer subsystems: 10-channel 32-bit GPTW with synchronous start/stop and dead-time generation; 9-channel 16-bit MTU3d supporting 3-phase complementary PWM; and 4-channel HRPWM enabling sub-nanosecond edge placement on GPTW outputs. All timers integrate ELC event linking for CPU-free coordination during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566NDHGFB#30?

The R5F566NDHGFB#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 real-time execution of complex motor control algorithms such as field-oriented control and predictive current regulation within tight timing budgets.

Does the R5F566NDHGFB#30 support simultaneous sampling across all 30 ADC channels?

No, the R5F566NDHGFB#30 supports simultaneous sampling only within each of its three independent 12-bit S12ADH units: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). While all 30 channels can be scanned in sequence, true simultaneous sampling is limited to the 3 sample-and-hold circuits per unit-enabling concurrent acquisition of up to 3 phase currents and DC-link voltage in motor control applications.

What safety certifications and features does the R5F566NDHGFB#30 include for IEC 60730 compliance?

The R5F566NDHGFB#30 includes multiple hardware-based safety features for IEC 60730 Class B compliance: oscillation-stop detection for main clock, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA) for memory integrity, data operation circuit (DOC) for RAM testing, register write protection, and independent watchdog timer with window function. These features reduce software overhead and external component count required for self-test and fault detection.

Can the R5F566NDHGFB#30 generate 5-phase complementary PWM waveforms?

Yes, the R5F566NDHGFB#30 supports 5-phase complementary PWM using its 32-bit GPTW timer module, which provides two output channels configured for 5-phase operation. This capability enables direct control of 5-phase stepper or BLDC motors without external gate drivers, with programmable dead times, synchronous start/stop, and ELC-triggered event coordination to maintain phase alignment under dynamic load conditions.

What is the purpose of the Trusted Secure IP Lite (TSIP-Lite) module in the R5F566NDHGFB#30?

The TSIP-Lite module in the R5F566NDHGFB#30 provides hardware-accelerated AES-128/256 encryption, true random number generation, and secure key management to protect firmware images and communication payloads. It prevents unauthorized access to the encryption engine and ensures safe storage of cryptographic keys-critical for secure bootloader validation, encrypted OTA updates, and tamper-resistant parameter storage in industrial and automotive applications.
