Renesas R5F566TFEGFP#30

Overview

R5F566TFEGFP#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 high-resolution PWM (195 ps minimum resolution) for precise 3-phase/5-phase inverter gate timing.

For engineers reviewing the R5F566TFEGFP#30 datasheet, R5F566TFEGFP#30 pinout, R5F566TFEGFP#30 application, or R5F566TFEGFP#30 equivalent, this MCU delivers deterministic real-time control with simultaneous sampling across three 12-bit A/D units (30 channels total), 6-channel analog comparators, dual 12-bit D/A outputs, and ISO 11898-1 CAN interface - all in a 144-pin LFQFP package rated for –40°C to +105°C operation.

Technical Context

The R5F566TFEGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and configurable endian support. Its clock system integrates PLL synthesis 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 timing isolation.

Real-time motor control is enabled by tightly coupled peripherals: GPTW timers (10 channels, 32-bit) synchronized to PCLKC for PWM generation, HRPWM circuitry (4 channels) delivering 195 ps edge placement resolution, ELC-driven event chaining without CPU intervention, and MTU3d (9 channels) supporting 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TFEGFP#30?

The R5F566TFEGFP#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 real-time response in motor control loops. The R5F566TFEGFP#30 sustains this performance across its full temperature range (–40°C to +105°C) with no wait-state SRAM access.

Does the R5F566TFEGFP#30 support simultaneous sampling across multiple A/D channels?

Yes, the R5F566TFEGFP#30 integrates three independent 12-bit S12ADH units (totaling 30 channels) that support true simultaneous sampling - up to 7 channels across units - critical for accurate current/voltage vector acquisition in FOC motor control. Each unit includes dedicated sample-and-hold circuits (3 per unit for Units 0 and 1), and conversion triggers can be synchronized via MTU3d or ELC events. The R5F566TFEGFP#30 delivers 0.9 µs minimum conversion time at 60 MHz ADCLK.

What PWM resolution and channel count does the R5F566TFEGFP#30 provide for inverter gate control?

The R5F566TFEGFP#30 provides 32-bit GPTW timers (10 channels), 16-bit MTU3d (9 channels), and 4-channel HRPWM with 195 ps minimum edge placement resolution at 160 MHz - enabling sub-nanosecond timing accuracy for SiC/GaN gate drivers. It supports single-phase (10 outputs), 3-phase (3 outputs), and 5-phase (2 outputs) complementary PWM with automatic dead-time insertion, phase counting, and fault-triggered output disable via POE3B. This capability is fully implemented in the R5F566TFEGFP#30's 144-pin package.

Is the R5F566TFEGFP#30 qualified for IEC 60730 safety standards?

Yes, the R5F566TFEGFP#30 includes hardware features required for Class B compliance under IEC 60730: main clock oscillation-stop detection, RAM test assist (via DOC), CRC calculator (CRCA), register write protection, self-diagnostic A/D disconnection detection, and independent watchdog timer (IWDTa) with dedicated 120 kHz oscillator. These are documented in the R01DS0315EJ0130 datasheet and validated for use in safety-critical motor control applications. The R5F566TFEGFP#30 leverages these features without external components.

What communication interfaces are integrated into the R5F566TFEGFP#30?

The R5F566TFEGFP#30 integrates CAN (ISO 11898-1, 32 mailboxes), USB 2.0 full-speed host/function/OTG, RIICa (I²C/SMBus, 400 kbps), RSPIc (SPI, 30 Mbps), and seven SCI channels (asynchronous, SPI/I²C emulation, LIN). These interfaces operate independently with configurable clocks (PCLKA/PCLKB/PCLKD) and support ELC-triggered transfers - enabling robust fieldbus connectivity and PC-based firmware updates. All are natively supported in the R5F566TFEGFP#30 without external transceivers.
