Renesas R5F566TAFDFL#30

Overview

R5F566TAFDFL#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 timers. It supports IEC60730 functional safety compliance and targets real-time control of AC induction and PMSM motors in HVAC compressors and industrial drives.

For engineers reviewing the R5F566TAFDFL#30 datasheet, R5F566TAFDFL#30 pinout, R5F566TAFDFL#30 application, or R5F566TAFDFL#30 equivalent, key selection criteria include its 10-channel 32-bit GPTW timer with 195 ps HRPWM resolution, dual 12-bit A/D converters with simultaneous sampling across 30 channels, CAN 2.0B interface, USB 2.0 FS host/function capability, and 144-pin LFQFP package with 110 GPIOs including 5-V tolerant pins.

Technical Context

The R5F566TAFDFL#30 implements the RXv3 CPU core with single-precision FPU and IEEE 754 compliance, executing instructions at up to 160 MHz with zero-wait access to 128 KB SRAM and 1 MB flash (with ROM cache). Its clock system integrates PLL, high-speed on-chip oscillator (16–20 MHz), and low-speed oscillator (240 kHz), enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for precise timing control of GPTW, MTU3, and HRPWM modules.

Motor control functionality is anchored by three synchronized timer subsystems: ten 32-bit GPTW channels supporting single-/3-/5-phase complementary PWM with programmable dead time and synchronous start/stop; nine 16-bit MTU3d channels with phase-counting and cascade operation; and four HRPWM channels delivering 195 ps minimum edge timing resolution for gate driver synchronization. All are coordinated via the Event Link Controller (ELC) to trigger A/D conversion, comparator events, or port output enable without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAFDFL#30?

The R5F566TAFDFL#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and zero-wait access to 128 KB SRAM - enabling real-time execution of complex motor control algorithms such as field-oriented control and model predictive control without external acceleration.

Does the R5F566TAFDFL#30 support IEC60730 Class B compliance for motor control safety?

Yes, the R5F566TAFDFL#30 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, RAM test-assisting function via DOC, CRC calculator (CRCA), and register write protection. These are documented in the R01DS0315EJ0130 datasheet and enable systematic self-test routines essential for industrial inverter safety certification.

What PWM resolution and channel count does the R5F566TAFDFL#30 provide for motor inverter control?

The R5F566TAFDFL#30 provides three-tiered PWM capability: ten 32-bit GPTW channels supporting single-/3-/5-phase complementary PWM; nine 16-bit MTU3d channels with phase-counting mode; and four HRPWM channels delivering 195 ps minimum edge timing resolution at 160 MHz. This allows precise dead-time insertion, gate driver synchronization, and multi-phase inverter control - critical for SiC/GaN-based high-efficiency drives.

How many analog-to-digital converter channels does the R5F566TAFDFL#30 support, and what is their sampling capability?

The R5F566TAFDFL#30 integrates three 12-bit S12ADH units totaling 30 input channels: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). It supports simultaneous sampling across all three units, with minimum conversion time of 0.9 µs per channel at 60 MHz ADCLK - enabling synchronized current and voltage acquisition for sensorless FOC algorithms in real-time motor control applications.

What package type and pin count does the R5F566TAFDFL#30 use, and is it RoHS compliant?

The R5F566TAFDFL#30 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch and an exposed thermal pad. It is RoHS compliant and rated for industrial temperature range (–40°C to +85°C). The package provides 110 general-purpose I/O pins, including 4 with 5-V tolerance, supporting direct interface with industrial-level sensors and actuators without level-shifting circuitry.
