Product details
Overview
R5F566TAFDFL#50 from Renesas is a 32-bit RXv3 core MCU 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 R5F566TAFDFL#50 datasheet, R5F566TAFDFL#50 pinout, R5F566TAFDFL#50 application, or R5F566TAFDFL#50 equivalent, this device delivers deterministic real-time control with simultaneous sampling across three 12-bit A/D units (30 channels total), 32-channel CAN, full-speed USB 2.0 host/function/OTG, and IEC60730-compliant safety features including oscillation-stop detection, RAM ECC, and trusted secure IP Lite encryption.
Technical Context
The R5F566TAFDFL#50 implements the RXv3 CPU core with single-precision FPU, IEEE 754 compliance, and 111 instructions including DSP extensions. Its clock system supports PLL multiplication using 8–24 MHz external resonators or internal 16/18/20 MHz HOCO, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for synchronized GPTW/HRPWM operation.
Motor control execution relies on tightly coupled peripherals: 10-channel 32-bit GPTW timers with dead-time generation and synchronous start/stop, 9-channel MTU3d for 3-phase complementary PWM, 4-channel HRPWM for sub-nanosecond edge placement, and ELC-driven event chaining that initiates A/D conversion or PWM updates without CPU intervention during sleep modes.

The R5F566TAFDFL#50 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core with single-precision FPU, 111 instruction set, and optimized memory subsystem - enabling real-time execution of complex motor control algorithms such as field-oriented control (FOC) without latency bottlenecks. The R5F566TAFDFL#50 sustains this performance across its full temperature range (–40°C to +85°C).

These functions operate autonomously without CPU intervention, and the R5F566TAFDFL#50 documentation confirms their implementation per Annex H requirements for embedded control systems.
Can the R5F566TAFDFL#50 generate high-resolution PWM waveforms with sub-nanosecond timing control?
Yes, the R5F566TAFDFL#50 incorporates a dedicated High-Resolution PWM (HRPWM) module with 4 channels capable of 195 ps minimum timing resolution when operating at 160 MHz. This feature directly controls the rising/falling edges of GPTW0–GPTW3 outputs, enabling precise dead-time insertion and phase alignment for SiC/GaN-based inverter gate drivers.
