Product details
Overview
R5F566TEBDFL#50 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 R5F566TEBDFL#50 datasheet, R5F566TEBDFL#50 pinout, R5F566TEBDFL#50 application, or R5F566TEBDFL#50 equivalent, this MCU delivers deterministic real-time control with dual 12-bit A/D converters (30-channel total), 6-channel analog comparators, CAN 2.0B interface, USB 2.0 FS host/function support, and IEC60730-compliant safety features including CAC, CRCA, and register write protection.
Technical Context
The R5F566TEBDFL#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 4-Gbyte linear address space. It integrates three independent 12-bit A/D units (S12ADH) supporting simultaneous sampling across 30 channels, with programmable gain amplifiers (6 channels) enabling pseudo-differential input for current sensing in motor drives.
Its timer subsystem combines ten 32-bit GPTW channels (160 MHz operation), nine 16-bit MTU3d channels, and four HRPWM channels synchronized to GPTW outputs-enabling sub-nanosecond dead-time control and phase-shifted PWM generation for field-oriented control (FOC) of PMSM and induction motors.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F566TEBDFL#50?
The R5F566TEBDFL#50 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark in benchmark testing. This performance level enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) with minimal jitter. The RXv3 core's single-cycle instruction execution and 4-Gbyte linear address space further ensure deterministic timing behavior critical for industrial drive applications.
Does the R5F566TEBDFL#50 support IEC60730 Class B compliance out of the box?
Yes, the R5F566TEBDFL#50 includes multiple hardware features required for IEC60730 Class B certification: clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), oscillation-stop detection, RAM test-assisting function via DOC, register write protection, and independent watchdog timer (IWDT). These are documented in the R01DS0315EJ0130 datasheet and do not require external components to satisfy self-test and fault-detection requirements.
What analog peripherals are integrated into the R5F566TEBDFL#50 for motor current sensing?
The R5F566TEBDFL#50 integrates three 12-bit A/D converter units (S12ADH) totaling 30 input channels, with three dedicated sample-and-hold circuits (two units with 3 channels each, one unit with 14 channels). It also includes six analog comparators (CMPC) and a programmable gain amplifier supporting pseudo-differential input across six channels - all optimized for simultaneous shunt-based current sensing in 3-phase motor drives without external signal conditioning.
What is the significance of the 195 ps HRPWM resolution in the R5F566TEBDFL#50?
The 195 ps minimum resolution of the High-Resolution PWM (HRPWM) in the R5F566TEBDFL#50 enables precise control of PWM edge placement at 160 MHz system clock, allowing nanosecond-level dead-time adjustment and phase alignment. This eliminates reliance on external dead-time ICs and reduces gate driver design complexity, especially critical for SiC and GaN-based inverters where timing errors directly impact efficiency and reliability.
Which package and temperature grade does the R5F566TEBDFL#50 use?
The R5F566TEBDFL#50 uses the PLQP0144KA-B package: a 144-pin low-profile quad flat package (LFQFP), 20 × 20 mm body size, 0.5 mm pitch, and is rated for –40°C to +105°C operation (G-version). This package supports high I/O count (110 GPIOs) with 5-V tolerant inputs and is qualified for industrial and automotive under-hood environments requiring extended thermal stability.
