Renesas R5F566TFEGFP#10

Overview

R5F566TFEGFP#10 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 timing resolution) for precise 3-phase/5-phase inverter gate drive.

For engineers reviewing the R5F566TFEGFP#10 datasheet, R5F566TFEGFP#10 pinout, R5F566TFEGFP#10 application, or R5F566TFEGFP#10 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across three 12-bit A/D units, 32-channel CAN, full-speed USB 2.0 host/function support, and IEC60730-compliant safety features including CAC, CRCA, and register write protection.

Technical Context

The R5F566TFEGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 4-Gbyte linear address space. It integrates dual-clock domain architecture: ICLK up to 160 MHz for CPU and GPTW/MTU3, PCLKA up to 120 MHz for peripherals like RSPI/SCI11, and PCLKC up to 160 MHz as counter reference for HRPWM and GPTW timing.

Its motor control subsystem combines 10-channel 32-bit GPTW timers with 4-channel HRPWM for sub-nanosecond edge placement, MTU3d for 3-phase complementary PWM with automatic dead-time insertion, and ELC-driven event chaining enabling interrupt-free waveform synchronization with A/D conversion triggers and comparator outputs.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TFEGFP#10?

The R5F566TFEGFP#10 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. The R5F566TFEGFP#10 sustains this performance across its full operating voltage range (2.7–5.5 V) and temperature range (–40°C to +105°C), making it suitable for demanding real-time motor control tasks where deterministic timing is critical.

Does the R5F566TFEGFP#10 support simultaneous sampling across multiple A/D converter units?

Yes, the R5F566TFEGFP#10 supports simultaneous sampling across all three S12ADH units (30 total channels) using shared trigger sources such as GPTW compare events or ELC-linked signals. Each unit includes dedicated sample-and-hold circuits-three per unit for Units 0 and 1-and operates with independent clock domains (PCLKD up to 60 MHz). This capability enables precise time-aligned acquisition of phase currents, bus voltage, and temperature in inverter applications without software coordination overhead.

What PWM resolution does the R5F566TFEGFP#10 achieve, and how is it implemented?

The R5F566TFEGFP#10 achieves a minimum PWM edge resolution of 195 ps using its dedicated HRPWM circuit, which overlays fine timing control onto GPTW0–GPTW3 outputs. This resolution is realized at 160 MHz system clock operation and enables sub-nanosecond gate timing accuracy for SiC and GaN power devices. The HRPWM operates independently of the main GPTW counter, allowing dynamic dead-time adjustment and glitch-free edge placement without CPU intervention.

Which safety standards does the R5F566TFEGFP#10 support for industrial certification?

The R5F566TFEGFP#10 includes hardware features supporting IEC60730 Class B compliance, including clock accuracy measurement (CAC), CRC calculation (CRCA), oscillation-stop detection, RAM test assist via DOC, and register write protection. These functions are integrated into the silicon and require no external components. The R5F566TFEGFP#10 also supports Trusted Secure IP Lite (TSIP-Lite) for secure firmware authentication, further strengthening system-level safety architecture in certified industrial equipment.

What is the package type and thermal specification of the R5F566TFEGFP#10?

The R5F566TFEGFP#10 uses the PLQP0144KA-B package: a 144-pin low-profile quad flat package measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. It is rated for operation from –40°C to +105°C (G-version), with thermal resistance θ_JA of 30°C/W typical. The package supports reflow soldering per J-STD-020 and is compatible with standard PCB assembly processes used in industrial motor drive manufacturing.
