Renesas R5F566TFGGFB#30

Overview

R5F566TFGGFB#30 from Renesas is a 32-bit RXv3 microcontroller optimized for real-time motor control in industrial inverters and servo drives, operating at up to 160 MHz with 1 MB on-chip code flash, 128 KB SRAM (no wait states), 32 KB reprogrammable data flash, and integrated 3-phase/5-phase complementary PWM generation across 10 GPTW channels.

For engineers reviewing the R5F566TFGGFB#30 datasheet, R5F566TFGGFB#30 pinout, R5F566TFGGFB#30 application, or R5F566TFGGFB#30 equivalent, this MCU delivers deterministic timing for field-oriented control (FOC), supports IEC 60730 Class B safety compliance via oscillation-stop detection, RAM test assistance, and CRC acceleration, and integrates USB 2.0 FS host/function, CAN 2.0B, and high-resolution PWM with 195 ps timing resolution.

Technical Context

The R5F566TFGGFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 111-instruction set including DSP extensions. Its clock system uses an 8–24 MHz external resonator or 16–20 MHz HOCO as PLL reference, generating independent bus clocks: ICLK up to 160 MHz, PCLKA up to 120 MHz (for GPTW/MTU3), and PCLKD up to 60 MHz (for S12ADH).

Real-time motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time insertion, 9-channel 16-bit MTU3d supporting 3-phase complementary PWM, 4-channel HRPWM with 195 ps minimum resolution, and ELC-driven event chaining that triggers A/D conversion or PWM updates without CPU intervention during sleep modes.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and core architecture of the R5F566TFGGFB#30?

The R5F566TFGGFB#30 operates at a maximum frequency of 160 MHz using the 32-bit RXv3 CPU core, achieving 928 CoreMark performance. It includes a single-precision FPU compliant with IEEE 754, 111 instructions (including DSP extensions), and a 4-Gbyte linear address space. This architecture delivers deterministic real-time response essential for field-oriented motor control loops executed in under 1 µs.

Does the R5F566TFGGFB#30 support IEC 60730 Class B functional safety certification?

Yes, the R5F566TFGGFB#30 includes multiple hardware features required for IEC 60730 Class B compliance: oscillation-stop detection for main clock failure, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function via DOC, independent watchdog timer (IWDTa), and register write protection. These reduce software validation burden and support self-test routines without external components.

What PWM capabilities does the R5F566TFGGFB#30 offer for motor control applications?

The R5F566TFGGFB#30 provides three-tiered PWM generation: 10-channel 32-bit GPTW timers with single/3-phase/5-phase complementary modes, 9-channel 16-bit MTU3d for 3-phase PWM with automatic dead-time insertion, and 4-channel HRPWM delivering 195 ps minimum timing resolution. All are synchronized via ELC to ADC triggers, enabling precise current sampling aligned to PWM center points for optimal FOC accuracy.

How much on-chip memory does the R5F566TFGGFB#30 include, and what are its key attributes?

The R5F566TFGGFB#30 integrates 1 MB of code flash memory (with ROM cache support), 128 KB of zero-wait-state SRAM, 16 KB of ECC-protected SRAM, and 32 KB of data flash rated for 100,000 erase/write cycles. The data flash supports background programming/erasing (BGO), allowing firmware updates and parameter logging without halting real-time control execution.

What communication interfaces are integrated into the R5F566TFGGFB#30?

The R5F566TFGGFB#30 integrates USB 2.0 Full-Speed host/function (with 2 KB buffer), CAN 2.0B (32 mailboxes), seven SCI channels (including FIFO-buffered SCI11 and LIN-capable SCI12), one I2C interface (RIICa, 400 kbps), and one high-speed SPI (RSPIc, 30 Mbps). These enable concurrent PC debugging, industrial fieldbus connectivity, and sensor/actuator interfacing in compact motor drive designs.
