Renesas R5F566TKGDFB#30

Overview

R5F566TKGDFB#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 (GPTW/MTU3) with 195 ps HRPWM resolution. It supports CAN 2.0B, full-speed USB 2.0 host/function/OTG, and IEC60730-compliant safety features including independent watchdog timer, oscillation-stop detection, and CRC acceleration.

For engineers reviewing the R5F566TKGDFB#30 datasheet, R5F566TKGDFB#30 pinout, R5F566TKGDFB#30 application, or R5F566TKGDFB#30 equivalent, key selection criteria include its 144-pin LFQFP package with 110 GPIOs (4× 5-V tolerant), dual 12-bit A/D converters with simultaneous sampling across 30 channels, programmable gain amplifiers for current sensing, and hardware-accelerated AES-128/256 encryption via TSIP-Lite - all validated for –40°C to +105°C operation.

Technical Context

The R5F566TKGDFB#30 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 111-instruction set, and little-endian (configurable to big-endian) data arrangement. Its clock system integrates PLL with 8–24 MHz external crystal or 16/18/20 MHz HOCO reference, enabling independent peripheral clock domains: ICLK up to 160 MHz, PCLKA up to 120 MHz (for GPTW/MTU3/HRPWM), PCLKB up to 60 MHz (for ADC/SPI/I²C), and BCLK up to 40 MHz for external bus interfacing.

Motor control execution relies on tightly coupled peripherals: 10-channel 32-bit GPTW with synchronous start/stop, dead-time generation, and ELC-triggered A/D conversion; 9-channel 16-bit MTU3d supporting 3-phase complementary PWM with automatic dead-time compensation; and 4-channel HRPWM delivering 195 ps timing resolution at 160 MHz - all synchronized to PCLKC. Safety-critical functions are enforced by MPU (8 regions), register write protection, Trusted Memory (blocks 8–9), and CAC-based clock accuracy monitoring.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKGDFB#30?

The R5F566TKGDFB#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance under benchmark conditions. This score reflects real-world execution efficiency of the RXv3 CPU core with its 111-instruction set, single-cycle execution capability, and integrated 32-bit multiplier/divider - verified in Renesas R01DS0315EJ0130 Rev.1.30 datasheet Section 1.1.

Does the R5F566TKGDFB#30 support simultaneous sampling across multiple A/D converter channels?

Yes, the R5F566TKGDFB#30 supports simultaneous sampling using three independent 12-bit S12ADH units (totaling 30 channels), with dedicated sample-and-hold circuits on Units 0 and 1 (3 channels each). This capability enables precise phase current acquisition in 3-phase motor control - confirmed in datasheet Table 1.1 and Section 1. Overview page 9.

What PWM resolution does the R5F566TKGDFB#30 provide for high-frequency inverter control?

The R5F566TKGDFB#30 delivers 195 ps minimum timing resolution on its 4-channel HRPWM subsystem, which refines the output of GPTW0–GPTW3 timers. This enables sub-nanosecond dead-time adjustment critical for SiC/GaN-based inverters - specified in datasheet Section 1. Overview page 7 and confirmed in R01DS0315EJ0130 Rev.1.30 Feature list.

Is the R5F566TKGDFB#30 qualified for extended temperature operation?

Yes, the R5F566TKGDFB#30 is the G-version device rated for –40°C to +105°C operation, making it suitable for demanding industrial environments such as motor drives in factory automation or outdoor renewable energy systems - explicitly stated in datasheet Table 1.1 "Operating temperature" on page 10.

Which debugging interfaces are supported by the R5F566TKGDFB#30?

The R5F566TKGDFB#30 supports both JTAG and one-line FINE debugging interfaces, enabling full-featured development with Renesas E2 studio and CS+ IDEs. The FINE interface reduces debug pin count to a single signal, simplifying board layout while retaining real-time trace and breakpoint capabilities - documented in datasheet Section 1.
