Renesas R5F566TKCDFP#30

Overview

R5F566TKCDFP#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial real-time 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 generation. It supports IEC60730 safety compliance and targets inverter-driven AC motor drives, servo controllers, and digital power supplies.

For engineers reviewing the R5F566TKCDFP#30 datasheet, R5F566TKCDFP#30 pinout, R5F566TKCDFP#30 application, or R5F566TKCDFP#30 equivalent, key selection considerations include its 144-pin LFQFP package with 110 GPIOs, 160-MHz GPTW timers with 195-ps HRPWM resolution, dual 12-bit ADC units supporting simultaneous sampling across 30 channels, and integrated CAN 2.0B + full-speed USB 2.0 host/function capability.

Technical Context

The R5F566TKCDFP#30 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111-instruction set including DSP extensions. Its clock system integrates PLL, high-speed on-chip oscillator (16–20 MHz), and low-speed oscillator (240 kHz), enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for precise timing control of GPTW, MTU3, and HRPWM modules.

Safety-critical operation is supported by hardware features including oscillation-stop detection, CAC clock accuracy measurement, CRCA CRC calculator, register write protection, Trusted Memory (blocks 8–9), and DOC-assisted RAM self-test - all aligned with IEC60730 Class B requirements for functional safety in motor control systems.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKCDFP#30?

The R5F566TKCDFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core with FPU, efficient instruction pipeline, and cache-enabled flash access - enabling deterministic execution of complex motor control algorithms within strict real-time deadlines. The R5F566TKCDFP#30 sustains this performance across its full industrial temperature range.

Does the R5F566TKCDFP#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TKCDFP#30 includes hardware features required for IEC60730 Class B: oscillation-stop detection, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), register write protection, DOC-assisted RAM test, and Trusted Memory. These are documented in the R01DS0315EJ0130 datasheet and enable certified safety routines without external components - though final system-level validation remains the responsibility of the end designer.

How many ADC channels does the R5F566TKCDFP#30 support, and can they sample simultaneously?

The R5F566TKCDFP#30 integrates three 12-bit S12ADH units totaling 30 channels (8+8+14), with two units featuring dedicated sample-and-hold circuits. All three units support hardware-synchronized start via shared triggers (e.g., from GPTW or MTU3), enabling true simultaneous sampling across up to 24 channels - critical for vector control of 3-phase motors where phase current and DC-link voltage must be captured in the same cycle.

What PWM resolution does the R5F566TKCDFP#30 provide, and how is it achieved?

The R5F566TKCDFP#30 delivers minimum PWM timing resolution of 195 ps using its 4-channel High-Resolution PWM (HRPWM) module, which overlays fine-grained delay control onto the base 32-bit GPTW timers. This resolution is realized at 160 MHz system clock and enables precise dead-time adjustment, phase skew correction, and gate driver timing margining - directly supporting high-efficiency SiC/GaN inverter designs where nanosecond-level control improves EMI and thermal performance.

Is the R5F566TKCDFP#30 pin-compatible with other RX66T variants like R5F566TKEDFP#30?

Yes, the R5F566TKCDFP#30 and R5F566TKEDFP#30 share identical 144-pin LFQFP (PLQP0144KA-B) mechanical and electrical pinouts, including identical power, clock, reset, and peripheral signal assignments. The only difference is temperature grade (D-grade: –40°C to +85°C vs. G-grade: –40°C to +105°C), making them drop-in replacements in hardware design - provided thermal management and qualification requirements align with the selected variant.
