Renesas R5F566TFFGFP#30

Overview

R5F566TFFGFP#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 generation with 195 ps timing resolution. It integrates CAN, USB 2.0 FS host/function, 12-bit ADC with simultaneous sampling across three units (30 channels total), and TSIP-Lite encryption for IEC60730-compliant safety-critical systems.

For engineers reviewing the R5F566TFFGFP#30 datasheet, R5F566TFFGFP#30 pinout, R5F566TFFGFP#30 application, or R5F566TFFGFP#30 equivalent, this MCU delivers deterministic real-time motor control with hardware-accelerated PWM, event-driven peripheral coordination via ELC, and robust functional safety features including oscillation-stop detection, RAM ECC, CRC acceleration, and register write protection - all in a 144-pin LFQFP package with 5-V tolerant I/O.

Technical Context

The R5F566TFFGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 111-instruction set including DSP extensions. Its clock system supports PLL multiplication using 8–24 MHz external crystals or internal 16–20 MHz HOCO, enabling independent domain clocks: ICLK up to 160 MHz, PCLKA up to 120 MHz for GPTW/MTU3/HRPWM, and PCLKD up to 60 MHz for S12ADH.

Peripheral integration centers on high-precision motor control: ten 32-bit GPTW channels support single-/3-/5-phase complementary PWM with dead-time insertion and synchronous start/stop; six CMPC comparators interface with analog inputs; and the ELC enables interrupt-free inter-module triggering - e.g., MTU3/GPTW events initiating ADC conversions or disabling PWM outputs on fault detection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TFFGFP#30?

The R5F566TFFGFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance under benchmark conditions. This score reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and integrated FPU - enabling deterministic real-time motor control loops with sub-microsecond jitter. The R5F566TFFGFP#30 sustains this performance across its full voltage range (2.7–5.5 V) and temperature grade (–40°C to +105°C).

Does the R5F566TFFGFP#30 support simultaneous sampling across multiple ADC channels?

Yes, the R5F566TFFGFP#30 integrates three independent 12-bit S12ADH ADC units capable of simultaneous sampling: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This allows concurrent acquisition of phase currents and DC-link voltage in 3-phase motor control - critical for accurate field-oriented control without sampling skew. The R5F566TFFGFP#30 supports up to 7-channel simultaneous sampling across Units 0 and 1.

What PWM resolution and complementary modes does the R5F566TFFGFP#30 provide?

The R5F566TFFGFP#30 delivers 32-bit GPTW timers (10 channels) with 3-phase, 5-phase, and single-phase complementary PWM modes, plus 4-channel HRPWM offering 195 ps minimum timing resolution at 160 MHz. It supports automatic dead-time insertion, synchronous start/stop across channels, and fault-driven output disable via POE3B/POEG. These capabilities make the R5F566TFFGFP#30 suitable for driving SiC and GaN inverters requiring nanosecond-level timing precision.

Is the R5F566TFFGFP#30 qualified for IEC60730 functional safety compliance?

Yes, the R5F566TFFGFP#30 includes hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function via DOC, independent watchdog timer (IWDT), and register write protection. These are documented in Renesas' Functional Safety Manual R01UM0137EJ0100 and validated in the R5F566TFFGFP#30's silicon implementation - enabling self-test routines without external components.

What is the package type and pin count of the R5F566TFFGFP#30?

The R5F566TFFGFP#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B: 20 mm × 20 mm body, 0.5 mm pitch, and exposed thermal pad. It provides 110 general-purpose I/O pins - including 4 with 5-V tolerance, 110 with pull-up resistors, and 110 supporting open-drain operation - making it suitable for high-density industrial control PCB layouts requiring robust noise immunity and thermal management.
