Renesas R5F566TAAGFF#30

Overview

R5F566TAAGFF#30 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 3-phase/5-phase complementary PWM timers (GPTW/MTU3), high-resolution PWM (HRPWM) with 195 ps timing resolution, and dual 12-bit ADC units supporting simultaneous sampling across 30 channels.

For engineers reviewing the R5F566TAAGFF#30 datasheet, R5F566TAAGFF#30 pinout, R5F566TAAGFF#30 application, or R5F566TAAGFF#30 equivalent, key selection considerations include its 144-pin LFQFP package with 110 GPIOs (4× 5-V tolerant), integrated CAN 2.0B interface, full-speed USB 2.0 host/function/OTG support, TSIP-Lite encryption engine, and IEC60730-compliant safety features including oscillation-stop detection, RAM test assistance, and register write protection.

Technical Context

The R5F566TAAGFF#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and configurable endian mode. Its clock system integrates PLL with 8–24 MHz external crystal or 16–20 MHz HOCO reference, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz for timer/HRPWM reference).

Motor control functionality is anchored by ten 32-bit GPTW channels supporting single-/3-/5-phase complementary PWM with programmable dead time, nine 16-bit MTU3d channels with phase-counting and cascade operation, and four HRPWM channels delivering sub-nanosecond edge placement accuracy synchronized to GPTW outputs - all coordinated via the Event Link Controller (ELC) to eliminate CPU intervention during real-time waveform generation and A/D trigger sequencing.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAAGFF#30?

The R5F566TAAGFF#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, single-cycle instruction execution, and on-chip cache behavior - confirming deterministic real-time capability for motor control loops. The R5F566TAAGFF#30 sustains this performance across its full temperature range (–40°C to +105°C) with appropriate decoupling and thermal design.

Does the R5F566TAAGFF#30 support simultaneous sampling across multiple ADC units?

Yes, the R5F566TAAGFF#30 supports simultaneous sampling across three independent 12-bit S12ADH ADC units (totaling 30 channels). Unit 0 and Unit 1 each include three sample-and-hold circuits for pseudo-differential input, enabling concurrent current and voltage acquisition in motor control applications. This capability is hardware-triggered via ELC-linked GPTW/MTU3 events - ensuring sub-microsecond synchronization critical for FOC algorithms.

What PWM resolution and complementary output capabilities does the R5F566TAAGFF#30 provide?

The R5F566TAAGFF#30 delivers 195 ps minimum edge placement resolution via its four-channel HRPWM circuit synchronized to GPTW outputs. It supports single-phase (10 channels), 3-phase (3 channels), and 5-phase (2 channels) complementary PWM modes with automatic dead-time insertion and non-overlapping waveform generation - directly addressing SiC/GaN gate driver timing requirements in high-efficiency inverters.

Is the R5F566TAAGFF#30 qualified for IEC60730 Class B compliance?

Yes, the R5F566TAAGFF#30 includes dedicated hardware features for IEC60730 Class B compliance: main clock oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA), register write protection, analog input disconnection detection, and clock frequency accuracy measurement (CAC). These are documented in Renesas Application Note R01AN3919JJ0100 and validated in the RX66T Functional Safety Package.

What package type and pin count does the R5F566TAAGFF#30 use?

The R5F566TAAGFF#30 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. It provides 110 general-purpose I/O pins - including 4× 5-V tolerant inputs - and supports industrial temperature range (–40°C to +105°C). This package enables full peripheral access, including USB DP/DM, CAN TX/RX, and all 10 GPTW waveform output pins.
