Renesas R5F566TFGDFP#30

Overview

R5F566TFGDFP#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 high-resolution PWM (195 ps minimum resolution) for precise 3-phase/5-phase inverter gate timing.

For engineers reviewing the R5F566TFGDFP#30 datasheet, R5F566TFGDFP#30 pinout, R5F566TFGDFP#30 application, or R5F566TFGDFP#30 equivalent, this MCU delivers deterministic real-time control with simultaneous sampling across three 12-bit A/D units (30 channels total), embedded TSIP-Lite encryption, IEC60730 safety support, and dual CAN/USB FS interfaces - all in a 144-pin LFQFP package with 5-V-tolerant I/O.

Technical Context

The R5F566TFGDFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent peripheral clock domains (ICLK up to 160 MHz, PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Real-time motor control is enabled by tightly coupled peripherals: ten 32-bit GPTW timers with complementary PWM and dead-time generation, nine 16-bit MTU3d channels, four HRPWM outputs synchronized to GPTW, and event-linking controller (ELC) that triggers timer actions without CPU intervention - including during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TFGDFP#30?

The R5F566TFGDFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance under benchmark conditions. This reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and integrated FPU - enabling deterministic real-time motor control loop execution within strict timing budgets.

Does the R5F566TFGDFP#30 support simultaneous sampling across all 30 A/D channels?

No - the R5F566TFGDFP#30 supports simultaneous sampling only across channels within the same S12ADH unit (Unit 0: 8 channels, Unit 1: 8 channels, Unit 2: 14 channels). However, hardware triggers from GPTW or MTU3 can synchronize start times across units with sub-microsecond skew, enabling effectively concurrent acquisition for multi-axis current sensing.

What PWM resolution does the R5F566TFGDFP#30 achieve, and how is it implemented?

The R5F566TFGDFP#30 achieves a minimum PWM edge placement resolution of 195 ps using its HRPWM circuit synchronized to GPTW0–GPTW3. This is derived from the 160 MHz PCLKC reference clock divided by 128, enabling precise dead-time control essential for SiC/GaN-based inverters without external timing ICs.

Is the R5F566TFGDFP#30 qualified for automotive applications?

The R5F566TFGDFP#30 is rated for –40°C to +105°C (G-version) and includes IEC60730 Class B safety features, but it is not AEC-Q100 qualified. It is suitable for automotive auxiliary systems (e.g., HVAC blowers, EPS assist) where functional safety requirements are met through system-level design, not component-level qualification.

What debugging interfaces does the R5F566TFGDFP#30 support?

The R5F566TFGDFP#30 supports both JTAG and one-line FINE debugging interfaces. JTAG enables full boundary-scan and complex breakpoint debugging, while FINE provides minimal-pin-count in-circuit debugging - ideal for space-constrained motor control PCBs where trace routing is limited.
