Renesas R5F566TAFGFL#10

Overview

R5F566TAFGFL#10 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 code flash, 128 KB SRAM, and integrated 3-phase/5-phase complementary PWM timers (GPTW/MTU3), high-resolution PWM (195 ps min resolution), and dual 12-bit ADC units supporting simultaneous sampling across 30 channels.

For engineers reviewing the R5F566TAFGFL#10 datasheet, R5F566TAFGFL#10 pinout, R5F566TAFGFL#10 application, or R5F566TAFGFL#10 equivalent, this MCU delivers deterministic real-time motor control with hardware-accelerated event linking (ELC), on-chip FPU, IEC60730 safety features, and full-speed USB 2.0 + CAN 2.0B interfaces - critical for servo drives, HVAC inverters, and industrial PLCs.

Technical Context

The R5F566TAFGFL#10 implements the RXv3 CPU core with single-cycle 32×32→64-bit multiply, IEEE 754-compliant FPU, and configurable endian support. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) enabling precise timing separation for PWM, ADC, and communication modules.

Motor control execution relies on tightly coupled peripherals: 10-channel 32-bit GPTW with synchronous start/stop and dead-time generation, 9-channel 16-bit MTU3d with 3-phase complementary PWM output, 4-channel HRPWM (195 ps resolution), and ELC-driven trigger chaining between timers, ADC, and comparators - all operating without CPU intervention during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAFGFL#10?

The R5F566TAFGFL#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem - validated per Renesas R01DS0315EJ0130 Rev.1.30 datasheet page 1.

Does the R5F566TAFGFL#10 support simultaneous sampling across multiple ADC channels?

Yes, the R5F566TAFGFL#10 supports simultaneous sampling using three independent 12-bit S12ADH units - up to 7 channels concurrently - enabled by dedicated sample-and-hold circuits in Units 0 and 1. This capability is essential for accurate current reconstruction in 3-phase motor control, as confirmed in Section 1.1 of the R01DS0315EJ0130 datasheet.

What PWM resolution does the R5F566TAFGFL#10 achieve with its HRPWM module?

The R5F566TAFGFL#10 achieves a minimum PWM timing resolution of 195 ps using its 4-channel High-Resolution PWM (HRPWM) module, which refines the output of GPTW0–GPTW3 timers. This specification is measured at 160 MHz operation and enables precise dead-time control critical for high-efficiency inverter designs, per datasheet page 1 and Table 1.1.

Which safety standards does the R5F566TAFGFL#10 support for industrial certification?

The R5F566TAFGFL#10 includes hardware features supporting IEC60730 Class B compliance, including oscillation-stop detection, ADC disconnection monitoring, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function via DOC, and register write protection. These are documented in the "Useful functions for IEC60730 compliance" section of the R01DS0315EJ0130 datasheet.

What is the package type and pin count of the R5F566TAFGFL#10?

The R5F566TAFGFL#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with PLQP0144KA-B footprint - 20 × 20 mm body size and 0.5 mm pitch. It provides 110 general-purpose I/O pins, including 4 with 5-V tolerance, as specified in Table 1.1 and package outline diagrams of the R01DS0315EJ0130 datasheet.
