Renesas R5F566TFGDFB#30

Overview

R5F566TFGDFB#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for industrial motor control and power conversion systems, 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 integrates 32-channel 12-bit A/D converters with simultaneous sampling, 6-channel analog comparators, 2-channel 12-bit D/A converters, and hardware-accelerated AES-128/256 encryption via TSIP-Lite.

For engineers reviewing the R5F566TFGDFB#30 datasheet, R5F566TFGDFB#30 pinout, R5F566TFGDFB#30 application, or R5F566TFGDFB#30 equivalent, key selection criteria include its 144-pin LFQFP package with 110 general-purpose I/Os (4× 5-V tolerant), 10-channel 32-bit GPTW timers supporting 195-ps HRPWM resolution, CAN 2.0B compliance, full-speed USB 2.0 host/function capability, and IEC60730 safety support including oscillation-stop detection and RAM self-test.

Technical Context

The R5F566TFGDFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 4-Gbyte linear address space. Its clock system combines an 8–24 MHz external crystal oscillator with internal 16/18/20 MHz HOCO and 240 kHz LOCO, feeding a PLL to achieve 160 MHz ICLK while independently configuring PCLKA (up to 120 MHz), PCLKB (60 MHz), PCLKC (160 MHz), and PCLKD (60 MHz) for peripheral domains.

Peripheral timing is tightly coordinated: GPTW and MTU3 timers use PCLKC as counter reference for high-resolution PWM and dead-time control; S12ADH A/D converter runs on PCLKD at up to 60 MHz for 0.9 µs minimum conversion time; USBb module operates at 48 MHz derived from PLL; and CAN bus logic synchronizes to PCLKB. Event Link Controller (ELC) enables 188 internal event signals to trigger module operations without CPU intervention - critical for deterministic real-time motor control loops.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TFGDFB#30?

The R5F566TFGDFB#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 on-chip 8-KB ROM cache - enabling deterministic real-time response in motor control applications where loop timing must remain sub-microsecond.

Does the R5F566TFGDFB#30 support simultaneous sampling across all 30 A/D channels?

No - the R5F566TFGDFB#30 supports simultaneous sampling only within each of its three independent S12ADH units: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels, no dedicated sample-and-hold). While all 30 channels share the same 12-bit resolution and 0.9 µs conversion time, true simultaneous capture across all channels requires external synchronization via ELC-triggered start signals.

What is the purpose of the HRPWM feature in the R5F566TFGDFB#30?

The HRPWM (High-Resolution PWM) feature in the R5F566TFGDFB#30 enables 195 ps minimum resolution for edge placement on GPTW0–GPTW3 outputs when operating at 160 MHz. This allows precise dead-time insertion and phase alignment in 3-phase inverter gate drivers - critical for minimizing shoot-through current and optimizing efficiency in high-frequency SiC/GaN-based power stages.

Can the R5F566TFGDFB#30 operate with a 5-V supply voltage?

Yes - the R5F566TFGDFB#30 supports a VCC supply range of 2.7 V to 5.5 V and includes 4 GPIO pins rated for 5-V tolerance. However, analog supply rails AVCC0/1/2 require 3.0–5.5 V (≥ VCC), and USB operation mandates VCC_USB at 3.0–3.6 V. Full 5-V operation is viable only when USB is disabled and analog supplies are configured accordingly.

How does the R5F566TFGDFB#30 support IEC60730 Class B compliance?

The R5F566TFGDFB#30 supports IEC60730 Class B compliance through integrated hardware features: main clock oscillation-stop detection, CRC calculator (CRCA) for memory/data integrity, RAM test-assist function using DOC, independent watchdog timer (IWDTa) with dedicated 120-kHz oscillator, and register write protection. These eliminate need for external diagnostic components in safety-critical motor control designs.
