Renesas R5F566TKGGFB#10

Overview

R5F566TKGGFB#10 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 (no wait states), and integrated 3-phase/5-phase complementary PWM generation with 195 ps timing resolution - deployed in industrial servo drives and HVAC compressor control systems.

For engineers reviewing the R5F566TKGGFB#10 datasheet, R5F566TKGGFB#10 pinout, R5F566TKGGFB#10 application, or R5F566TKGGFB#10 equivalent, key selection criteria include its 144-pin LFQFP package with 110 GPIOs (4 × 5-V tolerant), dual 12-bit ADC units supporting simultaneous sampling across 30 channels, integrated CAN 2.0B interface, USB 2.0 FS host/function capability, and TSIP-Lite encryption for IEC 60730 Class B compliance.

Technical Context

The R5F566TKGGFB#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and configurable endianness. It integrates three independent 12-bit A/D converter units (S12ADH) - two with 3-channel sample-and-hold circuits and one with 14 channels - enabling synchronized sampling for motor current sensing.

Its timer subsystem combines ten 32-bit GPTW channels (160 MHz operation), nine 16-bit MTU3d channels, and four HRPWM channels delivering 195 ps minimum PWM edge placement resolution. The ELC enables event-triggered peripheral coordination without CPU intervention - critical for real-time motor commutation and fault response.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKGGFB#10?

The R5F566TKGGFB#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and integrated FPU - enabling real-time motor control algorithms with minimal latency. The R5F566TKGGFB#10 sustains this performance across its full operating temperature range (–40°C to +105°C) with no thermal throttling.

Does the R5F566TKGGFB#10 support simultaneous sampling across all 30 ADC channels?

No - the R5F566TKGGFB#10 supports simultaneous sampling only across channels within the same S12ADH unit: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels, no sample-and-hold). While all 30 channels can be scanned in sequence, true hardware-synchronized acquisition is limited to groups of up to 3 channels per unit. This architecture is optimized for concurrent phase current and DC-link voltage capture in 3-phase motor control.

What safety certifications does the R5F566TKGGFB#10 support out of the box?

The R5F566TKGGFB#10 includes hardware features required for IEC 60730 Class B compliance - including oscillation-stop detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM test-assisting function (DOC), CRC calculator (CRCA), and register write protection. These are implemented in silicon and documented in Renesas' Functional Safety Manual (R01UM0147EJ0200). No external components are needed to meet baseline self-test requirements.

Can the R5F566TKGGFB#10 operate with a 5 V supply on its I/O pins?

Yes - the R5F566TKGGFB#10 features 4 × 5-V tolerant I/O pins (confirmed in datasheet Table 1.1, "I/O ports for the 144-pin LFQFP"). These pins tolerate 5 V logic levels while the core operates from 2.7–5.5 V VCC, enabling direct interfacing with legacy 5 V sensors, optocouplers, and industrial fieldbus transceivers without level-shifting circuitry.

Is USB functionality available on the R5F566TKGGFB#10, and what modes does it support?

Yes - the R5F566TKGGFB#10 integrates a full-speed USB 2.0 interface (USBb module) supporting host, function, and OTG modes. It complies with USB 2.0 specifications, operates at 12 Mbps, includes 2 KB on-chip transfer RAM, and requires no external pull-up resistors. OTG operation is supported, though low-speed mode (1.5 Mbps) is host-only and not available in function mode.
