Renesas R5F566TAFGFP#10

Overview

R5F566TAFGFP#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. It supports IEC60730 safety compliance and targets real-time closed-loop motor drive systems.

For engineers reviewing the R5F566TAFGFP#10 datasheet, R5F566TAFGFP#10 pinout, R5F566TAFGFP#10 application, or R5F566TAFGFP#10 equivalent, key selection criteria include its 144-pin LFQFP package, 160 MHz GPTW/MTU3 timer subsystem, HRPWM sub-ns edge control, dual 12-bit ADC units with PGA support, and CAN 2.0B + USB 2.0 FS interface integration.

Technical Context

The R5F566TAFGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. Its clock system integrates PLL, high-speed (16–20 MHz) and low-speed (240 kHz) on-chip oscillators, and independent IWDT-dedicated 120 kHz oscillator - all supporting dynamic frequency scaling across four low-power modes.

Peripheral coordination is managed via Event Link Controller (ELC), enabling interrupt-free inter-module triggering (e.g., MTU3/GPTW start A/D conversion, comparator events disabling PWM outputs). Safety features include MPU, Trusted Memory (blocks 8–9), register write protection, CAC clock accuracy monitoring, and CRCA CRC calculation for firmware integrity verification.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAFGFP#10?

The R5F566TAFGFP#10 operates at a maximum frequency of 160 MHz and delivers 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32×32→64-bit multiplier, and IEEE 754-compliant FPU - enabling deterministic real-time motor control loops with sub-10 µs latency. The R5F566TAFGFP#10 sustains this performance across its full temperature range (–40°C to +105°C).

Does the R5F566TAFGFP#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TAFGFP#10 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), RAM test-assisting function via DOC, CRC calculator (CRCA), independent watchdog timer (IWDT), and register write protection. These reduce firmware validation effort and enable certified safety routines without external components - a key advantage of the R5F566TAFGFP#10 in white-goods and industrial drive applications.

What analog peripherals are integrated into the R5F566TAFGFP#10 for motor current sensing?

The R5F566TAFGFP#10 integrates three 12-bit S12ADH ADC units (30 total channels), six-channel analog comparator (CMPC), two 12-bit D/A converters, and a six-channel programmable gain amplifier (PGA) - three PGA channels per ADC unit. This allows pseudo-differential shunt current sensing with 1×/2×/4×/8× gain, simultaneous sampling across phases, and comparator-based overcurrent detection - eliminating external op-amps and reducing BOM in motor control designs using the R5F566TAFGFP#10.

How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F566TAFGFP#10?

The ELC in the R5F566TAFGFP#10 enables 188 internal event signals (e.g., MTU3 overflow, GPTW compare match, comparator output) to trigger peripheral actions - such as starting A/D conversion, disabling PWM outputs, or toggling GPIO - without CPU interrupt latency. This allows deterministic sub-microsecond reaction to faults or timing events, critical for safe inverter shutdown and precise commutation sequencing in the R5F566TAFGFP#10-based systems.

What is the package type and thermal specification of the R5F566TAFGFP#10?

The R5F566TAFGFP#10 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. It is rated for industrial temperature operation from –40°C to +105°C (G-grade), with power supply voltage range of 2.7–5.5 V. This package supports high I/O density and thermal dissipation needed for sustained 160 MHz operation in motor control applications using the R5F566TAFGFP#10.
