Renesas R5F566TEFGFP#10

Overview

R5F566TEFGFP#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control, featuring 160 MHz operation, 1 MB code flash, 128 KB SRAM, 32 KB data flash with 100,000 write cycles, and integrated high-resolution PWM (195 ps minimum resolution) for precise inverter timing. It supports IEC60730-compliant safety functions and operates across –40°C to +105°C.

For engineers reviewing the R5F566TEFGFP#10 datasheet, R5F566TEFGFP#10 pinout, R5F566TEFGFP#10 application, or R5F566TEFGFP#10 equivalent, key selection criteria include its 144-pin LFQFP package, dual 12-bit ADC units with PGA support, 3-phase/5-phase complementary PWM capability, CAN 2.0B interface, and TSIP-Lite encryption engine for secure firmware updates.

Technical Context

The R5F566TEFGFP#10 implements the RXv3 CPU core with single-precision FPU and IEEE 754 compliance, executing at up to 160 MHz with 928 CoreMark performance. 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).

Motor control execution relies on tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time generation, 9-channel MTU3d for 3-phase PWM, 4-channel HRPWM for sub-nanosecond edge placement, and ELC-driven event chaining that enables PWM-triggered ADC sampling without CPU intervention.

What is the maximum operating frequency and CoreMark score of the R5F566TEFGFP#10?

The R5F566TEFGFP#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with 32-bit multiplier, barrel shifter, and single-cycle instruction execution at full speed-enabling deterministic motor control loop execution within strict timing budgets.

Does the R5F566TEFGFP#10 support simultaneous sampling across all ADC units?

Yes, the R5F566TEFGFP#10 supports simultaneous sampling across its three 12-bit S12ADH ADC units (30 total channels) using hardware triggers from GPTW or MTU3 timers. This capability allows coordinated voltage and current measurements across multiple motor phases without software synchronization overhead.

What safety certifications and self-test features does the R5F566TEFGFP#10 include for IEC60730 compliance?

The R5F566TEFGFP#10 includes dedicated hardware for IEC60730 Class B compliance: oscillation-stop detection, clock accuracy measurement circuit (CAC), RAM test assistance via DOC, CRC calculator (CRCA), independent watchdog timer (IWDT), and register write protection. These features collectively satisfy mandatory self-diagnostic requirements for household appliance motor control.

How many CAN mailboxes does the R5F566TEFGFP#10 provide, and what protocol versions are supported?

The R5F566TEFGFP#10 integrates one CAN module compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) frame formats. It provides 32 configurable mailboxes with programmable acceptance filtering, enabling robust real-time communication for motor status reporting and diagnostics in industrial networks.

What is the resolution and timing capability of the HRPWM in the R5F566TEFGFP#10?

The R5F566TEFGFP#10 features four HRPWM channels capable of controlling the rising/falling edges of GPTW-generated PWM waveforms with a minimum resolution of 195 ps when operating at 160 MHz. This enables precise dead-time adjustment and harmonic reduction essential for high-efficiency SiC/GaN inverter designs.
