Renesas R5F566TAEGFM#10

Overview

R5F566TAEGFM#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 on-chip code flash, 128 KB SRAM (no wait states), and integrated 3-phase/5-phase complementary PWM generation with 195 ps HRPWM timing resolution. It integrates CAN 2.0B, full-speed USB 2.0, and IEC60730-compliant safety features including independent watchdog timer, oscillation-stop detection, and RAM test assistance.

For engineers reviewing the R5F566TAEGFM#10 datasheet, R5F566TAEGFM#10 pinout, R5F566TAEGFM#10 application, or R5F566TAEGFM#10 equivalent, key selection considerations include its 144-pin LFQFP package with 110 GPIOs (4 × 5-V tolerant), dual 12-bit A/D converters supporting simultaneous sampling across 30 channels, and dedicated GPTW/MTU3 timers enabling precise dead-time control and phase-counting for PMSM/BLDC drives.

Technical Context

The R5F566TAEGFM#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian support. Its clock system combines an 8–24 MHz external resonator or 16–20 MHz HOCO with a PLL to generate up to 160 MHz ICLK, while peripheral clocks (PCLKA/PCLKC) run independently at up to 120 MHz and 160 MHz respectively-enabling high-speed PWM and ADC operation without CPU intervention.

Real-time control is enhanced by the Event Link Controller (ELC), which interconnects 188 internal event signals-including GPTW compare matches, MTU3 overflow, and A/D conversion triggers-to initiate module operations (e.g., ADC start, PWM output disable) without CPU overhead or interrupt latency. Safety-critical functions are supported by Trusted Secure IP Lite (AES-128/256, TRNG), CRC calculator (CRCA), and register write protection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAEGFM#10?

The R5F566TAEGFM#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance per the official Renesas benchmark. This reflects the efficiency of the RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem. The R5F566TAEGFM#10 sustains this performance across its full temperature range (–40°C to +105°C) with no frequency derating.

Does the R5F566TAEGFM#10 support simultaneous sampling across all 30 ADC channels?

The R5F566TAEGFM#10 supports simultaneous sampling across up to 7 channels per group using its three independent S12ADH units (Unit 0: 8 ch, Unit 1: 8 ch, Unit 2: 14 ch), but not across all 30 channels at once. Each unit can be triggered synchronously via ELC or external signal, enabling coordinated sampling of current, voltage, and temperature for field-oriented control. Full 30-channel simultaneous capture is not supported due to shared sample-and-hold resources.

What PWM resolution does the R5F566TAEGFM#10 provide for high-resolution timing control?

The R5F566TAEGFM#10 delivers a minimum PWM timing resolution of 195 ps using its 4-channel HRPWM circuit, which fine-tunes the rising/falling edges of waveforms generated by GPTW0–GPTW3. This resolution is achieved at 160 MHz system clock and enables precise dead-time adjustment, gate driver skew compensation, and harmonic suppression in high-efficiency inverters-critical for meeting EMI standards in industrial and appliance applications.

Is the R5F566TAEGFM#10 qualified for IEC60730 Class B compliance?

Yes, the R5F566TAEGFM#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, independent watchdog timer (IWDT) with window function, clock frequency accuracy measurement circuit (CAC), RAM test assistance via DOC, CRC calculator (CRCA), and register write protection. These capabilities reduce external component count and simplify certification for motor control and appliance applications.

What is the package type and pin count of the R5F566TAEGFM#10?

The R5F566TAEGFM#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B: 20 × 20 mm body, 0.5 mm pitch, and exposed thermal pad. It provides 110 general-purpose I/O pins-including 4 × 5-V tolerant inputs-making it suitable for high-density industrial control boards requiring mixed-voltage interfacing and robust noise immunity.
