Renesas R5F566TEBDFL#10

Overview

R5F566TEBDFL#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 integrates dual 12-bit ADC units with simultaneous sampling across 30 channels, 6-channel analog comparators, 2-channel 12-bit DACs, CAN 2.0B, full-speed USB 2.0 host/function/OTG, and TSIP-Lite encryption.

For engineers reviewing the R5F566TEBDFL#10 datasheet, R5F566TEBDFL#10 pinout, R5F566TEBDFL#10 application, or R5F566TEBDFL#10 equivalent, this MCU delivers deterministic real-time motor control with hardware-accelerated PWM synchronization, ELC-triggered peripheral coordination, and IEC60730-compliant safety features including oscillation-stop detection, RAM ECC, CRC acceleration, and register write protection - critical for BLDC/PMSM inverter designs requiring functional safety certification.

Technical Context

The R5F566TEBDFL#10 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 111-instruction set, and 32×32→64-bit multiplier. Its clock system supports PLL multiplication using 8–24 MHz external crystals or 16/18/20 MHz HOCO, delivering independent ICLK (up to 160 MHz), PCLKA (120 MHz), PCLKB/C/D (60–160 MHz), and BCLK (40 MHz) domains for precise peripheral timing.

Motor control execution relies on tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time generation, 9-channel 16-bit MTU3d supporting 3-phase complementary PWM, and 4-channel HRPWM enabling sub-200 ps edge placement. The ELC enables interrupt-free inter-module triggering - e.g., GPTW compare events directly initiating A/D conversion or disabling output pins via POEG/POE3B on fault detection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEBDFL#10?

The R5F566TEBDFL#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficiency in executing real-time motor control algorithms, including field-oriented control (FOC) loops, without external co-processors. The R5F566TEBDFL#10 sustains this performance across its full temperature range (–40°C to +105°C) with no derating.

Does the R5F566TEBDFL#10 support simultaneous sampling across all 30 ADC channels?

No - the R5F566TEBDFL#10 supports simultaneous sampling across up to 7 channels using its three independent S12ADH units (Unit 0: 8 ch, Unit 1: 8 ch, Unit 2: 14 ch), but not all 30 channels at once. Units 0 and 1 each include three sample-and-hold circuits enabling true concurrent capture of current/voltage pairs. The R5F566TEBDFL#10 uses ELC-triggered sequencing to minimize inter-channel skew in multi-unit scans.

What safety certifications does the R5F566TEBDFL#10 support out of the box?

The R5F566TEBDFL#10 includes hardware features aligned with IEC60730 Class B requirements: oscillation-stop detection, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test assist (DOC), register write protection, and memory protection unit (MPU). These allow certified implementations without external components. The R5F566TEBDFL#10 itself is not pre-certified, but its integrated safety mechanisms reduce qualification effort significantly.

Can the R5F566TEBDFL#10 generate 5-phase complementary PWM waveforms?

Yes - the R5F566TEBDFL#10's 32-bit GPTW timers support 5-phase complementary PWM mode with two output channels, enabling direct control of 5-phase stepper or BLDC motors. Each channel provides independent dead-time insertion and phase-shift control. The R5F566TEBDFL#10 also supports 3-phase (3 channels) and single-phase (10 channels) modes, all synchronized via ELC for jitter-free operation.

Is USB functionality available on the R5F566TEBDFL#10, and what modes does it support?

Yes - the R5F566TEBDFL#10 integrates a full-speed USB 2.0 module compliant with USB 2.0 specification, supporting host, function, and OTG modes. It operates at 12 Mbps (full speed) and includes 2 KB on-chip RAM for transfer buffering. External pull-up/pull-down resistors are unnecessary. The R5F566TEBDFL#10 does not support low-speed USB (1.5 Mbps) in host mode, and OTG operation excludes low-speed devices.
