Renesas R5F566TEFGFL#10

Overview

R5F566TEFGFL#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 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 OTG, and TSIP-Lite encryption for IEC 60730-compliant safety-critical systems.

For engineers reviewing the R5F566TEFGFL#10 datasheet, R5F566TEFGFL#10 pinout, R5F566TEFGFL#10 application, or R5F566TEFGFL#10 equivalent, key selection criteria include its 144-pin LFQFP package with 110 GPIOs (4× 5-V tolerant), 160-MHz GPTW/MTU3 timer subsystem for real-time motor phase control, integrated PGA pseudo-differential amplifiers, and support for functional safety diagnostics including oscillation-stop detection, RAM test assistance, and CRC acceleration.

Technical Context

The R5F566TEFGFL#10 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 111-instruction set, and selectable little/big-endian data arrangement. Its clock system combines an 8–24 MHz external crystal oscillator with high-speed (16–20 MHz) and low-speed (240 kHz) on-chip oscillators, feeding a PLL to generate up to 160 MHz ICLK while supporting independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Real-time motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time generation, 9-channel 16-bit MTU3d with 3-phase complementary PWM output, and 4-channel HRPWM delivering 195 ps minimum edge placement resolution at 160 MHz - all coordinated via the Event Link Controller (ELC) to eliminate CPU intervention during critical timing sequences.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEFGFL#10?

The R5F566TEFGFL#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) and space-vector modulation, without requiring external accelerators. The R5F566TEFGFL#10 sustains this performance across its full temperature range (–40°C to +105°C) with no wait states in SRAM and optimized flash access via ROM cache.

Does the R5F566TEFGFL#10 support simultaneous sampling across multiple ADC channels?

Yes, the R5F566TEFGFL#10 supports simultaneous sampling across up to 7 channels using its three independent 12-bit S12ADH ADC units (Unit 0: 8 channels, Unit 1: 8 channels, Unit 2: 14 channels). This capability is essential for vector-controlled motor drives, enabling concurrent acquisition of three-phase currents and DC-link voltage within a single conversion cycle. The R5F566TEFGFL#10 uses ELC-triggered synchronization to ensure sub-microsecond timing alignment between units.

What PWM capabilities does the R5F566TEFGFL#10 provide for motor control?

The R5F566TEFGFL#10 integrates 10-channel 32-bit GPTW, 9-channel 16-bit MTU3d, and 4-channel HRPWM peripherals. It supports single-phase, 3-phase, and 5-phase complementary PWM modes with programmable dead time, automatic non-overlap enforcement, and 195 ps minimum edge resolution via HRPWM. These features allow the R5F566TEFGFL#10 to implement advanced motor control techniques such as sinusoidal drive, dead-time compensation, and hardware-accelerated fault response without CPU overhead.

Is the R5F566TEFGFL#10 qualified for functional safety standards like IEC 60730?

Yes, the R5F566TEFGFL#10 includes dedicated hardware for IEC 60730 Class B compliance: oscillation-stop detection, self-diagnostic ADC, RAM test assistance via DOC, CRC acceleration (CRCA), clock accuracy measurement (CAC), and register write protection. These features are documented in Renesas' Functional Safety Manual R01UM0592EJ0100 and enable certified implementations without external safety monitors. The R5F566TEFGFL#10 itself is not pre-certified, but its integrated functions reduce the effort required for end-product certification.

What package type and pin count does the R5F566TEFGFL#10 use?

The R5F566TEFGFL#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0144KA-B, measuring 20 mm × 20 mm with 0.5 mm pitch and an exposed thermal pad. It provides 110 general-purpose I/O pins, including 4× 5-V tolerant inputs, 15× large-current outputs, and dedicated pins for MTU3/GPTW PWM, ADC, CAN, USB, and debugging interfaces. This package supports high-density industrial PCB layouts while enabling efficient thermal dissipation in motor drive applications.
