Renesas R5F566TEFDFL#30

Overview

R5F566TEFDFL#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial real-time 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 - deployed in servo drives, inverters, and PLC I/O modules.

For engineers reviewing the R5F566TEFDFL#30 datasheet, R5F566TEFDFL#30 pinout, R5F566TEFDFL#30 application, or R5F566TEFDFL#30 equivalent, this MCU delivers deterministic timing via ELC-linked peripherals, high-resolution PWM (195 ps min. resolution), dual 12-bit ADC units with simultaneous sampling, and ISO 11898-1 CAN for robust fieldbus integration in safety-aware motion systems.

Technical Context

The R5F566TEFDFL#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian support. 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).

Real-time motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time control, 9-channel MTU3d for 3-phase PWM, 4-channel HRPWM with sub-ns edge placement, and ELC-driven event chaining that initiates A/D conversion or timer actions without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEFDFL#30?

The R5F566TEFDFL#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32×32→64-bit hardware multiplier, and IEEE 754-compliant FPU - all verified under standard EEMBC methodology at 160 MHz with cache enabled. The R5F566TEFDFL#30 sustains this performance across its full operating voltage range (2.7–5.5 V).

Does the R5F566TEFDFL#30 support simultaneous sampling across multiple ADC units?

Yes, the R5F566TEFDFL#30 supports true simultaneous sampling using three independent 12-bit S12ADH units - Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). All units can be triggered by a shared ELC event or timer signal, enabling synchronized acquisition of up to 7 analog inputs (e.g., three-phase currents and DC-link voltage) within a single 0.9 µs conversion window. This capability is essential for accurate field-oriented motor control in the R5F566TEFDFL#30.

What PWM resolution does the R5F566TEFDFL#30 achieve with its HRPWM feature?

The R5F566TEFDFL#30 achieves a minimum PWM edge placement resolution of 195 ps using its 4-channel High-Resolution PWM (HRPWM) circuit, which fine-tunes the rising/falling edges of GPTW0–GPTW3 outputs. This resolution is guaranteed at 160 MHz operation and enables precise dead-time control (<200 ps accuracy) critical for preventing shoot-through in high-voltage SiC or IGBT inverter stages - a key differentiator of the R5F566TEFDFL#30 in motor drive applications.

Which communication interfaces with functional safety support are integrated into the R5F566TEFDFL#30?

The R5F566TEFDFL#30 integrates ISO 11898-1-compliant CAN (1 channel, 32 mailboxes), USB 2.0 Full-Speed host/function/OTG, and multiple SCI channels - all supported by IEC 60730 Class B compliance features including oscillation-stop detection, CRC calculators (CRCA), clock accuracy measurement (CAC), and register write protection. These interfaces are validated for use in safety-critical subsystems such as motor feedback loops and diagnostics networks within the R5F566TEFDFL#30's target applications.

What is the package type and pin count of the R5F566TEFDFL#30?

The R5F566TEFDFL#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0144KA-B, measuring 20 × 20 mm with 0.5 mm pitch. It provides 110 general-purpose I/O pins - including 4 with 5-V tolerance, 15 high-current outputs, and full support for JTAG/FINE debugging. This package is specified for industrial temperature range (–40°C to +85°C) and is RoHS compliant - matching the mechanical and thermal requirements of the R5F566TEFDFL#30's intended use cases.
