Renesas R5F566TEADFP#30

Overview

R5F566TEADFP#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 160 MHz with 1 MB on-chip code flash, 128 KB SRAM, 32 KB data flash, integrated 12-bit A/D converter (30-channel), 32-bit GPTW timers (10 channels), and 4-channel high-resolution PWM with 195 ps minimum timing resolution. It supports CAN 2.0B, full-speed USB 2.0, and IEC60730 safety-compliant features including oscillation-stop detection, RAM test assistance, and CRC calculation.

For engineers reviewing the R5F566TEADFP#30 datasheet, R5F566TEADFP#30 pinout, R5F566TEADFP#30 application, or R5F566TEADFP#30 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across three 12-bit A/D units, 3-phase/5-phase complementary PWM generation, and hardware-accelerated encryption (AES-128/256) - critical for servo drives, HVAC inverters, and industrial PLCs requiring functional safety certification.

Technical Context

The R5F566TEADFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 111-instruction set including DSP extensions. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and dedicated IWDT oscillator (120 kHz), enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for precise timer and ADC synchronization.

Motor control functionality is anchored by the 32-bit GPTW (10 channels), MTU3d (9 channels), and HRPWM (4 channels), all coordinated via Event Link Controller (ELC) to trigger ADC conversions, manage dead-time compensation, and execute phase-counting without CPU intervention - essential for field-oriented control (FOC) in brushless DC and permanent magnet synchronous motors.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEADFP#30?

The R5F566TEADFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark in benchmark testing. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 8-KB ROM cache, and efficient pipeline - allowing the R5F566TEADFP#30 to execute complex field-oriented control algorithms within strict real-time deadlines typical of motor drive applications.

Does the R5F566TEADFP#30 support simultaneous sampling across its A/D converters?

Yes, the R5F566TEADFP#30 integrates three independent 12-bit S12ADH units (totaling 30 channels) capable of true simultaneous sampling. Unit 0 and Unit 1 each include three sample-and-hold circuits, enabling concurrent acquisition of up to six analog signals - critical for capturing phase currents and DC-link voltage without inter-channel skew in the R5F566TEADFP#30-based inverter designs.

What PWM resolution does the R5F566TEADFP#30 provide, and how is it achieved?

The R5F566TEADFP#30 delivers a minimum PWM timing resolution of 195 ps through its 4-channel High-Resolution PWM (HRPWM) module, which fine-tunes the edge timing of outputs generated by GPTW0–GPTW3. This capability is realized using dedicated high-speed clock paths synchronized to the 160 MHz PCLKC domain - enabling precise dead-time control essential for SiC/GaN-based inverters using the R5F566TEADFP#30.

Which safety standards and features does the R5F566TEADFP#30 support for industrial certification?

The R5F566TEADFP#30 includes IEC60730 Class B compliance features: oscillation-stop detection, RAM test assistance via DOC, CRCA for data integrity, register write protection, and Trusted Memory for code flash blocks 8–9. These capabilities - documented in the R01DS0315EJ0130 datasheet - allow developers to meet functional safety requirements in motor control systems without external supervision hardware when using the R5F566TEADFP#30.

What is the package type and pin count of the R5F566TEADFP#30?

The R5F566TEADFP#30 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch. It provides 110 general-purpose I/O pins - including 4 × 5-V tolerant, 15 × large-current drive, and configurable pull-up/open-drain - matching the full-featured variant of the RX66T Group and ensuring compatibility with existing 144-pin motor control reference designs using the R5F566TEADFP#30.
