Renesas R5F566TEFDFP#30

Overview

R5F566TEFDFP#30 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 timers - deployed in HVAC compressors, servo drives, and industrial PMSM/BLDC motor systems.

For engineers reviewing the R5F566TEFDFP#30 datasheet, R5F566TEFDFP#30 pinout, R5F566TEFDFP#30 application, or R5F566TEFDFP#30 equivalent, key selection criteria include its 10-channel 32-bit GPTW timer with 195-ps HRPWM resolution, dual 12-bit A/D converters supporting simultaneous sampling across 30 channels, and ISO 11898-1 CAN interface with 32 mailboxes - all in a 144-pin LFQFP package rated for –40°C to +85°C operation.

Technical Context

The R5F566TEFDFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and configurable endian support. Its clock system integrates PLL, high-speed on-chip oscillator (16–20 MHz), and independent IWDT-dedicated 120-kHz oscillator - enabling precise timing for real-time motor control loops.

Peripheral coordination is managed via Event Link Controller (ELC), allowing 188 internal event signals to trigger module operations (e.g., A/D conversion start, PWM dead-time compensation) without CPU intervention - critical for deterministic response in safety-critical inverter gate drive sequences.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEFDFP#30?

The R5F566TEFDFP#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-bit multiplier/divider, and barrel shifter - all essential for real-time motor control computations. The R5F566TEFDFP#30 sustains this performance with zero wait-state access to 128 KB SRAM and optimized ROM cache usage.

Does the R5F566TEFDFP#30 support simultaneous sampling across all A/D channels?

Yes, the R5F566TEFDFP#30 integrates three independent 12-bit S12ADH units (30 total channels) that support true simultaneous sampling - critical for field-oriented control. Unit 0 and Unit 1 each include three sample-and-hold circuits, enabling concurrent acquisition of three-phase current signals. This capability is confirmed in the R01DS0315EJ0130 datasheet, Section 1.1, Table 1.1.

What PWM resolution does the R5F566TEFDFP#30 provide, and how is it achieved?

The R5F566TEFDFP#30 delivers 195 ps minimum resolution for high-resolution PWM (HRPWM) on four channels - achieved by refining the timing of GPTW0–GPTW3 outputs using dedicated HRPWM circuitry synchronized to the 160 MHz system clock. This resolution enables precise dead-time control for SiC and GaN power devices. The specification is explicitly stated in the "High-resolution PWM waveform generation circuit" section of the R01DS0315EJ0130 datasheet.

Is the R5F566TEFDFP#30 qualified for industrial temperature operation?

Yes, the R5F566TEFDFP#30 is rated for –40°C to +85°C operation (D-version), meeting industrial temperature requirements. Its design includes on-chip temperature sensor (±1.0°C accuracy), low-voltage detection (LVDA) with five selectable thresholds, and four low-power modes - ensuring reliable operation across thermal extremes in motor drive enclosures. This rating is specified in Table 1.1 of the R01DS0315EJ0130 datasheet.

What safety and security features does the R5F566TEFDFP#30 include for IEC 60730 compliance?

The R5F566TEFDFP#30 includes multiple IEC 60730-compliant features: oscillation-stop detection, RAM test assist (via DOC), CRC calculator (CRCA), register write protection, and independent watchdog timer (IWDTa) with window function. It also integrates Trusted Secure IP Lite (TSIP-Lite) with AES-128/256 and true random number generation. These capabilities are documented in the "Useful functions for IEC60730 compliance" section of the R01DS0315EJ0130 datasheet.
