Renesas R5F566TAEGFN#30

Overview

R5F566TAEGFN#30 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 timers - deployed in HVAC compressors, servo drives, and EV traction inverters.

For engineers reviewing the R5F566TAEGFN#30 datasheet, R5F566TAEGFN#30 pinout, R5F566TAEGFN#30 application, or R5F566TAEGFN#30 equivalent, key selection considerations include its 144-pin LFQFP package, 160-MHz GPTW/MTU3 timer subsystem with 195-ps HRPWM resolution, IEC60730-compliant safety features (CAC, CRCA, IWDT, RAM test assist), and dual 12-bit A/D converters supporting simultaneous sampling across 30 channels.

Technical Context

The R5F566TAEGFN#30 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111-instruction set including DSP extensions. Its clock system supports PLL multiplication using 8–24 MHz external crystals or internal 16–20 MHz HOCO, delivering synchronized ICLK (160 MHz), PCLKA (120 MHz), PCLKB/C/D (up to 160/60 MHz), and BCLK (40 MHz) domains.

Peripheral integration centers on deterministic real-time control: 10-channel 32-bit GPTW with dead-time generation and ELC-triggered A/D start, 9-channel 16-bit MTU3d for 3-phase inverter timing, 6-channel analog comparator with programmable gain amplifier inputs, and TSIP-Lite encryption engine supporting AES-128/256 in GCM/CBC modes for secure firmware updates.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAEGFN#30?

The R5F566TAEGFN#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects real-world execution speed of the RXv3 CPU core with its 111-instruction set, single-cycle execution capability, and integrated 32-bit multiplier/divider - critical for fast FOC loop computation in motor control applications.

Does the R5F566TAEGFN#30 support simultaneous sampling across all 30 ADC channels?

No - the R5F566TAEGFN#30 supports simultaneous sampling only within each of its three independent 12-bit S12ADH units: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). While all 30 channels can be scanned in coordinated sequence, true simultaneous sampling is limited to the 8+8 channel pairs across Units 0 and 1, with Unit 2 operating independently.

What safety certifications or functional safety features does the R5F566TAEGFN#30 include?

The R5F566TAEGFN#30 includes hardware-accelerated IEC60730 Class B compliance features: Clock Accuracy Measurement Circuit (CAC), CRC Calculator (CRCA), Independent Watchdog Timer (IWDT) with window function, Data Operation Circuit (DOC) for RAM testing, and register write protection. These eliminate need for external safety monitors in industrial inverter designs.

Can the R5F566TAEGFN#30 generate 5-phase complementary PWM waveforms?

Yes - the R5F566TAEGFN#30's 32-bit GPTW timer supports 5-phase complementary PWM mode using two output channels, enabling direct control of 5-phase stepper or BLDC motors. This mode provides non-overlapping outputs with programmable dead time and synchronized start/stop across all phases via ELC triggering.

What is the resolution and timing precision of the High-Resolution PWM (HRPWM) in the R5F566TAEGFN#30?

The R5F566TAEGFN#30 delivers 195 ps minimum timing resolution on its 4-channel HRPWM subsystem, which extends the GPTW timer outputs. This precision is achieved at 160 MHz operation and enables sub-nanosecond dead-time control - essential for minimizing shoot-through in SiC/GaN-based inverter stages.
