Renesas R5F566TAADFP#30

Overview

R5F566TAADFP#30 from Renesas is a 32-bit RXv3 core MCU operating at up to 160 MHz, delivering 928 CoreMark performance. It integrates 1 MB code flash, 128 KB SRAM (no wait states), 32 KB data flash (100,000 erase/write cycles), dual 12-bit DACs, six-channel analog comparators, and a 12-bit A/D converter with three units totaling 30 channels. It targets motor control systems requiring high-resolution PWM generation and IEC60730-compliant safety functions.

For engineers reviewing the R5F566TAADFP#30 datasheet, R5F566TAADFP#30 pinout, R5F566TAADFP#30 application, or R5F566TAADFP#30 equivalent, key selection criteria include its 144-pin LFQFP package, 160-MHz GPTW/HRPWM timing resolution (195 ps minimum), integrated CAN 2.0B interface, full-speed USB 2.0 host/function capability, and support for IEC60730 self-test features including oscillation-stop detection and RAM test assistance.

Technical Context

The R5F566TAADFP#30 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111 instructions including DSP extensions. Its clock system supports PLL multiplication using either an external 8–24 MHz crystal or internal 16/18/20 MHz HOCO as reference, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

It features event-driven architecture via the Event Link Controller (ELC), allowing direct inter-module triggering without CPU intervention-critical for deterministic motor control. Safety is reinforced by Trusted Secure IP Lite (AES-128/256, TRNG), MPU with eight protection areas, register write protection, and dedicated hardware for CAC, CRCA, and DOC-based diagnostics.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAADFP#30?

The R5F566TAADFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficiency in executing integer workloads typical of motor control firmware. The R5F566TAADFP#30 sustains this speed across its full memory map with zero wait states on SRAM and optimized flash access via ROM cache hit behavior.

Does the R5F566TAADFP#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TAADFP#30 includes hardware-accelerated features required for IEC60730 Class B certification: oscillation-stop detection, clock frequency accuracy measurement (CAC), CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, and register write protection. These capabilities are documented in Renesas Application Note R01AN5015JJ0100 and reduce software validation effort for safety-critical appliance control.

What package type and pin count does the R5F566TAADFP#30 use?

The R5F566TAADFP#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with 20 × 20 mm body size and 0.5 mm pitch (PLQP0144KA-B). It provides 110 general-purpose I/O pins, including 4 with 5-V tolerance, and supports full peripheral mapping including all 10 GPTW channels, 30 ADC inputs, and dual CAN/USB interfaces.

Can the R5F566TAADFP#30 generate 3-phase complementary PWM waveforms with programmable dead time?

Yes, the R5F566TAADFP#30 supports 3-phase complementary PWM in both GPTW (10-channel) and MTU3d (9-channel) modules. GPTW allows automatic dead-time insertion with user-defined delay values, while MTU3d provides hardware-enforced non-overlapping outputs and synchronous clearing-enabling robust inverter gate drive without software intervention.

What is the resolution and timing precision of the high-resolution PWM (HRPWM) in the R5F566TAADFP#30?

The HRPWM in the R5F566TAADFP#30 achieves a minimum timing resolution of 195 ps when operating at 160 MHz. This applies to GPTW0–GPTW3 outputs and enables sub-nanosecond edge placement for ultra-precise dead-time control in SiC/GaN-based inverters. The feature is implemented in dedicated hardware and does not rely on software interpolation or timer overruns.
