Renesas R5F566TAADFH#30

Overview

R5F566TAADFH#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 generation with 195 ps timing resolution. It integrates dual 12-bit ADC units with pseudo-differential PGA inputs, 6-channel analog comparators, CAN 2.0B interface, full-speed USB 2.0 host/function/OTG, and TSIP-Lite encryption for IEC 60730-compliant safety-critical systems.

For engineers reviewing the R5F566TAADFH#30 datasheet, R5F566TAADFH#30 pinout, R5F566TAADFH#30 application, or R5F566TAADFH#30 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across 30 ADC channels, hardware-accelerated PWM dead-time compensation, ELC-triggered peripheral coordination without CPU intervention, and robust functional safety features including oscillation-stop detection, RAM ECC, and register write protection.

Technical Context

The R5F566TAADFH#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 4-Gbyte linear address space. Its clock system supports PLL multiplication using either an external 8–24 MHz crystal or internal 16/18/20 MHz HOCO, enabling independent domain clocks: ICLK up to 160 MHz for CPU, PCLKA up to 120 MHz for GPTW/MTU3/HRPWM, PCLKB up to 60 MHz for most peripherals, and PCLKD up to 60 MHz for S12ADH.

Real-time motor control is enabled by tightly coupled timer subsystems: ten 32-bit GPTW channels with synchronous start/stop and dead-time generation, nine 16-bit MTU3d channels supporting 3-phase complementary PWM, and four HRPWM channels delivering 195 ps minimum edge placement resolution. All timers synchronize to PCLKC (up to 160 MHz) and interoperate via the Event Link Controller (ELC) to trigger ADC conversions, comparator events, or port output disables without software overhead.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAADFH#30?

The R5F566TAADFH#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance under benchmark conditions. This reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and integrated 32-bit multiplier/divider-enabling deterministic real-time response in motor control loops without software overhead.

Does the R5F566TAADFH#30 support simultaneous sampling across multiple ADC channels?

Yes, the R5F566TAADFH#30 integrates three independent 12-bit S12ADH units (totaling 30 channels), with Units 0 and 1 each providing three sample-and-hold circuits. This allows truly simultaneous sampling of up to seven analog signals-critical for accurate current reconstruction in three-phase motor control applications.

What PWM resolution and complementary output capabilities does the R5F566TAADFH#30 provide?

The R5F566TAADFH#30 delivers 195 ps minimum edge placement resolution via its four HRPWM channels linked to GPTW0–GPTW3, and supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes. Hardware dead-time insertion and phase-shift compensation eliminate software timing jitter in inverter gate drive signals.

How does the R5F566TAADFH#30 support IEC 60730 functional safety compliance?

The R5F566TAADFH#30 includes dedicated hardware for IEC 60730 Class B: main clock oscillation-stop detection, ADC input disconnection check, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assist function (DOC), and register write protection. These features enable self-test routines and fault detection without external supervision.

What package type and pin count does the R5F566TAADFH#30 use?

The R5F566TAADFH#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with PLQP0144KA-B footprint: 20 mm × 20 mm body, 0.5 mm lead pitch, and exposed thermal pad. It provides 110 general-purpose I/O pins-including 4 with 5-V tolerance-optimized for high-density motor control PCB layouts.
