Renesas R5F572TFCDFB#30

Overview

R5F572TFCDFB#30 from Renesas is a 32-bit RXv3 microcontroller optimized for industrial motor control, featuring a 200 MHz CPU core, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, 32 Kbytes data flash, and integrated high-resolution PWM (195 ps min. resolution) for precise inverter gate timing. It integrates dual 12-bit A/D converters with simultaneous sampling across 30 channels, 6-channel analog comparators, CAN 2.0B, full-speed USB 2.0 host/function/OTG, and TSIP-Lite encryption for IEC 60730-compliant safety-critical drives.

For engineers reviewing the R5F572TFCDFB#30 datasheet, R5F572TFCDFB#30 pinout, R5F572TFCDFB#30 application, or R5F572TFCDFB#30 equivalent, key selection criteria include 200 MHz real-time PWM timing accuracy, 3-phase/5-phase complementary PWM support with dead-time control, simultaneous 12-bit ADC sampling across three units, integrated CAN and USB for motion control networking, and hardware-based AES-128/256 for secure firmware updates and runtime integrity verification.

Technical Context

The R5F572TFCDFB#30 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 1160 CoreMark @ 200 MHz, and register bank save for fast interrupt response. Its clock system supports PLL multiplication of 8–24 MHz external crystals or 16–20 MHz HOCO, enabling independent PCLKC up to 160 MHz for HRPWM and 200 MHz for GPTW counter reference.

Motor control execution relies on tightly coupled peripherals: ELC enables event-triggered timer starts/stops without CPU intervention; MTU3d provides 9-channel 16-bit timers with 3-phase complementary PWM and dead-time compensation; GPTW delivers 10-channel 32-bit PWM with synchronous start/clear and frame-interval interrupts; HRPWM overlays 195 ps edge timing control on GPTW0–GPTW3 outputs.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572TFCDFB#30?

The R5F572TFCDFB#30 operates at a maximum frequency of 200 MHz and achieves 1160 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32×32→64-bit multiplier, and IEEE 754-compliant FPU - enabling deterministic execution of complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) within tight timing budgets.

Does the R5F572TFCDFB#30 support simultaneous sampling across all 30 A/D converter channels?

No - the R5F572TFCDFB#30 supports simultaneous sampling only across the three independent S12ADH units: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). While all 30 channels share the same 12-bit resolution and 0.9 µs minimum conversion time, true simultaneous sampling is limited to up to 7 channels per unit in scan mode, with inter-unit synchronization achievable via ELC-triggered start signals. This architecture enables coordinated current/voltage acquisition critical for three-phase motor control.

What safety certifications and self-test features does the R5F572TFCDFB#30 provide for IEC 60730 compliance?

The R5F572TFCDFB#30 includes multiple IEC 60730 Class B support features: oscillation-stoppage detection for main clock, RAM test-assisting function using DOC, CRC calculator (CRCA) for memory integrity, independent watchdog timer (IWDT) with windowing, clock frequency accuracy measurement circuit (CAC), and register write protection. These are documented in Renesas Application Note R01AN3913JJ0100 and enable streamlined functional safety certification for motor control applications without requiring external safety monitors.

Can the R5F572TFCDFB#30 operate with a 5 V supply, and what I/O voltage tolerance does it support?

Yes - the R5F572TFCDFB#30 operates from a single 2.7–5.5 V supply and supports 5-V tolerant I/O on four dedicated pins (VCC_IO = 5 V compatible). Its general-purpose I/O ports include 110 pins with programmable pull-up resistors, open-drain capability, and selectable driving strength. This 5-V tolerance allows direct interfacing with legacy industrial sensors, encoders, and logic circuits without level-shifting components.

What is the role of the Event Link Controller (ELC) in motor control applications using the R5F572TFCDFB#30?

The Event Link Controller (ELC) in the R5F572TFCDFB#30 enables autonomous peripheral interaction without CPU intervention - for example, triggering GPTW PWM start upon MTU3d timer overflow, initiating ADC conversion at precise PWM center points, or asserting comparator interrupt to disable outputs via POE3B. With 188 internal event sources and configurable routing, the ELC reduces CPU load by >40% in real-time motor control loops and ensures sub-microsecond timing determinism between critical events.
