Renesas R5F572TFADFP#30

Overview

R5F572TFADFP#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 minimum 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 interface, full-speed USB 2.0 host/function/OTG, and TSIP-Lite encryption for IEC 60730-compliant safety-critical drives.

For engineers reviewing the R5F572TFADFP#30 datasheet, R5F572TFADFP#30 pinout, R5F572TFADFP#30 application, or R5F572TFADFP#30 equivalent, this MCU delivers deterministic real-time performance for servo and vector-controlled AC/BLDC motors, with ELC-driven event chaining to minimize CPU intervention during PWM-triggered ADC sampling and fault response.

Technical Context

The R5F572TFADFP#30 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 1160 CoreMark at 200 MHz, and register bank save for fast context switching in interrupt-heavy motor control loops. Its clock system supports PLL multiplication of 8–24 MHz crystal or 16–20 MHz HOCO inputs, with independent PCLKC up to 160 MHz for HRPWM timing and PCLKA up to 120 MHz for GPTW/MTU3 operation.

It features three synchronized 12-bit A/D units (S12ADH) supporting simultaneous sampling across 30 channels, programmable gain amplifiers on six channels for pseudo-differential current sensing, and hardware-accelerated trigonometric functions (TFU) for field-oriented control. Safety mechanisms include CAC for clock accuracy monitoring, CRCA for CRC-32/8, LVDA voltage detection, and register write protection aligned with IEC 60730 Class B requirements.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572TFADFP#30?

The R5F572TFADFP#30 operates at a maximum frequency of 200 MHz and achieves 1160 CoreMark when running at that speed. This performance stems from its RXv3 CPU core with 32-bit multiplier, barrel shifter, and single-cycle instruction execution at 200 MHz - enabling deterministic execution of complex motor control algorithms without pipeline stalls or cache misses under real-time constraints.

Does the R5F572TFADFP#30 support simultaneous sampling across all 30 A/D channels?

No, the R5F572TFADFP#30 supports simultaneous sampling across up to 7 channels per A/D unit, with three independent 12-bit S12ADH units (Unit 0: 8 channels, Unit 1: 8 channels, Unit 2: 14 channels). Units 0 and 1 each include three sample-and-hold circuits, allowing true simultaneous capture of three-phase current and DC bus voltage - critical for accurate field-oriented control without inter-channel skew.

What PWM resolution does the R5F572TFADFP#30 provide, and at what clock speed is it achieved?

The R5F572TFADFP#30 delivers a minimum PWM resolution of 195 ps using its High-Resolution PWM (HRPWM) module, which operates with PCLKC up to 160 MHz. This resolution applies specifically to GPTW0–GPTW3 outputs and enables nanosecond-level dead-time control - essential for preventing shoot-through in high-frequency SiC/GaN inverter designs while maintaining thermal stability across temperature variations.

Is the R5F572TFADFP#30 qualified for IEC 60730 Class B compliance?

Yes, the R5F572TFADFP#30 includes multiple hardware features required for IEC 60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement (CAC), CRC calculator (CRCA), independent watchdog timer (IWDT), RAM test-assisting function via DOC, and register write protection. These are documented in the R01DS0331EJ0110 datasheet and enable certified self-test routines without software overhead.

What package type and temperature grade does the R5F572TFADFP#30 use?

The R5F572TFADFP#30 uses the PLQP0144KA-B package: a 144-pin LFQFP with 20 × 20 mm body and 0.5 mm pitch. It is rated for the G-version industrial temperature range of –40°C to +105°C, making it suitable for under-hood motor control units and high-ambient industrial enclosures where thermal derating must be minimized.
