Renesas R5F572TKBGFP#30

Overview

R5F572TKBGFP#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 ADC units with pseudo-differential PGA inputs, 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 R5F572TKBGFP#30 datasheet, R5F572TKBGFP#30 pinout, R5F572TKBGFP#30 application, or R5F572TKBGFP#30 equivalent, this MCU delivers deterministic real-time control for servo and BLDC motor systems requiring simultaneous sampling, multi-phase complementary PWM, hardware event linking (ELC), and functional safety support including oscillation-stop detection, RAM ECC, and CRC acceleration.

Technical Context

The R5F572TKBGFP#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. Its clock system supports PLL multiplication using 8–24 MHz external crystals or 16/18/20 MHz HOCO, with independent PCLK domains enabling concurrent operation of GPTW (PCLKC up to 160 MHz) and MTU3 (PCLKA up to 120 MHz).

Motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW with dead-time generation and synchronous start/stop, 9-channel 16-bit MTU3d for 3-phase PWM, 4-channel HRPWM for sub-nanosecond edge placement, and ELC-driven trigger chaining between timers, ADCs, and comparators-eliminating CPU intervention during critical waveform sequencing.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572TKBGFP#30?

The R5F572TKBGFP#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 single-cycle instruction execution, on-chip 32-bit multiplier/divider, and optional 8-Kbyte ROM cache - enabling fast execution of motor control algorithms such as field-oriented control and space-vector modulation without external acceleration.

Does the R5F572TKBGFP#30 support simultaneous sampling across multiple ADC channels?

Yes, the R5F572TKBGFP#30 supports true simultaneous sampling using three independent 12-bit S12ADH units: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This allows concurrent acquisition of three-phase motor currents and DC bus voltage with zero inter-channel skew - essential for accurate current reconstruction in high-bandwidth FOC loops.

What PWM resolution and complementary output capabilities does the R5F572TKBGFP#30 provide?

The R5F572TKBGFP#30 delivers 195 ps minimum edge placement resolution via its HRPWM circuit applied to GPTW0–GPTW3 channels. It supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes with automatic dead-time insertion - all configurable through hardware registers without CPU intervention, ensuring reliable inverter gate timing even under heavy interrupt load.

How does the R5F572TKBGFP#30 support IEC 60730 functional safety compliance?

The R5F572TKBGFP#30 includes dedicated hardware for IEC 60730 Class B: main clock oscillation-stop detection, clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, RAM test assist via DOC, CRC calculator (CRCA), and register write protection. These features enable automated self-tests and fault detection - reducing software validation scope and accelerating certification for industrial motor drives.

What communication interfaces are integrated into the R5F572TKBGFP#30?

The R5F572TKBGFP#30 integrates CAN 2.0B (32 mailboxes), full-speed USB 2.0 host/function/OTG, one RIIC channel (400 kbps SMBus-compatible), one RSPI channel (30 Mbps), seven SCI channels (including LIN-capable SCIh), and an external bus interface. This combination supports drive commissioning via USB, real-time diagnostics over CAN, and sensor interfacing via I²C/SPI - all without external protocol translators.
