Renesas R5F572TFGGFB#30

Overview

R5F572TFGGFB#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, 2-channel 12-bit D/A, CAN 2.0B, full-speed USB 2.0, and TSIP-Lite encryption - all in a 144-pin LFQFP package rated for –40°C to +105°C operation.

For engineers reviewing the R5F572TFGGFB#30 datasheet, R5F572TFGGFB#30 pinout, R5F572TFGGFB#30 application, or R5F572TFGGFB#30 equivalent, key selection considerations include its 10-channel GPTW timer supporting 3-phase/5-phase complementary PWM, ELC-driven event-triggered peripheral coordination without CPU intervention, IEC60730 safety features (oscillation-stop detection, RAM test assist, CRC, self-diagnostic ADC), and 5-V-tolerant I/O for robust industrial interfacing.

Technical Context

The R5F572TFGGFB#30 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 1160 CoreMark @ 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 PCLKA (up to 120 MHz), PCLKB (60 MHz), PCLKC (200 MHz for MTU3/GPTW counters), and PCLKD (60 MHz for ADC) domains.

Motor control execution relies on tightly coupled peripherals: GPTW timers synchronized to PCLKC for sub-nanosecond PWM edge placement, HRPWM overlay for 195 ps fine timing adjustment, ELC for hardware-triggered ADC start and dead-time compensation, and POE3B/POEG for hardware-initiated output disable during overcurrent or comparator fault events - enabling deterministic, low-latency inverter protection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572TFGGFB#30?

The R5F572TFGGFB#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 FPU, and 8-Kbyte ROM cache - enabling deterministic execution of complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) in real time. The R5F572TFGGFB#30 sustains this throughput across its full temperature range (–40°C to +105°C).

Does the R5F572TFGGFB#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F572TFGGFB#30 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection for main clock, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, independent watchdog timer (IWDT), and register write protection. These are documented in the R01DS0331EJ0110 datasheet and eliminate the need for external safety monitors when properly configured - significantly reducing system-level validation effort for the R5F572TFGGFB#30.

How many analog-to-digital converter channels does the R5F572TFGGFB#30 support, and what is their sampling capability?

The R5F572TFGGFB#30 integrates three 12-bit S12ADH units totaling 30 input channels: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). It supports simultaneous sampling across all three units, with built-in sample-and-hold circuits on six channels (3 per unit) and programmable gain amplifiers for pseudo-differential inputs. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK - enabling high-fidelity current/voltage capture for dual-shunt FOC implementations using the R5F572TFGGFB#30.

What PWM resolution and channel count does the R5F572TFGGFB#30 provide for motor control?

The R5F572TFGGFB#30 provides 10 channels of 32-bit General PWM Timer (GPTW) with hardware dead-time insertion and 4 channels of High-Resolution PWM (HRPWM) offering a minimum timing resolution of 195 ps. GPTW supports single-phase, 3-phase, and 5-phase complementary PWM modes; HRPWM overlays GPTW outputs to adjust rising/falling edges at sub-nanosecond granularity. This combination enables precise gate timing for SiC/GaN inverters and eliminates software-based dead-time compensation in the R5F572TFGGFB#30.

Is the R5F572TFGGFB#30 pin-compatible with other RX72T group MCUs?

No, the R5F572TFGGFB#30 is not pin-compatible with other RX72T variants due to its 144-pin LFQFP (PLQP0144KA-B) package - whereas alternatives like R5F572MFDDFB#30 use 100-pin LFQFP. While electrical and functional compatibility exists within the RX72T family (same peripheral registers, memory map, and instruction set), PCB layout must be redesigned for the R5F572TFGGFB#30 due to differing pin count, power/ground distribution, and peripheral pin assignments. Always verify pinout against the R01DS0331EJ0110 datasheet for the R5F572TFGGFB#30.
