Renesas R5F572TFCGFB#10

Overview

R5F572TFCGFB#10 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 R5F572TFCGFB#10 datasheet, R5F572TFCGFB#10 pinout, R5F572TFCGFB#10 application, or R5F572TFCGFB#10 equivalent, key selection criteria include its 200 MHz real-time PWM timing capability, IEC60730-compliant safety features (oscillation detection, RAM test assist, CRC, register write protection), 5-V-tolerant I/O support, and integrated HRPWM/MTU3/GPTW co-ordination for 3-phase/5-phase motor drive systems.

Technical Context

The R5F572TFCGFB#10 implements the RXv3 CPU core with single-cycle instruction execution at 200 MHz, IEEE 754-compliant FPU, and 16 register banks for fast context switching. Its clock system supports PLL multiplication of 8–24 MHz crystal or 16–20 MHz HOCO inputs, with independent PCLKA (120 MHz), PCLKC (200 MHz for GPTW/MTU3 counters), and PCLKD (60 MHz for A/D) domains enabling concurrent high-speed peripheral operation without CPU bottlenecks.

Safety-critical operation is enabled by dedicated hardware: the CAC measures clock accuracy against reference sources, the IWDT uses a 120-kHz dedicated oscillator with windowed refresh, the CRCA computes configurable 8-/32-bit CRCs, and the ELC links 188 internal events (e.g., timer overflows, comparator triggers) to initiate peripheral actions - including A/D conversion starts and PWM dead-time compensation - without CPU intervention.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F572TFCGFB#10?

The R5F572TFCGFB#10 operates at a maximum frequency of 200 MHz using the 32-bit RXv3 CPU core. It delivers 1160 CoreMark performance and includes a single-precision IEEE 754 floating-point unit (FPU), 16 register banks for fast context save/restore, and support for little-endian or big-endian data arrangement. This architecture enables deterministic execution of complex motor control algorithms such as field-oriented control (FOC) within strict timing budgets.

Does the R5F572TFCGFB#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F572TFCGFB#10 includes dedicated hardware for IEC60730 Class B compliance: clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with windowed refresh, oscillation-stop detection, CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, and register write protection. These features are documented in the R01DS0331EJ0110 datasheet and reduce external component count and software validation effort for safety-critical motor control applications.

What PWM capabilities does the R5F572TFCGFB#10 offer for motor control?

The R5F572TFCGFB#10 provides three complementary PWM subsystems: 10-channel 32-bit GPTW timers, 9-channel 16-bit MTU3d, and 4-channel high-resolution HRPWM with 195 ps minimum timing resolution. It supports single-phase, 3-phase, and 5-phase complementary PWM modes with hardware dead-time insertion, synchronous start/stop, and ELC-triggered updates - enabling precise gate timing for SiC/GaN inverters in servo drives and EV chargers.

How many analog-to-digital converter channels does the R5F572TFCGFB#10 have, and what is their sampling capability?

The R5F572TFCGFB#10 integrates a 30-channel 12-bit S12ADH A/D converter with three independent sample-and-hold circuits (8+8+14 channels). It supports simultaneous sampling across all channels with a minimum conversion time of 0.9 µs per channel at 60 MHz ADCLK, and includes programmable gain amplifiers (6 channels) for pseudo-differential input - essential for high-fidelity current and voltage sensing in motor control loops.

What package type and pin count does the R5F572TFCGFB#10 use, and is it RoHS compliant?

The R5F572TFCGFB#10 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch, and is RoHS compliant. This package supports 110 general-purpose I/O pins with 5-V tolerance, open-drain capability, and programmable pull-up resistors - matching the full-featured RX72T variant with PGA pseudo-differential input and USB functionality as specified in the R01DS0331EJ0110 datasheet.
