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, and TSIP-Lite encryption - deployed in servo drives and PMSM/BLDC motor controllers.

For engineers reviewing the R5F572TKEGFP#10 datasheet, R5F572TKEGFP#10 pinout, R5F572TKEGFP#10 application, or R5F572TKEGFP#10 equivalent, key selection criteria include its 144-pin LFQFP package with 110 GPIOs (4× 5-V tolerant), 10-channel GPTW + 4-channel HRPWM for multi-phase inverter control, IEC60730-compliant safety features (IWDT, CAC, CRCA, RAM test assist), and support for simultaneous sampling across three 12-bit ADC units.

Technical Context

The R5F572TKEGFP#10 implements the RXv3 CPU core with single-cycle instruction execution at 200 MHz, IEEE 754-compliant FPU, 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 peripheral clocks (PCLKA up to 120 MHz, PCLKC up to 200 MHz for timers, PCLKD up to 60 MHz for ADC).

Motor control is enabled by tightly coupled peripherals: GPTW channels synchronized to PCLKC for sub-nanosecond PWM edge placement, ELC-driven event chaining between MTU3, GPTW, and S12ADH for zero-CPU-overhead waveform generation and synchronized sampling, and POE3B/POEG hardware protection logic for immediate output disable during overcurrent or comparator fault detection.

FAQ

What is the maximum operating frequency and core architecture of the R5F572TKEGFP#10?

The R5F572TKEGFP#10 operates at a maximum frequency of 200 MHz using the 32-bit RXv3 CPU core. This core supports single-cycle instruction execution, IEEE 754-compliant floating-point operations, and 113 instructions including DSP extensions. Its 200 MHz speed enables sub-microsecond execution of field-oriented control (FOC) loops - a requirement for high-bandwidth servo applications. The R5F572TKEGFP#10 achieves 1160 CoreMark at this frequency, confirming deterministic real-time performance.

Does the R5F572TKEGFP#10 support simultaneous sampling across multiple ADC channels?

Yes, the R5F572TKEGFP#10 integrates three independent 12-bit S12ADH ADC units (totaling 30 channels) with hardware-triggered simultaneous sampling capability across up to seven channels. This is achieved using shared ELC-triggered start signals routed to all three units, ensuring phase-aligned acquisition of motor phase currents and DC-link voltage - essential for accurate vector control calculations. The R5F572TKEGFP#10's simultaneous sampling eliminates inter-channel skew, maintaining timing coherence critical for FOC accuracy.

What PWM resolution and channel count does the R5F572TKEGFP#10 provide for motor control?

The R5F572TKEGFP#10 delivers 10-channel 32-bit General PWM Timer (GPTW) plus 4-channel High-Resolution PWM (HRPWM) with a minimum resolution of 195 ps at 160 MHz PCLKC. GPTW supports single-phase, 3-phase, and 5-phase complementary PWM modes with automatic dead-time insertion. HRPWM overlays fine timing control on GPTW0–GPTW3 outputs, enabling sub-nanosecond edge placement for precise dead-time compensation and reduced torque ripple. This combination makes the R5F572TKEGFP#10 uniquely suited for high-fidelity inverter gate driving.

How does the R5F572TKEGFP#10 support IEC60730 functional safety compliance?

The R5F572TKEGFP#10 includes multiple hardware features certified for IEC60730 Class B compliance: an independent watchdog timer (IWDT) with dedicated 120 kHz oscillator, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, oscillation-stop detection, and register write protection. These features enable self-test routines and fault detection without software overhead. The R5F572TKEGFP#10's integrated safety mechanisms reduce external component count and simplify certification - a key advantage over general-purpose MCUs requiring discrete safety monitors.

What package type and pin count does the R5F572TKEGFP#10 use, and what are its key I/O characteristics?

The R5F572TKEGFP#10 uses a 144-pin LFQFP package (PLQP0144KA-B, 20 × 20 mm, 0.5 mm pitch) with 110 general-purpose I/O pins. Key I/O features include 4× 5-V tolerant inputs for industrial-level signal interfacing, configurable pull-up resistors on all GPIOs, open-drain capability, and 15 high-current output pins. The package supports full peripheral access - including USB, CAN, multiple SCI interfaces, and all 10 GPTW/4 HRPWM output pins - making it ideal for complex motor control boards where signal routing density and mixed-voltage interoperability are critical. The R5F572TKEGFP#10's pinout is optimized for noise isolation between analog, power, and digital domains.
