FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBBDFP#30?

The R5F526TBBDFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 16 general-purpose 32-bit registers, and integrated FPU-making it suitable for computationally intensive motor control algorithms such as field-oriented control (FOC) and sensorless estimation running directly on the R5F526TBBDFP#30.

Does the R5F526TBBDFP#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBBDFP#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables high-speed communication (up to 5 Mbps data phase) between motor controllers, PLCs, and HMIs in industrial networks. The R5F526TBBDFP#30's CAN FD implementation includes message filtering, FIFO buffering, and error handling-critical for deterministic real-time control in distributed drive systems.

What PWM resolution and complementary output capabilities does the R5F526TBBDFP#30 provide for inverter gate driving?

The R5F526TBBDFP#30 delivers 260 ps minimum timing resolution via its HRPWM circuit applied to GPTWa outputs, enabling precise dead-time tuning for SiC/GaN power stages. It supports 3-phase complementary PWM (via MTU3d), 5-phase complementary PWM (via GPTWa), and 10-channel single-phase complementary PWM-all with automatic dead-time insertion, synchronous start/stop, and fault-driven output disable. These features are fully implemented in the R5F526TBBDFP#30 for robust inverter control.

How does the R5F526TBBDFP#30 meet IEC60730 Class B safety requirements?

The R5F526TBBDFP#30 includes multiple hardware-based IEC60730 Class B compliance features: oscillation-stop detection for main clock failure, RAM test assist using DOC, CRCA for data integrity, register write protection, and self-diagnostic functions for ADC disconnection and clock accuracy measurement. These capabilities are built into the silicon of the R5F526TBBDFP#30 and require no external components-reducing bill-of-materials and simplifying certification for motor control applications.

What is the package type and pin count of the R5F526TBBDFP#30?

The R5F526TBBDFP#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package (LFQFP) with 14 × 14 mm body size and 0.5 mm pitch. It provides 82 general-purpose I/O pins, two 5-V tolerant inputs, and dedicated pins for power, reset, clock, and high-speed peripherals-including MTU3d and GPTWa PWM outputs. This package is specified for the R5F526TBBDFP#30 and supports industrial temperature range (–40°C to +85°C).
