FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBDGFL#50?

The R5F526TBDGFL#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This score reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter. The R5F526TBDGFL#50 sustains this performance with no-wait access to both 512 KB code flash and 64 KB SRAM at full speed.

Does the R5F526TBDGFL#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBDGFL#50 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps. It includes dedicated message RAM, error counters, and bit-rate switching logic. The R5F526TBDGFL#50 uses this interface for real-time diagnostics and parameter exchange in motor drive systems.

What ADC configuration does the R5F526TBDGFL#50 provide, and how many simultaneous sampling channels are supported?

The R5F526TBDGFL#50 includes two 12-bit S12ADH ADC units: Unit 0 (7 channels with 3 sample-and-hold circuits) and Unit 2 (8 channels). It supports simultaneous sampling across up to 6 channels (3 per S&H unit), enabling synchronized current and voltage acquisition for field-oriented control. The R5F526TBDGFL#50 achieves 0.9 µs minimum conversion time at 60 MHz ADCLK.

What is the HRPWM resolution of the R5F526TBDGFL#50, and which timers feed into it?

The R5F526TBDGFL#50 provides 4-channel High-Resolution PWM (HRPWM) with a minimum timing resolution of 260 ps when operating at 120 MHz. This capability applies exclusively to GPTW0 through GPTW3 outputs. The R5F526TBDGFL#50 uses HRPWM to achieve sub-nanosecond edge placement for dead-time optimization in SiC/GaN-based inverters.

Is the R5F526TBDGFL#50 qualified for industrial temperature range, and what package type does it use?

Yes, the R5F526TBDGFL#50 is rated for –40°C to +105°C (G-version), meeting industrial temperature requirements. It is packaged in PLQP0100KB-B - a 100-pin LFQFP with 14 mm × 14 mm body, 0.5 mm pitch, and exposed thermal pad. This package supports high-power motor control thermal dissipation and is compatible with standard reflow profiles.
