FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9AGFL#30?

The R5F526T9AGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and optimized memory subsystem-enabling real-time motor control loop execution within strict timing budgets. The R5F526T9AGFL#30 sustains full 120 MHz operation across its 512 KB flash and 64 KB SRAM with no wait states.

Does the R5F526T9AGFL#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9AGFL#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), self-diagnostic ADC/comparator functions, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and require no external components-making the R5F526T9AGFL#30 suitable for safety-critical appliance and industrial control applications.

What PWM resolution does the R5F526T9AGFL#30 achieve, and how is it used in motor control?

The R5F526T9AGFL#30 achieves a minimum PWM timing resolution of 260 ps via its 4-channel HRPWM peripheral, synchronized to the 32-bit GPTWa timers running at 120 MHz. This enables precise dead-time adjustment and gate-drive timing calibration in SiC/GaN-based inverters-reducing shoot-through risk and improving thermal efficiency. The R5F526T9AGFL#30 uses this capability in 3-phase and 5-phase complementary PWM modes for high-fidelity motor vector control.

How many ADC channels does the R5F526T9AGFL#30 support, and what sampling architecture does it use?

The R5F526T9AGFL#30 supports 22 total 12-bit ADC channels distributed across three sample-and-hold units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It enables true simultaneous sampling across all three units-critical for capturing instantaneous current and voltage waveforms in 3-phase motor control. The R5F526T9AGFL#30 uses hardware-triggered conversion (e.g., from MTU/GPTW) with configurable sampling time per channel and digital comparison for overcurrent detection.

What communication interfaces are integrated into the R5F526T9AGFL#30, and which support CAN FD?

The R5F526T9AGFL#30 integrates CAN FD (ISO11898-1:2015 compliant, 1 channel), 4× SCI, 3× RSCI (with Manchester encoding and HBS), 1× RIIC (400 kbps I²C/SMBus), 1× RI3C (I3C SDR), and 2× RSPI (30 Mbps). Only the dedicated CANFD module supports CAN FD-providing high-bandwidth, deterministic messaging for motor control networks. All other interfaces operate independently and can be linked via the Event Link Controller (ELC) for autonomous peripheral coordination.
