The R5F526TFCGFL#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It achieves 709 CoreMark performance and supports single-cycle instruction execution, IEEE 754-compliant floating-point operations, and 113 instructions including DSP extensions. The R5F526TFCGFL#30 uses a linear 4-Gbyte address space and includes two 72-bit accumulators for high-precision motor control math.

Does the R5F526TFCGFL#30 support IEC60730 Class B compliance for household appliances?

Yes, the R5F526TFCGFL#30 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection, self-diagnostic A/D converter, RAM test assistance via DOC, CRC calculator (CRCA), independent watchdog timer (IWDTa) with window function, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and validated for use in certified appliance control designs.

What PWM capabilities does the R5F526TFCGFL#30 provide for 3-phase motor control?

The R5F526TFCGFL#30 provides three complementary PWM subsystems: MTU3d (9-channel, 16-bit) for basic 3-phase output, GPTWa (8-channel, 32-bit) for flexible waveform generation, and HRPWM (4-channel) enabling 260 ps minimum timing resolution on GPTW0–GPTW3 outputs. Combined with POE3D, it supports automatic fault shutdown, dead-time insertion, and synchronous start/stop across all channels - essential for inverter leg control in PMSM/BLDC drives.

How many analog-to-digital converter channels does the R5F526TFCGFL#30 support, and what is their resolution?

The R5F526TFCGFL#30 supports 23 total channels across three 12-bit S12ADH ADC units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), all with sample-and-hold circuitry. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz. The R5F526TFCGFL#30 also includes programmable gain amplifiers on Units 0 and 1 for direct current-sensing amplifier interface.

What package type and pin count does the R5F526TFCGFL#30 use?

The R5F526TFCGFL#30 uses the PLQP0100KB-B package: a 100-pin LQFP measuring 14 × 14 mm with 0.5 mm pitch. It provides up to 82 general-purpose I/O pins, including 2 pins with 5-V tolerance, 15 large-current output pins, and dedicated signals for CAN FD, multiple SCI/RSCI interfaces, and motor control peripherals. This matches the highest-pin-count variant of the RX26T Group.
