For engineers reviewing the R5F526TFCDFP#10 datasheet, R5F526TFCDFP#10 pinout, R5F526TFCDFP#10 application, or R5F526TFCDFP#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526TFCDFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in interrupt-heavy motor control loops. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - all configurable via register-based frequency division/multiplication for independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at lower rates).

Peripheral coordination is managed by the Event Link Controller (ELC), which enables 183 internal event signals to trigger timer starts/stops, A/D conversions, or PWM dead-time updates without CPU intervention - critical for deterministic timing in field-oriented control (FOC) and sensorless BLDC commutation. The GPTWa timer unit (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) operate synchronously with PCLKC for precise waveform generation, while HRPWM overlays sub-nanosecond edge placement on GPTW0–GPTW3 outputs.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCDFP#10?

The R5F526TFCDFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless commutation without external co-processors. The RXv3 CPU core's single-cycle instruction execution and integrated FPU ensure deterministic timing critical for PWM synchronization and current regulation loops in the R5F526TFCDFP#10.

Does the R5F526TFCDFP#10 support IEC60730 Class C compliance?

Yes, the R5F526TFCDFP#10 includes multiple hardware features required for IEC60730 Class C certification, including oscillation-stoppage detection, A/D converter disconnection detection, clock accuracy measurement circuit, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, CRC calculator (CRCA), and register write protection. These capabilities are implemented in silicon and documented in the R01DS0407EJ0120 datasheet, enabling certified safety firmware development for the R5F526TFCDFP#10 without external safety monitors.

What package type and pin count does the R5F526TFCDFP#10 use?

The R5F526TFCDFP#10 uses a 100-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0100KB-B, measuring 14 mm × 14 mm with 0.5 mm pitch. This package provides 82 general-purpose I/O pins, two 5-V tolerant inputs, and dedicated signal routing for high-speed timers, analog peripherals, and CAN FD transceivers. The thermal pad and pin layout of the R5F526TFCDFP#10 support reliable operation in industrial environments up to +85°C ambient temperature.

How many A/D converter channels and sample-and-hold circuits does the R5F526TFCDFP#10 include?

The R5F526TFCDFP#10 integrates three 12-bit S12ADH A/D converter units: Unit 0 (4 channels with 3 sample-and-hold circuits), Unit 1 (4 channels with 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables simultaneous sampling across up to six analog inputs - essential for reconstructing motor phase currents and DC-link voltage in a single control cycle. The 0.9 µs minimum conversion time at 60 MHz ADCLK ensures high-bandwidth feedback for the R5F526TFCDFP#10's motor control applications.

What is the resolution and timing capability of the HRPWM in the R5F526TFCDFP#10?

The High-Resolution PWM (HRPWM) in the R5F526TFCDFP#10 achieves a minimum timing resolution of 260 ps when operating at 120 MHz, applied to GPTW0 through GPTW3 outputs. This allows precise edge placement for dead-time optimization, reducing shoot-through risk in 3-phase inverter bridges. The HRPWM operates as an overlay on the base GPTWa timer, enabling nanosecond-level adjustments without increasing CPU load - a key differentiator of the R5F526TFCDFP#10 in high-efficiency motor drive designs.
