It supports IEC60730 safety compliance and operates across –40°C to +85°C.

For engineers reviewing the R5F526TFCDND#30 datasheet, R5F526TFCDND#30 pinout, R5F526TFCDND#30 application, or R5F526TFCDND#30 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, 3-phase/5-phase complementary PWM capability, and Trusted Secure IP Lite encryption engine supporting AES-128/256.

Technical Context

The R5F526TFCDND#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at lower rates).

Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronous PWM generation, dead-time insertion, and phase-counting; HRPWM provides 260 ps resolution on GPTW0–GPTW3 outputs; S12ADH includes three 12-bit A/D units with simultaneous sampling across 22 channels (Unit 0: 4 ch × 3 SH, Unit 1: 4 ch × 3 SH, Unit 2: 14 ch).

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCDND#30?

The R5F526TFCDND#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables real-time execution of Field-Oriented Control (FOC) algorithms with minimal interrupt latency. The RXv3 CPU core delivers single-cycle instruction execution and includes a single-precision floating-point unit compliant with IEEE 754 - making the R5F526TFCDND#30 well-suited for computationally intensive motor control tasks.

Does the R5F526TFCDND#30 support IEC60730 Class B functional safety certification?

Yes, the R5F526TFCDND#30 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection for main clock, self-diagnostic A/D converter functions, RAM test assist using DOC, CRC calculator (CRCA), register write protection, and independent watchdog timer with window function. These capabilities reduce the need for external safety components and simplify certification efforts for motor control applications.

What package type and pin count does the R5F526TFCDND#30 use?

The R5F526TFCDND#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package measuring 14 × 14 mm with 0.5 mm pitch. This LFQFP package supports standard reflow soldering processes and provides full access to all 82 general-purpose I/O pins, including 5-V tolerant inputs and open-drain outputs - ideal for industrial drive board layouts requiring robust signal routing and thermal management.

How many A/D converter channels and sample-and-hold units does the R5F526TFCDND#30 support?

The R5F526TFCDND#30 supports 22 total 12-bit A/D converter channels distributed across three independent 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 true simultaneous sampling across all three units - a critical capability for capturing phase currents and DC-link voltage concurrently in FOC implementations.

What is the resolution and application of the High-Resolution PWM (HRPWM) in the R5F526TFCDND#30?

The R5F526TFCDND#30 features a High-Resolution PWM (HRPWM) module delivering 260 ps minimum timing resolution on GPTW0–GPTW3 outputs. This precision enables sub-nanosecond edge placement for minimizing dead-time distortion and reducing torque ripple in high-performance motor drives. HRPWM operates in conjunction with the 32-bit GPTWa timers and is especially valuable in servo and spindle applications where waveform fidelity directly impacts mechanical smoothness and efficiency.
