For engineers reviewing the R5F526TBDDNE#30 datasheet, R5F526TBDDNE#30 pinout, R5F526TBDDNE#30 application, or R5F526TBDDNE#30 equivalent, this MCU supports high-resolution PWM generation (260 ps timing resolution), simultaneous sampling across three 12-bit A/D converter units, hardware-accelerated trigonometric functions (TFUv2), and IEC 60730 safety features including oscillation-stop detection, RAM test assistance, and register write protection.

Technical Context

The R5F526TBDDNE#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and support for little-endian or big-endian data arrangement. It integrates a dedicated 120 MHz system clock (ICLK), PCLKA/PCLKB/PCLKC/PCLKD peripheral clocks up to 120 MHz/60 MHz/120 MHz/60 MHz respectively, and independent IWDT-dedicated 120 kHz oscillator.

Its motor control architecture combines GPTWa (32-bit × 8 channels), MTU3d (16-bit × 9 channels), HRPWM (4 channels with 260 ps resolution), and POE3D/POEG output enable logic to generate non-overlapping complementary PWM waveforms with programmable dead time, synchronized A/D conversion triggers, and short-circuit fault response without CPU intervention via ELC.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBDDNE#30?

The R5F526TBDDNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 16 general-purpose 32-bit registers, and optimized pipeline design-enabling deterministic real-time response in motor control loops.

Does the R5F526TBDDNE#30 support IEC 60730 functional safety requirements?

Yes, the R5F526TBDDNE#30 includes hardware features supporting Class B compliance per IEC 60730, such as main clock oscillation stop detection, ADC disconnection monitoring, clock frequency accuracy measurement, independent watchdog timer (IWDTa), RAM test assistance via DOC, and register write protection-reducing software certification effort for household and industrial appliances.

What PWM resolution does the R5F526TBDDNE#30 achieve with its HRPWM feature?

The R5F526TBDDNE#30 achieves a minimum PWM timing resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit, which fine-tunes the rising/falling edges of waveforms generated by GPTWa channels. This resolution is realized at 120 MHz operation and enables precise dead-time control and reduced torque ripple in 3-phase inverter applications.

How many A/D converter channels does the R5F526TBDDNE#30 support, and what is their architecture?

The R5F526TBDDNE#30 supports 22 total 12-bit A/D channels distributed across three S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit includes dedicated sample-and-hold circuits, and all support simultaneous sampling triggered by MTU/GPTW events-critical for accurate current/voltage acquisition in motor control.

What package type and thermal specifications apply to the R5F526TBDDNE#30?

The R5F526TBDDNE#30 uses the PLQP0100KB-B package: a 100-pin LQFP with 14 mm × 14 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for the D-version operating temperature range of –40°C to +85°C, making it suitable for industrial environments where reliability under thermal stress is essential.
