For engineers reviewing the R5F526T9BDND#30 datasheet, R5F526T9BDND#30 pinout, R5F526T9BDND#30 application, or R5F526T9BDND#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM resolution, IEC60730 safety support, and 100-pin PLQP0100KB-B package with 82 general-purpose I/O pins including 5-V tolerant inputs.

Technical Context

The R5F526T9BDND#30 implements the RXv3 CPU core with single-precision FPU, 113 instructions, and collective register bank save for fast context switching in real-time motor control loops. It integrates dual-bank flash for safe firmware updates and supports simultaneous sampling across three 12-bit A/D units (S12ADH) with programmable gain amplifiers.

Its timing subsystem combines MTU3d (16-bit × 9 channels), GPTWa (32-bit × 8 channels), and HRPWM (4 channels) synchronized to PCLKC at up to 120 MHz, enabling precise phase-aligned PWM generation for 3-phase inverters. The ELC enables event-triggered peripheral coordination without CPU intervention - critical for deterministic control execution.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9BDND#30?

The R5F526T9BDND#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance level is enabled by the RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and 32-bit multiplier/divider - making it suitable for computationally intensive motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) in real time.

Does the R5F526T9BDND#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9BDND#30 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assist using the Data Operation Controller (DOC), CRC calculator (CRCA), memory protection unit (MPU), register write protection, and self-diagnostic A/D functions. These are documented in the R01DS0407EJ0120 datasheet and enable streamlined safety validation for industrial motor drive applications.

What PWM capabilities does the R5F526T9BDND#30 offer for 3-phase inverter control?

The R5F526T9BDND#30 provides comprehensive PWM support for 3-phase inverters: MTU3d delivers 3-channel 3-phase complementary PWM with automatic dead-time insertion, GPTWa supplies 10-channel single-phase complementary PWM, and HRPWM adds 4 channels with 260 ps minimum resolution for fine-tuning edge timing. All are synchronized to PCLKC at up to 120 MHz and controllable via ELC for jitter-free operation.

How many analog-to-digital converter channels does the R5F526T9BDND#30 support, and what is their architecture?

The R5F526T9BDND#30 integrates three 12-bit A/D units (S12ADH): 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 architecture enables true simultaneous sampling across up to 7 channels - critical for accurate current reconstruction in 3-phase motor control - with programmable sampling time per channel and digital comparison functionality.

What package type and pin count does the R5F526T9BDND#30 use, and what I/O features does it provide?

The R5F526T9BDND#30 uses the PLQP0100KB-B package: a 100-pin LQFP with 14 mm × 14 mm body and 0.5 mm pitch. It provides 82 general-purpose I/O pins, including 2 pins with 5-V tolerance, 82 pull-up resistors, 82 open-drain outputs, and 15 large-current output pins - supporting direct interface to gate drivers, optocouplers, and industrial sensors without external level-shifting components.
