For engineers reviewing the R5F526TBCDND#30 datasheet, R5F526TBCDND#30 pinout, R5F526TBCDND#30 application, or R5F526TBCDND#30 equivalent, key selection criteria include its 100-pin PLQP0100KB-B package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, and dedicated HRPWM circuitry for precise gate timing in BLDC/PMSM drives.

Technical Context

The R5F526TBCDND#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and 113 instructions. Its memory subsystem includes dual-bank 512 KB flash enabling background programming while executing from alternate bank, and 64 KB zero-wait SRAM with SED error detection.

Timing architecture integrates PCLKA (up to 120 MHz) for GPTW/MTU/HRPWM, PCLKC (up to 120 MHz) as counter reference clock, and ADCLK (up to 60 MHz) for S12ADH - enabling synchronized high-speed PWM generation and sub-1 µs ADC conversion. The ELC enables interrupt-free inter-module triggering between MTU3d, GPTWa, and S12ADH for deterministic motor control loops.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F526TBCDND#30?

The R5F526TBCDND#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 single-precision FPU, and 113 instructions. Its architecture includes a collective register bank save function, memory protection unit (MPU), and JTAG/FINE debugging interfaces - all confirmed in the official R01DS0407EJ0120 datasheet.

Does the R5F526TBCDND#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBCDND#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps in FD mode and is implemented as a single-channel peripheral with dedicated TX/RX pins. This capability is explicitly documented in the "Communication function" section of the R01DS0407EJ0120 datasheet.

What ADC configuration does the R5F526TBCDND#30 provide, and how many channels support simultaneous sampling?

The R5F526TBCDND#30 includes three independent 12-bit S12ADH 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 up to 7 analog inputs - critical for three-phase current sensing in motor control. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK.

What is the purpose and resolution of the HRPWM feature in the R5F526TBCDND#30?

The High-Resolution PWM (HRPWM) in the R5F526TBCDND#30 extends the GPTWa timer to deliver 260 ps minimum timing resolution for rising/falling edge control of PWM waveforms. It operates on GPTW0–GPTW3 channels and is used to fine-tune dead times in inverter gate drivers - directly improving efficiency and reducing shoot-through risk in high-frequency motor drives.

Is the R5F526TBCDND#30 qualified for IEC60730 safety compliance, and which features support it?

Yes, the R5F526TBCDND#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, self-diagnostic A/D converter disconnection detection, clock frequency accuracy measurement, independent watchdog timer (IWDT), RAM test-assisting function (DOC), CRC calculator (CRCA), and register write protection. These are explicitly listed under "Useful functions for IEC60730 compliance" in the datasheet.
