For engineers reviewing the R5F526TBDGFL#30 datasheet, R5F526TBDGFL#30 pinout, R5F526TBDGFL#30 application, or R5F526TBDGFL#30 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, IEC60730-compliant safety features (IWDT, oscillation-stop detection, RAM test assist), and dedicated motor control peripherals including MTU3d, GPTWa, and HRPWM.

Technical Context

The R5F526TBDGFL#30 implements the RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit multiplier, IEEE 754-compliant FPU, and MPU-enforced memory protection. It supports little-endian or big-endian data arrangement and includes register bank save for fast context switching in real-time motor control loops.

Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and selectable 16/18/20 MHz HOCO, PLL up to 120 MHz, and independent 120 kHz IWDT oscillator. Peripheral clocks are independently configurable: PCLKA at up to 120 MHz for MTU/GPTW/HRPWM/CAN FD, PCLKB at up to 60 MHz for most peripherals, and PCLKD at up to 60 MHz for the 12-bit A/D converter.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBDGFL#30?

The R5F526TBDGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit hardware multiplier, and zero-wait-state access to 512 KB on-chip flash and 64 KB SRAM-all confirmed in the R01DS0407EJ0120 Rev.1.20 datasheet. The R5F526TBDGFL#30 delivers deterministic real-time response essential for high-bandwidth motor control loops.

Does the R5F526TBDGFL#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBDGFL#30 integrates a CAN FD module compliant with ISO 11898-1:2015 for both standard and extended frames. It supports data rates up to 5 Mbps in FD mode and includes message filtering, FIFO buffering, and error handling logic. This capability is explicitly documented in Section 1.1 and Table 1.1 of the R01DS0407EJ0120 datasheet, making the R5F526TBDGFL#30 suitable for modern industrial networks requiring higher bandwidth than classical CAN.

What PWM resolution and channel count does the R5F526TBDGFL#30 provide for motor control?

The R5F526TBDGFL#30 provides three complementary PWM subsystems: 8-channel 32-bit GPTWa, 9-channel 16-bit MTU3d, and 4-channel HRPWM with a minimum resolution of 260 ps at 120 MHz. These are used together to generate non-overlapping 3-phase, 5-phase, or single-phase waveforms with hardware-dead-time insertion and fault-driven immediate disable via POEG inputs. All specifications are verified in Sections 1.1 and 1.4 of the R01DS0407EJ0120 datasheet.

How does the R5F526TBDGFL#30 support IEC60730 functional safety compliance?

The R5F526TBDGFL#30 includes multiple IEC60730-compliant features: independent watchdog timer (IWDT) with dedicated 120 kHz oscillator, main clock oscillation-stop detection, ADC self-diagnostic and disconnection detection, CRC calculator (CRCA), RAM test-assist function via DOC, and register write protection. These are detailed in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 datasheet and enable Class B certification without external safety components.

What package type and pin count does the R5F526TBDGFL#30 use?

The R5F526TBDGFL#30 uses a 100-pin LFQFP package designated PLQP0100KB-B: 14 mm × 14 mm body, 0.5 mm pitch, with exposed thermal pad. It provides 82 general-purpose I/O pins, two 5-V tolerant inputs, and dedicated pins for MTU/GPTW PWM outputs, CAN FD transceivers, and analog interfaces. This package information is confirmed in the "Package Information" section of the R01DS0407EJ0120 datasheet and Renesas ordering documentation for R5F526TBDGFL#30.
