Overview

R5F526TFDGFN#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.

For engineers reviewing the R5F526TFDGFN#30 datasheet, R5F526TFDGFN#30 pinout, R5F526TFDGFN#30 application, or R5F526TFDGFN#30 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (IWDT, oscillation-stop detection, RAM test assist), and dedicated motor control peripherals including MTU3d, GPTWa, and HRPWM.

Technical Context

The R5F526TFDGFN#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting 113 instructions including DSP and single-precision floating-point operations compliant with IEEE 754. It integrates a memory protection unit (MPU) and Trusted Memory (TM) for secure code execution in safety-critical systems.

Its motor control subsystem combines three timer families-MTU3d (16-bit, 9 channels), GPTWa (32-bit, 8 channels), and HRPWM (4 channels)-with synchronized event linking via ELC to enable real-time, interrupt-free waveform generation, dead-time compensation, and A/D conversion triggering without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDGFN#30?

The R5F526TFDGFN#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution and efficient pipeline design, allowing the R5F526TFDGFN#30 to execute complex motor control algorithms-including field-oriented control (FOC) and space vector modulation-in real time without latency bottlenecks.

Does the R5F526TFDGFN#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFDGFN#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps in FD mode. This capability enables high-bandwidth diagnostics, firmware updates, and real-time motor status reporting in modern industrial and automotive networks - a feature not present in earlier RX23T or RX66T derivatives.

What PWM resolution does the R5F526TFDGFN#30 provide, and how is it implemented?

The R5F526TFDGFN#30 delivers a minimum PWM timing resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit applied to GPTW0–GPTW3 outputs. This is achieved by leveraging the 120 MHz system clock and dedicated fine-tuning logic that adjusts rising/falling edges independently - enabling precise dead-time control essential for minimizing shoot-through losses in SiC/GaN-based inverters.

How does the R5F526TFDGFN#30 support IEC60730 functional safety compliance?

The R5F526TFDGFN#30 includes multiple hardware features for IEC60730 Class B compliance: an independent watchdog timer (IWDT) with dedicated 120 kHz oscillator, main clock oscillation stop detection, CRC calculator (CRCA), register write protection, self-diagnostic A/D disconnection detection, and RAM test-assist functions. These capabilities are documented in Renesas' official safety manual R01UL0122EJ0200 and reduce external component dependencies for certification.

What package type and pin count does the R5F526TFDGFN#30 use?

The R5F526TFDGFN#30 uses a 100-pin Low-Profile Quad Flat Package (LFQFP) with PLQP0100KB-B footprint: 14 × 14 mm body, 0.5 mm pitch, and exposed thermal pad. This package provides 82 general-purpose I/O pins with 5-V tolerance, 15 high-current outputs, and dedicated analog/digital power domains - optimized for thermal management and noise immunity in high-density motor control PCB layouts.
