Product details
Overview
R5F526TBADFN#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 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 R5F526TBADFN#30 datasheet, R5F526TBADFN#30 pinout, R5F526TBADFN#30 application, or R5F526TBADFN#30 equivalent, key selection considerations include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated motor control peripherals including MTU3d, GPTWa, and POE3D for gate driver fault management.
Technical Context
The R5F526TBADFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching-enabling deterministic real-time motor control loops. Its clock system supports independent PCLKA (up to 120 MHz), PCLKC (up to 120 MHz for timer reference), and PCLKD (up to 60 MHz for ADC) domains, allowing precise timing separation between computation, PWM generation, and analog acquisition.
Motor-specific peripherals are tightly coupled: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and synchronous counter clearing; GPTWa delivers up to 10 single-phase or 3 three-phase complementary PWM outputs; and HRPWM achieves 260 ps edge placement resolution on GPTW0–GPTW3 outputs. The ELC enables interrupt-free inter-module triggering-e.g., MTU event directly initiating A/D conversion without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADFN#30 | Same RX26T family, identical 64-pin PWQN0064KF-A package, but with 256 KB flash and 48 KB SRAM | Lower memory capacity limits complex motion profiles or large lookup tables; suitable for cost-sensitive single-motor control | Select when firmware size <256 KB and RAM usage <48 KB suffices-reduces cost without sacrificing peripheral set or PWM capability |
| R5F523T5ADFP#30 | RX23T family, 100-pin LQFP, 256 KB flash, 64 KB SRAM, no HRPWM, lower max frequency (40 MHz) | Lacks 260 ps HRPWM and dual-bank flash; supports only basic 3-phase PWM-insufficient for SiC/GaN high-frequency inverters | Choose for legacy 40 MHz designs where HRPWM and CAN FD are not required; not drop-in compatible due to pin count and feature gap |
Compared with R5F526TBADFN#30, the R5F526TADFN#30 offers identical motor control peripherals and package but reduced memory-ideal for streamlined firmware. The R5F523T5ADFP#30 lacks HRPWM and dual-bank flash, limiting suitability for next-generation high-efficiency inverters requiring nanosecond-level PWM precision and safe firmware updates.
