Product details
Overview
R5F526TBAGNE#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 complementary PWM generation with dead-time control.
For engineers reviewing the R5F526TBAGNE#30 datasheet, R5F526TBAGNE#30 pinout, R5F526TBAGNE#30 application, or R5F526TBAGNE#30 equivalent, key selection considerations include its 100-pin LQFP package, 120 MHz real-time PWM timing resolution (260 ps HRPWM), IEC60730 safety support, dual-bank flash for safe firmware updates, and dedicated motor control peripherals including MTU3d and GPTWa timers.
Technical Context
The R5F526TBAGNE#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast interrupt response. It integrates a memory protection unit (MPU) and Trusted Memory (TM) for secure code execution in safety-critical systems.
Its motor control architecture combines three timer subsystems: MTU3d (9-channel 16-bit) for 3-phase inverter gate drive, GPTWa (8-channel 32-bit) for high-resolution PWM waveform synthesis, and HRPWM (4-channel) delivering 260 ps timing resolution synchronized to GPTW outputs - all coordinated via the Event Link Controller (ELC) without CPU intervention.
