Product details
Overview
R5F526T9AGFN#50 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 timing resolution.
For engineers reviewing the R5F526T9AGFN#50 datasheet, R5F526T9AGFN#50 pinout, R5F526T9AGFN#50 application, or R5F526T9AGFN#50 equivalent, this MCU delivers deterministic real-time motor control with IEC 60730-compliant safety features, on-chip FPU, dual-bank flash for seamless firmware updates, and high-resolution PWM synchronized to analog capture triggers - critical for servo drives, HVAC compressors, and industrial PMSM/BLDC inverters.
Technical Context
The R5F526T9AGFN#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching in interrupt-heavy motor control loops. Its clock system supports independent domain scaling: ICLK at 120 MHz for CPU/core logic, PCLKA at 120 MHz for MTU3d/GPTWa/HRPWM peripherals, and PCLKD at 60 MHz for S12ADH A/D conversion.
Motor control execution relies on tightly coupled timer subsystems: GPTWa (32-bit × 8 channels) provides flexible PWM waveform generation with dead-time insertion and synchronous start/stop; MTU3d (16-bit × 9 channels) enables 3-phase complementary output with automatic dead-time compensation; HRPWM (4 channels) overlays sub-nanosecond timing adjustments onto GPTW outputs for precise gate drive skew control.
