Product details
Overview
R5F526TFAGFP#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 complementary PWM generation with dead-time control.
For engineers reviewing the R5F526TFAGFP#50 datasheet, R5F526TFAGFP#50 pinout, R5F526TFAGFP#50 application, or R5F526TFAGFP#50 equivalent, this MCU delivers deterministic real-time performance for closed-loop motor drives, supports IEC 60730 safety compliance via self-test functions and MPU, and integrates high-resolution PWM (260 ps timing resolution) for precise gate driving in BLDC/PMSM inverters.
Technical Context
The R5F526TFAGFP#50 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and collective register bank save for fast interrupt response. Its memory subsystem includes dual-bank flash enabling background programming while executing from alternate bank, and 64 KB of no-wait SRAM with SED error detection.
Real-time peripheral coordination is achieved via the Event Link Controller (ELC), which enables direct inter-module triggering without CPU intervention - critical for synchronized A/D conversion start, PWM edge modulation, and fault response across MTU3d, GPTWa, and HRPWM modules operating on independent PCLKA/PCLKC domains.
