Renesas R5F526TFCDND#50

Overview

R5F526TFCDND#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 R5F526TFCDND#50 datasheet, R5F526TFCDND#50 pinout, R5F526TFCDND#50 application, or R5F526TFCDND#50 equivalent, this MCU delivers deterministic real-time performance for closed-loop motor drives, supports IEC 60730 safety compliance via built-in self-test functions, and integrates high-resolution PWM (260 ps timing resolution) and simultaneous-sampling 12-bit ADCs for precise current/voltage sensing.

Technical Context

The R5F526TFCDND#50 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. Its clock system combines an 8–24 MHz external crystal with PLL to generate 120 MHz ICLK, while PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), PCLKC (up to 120 MHz), and PCLKD (up to 60 MHz) independently drive peripheral domains.

Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronized 3-phase PWM with automatic dead-time insertion; HRPWM provides 260 ps fine timing adjustment on GPTW0–GPTW3 outputs; S12ADH includes three 12-bit ADC units with simultaneous sampling across up to 22 channels for current reconstruction.
