Product details
Overview
R5F526TFBGFN#50 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, and hardware-accelerated 3-phase PWM generation with dead-time control. It supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TFBGFN#50 datasheet, R5F526TFBGFN#50 pinout, R5F526TFBGFN#50 application, or R5F526TFBGFN#50 equivalent, key selection criteria include its 100-pin LFQFP package, 120 MHz GPTWa/MTU3d timer subsystem for multi-phase motor drive timing, HRPWM with 260 ps resolution, dual-bank flash for safe firmware updates, and integrated analog peripherals (12-bit S12ADH ×3 units, CMPCa ×6, R12DAb ×2) enabling closed-loop current/voltage sensing without external signal conditioning.
Technical Context
The R5F526TFBGFN#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and collective register bank save for fast interrupt response. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent timing domains for ICLK (120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz).
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit ×8 channels) and MTU3d (16-bit ×9 channels) support simultaneous 3-phase complementary PWM with automatic dead-time insertion and phase-counting; ELC links A/D conversion triggers to timer events without CPU intervention; and POE3D/POEG provide hardware fault response for overcurrent or short-circuit detection on PWM outputs.
