Renesas R5F526TBCDFM#50

Overview

R5F526TBCDFM#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring 120 MHz operation, 512 KB on-chip flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and high-resolution PWM with 260 ps timing resolution. It targets inverter-driven industrial motors and servo systems requiring IEC60730 safety compliance and real-time analog signal processing.

For engineers reviewing the R5F526TBCDFM#50 datasheet, R5F526TBCDFM#50 pinout, R5F526TBCDFM#50 application, or R5F526TBCDFM#50 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit ADC units, 3-phase/5-phase complementary PWM generation, and Trusted Secure IP Lite encryption support.

Technical Context

The R5F526TBCDFM#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and collective register bank save for fast context switching. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz, PCLKC/PCLKD up to 120/60 MHz).

Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronized PWM output with dead-time insertion and phase-counting; HRPWM achieves 260 ps resolution on GPTW0–GPTW3 outputs; S12ADH provides three independent 12-bit ADC units with sample-and-hold for simultaneous current/voltage sensing.
