Product details
Overview
R5F526TAAGFL#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and high-resolution PWM with 260 ps timing resolution. It targets inverter-driven industrial motors, servo drives, and digital power supplies.
For engineers reviewing the R5F526TAAGFL#50 datasheet, R5F526TAAGFL#50 pinout, R5F526TAAGFL#50 application, or R5F526TAAGFL#50 equivalent, key selection criteria include its 120 MHz real-time PWM capability, dual-bank flash for safe firmware updates, IEC60730-compliant safety features, and hardware-accelerated trigonometric functions (TFUv2) for field-oriented control (FOC) execution.
Technical Context
The R5F526TAAGFL#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-critical for deterministic motor control loops. Its clock system supports independent PCLKA (up to 120 MHz), PCLKC (up to 120 MHz for HRPWM/GPTW), and PCLKD (up to 60 MHz for ADC), enabling concurrent high-speed PWM generation and precise analog acquisition.
It integrates dedicated motor control peripherals: GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), HRPWM (4-channel, 260 ps resolution), POE3D/POEG for fault-safe output disable, and S12ADH with simultaneous sampling across three units-enabling synchronized current/voltage sensing in 3-phase inverters.
