Product details
Overview
R5F526TFAGND#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 PWM generation with dead-time control.
For engineers reviewing the R5F526TFAGND#50 datasheet, R5F526TFAGND#50 pinout, R5F526TFAGND#50 application, or R5F526TFAGND#50 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, IEC60730-compliant safety features, and PLQP0100KB-B 100-pin QFP package supporting 82 general-purpose I/Os with 5-V tolerance.
Technical Context
The R5F526TFAGND#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-enabling deterministic real-time motor control loops. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator for fail-safe timing.
Peripheral integration centers on high-precision timing: MTU3d (9-channel 16-bit) and GPTWa (8-channel 32-bit) timers support synchronous 3-phase PWM output with automatic dead-time insertion, while HRPWM extends edge placement resolution to 260 ps at 120 MHz-critical for minimizing torque ripple in PMSM/BLDC drives.
