Product details
Overview
R5F526TFAGFM#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 interface, and hardware-accelerated 3-phase complementary PWM with dead-time control. It supports IEC60730 safety compliance and operates across –40°C to +105°C.
For engineers reviewing the R5F526TFAGFM#50 datasheet, R5F526TFAGFM#50 pinout, R5F526TFAGFM#50 application, or R5F526TFAGFM#50 equivalent, key selection criteria include its 120 MHz GPTWa timer with 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 83-pin PLQP0100KB-B package with 5-V tolerant I/Os for robust industrial interfacing.
Technical Context
The R5F526TFAGFM#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and MPU-based memory protection. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator - enabling precise timing isolation for safety-critical functions.
Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) support simultaneous 3-phase/5-phase PWM generation, while ELC links A/D conversion triggers directly to timer events without CPU intervention - reducing jitter and latency in closed-loop systems.
