Product details
Overview
R5F526T9AGFP#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, 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 supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526T9AGFP#10 datasheet, R5F526T9AGFP#10 pinout, R5F526T9AGFP#10 application, or R5F526T9AGFP#10 equivalent, this MCU delivers deterministic real-time control for 3-phase and 5-phase motor drives, embedded power conversion, and safety-critical industrial systems requiring simultaneous analog sampling, secure firmware execution, and robust communication.
Technical Context
The R5F526T9AGFP#10 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. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator - all supporting precise timing for motor control loops.
Peripheral architecture centers on event-driven operation via the Event Link Controller (ELC), enabling hardware-triggered GPTW/MTU timer starts, A/D conversion triggers, and comparator-linked PWM dead-time compensation - all without CPU intervention during sleep or active modes.
