Product details
Overview
R5F526TFAGFM#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 interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526TFAGFM#10 datasheet, R5F526TFAGFM#10 pinout, R5F526TFAGFM#10 application, or R5F526TFAGFM#10 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, with IEC60730-compliant safety features, on-chip FPU, and dual-bank flash for safe firmware updates.
Technical Context
The R5F526TFAGFM#10 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision floating-point operations and 113 instructions including DSP extensions. Its memory protection unit (MPU) enforces eight configurable memory regions with 16-byte granularity for secure code partitioning.
Timing subsystems include three independent clock domains: ICLK (up to 120 MHz for CPU), PCLKA (up to 120 MHz for GPTW/MTU/HRPWM), and PCLKD (up to 60 MHz for S12ADH). The ELC enables direct inter-module event triggering without CPU intervention-critical for synchronized PWM, ADC sampling, and fault response in motor control loops.
