Product details
Overview
R5F526TFCGFP#10 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/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526TFCGFP#10 datasheet, R5F526TFCGFP#10 pinout, R5F526TFCGFP#10 application, or R5F526TFCGFP#10 equivalent, this MCU delivers deterministic real-time motor control with IEC60730-compliant safety features, on-chip FPU, dual-bank flash for safe firmware updates, and simultaneous sampling across three 12-bit A/D units - critical for field-oriented control (FOC) and sensorless BLDC commutation.
Technical Context
The R5F526TFCGFP#10 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting 113 instructions including DSP and floating-point operations compliant with IEEE 754. Its memory protection unit (MPU) enforces eight configurable memory regions with per-region read/write/execute permissions, while Trusted Memory (TM) restricts code fetch access to protected flash areas.
Real-time motor control is enabled by tightly coupled peripherals: GPTWa timers synchronized to PCLKC at up to 120 MHz drive high-resolution PWM outputs; HRPWM circuitry achieves 260 ps edge placement resolution; and ELC links MTU3d, GPTWa, and S12ADH triggers without CPU intervention - enabling precise, low-latency current/voltage sampling and gate drive timing.
