Product details
Overview
R5F526T8AGFM#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, CAN FD interface, and integrated high-resolution PWM (260 ps minimum resolution) for precise 3-phase/5-phase inverter gate timing.
For engineers reviewing the R5F526T8AGFM#10 datasheet, R5F526T8AGFM#10 pinout, R5F526T8AGFM#10 application, or R5F526T8AGFM#10 equivalent, this MCU delivers deterministic real-time control with IEC60730-compliant safety features, dual-bank flash for safe firmware updates, hardware-accelerated trigonometric functions (TFUv2), and simultaneous sampling across three 12-bit A/D units - critical for sensorless FOC motor control.
Technical Context
The R5F526T8AGFM#10 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU - enabling efficient field-oriented control (FOC) math. Its clock system supports 8–24 MHz external crystal input to PLL, generating up to 120 MHz ICLK while maintaining independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains for peripheral timing isolation.
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide complementary PWM with automatic dead-time insertion and synchronous counter clearing; HRPWM adds 260 ps timing adjustment to GPTW0–GPTW3 outputs; S12ADH supports simultaneous sampling across three units (4+4+14 channels) with programmable gain amplifiers on two units - all coordinated via ELC without CPU intervention.
