Product details
Overview
R5F526TFADFM#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 code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and 3-phase/5-phase complementary PWM generation with hardware dead-time control.
For engineers reviewing the R5F526TFADFM#10 datasheet, R5F526TFADFM#10 pinout, R5F526TFADFM#10 application, or R5F526TFADFM#10 equivalent, this MCU delivers deterministic real-time motor timing via GPTWa and MTU3d timers, high-resolution PWM (260 ps min. resolution), IEC60730-compliant safety features, and Trusted Secure IP Lite encryption - all in a 100-pin LFQFP package rated for –40°C to +85°C operation.
Technical Context
The R5F526TFADFM#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 supports 8–24 MHz external crystal input with PLL multiplication to 120 MHz, plus independent 120-kHz IWDT oscillator and selectable internal HOCO/LOCO sources.
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) operate synchronously with PCLKC up to 120 MHz, while HRPWM provides sub-nanosecond edge placement on four GPTW channels. The ELC links timer events directly to A/D triggers and port outputs without CPU intervention.
