Product details
Overview
R5F526TFDDFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM with dead-time control - deployed in HVAC compressors, servo drives, and BLDC motor controllers.
For engineers reviewing the R5F526TFDDFL#10 datasheet, R5F526TFDDFL#10 pinout, R5F526TFDDFL#10 application, or R5F526TFDDFL#10 equivalent, key selection criteria include verified 120 MHz PWM timing resolution (260 ps minimum), dual-bank flash for safe firmware updates, IEC60730-compliant self-test features, and pin-confirmed support for 100-pin LFQFP package with 82 general-purpose I/Os including 5-V tolerant inputs and large-current outputs.
Technical Context
The R5F526TFDDFL#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 real-time field-oriented control (FOC) algorithms. Its clock system integrates PLL with external 8–24 MHz crystal input, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator.
Peripheral coordination is managed via Event Link Controller (ELC), supporting 183 internal event signals to trigger timer starts, A/D conversions, or PWM updates without CPU intervention - critical for deterministic motor phase timing. The GPTWa timer unit operates at PCLKC up to 120 MHz and synchronizes with MTU3d and HRPWM for sub-nanosecond waveform alignment in inverter gate drive.
