Product details
Overview
R5F526TBDGNE#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 HRPWM timing resolution.
For engineers reviewing the R5F526TBDGNE#10 datasheet, R5F526TBDGNE#10 pinout, R5F526TBDGNE#10 application, or R5F526TBDGNE#10 equivalent, this MCU delivers deterministic real-time motor control with IEC60730-compliant safety features, dual-bank flash for seamless 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 R5F526TBDGNE#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 in interrupt-heavy motor control loops. Its clock system supports PLL-synthesized 120 MHz ICLK with independent PCLKA/PCLKC domains enabling concurrent high-speed peripheral operation - including GPTWa timers running at 120 MHz and HRPWM reference clocks synchronized to PCLKC.
It integrates dedicated motor control peripherals: MTU3d for 3-phase complementary PWM with automatic dead-time insertion, GPTWa for flexible waveform generation (up to 10 single-phase or 3 three-phase outputs), and HRPWM for sub-nanosecond edge placement. The S12ADH ADC supports simultaneous sampling across three units (4+4+14 channels), directly feeding current/voltage feedback into FOC algorithms without software coordination.
