Product details
Overview
R5F526TBDGFP#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 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 R5F526TBDGFP#10 datasheet, R5F526TBDGFP#10 pinout, R5F526TBDGFP#10 application, or R5F526TBDGFP#10 equivalent, key selection criteria include its dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC), and dedicated motor control peripherals including MTU3d, GPTWa, and HRPWM supporting real-time dead-time compensation and synchronous A/D triggering.
Technical Context
The R5F526TBDGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching-critical for deterministic motor control loop execution. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent 120 kHz IWDT oscillator, and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKC for timer reference).
Motor control capability is anchored by three synchronized timer subsystems: MTU3d (9-channel 16-bit) for 3-phase PWM with automatic dead-time insertion, GPTWa (8-channel 32-bit) supporting single-/3-/5-phase complementary modes, and HRPWM (4-channel) delivering 260 ps edge placement resolution at 120 MHz-enabling precise gate drive timing for SiC/GaN inverters.
