Product details
Overview
R5F526TBCDFM#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 R5F526TBCDFM#10 datasheet, R5F526TBCDFM#10 pinout, R5F526TBCDFM#10 application, or R5F526TBCDFM#10 equivalent, key selection criteria include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated motor control peripherals including MTU3d (9-channel 16-bit timer), GPTWa (8-channel 32-bit PWM), and HRPWM (4-channel high-resolution PWM).
Technical Context
The R5F526TBCDFM#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-critical for real-time motor control loop execution. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, enabling independent domain clocking (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz) to optimize peripheral timing without CPU overhead.
Motor-specific timing is managed via tightly coupled peripherals: MTU3d supports 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa provides 10 single-phase, 3 three-phase, or 2 five-phase complementary PWM outputs; and HRPWM delivers 260 ps edge placement resolution synchronized to GPTW0–GPTW3 outputs-enabling precise gate drive timing for SiC/GaN inverters.
