Product details
Overview
R5F526TBDGFN#50 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 timing resolution.
For engineers reviewing the R5F526TBDGFN#50 datasheet, R5F526TBDGFN#50 pinout, R5F526TBDGFN#50 application, or R5F526TBDGFN#50 equivalent, this MCU delivers deterministic real-time motor control with IEC60730-compliant safety features, high-resolution HRPWM, 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 R5F526TBDGFN#50 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions, 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 120 MHz peripheral operation (GPTW, MTU3d, HRPWM) and 60 MHz A/D conversion timing.
Motor control functionality is anchored by the GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel sub-260 ps edge placement), all tightly coupled via ELC for event-triggered, CPU-free waveform synchronization, dead-time insertion, and A/D trigger generation - eliminating software latency in closed-loop current/voltage regulation.
