Product details
Overview
R5F526TBDGFN#30 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#30 datasheet, R5F526TBDGFN#30 pinout, R5F526TBDGFN#30 application, or R5F526TBDGFN#30 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, with IEC60730-compliant safety features, on-chip FPU, and simultaneous sampling across three 12-bit A/D units.
Technical Context
The R5F526TBDGFN#30 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions (including DSP and floating-point), and collective register bank save for fast context switching in motor control interrupt routines. It integrates dual-bank flash for seamless firmware updates and Trusted Memory (TM) protection to prevent unauthorized code reading.
Its timing subsystem combines GPTWa (32-bit × 8 channels), MTU3d (16-bit × 9 channels), and HRPWM (4 channels) synchronized to PCLKC at up to 120 MHz, enabling precise dead-time insertion, phase-counting, and sub-nanosecond PWM edge placement - critical for high-efficiency inverter gate driving and current sensing synchronization.
