Product details
Overview
R5F526TBDGFM#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 HRPWM timing resolution.
For engineers reviewing the R5F526TBDGFM#30 datasheet, R5F526TBDGFM#30 pinout, R5F526TBDGFM#30 application, or R5F526TBDGFM#30 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, with IEC 60730-compliant safety features, on-chip FPU, and dual-bank flash for safe firmware updates.
Technical Context
The R5F526TBDGFM#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting 113 instructions including DSP and floating-point operations, and integrates a memory protection unit (MPU) and Trusted Memory (TM) for secure code execution. Its clock system combines an 8–24 MHz external crystal with PLL synthesis and independent 120 kHz IWDT oscillator.
Real-time motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), HRPWM (4-channel high-resolution PWM), S12ADH (three 12-bit ADC units with simultaneous sampling), and CMPCa (6-channel analog comparator), all synchronized via PCLKA/PCLKC up to 120 MHz and coordinated through the Event Link Controller (ELC).
