Product details
Overview
R5F526T9BGND#30 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 R5F526T9BGND#30 datasheet, R5F526T9BGND#30 pinout, R5F526T9BGND#30 application, or R5F526T9BGND#30 equivalent, key selection criteria include its dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, RAM test assist), and dedicated motor control peripherals including MTU3d, GPTWa, and HRPWM supporting real-time dead-time compensation and synchronous A/D triggering.
Technical Context
The R5F526T9BGND#30 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 loops. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, with independent PCLKA/PCLKC domains enabling 120 MHz peripheral operation (MTU/GPTW/HRPWM) while decoupling timing from system clock constraints.
Motor control execution relies on tightly coupled timer subsystems: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa delivers up to 10 single-phase or 3 three-phase complementary outputs; and HRPWM overlays 260 ps fine timing control on GPTW0–GPTW3 outputs. All are synchronized via ELC to eliminate CPU intervention during waveform updates or A/D trigger events.
