Product details
Overview
R5F526TBBGNE#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 complementary PWM with dead-time control. It supports IEC60730 safety compliance and operates across –40°C to +105°C.
For engineers reviewing the R5F526TBBGNE#10 datasheet, R5F526TBBGNE#10 pinout, R5F526TBBGNE#10 application, or R5F526TBBGNE#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 83 general-purpose I/O pins with 5-V tolerance - all critical for real-time motor drive firmware and functional safety certification.
Technical Context
The R5F526TBBGNE#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching. Its clock system integrates an 8–24 MHz external crystal oscillator, PLL, and dedicated 120 kHz IWDT oscillator - enabling precise timing for motor control loops and independent watchdog supervision.
Peripheral coordination is managed via the Event Link Controller (ELC), which interconnects 183 internal event signals - allowing MTU3d timers, GPTWa PWM units, and S12ADH ADCs to operate synchronously without CPU intervention during sleep mode. This architecture supports deterministic, low-latency response to current-sensing triggers and fault conditions in inverter gate drivers.
