Product details
Overview
R5F526T9BGFN#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 high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and operates across –40°C to +105°C.
For engineers reviewing the R5F526T9BGFN#30 datasheet, R5F526T9BGFN#30 pinout, R5F526T9BGFN#30 application, or R5F526T9BGFN#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.
Technical Context
The R5F526T9BGFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching in interrupt-heavy motor control loops. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling precise timing isolation between control, communication, and safety domains.
Peripheral coordination is handled by the Event Link Controller (ELC), which interconnects 183 internal event signals - allowing MTU3d timers, GPTWa PWM units, and S12ADH ADCs to trigger each other without CPU intervention. This enables synchronous sampling, dead-time compensated PWM generation, and real-time fault response in brushless DC and PMSM motor drives.
