Product details
Overview
R5F526TFDDFN#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 complementary PWM generation with dead-time control.
For engineers reviewing the R5F526TFDDFN#30 datasheet, R5F526TFDDFN#30 pinout, R5F526TFDDFN#30 application, or R5F526TFDDFN#30 equivalent, this device supports IEC60730-compliant safety functions, high-resolution PWM (260 ps timing resolution), simultaneous sampling across three 12-bit A/D units, and Trusted Secure IP Lite encryption - all in a compact 64-pin HWQFN package.
Technical Context
The R5F526TFDDFN#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. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator.
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronous 3-phase PWM output with automatic dead-time insertion, while ELC links timer events to A/D triggers without CPU intervention - critical for real-time current sensing and field-oriented control loops.
