Product details
Overview
R5F526TFBDFL#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, 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 +85°C.
For engineers reviewing the R5F526TFBDFL#50 datasheet, R5F526TFBDFL#50 pinout, R5F526TFBDFL#50 application, or R5F526TFBDFL#50 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit A/D units, 3-phase complementary PWM generation with automatic dead-time insertion, and Trusted Secure IP Lite encryption support.
Technical Context
The R5F526TFBDFL#50 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. Its clock system integrates an 8–24 MHz external crystal oscillator, PLL, and dedicated 120 kHz IWDT oscillator - all supporting independent domain clocking (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts/stops, A/D conversions, or port output changes without CPU intervention. The GPTWa timer unit (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) operate synchronously with PCLKC for precise PWM and phase-counting in motor drive applications.
