Overview
R5F526TFDGFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, integrated 512 KB code flash, 64 KB SRAM, 16 KB data flash, CAN FD interface, and high-resolution PWM (260 ps timing resolution) for precise 3-phase/5-phase inverter gate driving.
For engineers reviewing the R5F526TFDGFL#10 datasheet, R5F526TFDGFL#10 pinout, R5F526TFDGFL#10 application, or R5F526TFDGFL#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, IEC60730-compliant safety features (IWDT, oscillation-stop detection, RAM test assist), and dedicated HRPWM channels synchronized with GPTWa timers.
Technical Context
The R5F526TFDGFL#10 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU. It supports little-endian or big-endian data arrangement and includes a collective register bank save function for fast context switching in real-time motor control loops.
Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and 16/18/20 MHz HOCO, and PLL for 120 MHz system clock generation. Peripheral clocks are independently configurable: PCLKA (up to 120 MHz) for MTU3d/GPTWa/HRPWM/CAN FD, PCLKB (up to 60 MHz) for SCI/RSCI/RIIC, and PCLKD (up to 60 MHz) for S12ADH A/D conversion.
