Product details
Overview
R5F526TBBGFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, 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 targets inverter-driven industrial motors and servo systems requiring real-time precision, functional safety (IEC60730), and secure firmware execution.
For engineers reviewing the R5F526TBBGFL#10 datasheet, R5F526TBBGFL#10 pinout, R5F526TBBGFL#10 application, or R5F526TBBGFL#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 3-phase/5-phase complementary PWM capability, 12-bit ADC with simultaneous sampling across three units, and Trusted Secure IP Lite for AES-128/256 encryption and true random number generation.
Technical Context
The R5F526TBBGFL#10 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 for 120 MHz system clock, and dedicated 120 kHz IWDT oscillator - all supporting IEC60730 oscillation-stop detection.
Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts/stops, ADC conversions, or port output changes without CPU intervention - critical for deterministic motor control loops. The GPTWa timer supports synchronous multi-channel PWM with dead-time compensation, while HRPWM refines edge placement down to 260 ps at 120 MHz.
