Product details
Overview
R5F526TFBGFP#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and 3-phase/5-phase complementary PWM generation with hardware dead-time control.
For engineers reviewing the R5F526TFBGFP#10 datasheet, R5F526TFBGFP#10 pinout, R5F526TFBGFP#10 application, or R5F526TFBGFP#10 equivalent, this MCU delivers deterministic real-time motor timing via GPTWa and MTU3d timers, high-resolution HRPWM (260 ps min. resolution), IEC60730-compliant safety features, and on-chip Trusted Secure IP Lite encryption - critical for certified industrial drive designs.
Technical Context
The R5F526TFBGFP#10 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and 113 instructions including DSP extensions. Its memory subsystem includes dual-bank 512 KB flash enabling background programming and bank-swapping during runtime.
Timing architecture integrates three independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz, PCLKC up to 120 MHz) to decouple high-speed PWM/ADC operations from lower-speed peripherals. The ELC enables event-triggered module coordination without CPU intervention - essential for synchronized PWM, ADC sampling, and fault response in motor control loops.
