Product details
Overview
R5F526TFCDND#10 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 R5F526TFCDND#10 datasheet, R5F526TFCDND#10 pinout, R5F526TFCDND#10 application, or R5F526TFCDND#10 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across three 12-bit A/D units, 260 ps high-resolution PWM timing, IEC60730 safety support, and Trusted Secure IP Lite encryption - critical for BLDC/PMSM drive firmware validation and functional safety certification.
Technical Context
The R5F526TFCDND#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 during interrupt-driven motor commutation. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent 120 kHz IWDT oscillator, and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at 60–120 MHz) enabling precise timing separation between control loops and communication stacks.
Motor-specific peripherals include eight 32-bit GPTWa channels supporting single-/3-/5-phase complementary PWM with automatic dead-time insertion, nine-channel MTU3d for position capture and encoder interfacing, six-channel analog comparator with programmable reference selection, and dual 12-bit D/A outputs usable as comparator references - all coordinated via Event Link Controller (ELC) to eliminate CPU intervention during waveform generation and ADC triggering.
