Product details
Overview
R5F526TFCDFL#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 PWM generation with dead-time control.
For engineers reviewing the R5F526TFCDFL#10 datasheet, R5F526TFCDFL#10 pinout, R5F526TFCDFL#10 application, or R5F526TFCDFL#10 equivalent, key selection criteria include its 120 MHz real-time PWM timing resolution (260 ps minimum), dual-bank flash for safe firmware updates, IEC60730-compliant safety features including oscillation-stop detection and RAM test assistance, and support for simultaneous sampling across three 12-bit A/D units.
Technical Context
The R5F526TFCDFL#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching-critical for deterministic motor control loops. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator to ensure timing integrity during voltage transients.
Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals-including MTU3d/GPTWa timer triggers and A/D conversion starts-to interlink without CPU intervention. This architecture supports synchronized PWM waveform generation, analog sampling, and fault response in sub-microsecond latency, essential for field-oriented control (FOC) in brushless DC and PMSM drives.
