Product details
Overview
R5F526TFCGFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 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 R5F526TFCGFL#10 datasheet, R5F526TFCGFL#10 pinout, R5F526TFCGFL#10 application, or R5F526TFCGFL#10 equivalent, this MCU is evaluated for real-time motor phase timing, embedded safety compliance (IEC60730), high-resolution PWM waveform alignment, and deterministic interrupt latency in closed-loop servo drives.
Technical Context
The R5F526TFCGFL#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 in motor control ISRs. It integrates dual-bank flash for safe firmware updates and Trusted Memory (TM) to protect critical startup code from read-out.
Its peripheral architecture centers on deterministic timing: GPTWa timers run at 120 MHz with PCLKC-synchronized counter clocks, HRPWM achieves 260 ps resolution for sub-nanosecond edge placement, and ELC enables CPU-free inter-module event chaining-e.g., MTU3d A/D trigger → S12ADH conversion → CRCA checksum → DTCb transfer-without interrupt overhead.
