Product details
Overview
R5F526TFCDFM#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/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526TFCDFM#10 datasheet, R5F526TFCDFM#10 pinout, R5F526TFCDFM#10 application, or R5F526TFCDFM#10 equivalent, this MCU delivers deterministic real-time motor control with IEC 60730-compliant safety features, on-chip FPU, dual-bank flash for seamless firmware updates, and simultaneous sampling across three 12-bit A/D units - critical for high-fidelity current/voltage sensing in PMSM and BLDC drives.
Technical Context
The R5F526TFCDFM#10 integrates the RXv3 CPU core with single-precision FPU and memory protection unit (MPU), operating at 120 MHz with 709 CoreMark performance. Its clock system combines an 8–24 MHz external crystal with PLL synthesis and dedicated 120 kHz IWDT oscillator for fail-safe timing.
Motor control execution relies on tightly coupled peripherals: GPTWa (32-bit, 8-channel) and MTU3d (16-bit, 9-channel) timers deliver synchronized PWM outputs, while HRPWM provides sub-nanosecond edge placement. The S12ADH ADC supports simultaneous sampling across three units (4+4+14 channels) with programmable gain amplifiers and analog input disconnection detection - all essential for field-oriented control (FOC) loop integrity.
