Product details
Overview
R5F526TFCDFP#30 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/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526TFCDFP#30 datasheet, R5F526TFCDFP#30 pinout, R5F526TFCDFP#30 application, or R5F526TFCDFP#30 equivalent, key selection criteria include its dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated high-resolution PWM for precise gate drive timing in BLDC/PMSM inverters.
Technical Context
The R5F526TFCDFP#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU. Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and 16/18/20 MHz HOCO, and PLL supporting 120 MHz system clock with independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at lower ratios).
Motor control capability is anchored by three timer subsystems: MTU3d (16-bit × 9 channels) for 3-phase complementary PWM with automatic dead-time insertion; GPTWa (32-bit × 8 channels) supporting single-/3-/5-phase modes and synchronous start/stop; and HRPWM (4 channels) providing 260 ps minimum resolution for fine-grained edge positioning of GPTW-generated waveforms.
