Product details
Overview
R5F526TFCGFP#50 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 R5F526TFCGFP#50 datasheet, R5F526TFCGFP#50 pinout, R5F526TFCGFP#50 application, or R5F526TFCGFP#50 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, with IEC60730-compliant safety features, high-resolution PWM (260 ps min. timing resolution), and dual-bank flash for safe firmware updates.
Technical Context
The R5F526TFCGFP#50 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-enabling responsive motor control loop execution at 120 MHz. It integrates dedicated peripherals including GPTWa (8-channel 32-bit general PWM timer), MTU3d (9-channel 16-bit multifunction timer), and HRPWM (4-channel high-resolution PWM) synchronized to PCLKC for sub-nanosecond timing precision.
Its clock system combines an 8–24 MHz external crystal oscillator with PLL multiplication, internal HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator-supporting simultaneous operation of multiple peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at configurable frequencies). The device includes ELC (Event Link Controller) to trigger timer, ADC, and PWM actions without CPU intervention, reducing latency in closed-loop control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDGFP#50 | Same RX26T family, identical pinout and peripherals, but with 256 KB code flash and 48 KB SRAM instead of 512 KB/64 KB. | Targeted at cost-optimized motor control where reduced memory footprint suffices for simpler control algorithms or smaller code size. | Select when application firmware fits within 256 KB flash and does not require dual-bank update capability or extended SRAM for complex observer models. |
