Product details
Overview
R5F526TFDGFP#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 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 HRPWM timing resolution.
For engineers reviewing the R5F526TFDGFP#50 datasheet, R5F526TFDGFP#50 pinout, R5F526TFDGFP#50 application, or R5F526TFDGFP#50 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across three 12-bit ADC units, Trusted Secure IP Lite encryption, IEC60730-compliant safety features, and event-driven peripheral coordination via ELC - critical for BLDC/PMSM drive design, digital power supplies, and industrial servo systems.
Technical Context
The R5F526TFDGFP#50 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 interrupt-heavy motor control loops. Its clock system supports PLL-synthesized 120 MHz ICLK with independent PCLKA (120 MHz), PCLKC (120 MHz for timers/HRPWM), and PCLKD (60 MHz for ADC) domains to decouple high-speed waveform generation from analog conversion timing.
Peripheral integration centers on deterministic timing: GPTWa (8-channel 32-bit PWM), MTU3d (9-channel 16-bit timer), HRPWM (4-channel sub-260 ps edge placement), and S12ADH (three 12-bit ADC units with sample-and-hold) are all synchronized to dedicated clocks and linked via Event Link Controller (ELC) to eliminate CPU intervention during PWM-triggered ADC sampling, dead-time insertion, and fault response.
