Product details
Overview
R5F526TBDGFP#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 HRPWM timing resolution.
For engineers reviewing the R5F526TBDGFP#30 datasheet, R5F526TBDGFP#30 pinout, R5F526TBDGFP#30 application, or R5F526TBDGFP#30 equivalent, this MCU is evaluated for real-time motor phase control, IEC60730-compliant safety functions, encrypted firmware updates via AES-256, and simultaneous sampling across three 12-bit A/D units - critical for field-oriented control (FOC) loop execution at ≤1 µs conversion latency.
Technical Context
The R5F526TBDGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 register banks for fast context switching, and integrated FPU compliant with IEEE754 single-precision arithmetic. Its clock system combines an 8–24 MHz external crystal with PLL multiplication to achieve 120 MHz ICLK, while PCLKA/PCLKC operate up to 120 MHz to drive GPTWa timers and HRPWM peripherals synchronously.
Motor control execution relies on tightly coupled timer subsystems: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa delivers 8-channel 32-bit PWM with synchronous start/stop and ELC-triggered A/D conversion; HRPWM refines edge placement of GPTW0–GPTW3 outputs down to 260 ps resolution at 120 MHz - enabling precise gate driver timing for SiC/MOSFET inverters.
