Product details
Overview
R5F526TFCGFN#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 R5F526TFCGFN#30 datasheet, R5F526TFCGFN#30 pinout, R5F526TFCGFN#30 application, or R5F526TFCGFN#30 equivalent, key selection considerations include its dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated HRPWM circuit for high-precision inverter gate drive timing.
Technical Context
The R5F526TFCGFN#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and optional big/little-endian data handling. It integrates a memory protection unit (MPU) supporting eight configurable protection areas down to 16-byte granularity and Trusted Memory (TM) functionality to prevent unauthorized read access to protected code flash regions.
Its real-time control subsystem includes three synchronized timer families: MTU3d (16-bit × 9 channels), GPTWa (32-bit × 8 channels), and HRPWM (4-channel high-resolution extension of GPTW), all clocked from PCLKC up to 120 MHz and coordinated via the Event Link Controller (ELC) to enable interrupt-free, event-triggered peripheral chaining - critical for deterministic motor commutation sequences.
