Product details
Overview
R5F526TFBGNE#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual 12-bit D/A converters. It targets real-time closed-loop motor drive systems requiring IEC60730 functional safety compliance.
For engineers reviewing the R5F526TFBGNE#30 datasheet, R5F526TFBGNE#30 pinout, R5F526TFBGNE#30 application, or R5F526TFBGNE#30 equivalent, key selection criteria include 120 MHz PWM timing precision, simultaneous 3-phase/5-phase complementary PWM generation, integrated HRPWM for gate driver timing alignment, CAN FD interface for real-time diagnostics, and on-chip Trusted Secure IP Lite for firmware integrity protection.
Technical Context
The R5F526TFBGNE#30 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 motor control interrupt service routines. Its clock system supports independent PCLKA (120 MHz), PCLKC (120 MHz for timer/HRPWM reference), and PCLKD (60 MHz for A/D) domains to decouple high-speed PWM timing from analog conversion timing.
It integrates three dedicated motor control peripherals: MTU3d (9-channel 16-bit timer with 3-phase complementary PWM and dead-time auto-insertion), GPTWa (8-channel 32-bit general PWM timer supporting single-/3-/5-phase modes), and HRPWM (4-channel sub-260 ps edge placement for precise gate driver synchronization). All operate under ELC event linking to eliminate CPU intervention during waveform updates.
