Renesas R5F526TBADFL#30

Overview

R5F526TBADFL#30 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/5-phase complementary PWM generation with 260 ps timing resolution.

For engineers reviewing the R5F526TBADFL#30 datasheet, R5F526TBADFL#30 pinout, R5F526TBADFL#30 application, or R5F526TBADFL#30 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, supports IEC60730 Class B safety compliance, and integrates Trusted Secure IP Lite for AES-128/256 encryption and secure key management.

Technical Context

The R5F526TBADFL#30 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. Its clock system combines an 8–24 MHz external crystal oscillator with PLL synthesis to generate 120 MHz ICLK, while PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) independently drive peripheral domains.

Real-time motor control is enabled by tightly coupled timer subsystems: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) operate synchronously with PCLKC for high-precision PWM, while HRPWM provides 260 ps edge placement resolution on GPTW0–GPTW3 outputs. The ELC allows event-triggered module operation without CPU intervention during sleep modes.
