Overview
R5F526TFAGND#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, 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 complementary PWM generation for inverter drives.
For engineers reviewing the R5F526TFAGND#30 datasheet, R5F526TFAGND#30 pinout, R5F526TFAGND#30 application, or R5F526TFAGND#30 equivalent, this MCU delivers deterministic real-time control with 260 ps high-resolution PWM timing, IEC60730-compliant safety features, and dual-bank flash for seamless firmware updates in industrial motor drives and digital power supplies.
Technical Context
The R5F526TFAGND#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 interrupt-heavy motor control loops. It integrates dedicated peripherals including GPTWa (8-channel 32-bit PWM timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel high-resolution PWM) synchronized to PCLKC at up to 120 MHz.
Its clock system combines an 8–24 MHz external crystal oscillator with PLL multiplication, internal HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator. The device supports simultaneous sampling across three 12-bit A/D converter units (S12ADH) and includes Trusted Secure IP Lite for AES-128/256 encryption and true random number generation.
