Renesas R5F526TFAGFN#30

Overview

R5F526TFAGFN#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, 48 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase PWM generation with dead-time control.

For engineers reviewing the R5F526TFAGFN#30 datasheet, R5F526TFAGFN#30 pinout, R5F526TFAGFN#30 application, or R5F526TFAGFN#30 equivalent, key selection criteria include its 120 MHz GPTWa/MTU3d timer subsystem for precise motor phase timing, 12-bit S12ADH ADC with simultaneous sampling across 15 channels, HRPWM with 260 ps resolution, Trusted Secure IP Lite encryption, and IEC60730 safety support for Class B compliance.

Technical Context

The R5F526TFAGFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16-register bank save for fast context switching-critical for real-time motor control ISR handling. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at derived frequencies) enabling synchronized high-speed PWM and ADC operation.

Hardware acceleration includes dedicated MTU3d (9-channel 16-bit) and GPTWa (8-channel 16-bit) timers supporting complementary PWM output with automatic dead-time insertion, phase-counting mode, and ELC-triggered A/D conversion start-eliminating CPU intervention during critical motor commutation cycles. The S12ADH ADC operates at 60 MHz ADCLK for 0.9 µs minimum conversion time per channel across two units (7 + 8 channels).
