Product details
Overview
R5F526TFDDFM#30 from Renesas is a 120-MHz, 32-bit RXv3 core MCU optimized for motor control and industrial inverter applications, featuring 512 KB code flash, 64 KB SRAM, 16 KB data flash, CAN FD interface, and integrated high-resolution PWM (260 ps min. resolution) with 3-phase/5-phase complementary output capability.
For engineers reviewing the R5F526TFDDFM#30 datasheet, R5F526TFDDFM#30 pinout, R5F526TFDDFM#30 application, or R5F526TFDDFM#30 equivalent, this device supports IEC60730-compliant safety functions, on-chip FPU, Trusted Secure IP Lite encryption (AES-128/256), and simultaneous sampling across three 12-bit A/D units - critical for real-time field-oriented control (FOC) and digital power conversion design.
Technical Context
The R5F526TFDDFM#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU - enabling deterministic motor control math. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120-kHz oscillator for independent timing domains.
Peripheral synchronization uses four distinct clock domains: ICLK (up to 120 MHz for CPU), PCLKA (120 MHz for MTU/GPTW/HRPWM/CAN FD), PCLKB (60 MHz for SCI/RSCI/RIIC), and PCLKD (60 MHz for S12ADH). The ELC enables event-triggered module operation without CPU intervention - essential for low-latency PWM-A/D synchronization in inverter gate drive systems.
