Product details
Overview
R5F524T8ADFM#31 from Renesas Electronics is a 32-bit RXv2 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 80 MHz (153.6 DMIPS), featuring integrated 12-bit ADC with 3-channel synchronous sample-and-hold, dual 8-bit DACs, CAN interface (ISO 11898-1), and three-phase complementary PWM generation across two MTU3 channels.
For engineers reviewing the R5F524T8ADFM#31 datasheet, R5F524T8ADFM#31 pinout, R5F524T8ADFM#31 application, or R5F524T8ADFM#31 equivalent, key selection considerations include its 64-pin LFQFP package, 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, IEC60730 safety support, and dedicated hardware for real-time motor phase control with dead-time compensation and POE3A output enable functionality.
Technical Context
The R5F524T8ADFM#31 implements the RXv2 CPU core with IEEE 754-compliant single-precision FPU, 32-bit multiply-accumulate, and fast interrupt response-enabling deterministic execution in closed-loop motor control. Its clock system integrates PLL, on-chip oscillators (including IWDT-dedicated 15 kHz source), and CAC for real-time clock accuracy monitoring.
Peripheral architecture centers on high-resolution timing: MTU3 supports 80 MHz three-phase complementary PWM with automatic dead-time insertion and A/D trigger synchronization, while GPTB provides additional PWM and phase-counting capability. The S12ADF ADC includes programmable gain amplifiers (1+3 channels), group-scan priority, and analog disconnection detection compliant with IEC60730 Class B requirements.
