Product details
Overview
R5F524TAADFK#31 from Renesas is a 32-bit RXv2 core MCU optimized for motor control and industrial inverter applications, operating at 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 - deployed in HVAC compressors and servo drive modules.
For engineers reviewing the R5F524TAADFK#31 datasheet, R5F524TAADFK#31 pinout, R5F524TAADFK#31 application, or R5F524TAADFK#31 equivalent, key selection considerations include its 256-KB flash / 16-KB SRAM configuration, 100-pin LFQFP 0.5-mm pitch package, IEC60730 safety support, and dedicated hardware acceleration for real-time PWM dead-time compensation and A/D trigger synchronization.
Technical Context
The R5F524TAADFK#31 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 32×32→64-bit multiplier, and 32-bit divider (2-cycle min), enabling deterministic floating-point motion control algorithms. Its clock system integrates PLL, on-chip high/low-speed oscillators, and CAC for real-time clock accuracy monitoring - all synchronized to 80-MHz ICLK and configurable peripheral clocks (PCLKA/B/D).
Hardware peripherals are tightly coupled for motor control: MTU3 provides nine 16-bit timer channels supporting three-phase complementary PWM ×2 + single-phase complementary ×4, with automatic dead-time insertion, phase counting, and A/D start triggering; GPT adds four 16-bit channels for cascaded 32-bit timing or three-phase + single-phase PWM combinations, while POE3A enables software-controlled high-impedance state switching of waveform outputs during fault conditions.
