Product details
Overview
R5F524TCADFP#31 from Renesas is a 32-bit RXv2 microcontroller optimized for motor control and industrial inverter applications, featuring an 80-MHz CPU core delivering 153.6 DMIPS, on-chip single-precision FPU (IEEE 754 compliant), 384-Kbyte code flash, 32-Kbyte SRAM, and integrated 12-bit ADC with 3-channel synchronous sample-and-hold for simultaneous current sensing.
For engineers reviewing the R5F524TCADFP#31 datasheet, R5F524TCADFP#31 pinout, R5F524TCADFP#31 application, or R5F524TCADFP#31 equivalent, key selection considerations include its MTU3-based three-phase complementary PWM generation (2 channels), GPT-based PWM flexibility (4 channels), CAN 2.0B interface, IEC60730 safety support, and 100-pin LFQFP-0.5mm package with 81 general-purpose I/Os including 5-V tolerant and open-drain options.
Technical Context
The R5F524TCADFP#31 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) supporting eight configurable regions. Its clock system integrates PLL, on-chip high/low-speed oscillators, and CAC for real-time clock accuracy monitoring across ICLK (80 MHz), PCLKA (80 MHz for MTU3/GPT), and PCLKD (40 MHz for ADC).
Motor control execution relies on tightly coupled peripherals: MTU3 provides 9-channel 16-bit timers with dead-time compensation, phase counting, and A/D trigger synchronization; GPT delivers 4-channel PWM with cascaded 32-bit operation and comparator interlocking; and S12ADF includes three independent 12-bit ADC units (5+5+12 channels) with programmable gain amplifiers (1+3 channels) and self-diagnostic functions per IEC60730.
