Renesas R5F524T8AGFP#31

Overview

R5F524T8AGFP#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 FPU (IEEE 754 single-precision), 128 KB on-chip code flash, 16 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It delivers three-phase complementary PWM ×2 channels + single-phase complementary PWM ×4 channels via MTU3 and GPT timers, and supports CAN (ISO 11898-1) for real-time fieldbus communication in servo drives.

For engineers reviewing the R5F524T8AGFP#31 datasheet, R5F524T8AGFP#31 pinout, R5F524T8AGFP#31 application, or R5F524T8AGFP#31 equivalent, this MCU is selected for high-accuracy motor timing, IEC60730-compliant self-diagnostic A/D conversion, and deterministic PWM dead-time control - critical for BLDC/PMSM inverter designs requiring <1.0 µs ADC conversion time and synchronized 3-channel sample-and-hold.

Technical Context

The R5F524T8AGFP#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators (low/high-speed, IWDT-dedicated 15 kHz), and CAC for real-time clock accuracy monitoring across ICLK (80 MHz), PCLKA (80 MHz for MTU3/GPT), and PCLKD (40 MHz for S12AD).

Peripheral integration centers on motor control: MTU3 provides nine 16-bit timer channels with phase counting, dead-time compensation, and reset-synchronized PWM; GPT adds four 16-bit channels supporting cascaded 32-bit operation and comparator interlocking. The S12ADF A/D converter includes three independent units (5/5/12 channels), programmable gain amplifiers (1+3 channels), and analog disconnection detection per IEC60730.
