Product details
Overview
R5F524TAAGFF#31 from Renesas Electronics 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 (IEEE754 compliant), 256 KB flash, 16 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It integrates dual 12-bit ADC units (5+5 channels) with 3-channel simultaneous sample-and-hold, three-phase complementary PWM ×2 channels via MTU3, and CAN 2.0B interface compliant with ISO11898-1.
For engineers reviewing the R5F524TAAGFF#31 datasheet, R5F524TAAGFF#31 pinout, R5F524TAAGFF#31 application, or R5F524TAAGFF#31 equivalent, this device supports real-time motor phase current sensing, high-resolution PWM timing control, IEC60730 safety diagnostics, and deterministic communication in compact 80-pin LQFP (0.65 mm pitch) packaging - critical for space-constrained industrial drives and servo controllers.
Technical Context
The R5F524TAAGFF#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its clock system includes PLL (4–12.5 MHz input), on-chip high/low-speed oscillators, and dedicated IWDT oscillator (15 kHz), with independent clock domains: ICLK (80 MHz for CPU), PCLKA (80 MHz for MTU3/GPT), PCLKB (40 MHz for peripherals), and ADCLK (40 MHz for S12ADF).
Peripheral integration centers on motor control: MTU3 provides nine 16-bit timer channels supporting three-phase complementary PWM with automatic dead-time insertion, phase counting, and A/D trigger synchronization; GPT delivers four 16-bit channels for single-phase complementary or cascaded 32-bit operation; and the dual S12ADF ADC units support group-scan priority, programmable gain amplifiers (6-step scaling), and analog disconnection detection per IEC60730.
