Product details
Overview
R5F523T3AGFL#10 from Renesas is a 40-MHz 32-bit RXv2 CPU-based microcontroller optimized for motor control, featuring integrated FPU, 65.6 DMIPS performance, 64-Kbyte flash, 12-Kbyte SRAM, and dual three-phase complementary PWM outputs for inverter drive. It operates from 2.7–5.5 V across −40 to +105°C and integrates a 12-bit ADC with three sample-and-hold circuits, comparator C (3 channels), and IEC60730 safety support.
For engineers reviewing the R5F523T3AGFL#10 datasheet, R5F523T3AGFL#10 pinout, R5F523T3AGFL#10 application, or R5F523T3AGFL#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, MTU3c timer architecture supporting dead-time compensated 3-phase PWM, on-chip CAC for clock accuracy validation, and dual SCI/I²C/RSPI interfaces for real-time motor feedback and host communication.
Technical Context
The R5F523T3AGFL#10 implements the RXv2 core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling single-cycle execution for most operations. Its memory protection unit (MPU), on-chip FPU (IEEE 754 compliant), and 32-bit divider (2-cycle min) support deterministic real-time control loops.
Timing subsystems include dedicated PLL (4–12.5 MHz input), on-chip high-/low-speed oscillators, IWDT with 15-kHz oscillator, and Clock Accuracy Measurement (CAC) circuit. Peripheral clock domains (ICLK/PCLKA/PCLKB/PCLKD) are independently configurable up to 40 MHz, enabling precise synchronization of MTU3c PWM, ADC sampling, and serial interfaces.
