Product details
Overview
R5F524T8AGFN#31 from Renesas is a 32-bit RXv2 core MCU 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 flash, 16 KB SRAM, 8 KB data flash, and dual 12-bit ADC units with 3-channel simultaneous sampling for shunt-based current sensing.
For engineers reviewing the R5F524T8AGFN#31 datasheet, R5F524T8AGFN#31 pinout, R5F524T8AGFN#31 application, or R5F524T8AGFN#31 equivalent, this device delivers deterministic PWM timing, IEC60730-compliant self-test features, CAN interface, and hardware-accelerated motor control peripherals - critical for servo drives, BLDC inverters, and industrial PLC I/O modules.
Technical Context
The R5F524T8AGFN#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling ultra-compact code and fast interrupt response. It integrates MTU3 (9-channel 16-bit timer) supporting three-phase complementary PWM ×2 channels with automatic dead-time insertion and phase counting mode - directly targeting field-oriented control (FOC) execution.
Its clock system includes PLL (4–12.5 MHz input), on-chip oscillators (high/low-speed + IWDT-dedicated 15 kHz), and CAC for real-time clock accuracy monitoring. The peripheral set is tailored for motor systems: dual S12ADF ADC units (5+5+12 channels), programmable gain amplifiers (1+3 channels), comparator C (4 channels), and 8-bit DAa (2 channels) for reference voltage generation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F524TAADFN#31 | Same package (LFQFP-80), but 256 KB flash, 16 KB RAM, Chip Version A - lacks CAN module and POE3A support. | Targeted at non-CAN motor control (e.g., fan drivers) where larger code space is needed but automotive-grade bus interface is unnecessary. | Select when CAN is not required and higher flash capacity justifies cost premium over R5F524T8AGFN#31. |
| R5F523T7ADFP#31 | 100-pin LFQFP, 64 KB flash, 16 KB RAM, Chip Version A - includes CAN, but lower PWM channel count (MTU3: 6 channels vs. 9) and no simultaneous 3-channel ADC sampling. | Suitable for simpler inverter topologies (e.g., single-motor drives) where reduced peripheral count meets functional requirements. | Choose for cost-sensitive designs needing CAN but not advanced FOC features like dual 3-phase PWM or synchronous ADC sampling. |
Compared with R5F524T8AGFN#31, R5F524TAADFN#31 trades CAN and POE3A for more flash, while R5F523T7ADFP#31 offers CAN in a larger package but omits key motor control accelerators - making R5F524T8AGFN#31 the optimal balance of integration, package size, and FOC-specific hardware for compact inverters.
