Product details
Overview
R5F524TCAGFP#31 from Renesas is a 32-bit RXv2 core MCU optimized for motor control and industrial inverter applications, operating at 80 MHz (153.6 DMIPS), featuring integrated FPU (IEEE754 single-precision), 384 KB on-chip code flash, 32 KB SRAM, and dual 12-bit ADC units with 3-channel simultaneous sampling - deployed in HVAC compressors, servo drives, and industrial PMSM/BLDC inverters.
For engineers reviewing the R5F524TCAGFP#31 datasheet, R5F524TCAGFP#31 pinout, R5F524TCAGFP#31 application, or R5F524TCAGFP#31 equivalent, key selection considerations include its MTU3-based three-phase complementary PWM (×2 channels), GPT-based single-phase complementary PWM (×4 channels), CAN interface (ISO11898-1), IEC60730 safety support, and 100-pin LFQFP 0.5 mm pitch package with 5-V tolerant I/O.
Technical Context
The R5F524TCAGFP#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling deterministic real-time execution at 80 MHz. Its MTU3 timer unit delivers hardware-accelerated three-phase PWM with automatic dead-time insertion and phase counting, while the GPTB module supports cascaded 32-bit timing and comparator-interlocked PWM negation control.
On-chip peripherals are clocked via dedicated domains: ICLK (80 MHz for CPU), PCLKA (80 MHz for MTU3/GPT), PCLKB (40 MHz for RIIC/SCI), and PCLKD (40 MHz for S12ADF). The MCU integrates dual 12-bit ADC units (5+5+12 channels) with per-channel sampling time control, programmable gain amplifiers (1+3 channels), and self-diagnostic functions compliant with IEC60730 Class B requirements.

FAQ
What is the maximum operating frequency and CPU performance of the R5F524TCAGFP#31?
The R5F524TCAGFP#31 operates at a maximum frequency of 80 MHz using its RXv2 CPU core, delivering 153.6 DMIPS of processing performance. It supports single-cycle instruction execution, on-chip FPU (IEEE754 single-precision), and DSP instructions including 32-bit MAC and 16-bit MSU - enabling real-time execution of complex motor control algorithms such as field-oriented control without external co-processors. This performance level is fully sustained across its –40°C to +85°C operating range.
Does the R5F524TCAGFP#31 support IEC60730 Class B functional safety certification?
Yes, the R5F524TCAGFP#31 includes multiple hardware features to support IEC60730 Class B compliance: memory protection unit (MPU), register write protection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, self-diagnostic ADC functions, and analog input disconnection detection. These capabilities reduce external safety component requirements and simplify certification documentation for industrial motor drives and HVAC systems using the R5F524TCAGFP#31.
What PWM configurations does the R5F524TCAGFP#31 support for three-phase inverter control?
The R5F524TCAGFP#31 supports three-phase inverter control via its MTU3 unit, which provides two independent channels of three-phase complementary PWM output with automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized PWM mode. Each channel outputs six waveform signals (U/V/W + inverted), with hardware-triggered A/D start capability and fault shutdown via POE3b. This eliminates software timing jitter and enables sub-microsecond commutation timing critical for PMSM/BLDC applications using the R5F524TCAGFP#31.
How many ADC channels and what sampling capabilities does the R5F524TCAGFP#31 provide?
The R5F524TCAGFP#31 integrates three 12-bit S12ADF ADC units totaling 22 channels: two units with 5 channels each (units 0 and 1), and one unit with 12 channels (unit 2). Unit 1 includes a 3-channel simultaneous sample-and-hold circuit for shunt-based current sensing, with per-channel programmable sampling time and group scan priority control. Minimum conversion time is 1.0 µs per channel at 40 MHz ADCLK, and programmable gain amplifiers (1+3 channels) support direct connection to low-level sensor signals - all critical for precision motor control using the R5F524TCAGFP#31.
What package type and pin count does the R5F524TCAGFP#31 use?
The R5F524TCAGFP#31 uses a 100-pin LFQFP package (PLQP0100KB-B) with 14 × 14 mm body size and 0.5 mm pin pitch. It features 80 general-purpose I/O pins, of which 60 support open-drain operation and 2 are 5-V tolerant. The package is lead-free and rated for industrial temperature range (–40°C to +85°C), matching pinout compatibility with other RX24T Group 100-pin variants like R5F524TEAGFP#31 - enabling drop-in flash capacity upgrades without PCB redesign for the R5F524TCAGFP#31.
