Product details
Overview
R5F524TAAGFM#31 from Renesas is a 32-bit RXv2 microcontroller optimized for motor control and industrial inverter applications, featuring an 80-MHz CPU core, on-chip FPU compliant with IEEE754, 256-Kbyte code flash, 16-Kbyte SRAM, and integrated 12-bit ADC with 3-channel synchronous sample-and-hold for precise current sensing.
For engineers reviewing the R5F524TAAGFM#31 datasheet, R5F524TAAGFM#31 pinout, R5F524TAAGFM#31 application, or R5F524TAAGFM#31 equivalent, this MCU delivers deterministic PWM timing (three-phase complementary ×2 channels + single-phase complementary ×4), CAN 2.0B interface, IEC60730 safety support, and hardware-assisted dead-time compensation - critical for field-oriented control (FOC) and BLDC motor drives.
Technical Context
The R5F524TAAGFM#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 153.6 DMIPS at 80 MHz. It integrates dual high-precision timer units: MTU3 (9×16-bit channels) supporting three-phase PWM with automatic dead-time insertion, and GPT (4×16-bit channels) for cascaded 32-bit timing and comparator-interlocked PWM negation.
Its analog subsystem includes three independent 12-bit ADC units (5/5/12 channels), with unit 1 featuring 3-channel simultaneous sampling, programmable gain amplifiers (2.0×–4.444×), and self-diagnostic functions aligned to IEC60730 Class B. Clock management supports PLL-synthesized 80-MHz ICLK, dedicated PCLKA for timers, and CAC for real-time oscillator accuracy monitoring.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F524TBADFP#31 | 100-pin LFQFP, 256-Kbyte flash, 32-Kbyte RAM, full MTU3/GPT/POE3A support - adds 20 extra GPIOs and full 9-channel MTU3 capability | Required for designs needing >48 GPIOs, full 3-phase ×3 PWM, or simultaneous use of all 3 ADC units with 12-channel unit 2 | Select when board layout accommodates larger package and application demands extended timer/ADC resources beyond R5F524TAAGFM#31's 64-pin constraints |
| STM32G474RET6 | ARM Cortex-M4F @ 170 MHz, 512-Kbyte flash, 128-Kbyte RAM, 12-bit ADC @ 3.6 MSPS, advanced timers with dead-time control - higher clock speed but no integrated CAN PHY | Better suited for high-throughput sensor fusion or USB-C PD control; requires external CAN transceiver and lacks IEC60730 hardware acceleration blocks | Prefer when leveraging ARM ecosystem tools or needing >100-MHz compute headroom; verify external component count impact on BOM cost and safety certification scope |
Compared with R5F524TAAGFM#31, R5F524TBADFP#31 offers expanded I/O and timer resources in a larger package, while STM32G474RET6 trades Renesas-specific motor control peripherals and safety hardware for broader ARM software compatibility and higher raw throughput - selection hinges on pin count, safety certification burden, and existing toolchain investment.

FAQ
What is the maximum PWM frequency supported by R5F524TAAGFM#31?
R5F524TAAGFM#31 supports up to 80-MHz timer clock (PCLKA) for MTU3 and GPT modules. With 16-bit resolution, this enables base PWM frequencies up to 1.22 MHz (80 MHz ÷ 65,536), though practical motor control usage typically targets 10–20 kHz for inverter switching. The R5F524TAAGFM#31's hardware dead-time insertion and complementary output modes ensure clean, jitter-free waveforms at these frequencies without CPU intervention.
Does R5F524TAAGFM#31 include a CAN transceiver or require an external one?
R5F524TAAGFM#31 integrates the RSCAN CAN controller compliant with ISO11898-1 but does not include a physical-layer transceiver. An external CAN transceiver (e.g., TJA1042, SN65HVD230) must be used to drive the CANH/CANL differential bus lines. This separation allows design flexibility in selecting transceivers with specific ESD ratings, slew-rate control, or standby modes appropriate for the target application environment.
How many ADC channels can perform simultaneous sampling on R5F524TAAGFM#31?
R5F524TAAGFM#31 supports true simultaneous sampling on up to 3 channels within S12ADF unit 1, enabled by its dedicated 3-channel sample-and-hold circuit. Units 0 and 2 do not support simultaneous sampling. This 3-channel concurrency is hardware-triggered and essential for capturing motor phase currents without time skew during field-oriented control calculations in the R5F524TAAGFM#31.
Is the FPU in R5F524TAAGFM#31 IEEE754-compliant and usable in safety-critical code?
Yes, the R5F524TAAGFM#31's on-chip FPU fully complies with IEEE754 single-precision (32-bit) standards, including handling of denormals, infinities, and NaNs. It is qualified for use in IEC60730 Class B applications when combined with MPU-protected memory regions and DOC-based runtime integrity checks - all supported features in the R5F524TAAGFM#31's safety architecture.
What debugging interface does R5F524TAAGFM#31 support and what tools are compatible?
R5F524TAAGFM#31 supports the FINE interface for on-chip debugging via the Renesas E1/E20 emulators. It is fully compatible with Renesas CS+ IDE and e2 studio, enabling real-time trace, breakpoint debugging, flash programming, and register-level inspection. No JTAG adapter is required - the FINE interface uses a 2-pin serial connection (FINED and VDD), reducing debug footprint versus traditional SWD/JTAG solutions on the R5F524TAAGFM#31.
