Renesas R5F524TBAGFP#31

Overview

R5F524TBAGFP#31 from Renesas Electronics is a 32-bit RXv2 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 80 MHz (153.6 DMIPS), featuring integrated FPU (IEEE 754 single-precision), 256 KB on-chip code flash, 32 KB SRAM, and dual 12-bit A/D converters with 3-channel simultaneous sampling for shunt-based current sensing.

For engineers reviewing the R5F524TBAGFP#31 datasheet, R5F524TBAGFP#31 pinout, R5F524TBAGFP#31 application, or R5F524TBAGFP#31 equivalent, this MCU delivers deterministic PWM timing (MTU3/GPT), CAN 2.0B compliance, IEC60730 safety support, and hardware-accelerated motor control peripherals - critical for servo drives, HVAC blowers, and industrial PMSM/BLDC inverters.

Technical Context

The R5F524TBAGFP#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling ultra-compact code and fast interrupt response. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators (low/high-speed + IWDT-dedicated 15 kHz), and CAC for real-time clock accuracy monitoring.

Motor control execution relies on tightly coupled peripherals: MTU3 provides three-phase complementary PWM ×2 channels with automatic dead-time insertion and phase counting, while GPT supports single-phase complementary ×4 or three-phase ×1 + single-phase ×1 configurations, both synchronized to PCLKA at 80 MHz.

FAQ

What is the maximum operating frequency and CPU performance of the R5F524TBAGFP#31?

The R5F524TBAGFP#31 operates at a maximum frequency of 80 MHz using its RXv2 32-bit CPU core, delivering 153.6 DMIPS of processing performance. This enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless BLDC commutation with minimal latency. The R5F524TBAGFP#31 achieves this performance with zero-wait-state access to 32 KB SRAM and optimized instruction pipelining.

Does the R5F524TBAGFP#31 support IEC60730 Class B compliance for safety-critical motor control?

Yes, the R5F524TBAGFP#31 includes multiple hardware-assisted IEC60730 Class B compliance features: self-diagnostic ADC disconnection detection, RAM test support via the Data Operation Circuit (DOC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, memory protection unit (MPU), and register write protection. These features reduce software certification burden and are documented in Renesas Application Note R01AN2379EU0100. The R5F524TBAGFP#31 leverages these capabilities to meet functional safety requirements in industrial inverters.

What PWM and timer resources does the R5F524TBAGFP#31 provide for inverter gate driving?

The R5F524TBAGFP#31 integrates two dedicated motor control timer modules: MTU3 (9 channels, 80 MHz) supporting three-phase complementary PWM ×2 channels with automatic dead-time insertion, and GPT (4 channels, 80 MHz) supporting single-phase complementary ×4 or three-phase ×1 + single-phase ×1 configurations. Both modules synchronize to PCLKA at 80 MHz and support hardware-triggered ADC starts, phase counting, and comparator interlocking - essential for precise gate driving in IGBT and SiC-based inverters. The R5F524TBAGFP#31 also includes POE3b/POE3A for hardware-controlled PWM output disable during fault conditions.

How many A/D converter channels and what sampling capability does the R5F524TBAGFP#31 offer?

The R5F524TBAGFP#31 features three 12-bit S12ADF units totaling 22 channels: unit 0 (5 channels), unit 1 (5 channels), and unit 2 (12 channels). Unit 1 includes a 3-channel simultaneous sample-and-hold circuit for shunt-based current sensing, enabling synchronized acquisition across all three motor phases with <10 ns skew. Each channel supports programmable sampling time, group scan priority, and self-diagnostic functions. The R5F524TBAGFP#31 also integrates a programmable gain amplifier (1 channel in unit 0, 3 in unit 1) with six selectable gains to condition low-level shunt signals prior to conversion.

Is the R5F524TBAGFP#31 pin-compatible with other RX24T Group MCUs in the same package?

Yes, the R5F524TBAGFP#31 uses the 100-pin LFQFP (PLQP0100KB-B) package and shares identical pinout and electrical characteristics with other RX24T Group devices in that footprint, including R5F524TEAGFP#31, R5F524TCAGFP#31, and R5F524TAAGFP#31. All share the same power, clock, reset, and peripheral pin assignments - enabling hardware reuse across memory variants. However, peripheral enablement (e.g., CAN, POE3A) varies by chip version (A/B), so firmware must validate module availability per part number. The R5F524TBAGFP#31 is fully pin-compatible with these variants.
