Renesas R5F524TEAGFP#31

Overview

R5F524TEAGFP#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), 512 KB on-chip flash, 32 KB SRAM, and dual 12-bit ADC units with 3-channel synchronous sample-and-hold for real-time current sensing in three-phase PMSM/BLDC drives.

For engineers reviewing the R5F524TEAGFP#31 datasheet, R5F524TEAGFP#31 pinout, R5F524TEAGFP#31 application, or R5F524TEAGFP#31 equivalent, key selection considerations include its MTU3-based three-phase complementary PWM with automatic dead-time insertion, CAN 2.0B interface for system-level communication, IEC60730 safety support, and 100-pin LFQFP package with 5-V-tolerant I/Os for robust industrial interfacing.

Technical Context

The R5F524TEAGFP#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling deterministic execution critical for motor control loops. Its clock system integrates PLL, on-chip oscillators (high/low-speed + IWDT-dedicated), and CAC for real-time clock accuracy monitoring - all configurable via independent ICLK/PCLKA/PCLKB domains.

Peripheral integration centers on high-resolution timing: MTU3 provides nine 16-bit channels supporting three-phase complementary PWM ×2 + single-phase complementary ×4 outputs with phase counting, dead-time compensation, and A/D trigger synchronization; GPT adds four 16-bit channels for cascaded 32-bit timing or three-phase + single-phase PWM generation with comparator interlocking.

FAQ

What is the maximum operating frequency and core type of the R5F524TEAGFP#31?

The R5F524TEAGFP#31 operates at a maximum frequency of 80 MHz using the 32-bit RXv2 CPU core, delivering 153.6 DMIPS performance. Its Harvard architecture with 5-stage pipeline and variable-length instruction set ensures deterministic execution for real-time motor control loops. The R5F524TEAGFP#31 also includes an on-chip IEEE754-compliant FPU for efficient floating-point math required in field-oriented control algorithms.

Does the R5F524TEAGFP#31 support IEC60730 Class B functional safety requirements?

Yes, the R5F524TEAGFP#31 includes multiple hardware-assisted features for IEC60730 Class B compliance: self-diagnostic functions for the ADC, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the data operation circuit (DOC), and analog input disconnection detection. These capabilities are documented in the R01DS0257EJ0200 datasheet and enable certified safety routines without external components. The R5F524TEAGFP#31 is widely deployed in safety-certified industrial drives.

What PWM capabilities does the R5F524TEAGFP#31 provide for three-phase motor control?

The R5F524TEAGFP#31 integrates MTU3 with nine 16-bit channels supporting two independent three-phase complementary PWM outputs with automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized operation. It also includes GPT with four 16-bit channels for additional single-phase or cascaded three-phase PWM generation. Both timers support comparator interlocking and A/D trigger generation, enabling precise synchronization between PWM edges and current sampling - essential for low-noise, high-efficiency inverter operation. This capability is central to the R5F524TEAGFP#31's role in PMSM and BLDC motor drives.

How many ADC channels and what sampling capability does the R5F524TEAGFP#31 offer?

The R5F524TEAGFP#31 features three 12-bit S12ADF ADC units totaling 22 channels: unit 0 (5 channels), unit 1 (5 channels), and unit 2 (12 channels). Unit 1 includes a 3-channel synchronous sample-and-hold circuit enabling simultaneous sampling of motor phase currents - critical for vector control. Minimum conversion time is 1.0 µs per channel at 40 MHz ADCLK. Programmable gain amplifiers (1 channel in unit 0, 3 in unit 1) support signal conditioning for low-amplitude current shunt measurements. This ADC architecture is a defining feature of the R5F524TEAGFP#31 in motor control applications.

What package type and pin count does the R5F524TEAGFP#31 use?

The R5F524TEAGFP#31 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package (LFQFP) with 14 mm × 14 mm body size and 0.5 mm pin pitch. It is lead-free and RoHS compliant, with 5-V-tolerant I/Os and an exposed thermal pad for enhanced thermal dissipation in high-power motor control applications. This package matches the pinout of other RX24T Group members like R5F524TCAGFP#31 and R5F524TBAGFP#31, enabling hardware reuse across memory variants. The R5F524TEAGFP#31's pin layout supports full peripheral access including CAN, multiple SCI interfaces, RSPI, and dedicated motor control I/Os.
