Renesas R5F524TAAGFN#31

Overview

R5F524TAAGFN#31 from Renesas is a 32-bit RXv2 microcontroller optimized for motor control and industrial inverter applications, featuring an 80 MHz CPU core delivering 153.6 DMIPS, on-chip 256 KB flash, 16 KB SRAM, 8 KB data flash, and integrated 12-bit ADC with 3-channel synchronous sample-and-hold for precise current sensing in three-phase PMSM/BLDC drives.

For engineers reviewing the R5F524TAAGFN#31 datasheet, R5F524TAAGFN#31 pinout, R5F524TAAGFN#31 application, or R5F524TAAGFN#31 equivalent, this device is evaluated for real-time PWM timing accuracy, IEC60730-compliant self-diagnostic capability, CAN bus integration, and high-resolution analog acquisition in compact 80-pin LFQFP (0.5 mm pitch) packages - critical for space-constrained motor control designs.

Technical Context

The R5F524TAAGFN#31 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 5-stage pipeline, and variable-length instruction set, enabling deterministic execution for motor control algorithms. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators, and CAC for real-time clock accuracy monitoring - essential for synchronized PWM and ADC sampling.

It features dual timer subsystems: MTU3 (9×16-bit channels) supporting three-phase complementary PWM ×2 + single-phase complementary ×4 with automatic dead-time insertion, and GPT (4×16-bit channels) for cascaded 32-bit timing and comparator-interlocked PWM negation - both operating at 80 MHz PCLKA to meet tight inverter gate drive timing requirements.

FAQ

What is the maximum operating frequency and core type of the R5F524TAAGFN#31?

The R5F524TAAGFN#31 operates at a maximum frequency of 80 MHz using the 32-bit RXv2 CPU core. It delivers 153.6 DMIPS performance and includes a single-precision IEEE 754 floating-point unit (FPU), 5-stage pipeline, and variable-length instruction set - all optimized for deterministic execution of motor control algorithms. This core architecture is confirmed in the R01DS0257EJ0200 datasheet Rev.2.00, Section 1.1.

Does the R5F524TAAGFN#31 support IEC60730 Class B compliance out of the box?

Yes, the R5F524TAAGFN#31 includes built-in hardware features for IEC60730 Class B compliance: ADC disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, memory protection unit (MPU), and data operation circuit (DOC) for RAM testing. These are documented in Section 1.1 and Section 1.4 of the R01DS0257EJ0200 datasheet.

How many PWM channels and what types are supported by the R5F524TAAGFN#31?

The R5F524TAAGFN#31 supports nine 16-bit MTU3 channels and four 16-bit GPT channels. It can generate three-phase complementary PWM ×2 channels plus single-phase complementary PWM ×4 channels - or alternatively three-phase ×3 + single-phase ×1 - all with hardware dead-time insertion and A/D trigger synchronization. This capability is detailed in Table 1.1 and Section 1.1 of the R01DS0257EJ0200 datasheet.

What is the ADC configuration of the R5F524TAAGFN#31, and does it support simultaneous sampling?

The R5F524TAAGFN#31 integrates three 12-bit S12ADF units: two with 5 channels each and one with 12 channels. Unit 1 includes a 3-channel synchronous sample-and-hold circuit enabling true simultaneous sampling - critical for three-phase current measurement in motor control. Minimum conversion time is 1.0 µs at 40 MHz ADCLK, as specified in Section 1.1 and Table 1.2 of the R01DS0257EJ0200 datasheet.

What package type and pin count does the R5F524TAAGFN#31 use?

The R5F524TAAGFN#31 uses an 80-pin LFQFP package (PLQP0080KB-B) with 14 × 14 mm body size and 0.5 mm pitch. It supports –40 to +85°C operation and features 5-V tolerant I/O, open-drain capability, and programmable drive strength. This package variant is explicitly listed in Table 1.3 and Figure 1.1 of the R01DS0257EJ0200 datasheet Rev.2.00.
