Renesas R5F524T8ADFM#11

Overview

R5F524T8ADFM#11 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 single-precision FPU (IEEE 754 compliant), 128-Kbyte code flash, 16-Kbyte SRAM, and integrated 12-bit ADC with 3-channel simultaneous sampling capability.

For engineers reviewing the R5F524T8ADFM#11 datasheet, R5F524T8ADFM#11 pinout, R5F524T8ADFM#11 application, or R5F524T8ADFM#11 equivalent, key selection criteria include its 80-MHz three-phase complementary PWM generation (MTU3 × 2 channels), CAN 2.0B interface, IEC60730 safety support, and 64-pin LFQFP package with 48 general-purpose I/Os and 5-V tolerance on two pins.

Technical Context

The R5F524T8ADFM#11 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip MPU for memory protection. Its clock system integrates PLL (4–12.5 MHz input), main oscillator (1–20 MHz), and dedicated IWDT oscillator (15 kHz), enabling independent clock domains: ICLK at 80 MHz for CPU, PCLKA at 80 MHz for MTU3/GPT, and PCLKD at 40 MHz for S12AD.

It supports deterministic real-time motor control via dual 16-bit MTU3 units (9 channels total) with dead-time compensation, phase counting, and A/D trigger synchronization, plus GPTB (4 channels) for cascaded 32-bit timing and comparator-interlocked PWM negation - all coordinated through the DTC for zero-CPU-overhead data movement.

FAQ

What is the maximum operating frequency and core type of the R5F524T8ADFM#11?

The R5F524T8ADFM#11 operates at a maximum frequency of 80 MHz using the 32-bit RXv2 CPU core, achieving 153.6 DMIPS performance. It incorporates a Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU compliant with IEEE 754 single-precision standard - all confirmed in the R01DS0257EJ0200 Rev.2.00 datasheet, Section 1.1.

Does the R5F524T8ADFM#11 support simultaneous sampling across multiple ADC channels?

Yes, the R5F524T8ADFM#11 supports true simultaneous sampling of up to three channels via the S12ADF unit 1, which includes a dedicated 3-channel sample-and-hold circuit. This capability is explicitly documented in Section 1.1 and Figure 1.2 of the R01DS0257EJ0200 datasheet and is essential for accurate three-phase current measurement in motor control applications.

What package type and pin count does the R5F524T8ADFM#11 use?

The R5F524T8ADFM#11 uses the PLQP0064KB-C package: a 64-pin LFQFP with 10 × 10 mm body size and 0.5 mm pitch. This is confirmed in Table 1.3 (List of Products) and Figure 1.1 (Part Number Decoding) of the R01DS0257EJ0200 datasheet, where "FM" denotes the 64-pin variant.

Which safety standards does the R5F524T8ADFM#11 support for industrial applications?

The R5F524T8ADFM#11 includes built-in features supporting IEC60730 Class B compliance, including ADC analog input disconnection detection, clock frequency accuracy measurement (CAC), RAM test assistance via DOC, and independent watchdog timer (IWDT) with dedicated 15-kHz oscillator - all detailed in Section 1.1 and Section 1.4 of the R01DS0257EJ0200 datasheet.

How many PWM output channels with complementary operation does the R5F524T8ADFM#11 provide?

The R5F524T8ADFM#11 provides three-phase complementary PWM output across two independent MTU3 channels (totaling six active outputs plus six inverted outputs), with automatic dead-time insertion and phase counting mode - as specified in Section 1.1 (Table 1.1) and confirmed in the block diagram (Figure 1.2) of the R01DS0257EJ0200 datasheet.
