It supports three-phase complementary PWM generation for dual inverter control.

For engineers reviewing the R5F524TEADFP#51 datasheet, R5F524TEADFP#51 pinout, R5F524TEADFP#51 application, or R5F524TEADFP#51 equivalent, key selection considerations include its MTU3-based 3-phase PWM capability with automatic dead-time insertion, IEC60730 safety support for A/D self-diagnostic and disconnection detection, CAN 2.0B compliance, and 100-pin LFQFP package with 5-V tolerant I/O.

Technical Context

The R5F524TEADFP#51 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its memory protection unit (MPU) enforces eight configurable regions with 16-byte granularity for secure execution.

Timing subsystems include dual high-resolution timer units: MTU3 (9 channels, 80 MHz operation) supporting three-phase complementary PWM ×2 + single-phase complementary ×4, and GPT (4 channels) enabling cascaded 32-bit timing and comparator-interlocked PWM negation. Clock accuracy is verified via CAC against main oscillator, PLL, and on-chip oscillators.

FAQ

What is the maximum operating frequency and CPU performance of the R5F524TEADFP#51?

The R5F524TEADFP#51 operates at a maximum frequency of 80 MHz using its RXv2 CPU core, achieving 153.6 DMIPS. It includes a single-precision floating-point unit compliant with IEEE 754, enabling efficient execution of motor control math such as Park/Clarke transforms directly in hardware without software emulation overhead. This performance level is sustained across its full operating voltage range (2.7–5.5 V).

Does the R5F524TEADFP#51 support IEC60730 Class B safety certification?

Yes, the R5F524TEADFP#51 includes multiple hardware features to accelerate IEC60730 Class B compliance: self-diagnostic A/D converter with analog input disconnection detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, RAM test assistance via Data Operation Circuit (DOC), and memory protection unit (MPU). These reduce software validation effort and improve runtime fault coverage for motor control applications.

What PWM capabilities does the R5F524TEADFP#51 offer for inverter control?

The R5F524TEADFP#51 integrates MTU3 (9 channels) and GPT (4 channels) timers optimized for inverter control. MTU3 supports two independent three-phase complementary PWM outputs with automatic dead-time insertion, adjustable duty cycle (0–100%), and phase counting modes. GPT adds comparator-interlocked PWM negation for fast fault response. Together, they enable dual-motor control or redundant inverter leg driving without external logic.

How many ADC channels and what sampling capability does the R5F524TEADFP#51 provide?

The R5F524TEADFP#51 features a 12-bit S12ADF ADC with 22 total channels distributed across three units: unit 0 (5 ch), unit 1 (5 ch), unit 2 (12 ch). Unit 1 includes a 3-channel simultaneous sample-and-hold circuit, allowing true concurrent acquisition for current/voltage vector analysis. Each channel supports programmable sampling time and optional programmable gain amplification (6-step scaling) for direct shunt-resistor signal conditioning.

What communication interfaces are integrated in the R5F524TEADFP#51?

The R5F524TEADFP#51 integrates CAN 2.0B (1 channel, 16 message boxes), three SCI channels supporting asynchronous, clock-synchronous, smart card, simplified SPI/I²C modes, one RIIC interface (400 kbps, SMBus compatible), and one RSPI interface (20 Mbps master/slave). All interfaces are accessible via the Multi-function Pin Controller (MPC), enabling flexible pin assignment and board-level reuse across product variants.
