Renesas R5F562TAADFH#V1

Overview

R5F562TAADFH#V1 from Renesas Electronics is a 100-MHz 32-bit RX CPU-based microcontroller designed for motor control and industrial inverter applications. It integrates dual 12-bit ADC units with sample-and-hold and programmable gain amplifiers, 8-channel MTU3 for three-phase complementary PWM, CAN 2.0B interface (32 mailboxes), 16 KB SRAM, 256 KB flash, and operates from a 4.0–5.5 V supply across –40°C to +85°C.

For engineers reviewing the R5F562TAADFH#V1 datasheet, R5F562TAADFH#V1 pinout, R5F562TAADFH#V1 application, or R5F562TAADFH#V1 equivalent, key selection criteria include its 100-MHz PWM timing resolution (312 ps delay control), IEC 60730-compliant self-diagnostic ADC and CRC unit, integrated POE3 for fast fault shutdown, and support for simultaneous 7-channel sampling across three ADC units.

Technical Context

The R5F562TAADFH#V1 belongs to the RX62T Group and implements a CISC Harvard architecture with 5-stage pipeline, single-precision IEEE-754 FPU, and memory protection unit (MPU). Its clock system supports PLL-based 100-MHz ICLK and configurable PCLK up to 50 MHz, enabling synchronized operation of CPU, MTU3, GPT, and peripheral modules.

It features hardware-accelerated motor control functions: MTU3 provides two independent three-phase complementary PWM outputs with automatic dead-time insertion and phase-counting mode; GPTa enables precise PWM edge delay (≤312 ps at 100 MHz); and POE3 triggers high-impedance state on MTU3/GPT pins via comparator detection, oscillation stoppage, or software-critical for IEC 60730-compliant safety shutdown.

FAQ

What is the maximum operating frequency and CPU performance of the R5F562TAADFH#V1?

The R5F562TAADFH#V1 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance. It uses the 32-bit RX CPU core with a 5-stage pipeline, single-precision IEEE-754 floating-point unit, and hardware multiplier/divider. This performance level enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless position estimation without external co-processors-making the R5F562TAADFH#V1 ideal for demanding inverter applications.

Does the R5F562TAADFH#V1 support IEC 60730 functional safety requirements?

Yes, the R5F562TAADFH#V1 includes multiple hardware features certified for IEC 60730 Class B compliance: an independent watchdog timer (IWDT) with dedicated 125-kHz LOCO clock, CRC calculation unit for memory and data transfer integrity checking, self-diagnostic ADC with internal reference voltage generation, oscillation stop detection, and low-voltage detection (LVD). These features are implemented in silicon and documented in Renesas' IEC 60730 safety manual-enabling R5F562TAADFH#V1-based designs to achieve full certification without external safety monitors.

What ADC capabilities does the R5F562TAADFH#V1 provide for motor current sensing?

The R5F562TAADFH#V1 integrates two independent 12-bit S12ADA units (4 channels each) and one 10-bit ADA unit (12 channels), supporting simultaneous sampling across 7 channels. Each 12-bit unit includes three programmable-gain amplifier (PGA) channels (11 gain steps: 2× to 13.3×) and window comparators-allowing direct shunt-based current sensing with high SNR and overcurrent protection. The common sample-and-hold circuit ensures synchronized capture of phase currents and DC-link voltage, essential for accurate FOC execution in the R5F562TAADFH#V1.

How does the R5F562TAADFH#V1 implement hardware-based fault protection for motor drives?

The R5F562TAADFH#V1 implements hardware fault protection via Port Output Enable 3 (POE3), which monitors five dedicated inputs (POE0, POE4, POE8, POE10, POE11) to instantly force MTU3 and GPT waveform output pins into high-impedance state. Triggers include comparator-detection of overcurrent, software command, or oscillation stoppage-bypassing CPU intervention. This sub-microsecond response, combined with IEC 60730-compliant IWDT and LVD, ensures fail-safe shutdown in the R5F562TAADFH#V1 without firmware dependency.

Is CAN interface supported on the R5F562TAADFH#V1, and what configuration options are available?

Yes, the R5F562TAADFH#V1 includes a CAN 2.0B-compliant module with 32 configurable mailboxes, supporting both standard and extended frame formats. It operates at up to 1 Mbps and integrates message filtering, automatic retransmission, and error confinement-without requiring external CAN transceivers. The CAN module is fully integrated into the RX62T Group's peripheral bus architecture, enabling deterministic interrupt latency and DMA-assisted data transfer-making it suitable for real-time distributed motor control networks in the R5F562TAADFH#V1.
