Renesas R5F562TAADFF#H3

Overview

R5F562TAADFF#H3 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 (4 channels each, with sample-and-hold, programmable gain amplifiers, and window comparators), one 10-bit ADC (12 channels), 8×16-bit MTU3 timers with three-phase complementary PWM, 4×16-bit GPT timers, CAN interface, and 256 KB flash/16 KB SRAM/32 KB data flash - all operating across –40°C to +85°C.

For engineers reviewing the R5F562TAADFF#H3 datasheet, R5F562TAADFF#H3 pinout, R5F562TAADFF#H3 application, or R5F562TAADFF#H3 equivalent, key selection criteria include its 100-MHz PWM timing resolution (312 ps delay control on GPT), IEC 60730-compliant self-diagnostic A/D and CRC units, and support for simultaneous 7-channel sampling across three ADC units.

Technical Context

The R5F562TAADFF#H3 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 independent PCLK up to 50 MHz, enabling synchronized high-speed CPU and peripheral operation.

It features dedicated hardware acceleration for motor control: MTU3 provides two three-phase complementary PWM output channels with automatic dead-time insertion and phase-counting mode; GPTa enables precise PWM edge delay (±312 ps at 100 MHz) and three-phase waveform generation; POE3 supports fast hardware shutdown of PWM outputs via comparator or fault detection.

FAQ

What is the maximum operating frequency and CPU performance of the R5F562TAADFF#H3?

The R5F562TAADFF#H3 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance. It features a 32-bit RX CPU core with single-precision IEEE-754 floating-point unit, 64-bit accumulator for 32×32-bit operations, and hardware divider - enabling efficient execution of motor control algorithms such as field-oriented control and sensorless estimation without external coprocessors.

Does the R5F562TAADFF#H3 support IEC 60730 Class B functional safety requirements?

Yes, the R5F562TAADFF#H3 includes multiple hardware features required for IEC 60730 Class B compliance: independent watchdog timer (IWDT) with dedicated LOCO clock, CRC calculation unit for memory and data integrity checking, self-diagnostic A/D converter (generating internal reference voltages), oscillation stop detection, and PORT register read-back capability for output pin verification - all documented in Renesas' functional safety manual R01US0078EJ0200.

What ADC resources does the R5F562TAADFF#H3 provide for motor current sensing?

The R5F562TAADFF#H3 provides three A/D converter units: two 12-bit S12ADA units (4 channels each, with sample-and-hold, programmable gain amplifiers, and window comparators) and one 10-bit ADA unit (12 channels). All three units support simultaneous 7-channel sampling - allowing concurrent acquisition of U/V/W phase currents and DC bus voltage within a single conversion trigger, essential for accurate field-oriented control loops.

How does the R5F562TAADFF#H3 implement hardware-based fault protection for inverter stages?

The R5F562TAADFF#H3 uses Port Output Enable 3 (POE3) with five dedicated inputs (POE0/4/8/10/11) to initiate immediate hardware shutdown of MTU3 and GPT PWM outputs. When triggered by comparator output, short-circuit detection, or software, POE3 forces selected PWM pins into high-impedance state in under 100 ns - bypassing CPU latency and preventing shoot-through in IGBT or MOSFET half-bridges during overcurrent events.

What is the package type and pin count of the R5F562TAADFF#H3?

The R5F562TAADFF#H3 uses the PLQP0080JA-A package: an 80-pin LQFP with 14×14 mm body size and 0.65 mm pin pitch. It provides 61 general-purpose I/O pins and 21 input-only pins, including dedicated MTU3/GPT PWM outputs, CAN transceiver interface, SCI, I²C, RSPI, and LIN signals - optimized for compact inverter control board layouts.
