It supports IEC60730 functional safety compliance and targets real-time motor drive systems requiring high-resolution timing and analog signal conditioning.

For engineers reviewing the R5F566TEADFN#30 datasheet, R5F566TEADFN#30 pinout, R5F566TEADFN#30 application, or R5F566TEADFN#30 equivalent, key selection criteria include its 160 MHz GPTW timer with 195 ps HRPWM resolution, dual 12-bit ADC units with pseudo-differential PGA inputs, CAN 2.0B interface, USB 2.0 FS host/function capability, and support for –40°C to +105°C operation in industrial environments.

Technical Context

The R5F566TEADFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time insertion, 9-channel MTU3d for 3-phase complementary PWM, 4-channel HRPWM with 195 ps minimum timing resolution, and ELC-driven event chaining that allows PWM-triggered ADC sampling without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEADFN#30?

The R5F566TEADFN#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance under benchmark conditions. This reflects its RXv3 CPU core efficiency, on-chip cache behavior, and memory subsystem bandwidth. The R5F566TEADFN#30 delivers deterministic real-time response for motor control loops running at ≥20 kHz update rates without compromising floating-point computation throughput.

Does the R5F566TEADFN#30 support IEC60730 Class B functional safety certification?

Yes, the R5F566TEADFN#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), RAM test-assisting function via DOC, CRC calculator (CRCA), independent watchdog timer (IWDT), and register write protection. These are documented in the R01DS0315EJ0130 datasheet and enable systematic fault detection without runtime software overhead. The R5F566TEADFN#30 itself is not certified-but provides all required building blocks for end-equipment certification.

What analog peripherals are integrated into the R5F566TEADFN#30 for motor current sensing?

The R5F566TEADFN#30 integrates three 12-bit S12ADH ADC units (30 total channels), six analog comparators (CMPC), two 12-bit D/A converters, and a three-channel programmable gain amplifier (PGA) supporting pseudo-differential input. For motor current sensing, it enables simultaneous sampling across shunt resistors or current transformers with hardware-triggered synchronization via GPTW/MTU3d events-ensuring <1 µs inter-channel skew. The R5F566TEADFN#30's PGA allows direct amplification of mV-level signals before ADC conversion, eliminating external op-amps.

Can the R5F566TEADFN#30 generate 3-phase complementary PWM waveforms with programmable dead time?

Yes, the R5F566TEADFN#30 supports 3-phase complementary PWM in both MTU3d (2-channel mode) and GPTW (10-channel mode), with automatic dead-time insertion and non-overlapping waveform generation. Dead time is programmable per channel in nanosecond granularity, and HRPWM overlay adds 195 ps fine-tuning capability. Output disable is hardware-triggered via POE3B/POEG on comparator fault, overcurrent, or oscillation stop-ensuring safe shutdown within one system clock cycle. This makes the R5F566TEADFN#30 suitable for driving IGBT/SiC half-bridges in industrial inverters.

What is the package type and thermal rating of the R5F566TEADFN#30?

The R5F566TEADFN#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with 20 mm × 20 mm body and 0.5 mm pitch (PLQP0144KA-B). It is rated for operation from –40°C to +105°C (G-version), qualified per JEDEC JESD22-A108. The exposed pad enhances thermal dissipation in high-power motor control applications. This package supports standard lead-free reflow profiles and is compatible with automated optical inspection (AOI) and X-ray void detection for industrial manufacturing quality assurance.
