Technical Context

The R5F566TAEGFP#10 implements the RXv3 CPU core with single-cycle instruction execution at up to 160 MHz and IEEE 754-compliant single-precision FPU. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated oscillator, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Motor control functionality is anchored by 10-channel 32-bit GPTW timers supporting single-/3-/5-phase complementary PWM with programmable dead time, 4-channel HRPWM with 195 ps timing resolution, and ELC-driven event chaining that enables autonomous peripheral coordination without CPU intervention during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAEGFP#10?

The R5F566TAEGFP#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and optional 8-KB ROM cache. The R5F566TAEGFP#10 maintains deterministic timing at full speed, making it suitable for real-time motor control loops where cycle-accurate execution is mandatory.

Does the R5F566TAEGFP#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TAEGFP#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), and register write protection. These are implemented in silicon and documented in the R01DS0315EJ0130 datasheet. The R5F566TAEGFP#10 enables certified implementations without external components, reducing validation effort for industrial and appliance safety certification.

What analog peripherals are integrated into the R5F566TAEGFP#10 for motor current sensing?

The R5F566TAEGFP#10 integrates three 12-bit ADC units (S12ADH) totaling 30 channels, six analog comparators (CMPC), two 12-bit DACs, and a programmable gain amplifier (PGA) with pseudo-differential input across six channels. Units 0 and 1 each include three sample-and-hold circuits, enabling simultaneous current sampling across multiple shunt resistors. The R5F566TAEGFP#10 supports direct connection of low-side shunt amplifiers, eliminating external signal conditioning in compact inverter designs.

Can the R5F566TAEGFP#10 generate 3-phase complementary PWM waveforms with automatic dead-time insertion?

Yes, the R5F566TAEGFP#10 supports 3-phase complementary PWM through its MTU3d module (9 channels) and GPTW timers (10 channels). MTU3d provides hardware dead-time insertion, non-overlapping waveform generation, and synchronous PWM updates - all configurable without CPU overhead. The R5F566TAEGFP#10 also includes POE3B circuitry to force PWM outputs into high-impedance state during fault conditions, ensuring safe inverter shutdown.

What package type and pin count does the R5F566TAEGFP#10 use?

The R5F566TAEGFP#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with PLQP0144KA-B designation: 20 × 20 mm body, 0.5 mm pitch, and exposed thermal pad. It provides 110 general-purpose I/O pins, including 4 with 5-V tolerance, 110 pull-up resistors, and 110 open-drain outputs. This package balances high I/O density with thermal performance for motor control applications operating up to +105°C.
