Renesas R5F566TEFDFL#50

Overview

R5F566TEFDFL#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial real-time applications, operating at up to 160 MHz with 928 CoreMark performance, 1 MB on-chip code flash, 128 KB SRAM (no wait states), and integrated 3-phase/5-phase complementary PWM generation. It features 110 GPIO pins, 32 KB data flash (100,000 write cycles), and hardware encryption (AES-128/256) for IEC 60730-compliant inverters and servo drives.

For engineers reviewing the R5F566TEFDFL#50 datasheet, R5F566TEFDFL#50 pinout, R5F566TEFDFL#50 application, or R5F566TEFDFL#50 equivalent, this MCU delivers deterministic 195-ps high-resolution PWM timing, simultaneous 3-unit 12-bit ADC sampling, dual 12-bit DACs for comparator reference, and CAN 2.0B + USB 2.0 FS host/function support - all in a 144-pin LFQFP package rated for –40°C to +105°C operation.

Technical Context

The R5F566TEFDFL#50 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 dedicated IWDT oscillator, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for precise timer and ADC synchronization.

Real-time control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with dead-time insertion and ELC-triggered event chaining, 9-channel MTU3d for 3-phase inverter gate drive, 4-channel HRPWM with 195-ps resolution, and S12ADH ADC units supporting pseudo-differential PGA inputs across 30 total channels.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEFDFL#50?

The R5F566TEFDFL#50 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem - enabling deterministic execution of complex motor control algorithms in real time.

Does the R5F566TEFDFL#50 support simultaneous sampling across all 30 ADC channels?

No - the R5F566TEFDFL#50 supports simultaneous sampling only across the three S12ADH units (up to 7 channels per unit in group scan mode), totaling up to 21 channels sampled at once. All 30 channels are accessible but require sequential or staggered triggering; true 30-channel simultaneous capture is not supported.

What package type and dimensions does the R5F566TEFDFL#50 use?

The R5F566TEFDFL#50 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package measuring 20 mm × 20 mm with 0.5 mm pitch, exposed thermal pad, and RoHS compliance. It is distinct from smaller variants like the 100-pin or 80-pin LFQFP options in the RX66T family.

Can the R5F566TEFDFL#50 operate with a 5-V supply, and what are the voltage domain constraints?

Yes - the R5F566TEFDFL#50 supports a 2.7–5.5 V VCC supply and is 5-V tolerant on selected GPIO pins. However, analog domains require AVCC0/1/2 ≥ VCC (3.0–5.5 V), and USB operation mandates VCC_USB = 3.0–3.6 V (separate from main VCC when active). Violating these domain relationships risks ADC accuracy or USB PHY failure.

Is the R5F566TEFDFL#50 certified for IEC 60730 Class B compliance?

The R5F566TEFDFL#50 includes hardware features required for IEC 60730 Class B self-test: oscillation-stop detection, CRC calculator (CRCA), RAM test assist (DOC), register write protection, and independent watchdog timer (IWDT). Full certification requires system-level implementation - Renesas provides application notes and safety manuals to guide qualification.
