Renesas R5F566TAFDFL#10

Overview

R5F566TAFDFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter 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 timers - deployed in HVAC compressors, servo drives, and industrial PMSM/BLDC motor systems.

For engineers reviewing the R5F566TAFDFL#10 datasheet, R5F566TAFDFL#10 pinout, R5F566TAFDFL#10 application, or R5F566TAFDFL#10 equivalent, key selection criteria include its 10-channel 32-bit GPTW timer with 195 ps HRPWM resolution, dual 12-bit A/D converters supporting simultaneous sampling across 30 channels, CAN 2.0B compliance with 32 mailboxes, and IEC60730 safety support including CAC, CRCA, and RAM test-assisting DOC.

Technical Context

The R5F566TAFDFL#10 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111 instructions including DSP extensions. Its clock system integrates PLL, high-speed on-chip oscillator (16–20 MHz), and low-speed 240 kHz LOCO - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for deterministic timing of GPTW, MTU3, and HRPWM modules.

Motor control execution relies on tightly coupled peripherals: ELC enables interrupt-free inter-module triggering (e.g., GPTW overflow → S12ADH conversion start), POE3B/POEG provide hardware-level output disable during fault detection, and the 6-channel analog comparator (CMPC) with programmable gain amplifiers supports real-time current sensing and overcurrent protection without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAFDFL#10?

The R5F566TAFDFL#10 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 - validated per R01DS0315EJ0130 Rev.1.30. The R5F566TAFDFL#10 sustains this performance across its full industrial temperature range (–40°C to +105°C) with appropriate decoupling and thermal design.

Does the R5F566TAFDFL#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TAFDFL#10 includes dedicated hardware for IEC60730 Class B certification: clock accuracy measurement circuit (CAC), CRC calculator (CRCA), oscillation-stop detection, RAM test-assisting DOC, and register write protection. These features are documented in Section 1.1 and Chapter 27 of R01DS0315EJ0130 Rev.1.30 and require no external components to implement self-test routines for safety-critical motor control applications.

What PWM resolution does the R5F566TAFDFL#10 achieve, and how is it implemented?

The R5F566TAFDFL#10 achieves a minimum PWM timing resolution of 195 ps using its 4-channel High-Resolution PWM (HRPWM) circuit, which fine-tunes the edge timing of waveforms generated by GPTW0–GPTW3. This resolution is realized at 160 MHz system clock and is specified in Table 1.1 (Page 4) and Section 18.3.1 of R01DS0315EJ0130 Rev.1.30 - enabling sub-nanosecond gate drive alignment in SiC/GaN inverter designs.

How many A/D converter channels does the R5F566TAFDFL#10 support, and what sampling capability does it offer?

The R5F566TAFDFL#10 integrates three 12-bit S12ADH units totaling 30 input channels: Unit 0 (8 ch), Unit 1 (8 ch), Unit 2 (14 ch). It supports simultaneous sampling across all three units - critical for vector control - with minimum conversion time of 0.9 µs per channel at 60 MHz ADCLK. This capability is detailed in Section 19.1 and Table 1.1 (Page 9) of R01DS0315EJ0130 Rev.1.30.

What package type and pin count does the R5F566TAFDFL#10 use?

The R5F566TAFDFL#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0144KA-B: 20 × 20 mm body, 0.5 mm lead pitch, with exposed thermal pad. It provides 110 general-purpose I/O pins, including 4 with 5-V tolerance and 15 with large-current drive capability - as confirmed in Table 1.1 (Page 4) and Package Information section of R01DS0315EJ0130 Rev.1.30.
