Renesas R5F566NNDGBD#20

Overview

R5F566NNDGBD#20 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 high-resolution PWM (195 ps minimum resolution) for precision inverter gate driving. It integrates dual 12-bit A/D converters (30-channel total), 6-channel analog comparators, 2-channel 12-bit D/A, CAN 2.0B, full-speed USB 2.0 host/function/OTG, and TSIP-Lite encryption - deployed in industrial servo drives and HVAC compressor controllers.

For engineers reviewing the R5F566NNDGBD#20 datasheet, R5F566NNDGBD#20 pinout, R5F566NNDGBD#20 application, or R5F566NNDGBD#20 equivalent, key selection considerations include its 144-pin LFQFP package with 110 GPIOs (4 × 5-V tolerant), 3-phase/5-phase complementary PWM capability, IEC60730 safety support (oscillation detection, RAM test assist, CRC, register write protection), and dual-clock domain operation (ICLK @ 160 MHz, PCLKA @ 120 MHz, PCLKC @ 160 MHz).

Technical Context

The R5F566NNDGBD#20 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 111-instruction set including DSP extensions. Its clock architecture separates system (ICLK), peripheral (PCLKA–PCLKD), and reference (PCLKC for GPTW/HRPWM) domains to enable concurrent high-speed timing control and data processing.

Real-time motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers synchronized to PCLKC @ 160 MHz, 4-channel HRPWM with sub-200 ps edge placement, ELC-driven event chaining (188 internal signals), and simultaneous sampling across three 12-bit S12ADH units - all coordinated without CPU intervention during deep software standby.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566NNDGBD#20?

The R5F566NNDGBD#20 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, and IEEE 754-compliant FPU - validated under conditions specified in Renesas document R01DS0315EJ0130. The R5F566NNDGBD#20 delivers deterministic real-time response for motor control loops requiring sub-microsecond latency.

Does the R5F566NNDGBD#20 support IEC60730 Class B compliance out of the box?

Yes, the R5F566NNDGBD#20 includes dedicated hardware features for IEC60730 Class B compliance: clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, main clock oscillation stop detection, RAM test-assisting function (via DOC), CRC calculator (CRCA), and register write protection. These are documented in the R01DS0315EJ0130 datasheet and enable certified safety routines without external components - critical for R5F566NNDGBD#20 deployment in household appliances and industrial drives.

What is the resolution and timing capability of the HRPWM in the R5F566NNDGBD#20?

The R5F566NNDGBD#20 provides 4-channel High-Resolution PWM (HRPWM) capable of controlling rising/falling edges of GPTW0–GPTW3 outputs with a minimum resolution of 195 ps when operating at 160 MHz. This enables precise dead-time tuning below 1 ns - essential for minimizing shoot-through in SiC and GaN-based inverter stages. The HRPWM functionality is fully integrated and requires no external timing ICs, directly enhancing R5F566NNDGBD#20's suitability for next-generation power electronics.

How many A/D converter channels does the R5F566NNDGBD#20 support, and what is its sampling architecture?

The R5F566NNDGBD#20 integrates three 12-bit S12ADH units totaling 30 analog input channels: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). It supports simultaneous sampling across all three units - enabling synchronized current/voltage acquisition for vector control algorithms. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, and programmable gain amplifiers (6 channels) support pseudo-differential inputs - key capabilities confirmed in R01DS0315EJ0130 for R5F566NNDGBD#20.

What package type and thermal characteristics apply to the R5F566NNDGBD#20?

The R5F566NNDGBD#20 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for operation from –40°C to +105°C (G-version), with thermal resistance θJA ≈ 32°C/W (typical, JEDEC JESD51-7). This package supports high-power motor control applications where thermal dissipation and board-level reliability under industrial temperature cycling are critical - consistent with R5F566NNDGBD#20's target use cases.
