Product details
Overview
R5F566NDHGBD#20 from Renesas is a 32-bit RXv3 microcontroller optimized for industrial motor control, featuring a 160 MHz CPU core, 1 MB on-chip code flash, 128 KB SRAM, 32 KB data flash with 100,000 write cycles, and integrated high-resolution PWM (195 ps minimum resolution) for precise inverter gate timing. It supports IEC60730 safety compliance and operates across –40°C to +105°C.
For engineers reviewing the R5F566NDHGBD#20 datasheet, R5F566NDHGBD#20 pinout, R5F566NDHGBD#20 application, or R5F566NDHGBD#20 equivalent, key selection criteria include its 144-pin LFQFP package, dual 12-bit A/D converters with simultaneous sampling across 30 channels, 10-channel 32-bit GPTW timer with 3-phase complementary PWM, CAN 2.0B interface, and TSIP-Lite encryption engine supporting AES-128/256.
Technical Context
The R5F566NDHGBD#20 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, executing at up to 160 MHz with 928 CoreMark performance. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz), enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).
Motor control functionality is anchored by three synchronized timer subsystems: 10-channel 32-bit GPTW with dead-time generation and phase-counting, 9-channel 16-bit MTU3d supporting 3-phase complementary PWM, and 4-channel HRPWM delivering 195 ps timing resolution for gate drive edge alignment - all coordinated via the Event Link Controller (ELC) to minimize CPU intervention during real-time waveform updates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566NDDGBD#20 | Same RX66T Group, identical 144-pin LFQFP package and 160 MHz core, but with 512 KB code flash and 64 KB SRAM instead of 1 MB/128 KB | Targeted at cost-sensitive inverters with smaller firmware footprints and reduced real-time buffer requirements | Select when application firmware size remains under 400 KB and SRAM usage stays below 50 KB - reduces bill-of-materials cost by ~14% |
| R5F566NEHGBD#20 | Same package and memory configuration, but adds USB HS (480 Mbps) and Ethernet MAC; lacks TSIP-Lite encryption engine | Suitable for gateway-class motor controllers requiring network connectivity but not cryptographic firmware protection | Choose when integrating EtherCAT or PROFINET slave stacks; omit if AES-based firmware signing or secure boot is mandatory |
