Product details
Overview
R5F566NDHGLK#20 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 160 MHz with 1 MB on-chip code flash, 128 KB SRAM, 32 KB data flash, integrated 12-bit A/D converter (30-channel), 4-channel high-resolution PWM (195 ps min. resolution), and CAN 2.0B interface compliant with ISO 11898-1.
For engineers reviewing the R5F566NDHGLK#20 datasheet, R5F566NDHGLK#20 pinout, R5F566NDHGLK#20 application, or R5F566NDHGLK#20 equivalent, this MCU delivers deterministic real-time motor control via 10-channel 32-bit GPTW timers, 3-phase complementary PWM with automatic dead-time insertion, hardware-accelerated encryption (AES-128/256), and IEC 60730 safety support including oscillation-stop detection and RAM self-test.
Technical Context
The R5F566NDHGLK#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 system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent PCLKA/PCLKB/PCLKC/PCLKD domain division enabling concurrent 160 MHz CPU operation and 120 MHz peripheral timing.
Motor control is enabled by tightly coupled peripherals: 32-bit GPTW timers synchronized to PCLKC for precise PWM edge placement, MTU3d units supporting 3-phase inverter gate drive with phase-counting and dead-time compensation, ELC for interrupt-free inter-module event chaining, and S12ADH with simultaneous sampling across three 12-bit A/D units for current/voltage feedback acquisition.
