NUC120RE3DN

Microcontrollers Overview

The NUC120RE3DN is a 32-bit microcontroller from the NuMicro NUC120 USB Line series, featuring an ARM Cortex-M0 core operating at up to 50 MHz. It integrates 128 KB of Flash memory and 16 KB of SRAM within a 64-pin LQFP package. The device supports a supply voltage range of 2.5V to 5.5V and operates across a temperature range of -40°C to +85°C. Connectivity includes one USB 2.0 Full-speed Device interface alongside multiple serial communication peripherals.

Microcontrollers Feature Summary

• Communication systems

Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging material changes documented in Product Change Notices. Ensure the part number matches the exact suffix requirements for the 64-LQFP package variant.

Microcontrollers Selection Notes

Select this model when USB connectivity is required alongside substantial program memory. The 128 KB Flash and 16 KB SRAM configuration suits complex firmware applications. Verify pin compatibility with existing designs as the 64-pin LQFP footprint differs from other series variants.

Microcontrollers Part Context

This component belongs to the NuMicro NUC120 USB Line, distinct from the NUC100 Advanced Line by its inclusion of a USB device controller. It shares the same Cortex-M0 core architecture and peripheral set but targets applications requiring universal serial bus integration without external transceivers.
