NUC029NAN

Introduction

The NuMicro® NUC029 series represents a collection of microcontrollers designed by Nuvoton Technology for applications in industrial control systems. This series is noted for its enhanced robustness against electromagnetic disturbances, showcasing impressive immunity capabilities with ESD protection up to Human Body Model (HBM) 8 kV and Electrical Fast Transients (EFT) up to 4.4 kV. These microcontrollers are powered by an Arm® Cortex®-M0 core and provide a comprehensive set of features for a wide range of applications.

Function & Applications

The NuMicro® NUC029 series is particularly suited for use in environments requiring stable operation under varying electrical disturbances. Their robust protection features and extensive peripheral support make them an excellent fit for:

- Industrial Controls
- Smart Home Systems
- Brushless DC (BLDC) Motor Control
- Consumer Electronics

Performance Parameters

The NUC029 series operates within a voltage range of 2.5V to 5.5V and can withstand temperatures from -40 ℃ to +105 ℃. The microcontrollers can achieve an operating frequency of 24 MHz to 72 MHz and incorporate various amounts of Flash and SRAM depending on the specific model. With up to 256 KB Flash and up to 20 KB SRAM, they are well-equipped for a multitude of tasks. ADC resolution is consistent across the range with a 12-bit 1 Msps ADC providing precision and speed in analog to digital conversion.

Package Types, Interface & Pin Configuration

NUC029NAN supports the package type of QFN48. The QFN48 package measures 7x7mm, conveniently compact for space-conscious designs. Interfaces include several UART ports, multiple I²C and SPI buses, PWM channels, and more. Notably, specific versions include a crystal-less USB 2.0 full-speed interface, adding USB connectivity without the need for external crystal components, saving total cost and space.

Reliability & Lifespan

The NUC029 series is built for endurance, with design considerations that ensure stable operation over long periods. The ability to function in harsh temperature ranges and withstanding high levels of ESD attests to their reliability and the overall robustness is indicative of a long lifespan under normal operating conditions.

Standards & Certifications

Nuvoton's microcontrollers adhere to global industry standards for electronic components. While details on specific certifications for the NUC029 series were not provided, buyers can generally expect compliance with standard certifications like RoHS, REACH, and possibly ISO standards related to quality management and environmental considerations.
