The NUC120LD2BN can also be used in security and surveillance systems, as it can interface with cameras, motion sensors and other peripheral devices to detect and monitor for potential threats. Its low-power consumption adds to its appeal for these applications.

Working Principle

The NUC120LD2BN is based on the Cortex-M0 architecture by ARM. It is a 32-bit embedded processor and offers various features such as low-power operation, rich peripheral set and integrated CAN, USB FS and I2C bus interfaces. The processor contains four built-in multifunction timers, PWM and a 48MHz system clock.

The Flash-Memory System of the NUC120LD2BN is 4MB. The Flash memory contains a boot loader, ISR vector table as well as pre-defined and user-defined configurations. It also contains an on-chip debugger (OCD) for application debugging on the target hardware.

The NUC120LD2BN also has 128KB of SRAM memory, which contains all application variables, stack and heap memory. When power loss occurs, the SRAM is responsible for restoring the contents of the Flash memory and restoring the system to its previous state.

The processor uses a power management system to conserve energy when the system is idle. The system has four power modes: Active, Idle, Power Down and Off. The system can switch between power modes, depending on the application’s requirements. In all modes, the processor consumes very little power.

The NUC120LD2BN also has an extensive range of internal and external peripherals. These include a CAN module, UART, I2C, USB, A/D converter as well as a range of embedded security features. All of these features make it an ideal option for embedded applications.

The NUC120LD2BN is designed to be an easy and effective processor to use. It has many development tools, such as Keil MDK, IAR Embedded Workbench and GCC, to help simplify the development process. These tools come bundled with the processor, enabling any user to develop applications quickly and easily.

The NUC120LD2BN is a powerful embedded microcontroller and is an ideal choice for applications requiring low-power operation and a high-speed device interface. Applications such as robotics, medical equipment, surveillance systems and more would benefit from the processor’s low-power operation and peripheral support.
