NUC120RD2DN

The NUC120RD2DN has a wide range of applications and uses in embedded microcontrollers as well as other embedded system designs. The device has several features that make it ideal for applications such as motor control, automotive, consumer, industrial, and medical. It has an 8-bit high-speed CPU with flash memory, an enhanced UART, I2C bus and an internal 10-bit AD and 2x 16-bit synchronous timer. The CPU, flash memory and enhanced UART are all integrated on one chip, making the NUC120RD2DN an efficient, low-cost solution for embedded applications.

Power Saving

The NUC120RD2DN has several power saving methods, making it suitable for battery operated systems. The chip\'s power saving mode is enabled when the CPU core is not actively being used. This mode reduces the current consumption of the MCU, saving energy for the system. The low power sleep and suspend modes, enabled through special commands, also provide a more power efficient operation than a full-speed run. The NUC120RD2DN also has an Auto Power Down (APD) mode which enables power to be saved while a device is not actively in use.

Clock System

The NUC120RD2DN has an independent clock system which can be configured to any frequency between 1MHz and 48MHz. This allows the device to operate in high-speed mode while also providing low-power operation by reducing the clock frequency. The clock system also provides a wide range of clock sources including a 12MHz high-speed oscillator, 4MHz RC oscillator, PLL, and an external clock source. This provides flexibility in applications requiring high-speed and low power operation.

Memory System

The NUC120RD2DN includes an 8Kbyte flash memory for program code and data storage. The device also includes a 8Kbyte Data RAM for general purpose applications, and 2Kbyte of SRAM for data storage. The SRAM can be used for caching frequently used data, as well as storing data from the external memory or from fast analog-to-digital coverters. The memory can be further expanded with the addition of an external memory, such as an SRAM or Flash.

Peripheral Interfaces

The NUC120RD2DN has a wide range of peripheral interfaces that provide flexibility in system design. These include an enhanced UART for debug support and an I2C bus for program and data transfer between devices. The device has an enhanced integrated analog-to-digital converter (ADC) which supports up to 8 channels with true differential inputs and 8 bit resolution. Additionally, the NUC120RD2DN supports up to 2x 16-bit synchronous timers which can be used for applications such as pulse width modulation (PWM), pulse position modulation (PPM), and quadrature encoder inputs. The NUC120RD2DN also features a digital temperature sensor which can be used to measure the temperature of the device.

Development Environment

The NUC120RD2DN comes with a software development environment that provides all the necessary tools for developing embedded applications. The development suite includes the Keil C Compiler, Integrated Development Environment (IDE), library of source code and other support tools, and a serial-to-USB converter for debugging and programming the device. The development environment is easy to install and use, and provides a powerful platform for creating and testing applications for the NUC120RD2DN.

Conclusion

The NUC120RD2DN is a compact, low-cost microcontroller, suitable for a wide range of embedded system designs. The chip includes a 8-bit high-speed CPU with flash memory, an enhanced UART, I2C bus and an internal 10-bit AD and 2x 16-bit synchronous timer. The device also features several power saving methods, an independent clock system and a wide range of peripheral interfaces. The NUC120RD2DN is equipped with an easy to use software development environment that provides all the necessary tools for developing and testing applications.
