Evaluation and Demonstration Boards and Kits fulfill a variety of essential roles in product development and engineering activities. Such boards help facilitate the rapid prototyping and testing of various electronic products, such as microcontrollers, sensors, and ASICs, and are thus indispensable for product development. CDBWM8983-M-1 is one such evaluation board designed to mainly evaluate and demonstrate the capabilities of NXP’s LPC800-series Cortex-M0+ microcontrollers. This paper will discuss the various application fields and working principles of the CDBWM8983-M-1 evaluation board.

CDBWM8983-M-1 is equipped with several useful features, including an onboard LPC801, 200 MHz, 32-bit ARM Cortex-M0+, for executing code, as well as LCD and seven segment displays. The board also consists of two USB interfaces, an Ethernet port, SD/MMC card interface, I2C interface, SPI interface and various inputs/outputs. Additionally, CDBWM8983-M-1 has in-system programming capabilities via a debug interface, allowing users to execute firmware as well as observe or modify the device data while it is running. This evaluation board also supports debugging of the code using the embedded ROM monitor.

The main application fields of the CDBWM8983-M-1 evaluation board can be broadly classified into three categories. The first category involves development and evaluation of embedded applications related to automation, instrument control, medical, automotive, and consumer electronics. These applications require the microcontrollers to execute various code, for which the board is well-equipped. The second and third categories focus on the development of products related to industrial control and audio/video applications respectively. In these applications, the microcontrollers are responsible for providing efficient data transfer and rich multimedia features, for which the board is well-suited due to its I2C, SPI and USB interfaces.

Regarding the working principle of the CDBWM8983-M-1, the onboard LPC801, 200 MHz, 32 bit ARM Cortex-M0+ microcontroller is used to manage and execute code. This microcontroller is responsible for running the code, setting the I/O addresses for digital input/output pins and configuring the power management of the board. Additionally, the microcontroller can also manage the internal clocks, oscillators and interrupt controllers for better system control. All these tasks are managed by the on-board LPC801 for which the onboard debugging capabilities provided by the board can be used.

Apart from powering the board, connecting the sensors, instruments, and communication peripherals such as Ethernet, USB, and Bluetooth, also involve setting up the actual application. To that end, all the necessary library files and configurations can be provided from the board’s support page. Further, a few special types of applications require special parts or initial programming which can be achieved via the debug interface. After this, the board is ready to execute the code and begin development.

To summarize, the CDBWM8983-M-1 evaluation board can be utilized in embedded applications related to automation, instrument control, medical, automotive, consumer electronics, industrial control, and audio/video applications. Its onboard LPC801, 200 MHz, 32 bit ARM Cortex-M0+, microcontroller is used to manage and execute code. Furthermore, the board supports on-board debugging capabilities for developing and debugging code. In addition, the board also supports connection of various sensors, instruments, and communications peripherals such as Ethernet, USB, and Bluetooth.
