Embedded - Microprocessors

T2081NXN8T1B is a microcontroller developed by NXP Semiconductors for applications such as embedded systems, industrial controls and medical devices. It is a 32-bit ARM Cortex-M4 processor core with on-chip memory, non-volatile memory, USB and Ethernet controllers, and an analog-to-digital converter.

Application Field

The T2081NXN8T1B microcontroller can be used in a variety of applications. It is especially suited for industrial automation applications, as it has a "Real-Time Unit" that allows for high-speed operation with deterministic real-time interrupts and motor control. It is also well-suited for medical systems, as it provides accurate and low power data acquisition and control of medical sensors or actuators. The controller has built-in Ethernet connectivity, which makes it well-suited for industrial communication systems.

Working Principle

The T2081NXN8T1B uses a 32-bit ARM Cortex-M4 processor core as its main processing unit. The processor is divided into two cores, the Cortex-M4 core and the Real-Time Unit. The Real-Time Unit is responsible for the real-time operation and deterministic interrupts, allowing for high-speed operation and motor control. The Cortex-M4 core is responsible for running applications, such as controlling GPIO pins, Ethernet communications, and USB communication. All the on-chip peripherals, such as the analog-to-digital converter, are connected to the Cortex-M4 core.

The T2081NXN8T1B also has on-chip memory for storing code and data. The code is stored in the volatile memory, which is cleared when the power is turned off. The non-volatile memory is used for data storage and it remains valid even when the power is turned off. The controller also includes a bootloader, which allows for easy programming and updates to the application code.

The controller is programmed using NXP Semiconductor\'s Kinetis Design Studio. This integrated development environment (IDE) provides a complete set of tools for creating and debugging the application code. The IDE also supports a variety of debugging tools, such as code coverage and execution trace.

Conclusion

The T2081NXN8T1B microcontroller is a powerful and versatile device that can be used in a variety of industrial, medical and consumer applications. It is especially well-suited for industrial applications, as it has a Real-Time Unit that allows for deterministic real-time operation and motor control. The on-chip memory, Ethernet and USB controllers make it suitable for communication systems. Programming the controller is made easy with the Kinetis Design Studio IDE.
