The ATSTK200 is a versatile peripheral evaluation board for Microcontroller and Digital Signal Processor applications. With its dual-core architecture and peripheral-rich design, the ATSTK200 offers an ideal platform for evaluating, developing, and testing embedded applications. This article will explore the features of the ATSTK200, discuss its application fields, and explain its working principles.

Features of the ATSTK200

The ATSTK200 is a powerful and highly integrated peripheral evaluation board. It contains an 8-bit microcontroller (MCU) and a digital signal processor (DSP) core, both of which are designed to meet the requirements of embedded application development. The MCU includes 64K bytes of ROM and 1K of RAM, along with a variety of peripherals, such as a 10-bit A/D converter, serial port, I2C and SPI peripherals, and a watchdog timer. The 8-bit MCU is compatible with a wide range of programming environments, such as C, assembler, basic, and other compilers. The DSP core has 16K bytes of ROM and 1K of RAM, along with two programmable timers, three analog comparators, and a serial communications interface.

In addition to the core MCU and DSP, the ATSTK200 also includes an integrated LCD driver to support a variety of LCD display technologies. It also contains support for external SDRAM, so that large amounts of data can be readily stored and read. The onboard USB 2.0 interface enables fast transfer of data from the evaluation board to a PC. This port is also suitable for programming the board. And to further facilitate development, the evaluation board includes a resistor network, on-board debugging interface, and serial-to-USB converter.

Application Fields of ATSTK200

The ATSTK200 evaluation board is an ideal platform for a wide range of embedded applications. The dual-core architecture of the board provides designers with the flexibility to mix and match processing power as needed in their application. This makes the evaluation board suitable for use in hand-held devices, automated test and measurement systems, remote monitoring systems, medical developments, and robot control systems. In addition, the board is also ideal for developing industrial control applications that require both high-speed processing and analogue signal processing.

Working Principle of ATSTK200

The working principle of the ATSTK200 is based on the UART communication protocol. The UART protocol is an asynchronous serial communication system used to transfer data between two devices. In the ATSTK200, the MCU is used as the master device, while the DSP serves as the slave device. The MCU initializes and sends a clock signal to the DSP, which is then used to transfer data between the two devices. The UART protocol is designed to detect any errors in the data transmission, such as dropped clock signals, and resend the data to ensure correctness.

The ATSTK200 can also be used to develop and debug a variety of embedded applications. This is enabled by the board’s onboard debugging interface, which allows developers to connect the board to a PC. The debugging interface allows developers to write and view code, set breakpoints, monitor variables, and use various development tools. This helps developers quickly develop and test their applications, allowing them to develop faster and with fewer errors.

Conclusion

The ATSTK200 evaluation board is a powerful and flexible platform for developing and testing embedded applications, featuring two processor cores and a rich array of configurable peripherals. Its application fields range from hand-held devices to automated test and measurement systems. Moreover, its working principle is based on the UART communication protocol, and its onboard debugging interface allows developers to quickly develop and debug embedded applications. Therefore, the ATSTK200 provides an ideal platform for evaluating, developing, and testing embedded applications.
