AT75C221-DK is a development kit designed for evaluation of Atmel AT75C221 MCU. The AT75C221 MCU features a hardware-enabled real-time clock and WDT. The AT75C221-DK board provides easy access to several features of the Atmel MCU, including four general-purpose IO-pin, UART, I2C and SPI communication, an on-board thermometer, and several power supply options. With the on-board debugging capability via Atmel JTAG interface, users can quickly develop and test applications on the MCU.

Application Field

The AT75C221-DK is ideal for applications requiring real-time clock with WDT control, such as industrial and automotive control systems. It is suitable for development of a broad range of embedded applications that require low power solutions, I2C and SPI communications, and on-board thermometer for temperature monitoring and control. The AT75C221-DK development system can be used for individual development projects or for extensive product testing and prototyping.

Working Principle

The AT75C221 MCU on the AT75C221-DK board can be used for a variety of applications, from general purpose to low-power solutions. The AT75C221-DK board contains the AT75C221 MCU, four general-purpose IO pins, UART, I2C and SPI communication ports, and a on-board thermometer, and an on-board debug port. The four general-purpose IO pins can be used for controlling the on-board devices. The UART port provides a connection to an external device, optionally with flow control and/or handshaking. The I2C and SPI ports allow fast communication with external devices.

The on-board debug port can be used for programming, debugging and testing applications on the AT75C221 MCU. The debug port is connected to the on-board JTAG port, making it possible to attach an external debugger. The on-board thermometer can be used for temperature monitoring and control applications. It is connected to the MCU through the ADC, making it possible to read the temperature via the ADC interface.

In addition, users can take advantage of the on-board power supply to drive their application. The AT75C221-DK board can be powered by either an external power supply or through USB, making it possible to quickly develop applications without the need of external circuitry. Other features include an on-board reset button for quickly resetting the board, and several user programmable options, including bootloader, reset, watch- dog and serial I/O settings.

The AT75C221-DK board is sold with an accompanying development environment, which includes various software libraries and example programs to get developers up and running quickly. With the help of these libraries, developers can create programs to control their application more easily and effectively. The development environment also includes a set of hardware tools, which can help developers debug their programs more effectively.

Overall, the AT75C221-DK board is a great choice for developers who need an embedded MCU with real-time clock support, I2C and SPI communication, and on-board thermometer. It is an excellent tool for quickly developing and testing applications with the Atmel AT75C221 MCU.
