Embedded systems are becoming an integral part of various types of industry and consumer applications. Going beyond traditional consumer applications such as digital cameras, digital video recorders and mobile phones, embedded systems powered by microcontrollers are now being used in more complex industrial applications such as factory automation, robotics, and medical instrumentation, where reliability, accuracy and performance are all critical factors. The ATxmega16E5-MU is one of the latest microcontroller products from Microchip designed to address the requirements of embedded applications.

The ATxmega16E5-MU is an 8-bit low-power Microcontroller, designed for use in medical, industrial and consumer applications. It offers superior performance over regular 8-bit microcontrollers as it operates at 80MHz, has 256K bytes of flash program memory and 32K bytes of SRAM data memory. The reduced power consumption of the ATxmega16E5-MU is an added advantage for battery operated applications. The on-chip Low Voltage In-System Programming (LVP) technology allows the ATxmega16E5-MU to be programmed and updated in-system over the Serial Programming Interface (SPI).

The ATxmega16E5-MU features digital pulse width modulation (PWM) for high-speed pulse-width modulation (PWM) up to 32 channels. The PWM module in the ATxmega16E5-MU is used for controlling analog devices, like servo motors, speed control of motors, lighting dimmers and motor speed control. It also has 3-2-phase clock oscillators, 8-channel hardware-based interrupt capability and an Analog-to-Digital Converter (ADC) with 16-bit resolution. It also has 4 communications peripherals like USART, SPI, I2C and CAN.

The primary application area for the ATxmega16E5-MU is medical applications. It is used in Wearable and Implantable medical devices such as heart rate monitors, insulin pumps, drug delivery systems, spectrometers and other instrumentation devices. It is also widely used in factory automation and control systems, safety and security systems, targeted advertising devices and consumer appliances. Besides, the ATxmega16E5-MU can also be used in robotics and educational applications.

The working principle of the ATxmega16E5-MU is based on a von Neumann Architecture where instructions and data are stored in and retrieved from a common memory. The instructions are executed in a sequential manner. The ATxmega16E5-MU uses a Harvard architecture, where instructions and data are stored in separate memories. This allows for faster instruction fetch and execution as instructions and data are not competing for access to a single memory. The processor core of the ATxmega16E5-MU is the XMEGA AVR Core which is based on the 8-bit RISC processor designed by Microchip. The XMEGA AVR Core supports 8-bit and 16-bit data bus operations, pipelined instruction architecture, and hardware inter-instruction pipeline. It also supports Wake-up on Pin Change, Brown-out Detection and Clock Select (CSEL) feature to select the clock source.

The ATxmega16E5-MU consists of a peripheral set of modules like voltage reference, modules for timer, digital I/O, analog-to-digital converter, pulse width modulation and USART. The USART of the ATxmega16E5-MU can be used for wireless communication, data buffering and low-level communication protocols. The pulse width modulation feature of the ATxmega16E5-MU can be used to generate triangular, saw-tooth, square and arbitrary waveforms. The PWM can be used to control servo motors, motor speed, lighting control and motor speed control.

In summary, the ATxmega16E5-MU microcontroller is a powerful and energy efficient 8-bit device for embedded applications. It is used in medical, industrial and consumer applications. The onboard features of the ATxmega16E5-MU, such as its PWM, USART and Low Voltage In-System Programming (LVP) capability, make it an ideal choice for a variety of applications. The XMEGA AVR Core and separate instruction and data memories make the ATxmega16E5-MU an energy efficient and reliable processor for embedded applications.
