AT90USB162-16AU is a general purpose, small-sized microcontroller (MCU) belonging to the AVR family from Atmel Corporation. These MCUs are built on a high-speed and high-performance, 8-bit RISC architecture that offers superior processing power, rich instruction set and large on-chip SRAM. They feature 16 KB Flash memory, 1 KB EEPROM and 512 Bytes of Static RAM, along with all the necessary peripherals needed to speed up the development of various applications.

The AT90USB162-16AU is primarily designed for embedded systems, industrial automation, home automation, appliances, and other applications involved with the control of a device or a system. It is particularly useful in applications where a small size, low power consumption and extreme low cost are the crucial points. It provides powerful instruction set, fast processing speed, and low power consumption, making it ideal for embedded applications.

The AT90USB162-16AU is based around a single core 8-bit RISC CPU, with all the necessary peripheral functions built into it. The microcontroller includes on-chip peripheral functions like UART, PWM, timers, I2C, SPI, and watchdog timer, along with the necessary input/output pins and program memory. The device is capable of operating up to 20Mhz.

The working principle of AT90USB162-16AU can be described as follows. It contains both fixed-length and variable-length instructions which are configured in memory. On each clock cycle, the instruction is read from the memory and is executed by the CPU. The instruction is then decoded and the corresponding action is performed. It also consist of an ALU (arithmetic logic unit) and an internal register set to manipulate data. The ALU performs arithmetic operations on the data such as addition, subtraction and comparison. It also performs logic operations such as OR, AND, XOR, NOT etc. The internal register set used to store the result of the instruction. The controller also contains a dedicated Debug Interface which provides communication link between host computer and the unit.

The AT90USB162-16AU is a versatile and low-cost solution for embedded applications. It provides power efficient and reliable operation along with a feature rich set of peripherals and a wide range of package options. It offers flexibility and ease of development with the aid of integrated bootloader. The controller is well suited for low-power applications, consuming only 4-mA/MHz typical active power at 16MHz.

In conclusion, the AT90USB162-16AU is a reliable and efficient microcontroller solution from Atmel Corporation. It provides a comprehensive feature set and ample performance for embedded applications at a cost effective price. Its low-power consumption ensures reliable operation for longer periods of time. It is an ideal solution for embedded applications where size, power consumption and cost are the primary requirements.
