The Atmel ATtiny104 Xplained Nano was specifically developed to accelerate the design process and support the Atmel ATtiny102 8-bit and ATtiny104 AVR microcontrollers. Part of Atmel's new Tiny AVR portfolio, these devices can run at up to 12 MIPS at 12 MHz and feature 1 KB of Flash, 32 bytes of SRAM, and a Universal Synchronous/Asynchronous Transmitter/Receiver (USART). The ATtiny104 Xplained Nano board provides a user button and LED, as well as access to all input/output (I/O) pins and other microcontroller features for easier evaluation. Additionally, the board has an embedded Atmel Mini Embedded Debugger (mEBDG), which is essentially a USB device consisting of two interfaces: a debugger and a virtual COM port. The mEBDG features an auto-ID for board identification in Atmel Studio, a green status LED on the board, and programming capabilities.
        
Using the ATtiny 104 USART interface, the Xplained Nano board can also communicate with a serial terminal via USB for debugging and verification, and can remain connected to the program terminal even during chip reprogramming. The onboard programmer can be completely disconnected from the host microcontroller or used to program any other microcontroller with the Atmel Tiny Programming Interface (TPI).
        
The ATtiny104 Xplained Nano is supported by the Atmel development ecosystem, including Atmel Studio 7, an integrated development environment (IDE) that provides designers with a transparent and user-friendly environment for coding, building, simulating, programming, and debugging applications for Atmel microcontrollers. The ATtiny104 Xplained Nano operates on a 5V supply voltage and is ideal for prototyping a variety of small applications, including logic replacement and cost-optimized applications in the industrial automation, consumer, and home markets.
