Atmel AVR ATTiny Family

Posted by ardnahc pada 15 Oktober, 2013

Atmel is a manufacturer of semiconductors, founded in 1984. One of its main products is microcontrollers. The smallest in their AVR family of microcontrollers are the ATtiny series (8-bit core and less features, less I/O pins, and less memory than other AVR series, all of them are available in through-hole package).

Key Features

  • Small — Atmel tinyAVR devices are designed specifically for applications where size and cost are critical. The smallest tinyAVR measures only 1.5mm x 1.4mm. You can employ the tinyAVR as a single-chip solution in small systems. Or use them to deliver glue logic and distributed intelligence in larger systems.
  • Capacitive Touch — Atmel QTouch® Library makes it simple to embed capacitive-touch button, slider, and wheel functionality into general-purpose Atmel AVR® microcontroller applications. The royalty-free QTouch Library provides several library files for each device and supports different numbers of touch channels, enabling both flexibility and efficiency in touch application.
  • Fast and code efficient — The AVR CPU gives the tinyAVR devices the same high performance as our larger AVR devices, and several times the processing power of any similarly-sized competitor. Flexible and versatile, they feature high code efficiency that lets them fit a broad range of applications.
  • High integration — Each pin has multiple uses as I/O, ADC, and PWM. Even the reset pin can be reconfigured as an I/O pin. tinyAVR features a Universal Serial Interface (USI) which can be used as SPI, UART or TWI.
  • 0.7V operation — Where most microcontrollers require 1.8V or more to operate, the tinyAVR with boost regulator boosts the voltage from a single AA or AAA battery into a stable 3V supply to power the entire application.
