Questions tagged [atmel]

Atmel is the creator of microcontrollers like the AVR line (ATmega and ATtiny) and SAM devices. Many Arduino microcontroller boards use Atmel's AVR line of devices.

Atmel was acquired by Microchip Technology Inc. (Nasdaq: MCHP) in 2016.

Popular for its 8- and 32-bit line of and microcontrollers, Atmel products are widely used by hobbyists and industry professionals alike. The AVR chips are the basis of the popular line of prototyping platform boards. Atmel/Microchip also offers a line of 32-bit ARM-based microcontrollers called "SMART Atmel microcontroller" or SAM. Some common Atmel/Microchip boards and platforms include the AVRISP-mkII, the STK500 and STK600, the AVR Dragon, and the SAM [E70/V71] Xplained.

The Atmel Studio IDE (and, in previous years, AVR Studio), is based on Microsoft's Visual Studio. It is a code development, upload, and debugging tool for AVR and SAM microcontrollers. Atmel Studio can be downloaded from the Microchip website.
