Part	Spec A	Spec B	Spec C	Spec D	Description

Atmel, acquired by Microchip Technology in 2016 for $3.56 billion, revolutionized the microcontroller industry with the AVR family of 8-bit RISC microcontrollers developed since 1996. AVR was one of the first MCU families to use on-chip flash memory for program storage, enabling easier development and in-system programming that made it a favorite among hobbyists and professionals alike.

The Atmel product portfolio encompasses 8-bit AVR microcontrollers, 32-bit AVR and ARM-based processors with Cortex-M and Cortex-A cores, automotive-grade MCUs, radio-frequency devices including Wi-Fi, EEPROM and flash memory, security chips, and touch sensors and controllers. AVR microcontrollers gained widespread popularity through their inclusion in Arduino development boards, making them essential components in the maker movement.
