Frequently asked questions

Is Atmel still in business?

Atmel (AVR ATmega/ATtiny, SAM Arm MCUs, AT24/AT25 EEPROM, CryptoAuthentication) was acquired by Microchip Technology in 2016.

Can I still buy Atmel parts?

Yes. PartnerSemi quotes Atmel part numbers, including obsolete and end-of-life parts and parts with old Atmel markings. Send the part number and quantity; we reply with price, lead time, date code and origin. We are an independent distributor, not an authorized Atmel or Microchip Technology distributor.
