Adesto to Expand DataFlash® and BIOS Flash Product Offerings

Sunnyvale, California, October 1st, 2012 /BUSINESS WIRE/ – Adesto Technologies, a
leading developer of next-generation non-volatile memory, has acquired Atmel’s Serial
Flash product families, including the company’s AT45xxx “DataFlash®” and AT25xxx
“BIOS Flash”product lines and associated patents. The acquisition also includes IP
licensing to cover support of the products and future product development.

Adesto® intends to expand the Atmel product line offerings to serve the future
requirements of existing customers while maintaining the same quality standards. With
the acquisition, Adesto increases its non-volatile memory technology portfolio. The
newly acquired products complement Adesto’s line of Conductive Bridging RAM
(CBRAM®) devices for embedded applications, which began shipping earlier this year.
Second generation CBRAM devices are planned to ship in 2013.

“Adesto’s acquisition of Atmel’s DataFlash® and BIOS Flash products marks a major
turning point in the company’s plan to be a full line supplier of premium, non-volatile
memory solutions,” said Narbeh Derhacobian, CEO of Adesto Technologies. “The
industry and market is ready for a supplier that can deliver on today’s products and
offer a roadmap for the next generation. Our roadmap includes higher density and
higher performance devices with lower power and lower cost solutions based on an
advanced memory technology that can scale with CMOS. Only Adesto offers this
capability and customers will be the winners with this industry transformation.”

“Today’s announcement of Adesto’s acquisition of Atmel’s Serial Flash business will
enable it to be a major player in the non-volatile memory business,” said Alan Niebel,
founder and CEO of Web-Feet Research Inc., a semiconductor research company
located in Monterey, CA. “This new sales channel will provide a strong network of
customers, which, together with the acquired IP and design services, will help accelerate
the ramp of their new CBRAM products.”

As part of the agreement, Atmel will provide manufacturing and other transition
services to Adesto for up to one year. A team of Atmel employees supporting the
product lines will also join Adesto.

Adesto’s acquisition of Atmel’s DataFlash and BIOS Flash products includes a 90-day
transition period for customers. From today until December 31, 2012, existing
customers will continue to order production parts through their existing Sales
Representatives and Distributors. Sample parts can be ordered through Atmel or
Adesto’s web site. All other information regarding the acquisition can be found at
Adesto Technologies web site (www.adestotech.com).
