In 1991, Atmel expanded the Colorado facility after acquiring Concurrent Logic, a field-programmable gate array (FPGA) manufacturer. The company made its initial public offering (IPO) in 1991 which yielded more than US$65 million. 1994 saw Atmel enter the microprocessor market. The first Atmel flash memory microcontroller was based on the Intel 8051.atmel.com, "Atmel’s Self-Programming Flash Microcontrollers", Whitepaper. The controller executed an instruction for every clock cycle, as opposed to the 12 cycles that legacy 8051 parts required.atmel.com, "8051 Single Cycle Core Microcontrollers", Flyer. In 1994, Atmel purchased the EEPROM assets of Seeq Technology (LSI Corporation acquired the rest of Seeq in 1999). In 1995, Atmel was among the first companies to license the ARM architecture, creating its AT91 family of devices, followed by the SAM family, and more recently a full selection of Cortex-based solutions, including ones based on the ultra-low-power ARM Cortex-M4. Atmel now has dozens of families of ARM-based devices. In 1995, Atmel acquired the pan-European chipmaker European Silicon Structures (ES2) and thus gained a fabrication facility in Rousset, France. Atmel built a new fab alongside the existing ES2 fab. This business unit was named Atmel-ES2. Atmel acquired Digital Research in Electronic Acoustics and Music (DREAM) in 1996. Atmel formed a design team in Trondheim, Norway to develop the Atmel AVR line of RISC microcontrollers. This team combined technology of former students at the Norwegian University of Science and Technology with Atmel's expertise in flash memory. These 8-bit Harvard architecture chips were first developed in 1996. The AVR chip is the basis of most Arduino open-source development boards. In 1998, Atmel purchased part of TEMIC from Vishay Intertechnology, which provided them with a fab in Germany as well as part of MHS from Vishay that gave them a fab in Nantes, France.
