Actel — американская корпорация, производитель микроэлектроники. Практически единственный массовый производитель высокоёмких программируемых логических интегральных схем (ПЛИС) со встроенной ППЗУ. Штаб-квартира компании располагается Маунтин-Вью, а офисы официальных представителей в Нью-Джерси, Франции, Ирландии, Германии и в России.
В ноябре 2010 года Microsemi Corporation купила Actel
Actel became a publicly traded company in 1985 and became known for its high-reliability and antifuse-based FPGAs, dominating the military and aerospace markets.
In 2000, Actel acquired GateField which expanded Actel's antifuse FPGA offering to include flash-based FPGAs. In 2004, Actel announced it had shipped the one-millionth unit of its flash-based ProASICPLUS FPGA.
In 2005, Actel introduced a new technology known as Fusion to bring FPGA programmability to mixed-signal solutions. Fusion was the first technology to integrate mixed-signal analog capabilities with flash memory and FPGA fabric in a monolithic device.
In 2006, to address the tight power budgets of the portable market, Actel introduced the IGLOO FPGA. The IGLOO family of FPGAs was based on Actel's nonvolatile flash technology and the ProASIC 3 FPGA architecture. Two new IGLOO derivatives were added in 2008: IGLOO PLUS FPGAs with enhanced I/O capabilities, and IGLOO nano FPGAs, the industry's lowest power solution at 2 µW. A nano version of ProASIC3 also became available in 2008.
In 2010, Actel introduced the SmartFusion line of FPGAs. SmartFusion includes both analog components and a programmable flash-based logic fabric within the same chip. SmartFusion was the first FPGA product to additionally include a hard ARM processor core.
Altera and Xilinx are the other key players in the market, however their main focus is on SRAM FPGAs. Lattice Semiconductor is another competitor.
In November 2010, Actel Corporation was acquired by Microsemi Corporation.
