50 years in electronics: Hall of Fame
Editor Richard Wilson’s Hall of Fame is a personal selection of the most influential companies of the last 50 years.
Programmable logic firms
Altera developed its first programmable array logic (PAL) device in 1984. These evolved into first complex PLDs and then Field-programmable gate arrays (FPGAs), which are logic arrays that can be reprogrammed by the engineer during the design phase and even during operation in the “field”. Altera’s FPGAs are the Cyclone, Arria GX and Stratix series and the MAX series of CPLDs.
Xilinx was founded in 1984 by two Zilog engineers, Bernard Vonderschmitt and Ross Freeman, who wanted to develop his idea of a programmable device. Xilinx sold its first chip in 1985. After four years of venture funding the fabless chip company went public in 1989. Today its FPGAs include Spartan, Virtex and the latest Xilinx 7 series. As well as the CoolRunner-II CPLDs.
Unlike the traditional, SRAM-based programmable technology used by Altera and Xilinx, in 1985 Actel created its first FPGA using antifuse-based technology. It later acquired the technology to create the first flash-based FPGAs. Its FPGAs include the Igloo and ProAsic familes, as well as the SmartFusion mixed-signal programmable devices.
Lattice Semiconductor was founded in 1983, by C. Norman Winningstad, Rahul Sud, and Ray Capece. It developed its own programmable technology for CPLDs and FPGAs. Its FPGAs include the LatticeECP3 series and the LatticeXP2 series, which combines a look-up table based FPGA fabric with flash non-volatile cells. Its CPLDs are the MachXO series and the ispMACH 4000ZE series.
Monolithic Memories Inc. (MMI) was founded in 1969 by a former Fairchild Semiconductor engineer. It was acquired by Advanced Micro Devices (AMD) in 1987. It was soon spun off by the microprocessor firm as Vantis, which was later bought by Lattice Semiconductor.
