Chips and Technologies
Résumé
Chips and Technologies, Inc. (C&T), was an early fabless semiconductor company founded in Milpitas, California, in December 1984 by Gordon A. Campbell and Dado Banatao.
Its first product, announced September 1985, was a four chip EGA chipset that handled the functions of 19 of IBM's proprietary chips on the Enhanced Graphics Adapter. By that November's COMDEX, more than a half dozen companies had introduced EGA-compatible boards based on C&T's chipset. This was followed by chipsets for PC motherboards and other computer graphics chips.
C&T was acquired by Intel in 1997, primarily for its graphics chip business.
Former members of C&T founded Asiliant Technologies in January 2000 to continue the support of the CHIPS 65545, 65550, 65555, 69000, 69030, and other notebook and LCD oriented graphics ICs. Intel licensed the rights to build, sell, and service the C&T chips to Asiliant. Asiliant manufactured and sold C&T components for the next few years until it closed.
C&T SuperMath J38700DX was an 80387DX compatible FPU coprocessor.
C&T also designed a 386-compatible microprocessor known as the Super386 38600DX/38600SX using clean room design techniques, but this chip never enjoyed as much success as the 386 CPUs produced by Intel, AMD, and Cyrix. C&T 38605DX had 512 byte cache, but the 144 pin PGA package was incompatible with 386 socket.
NEAT chipset
82C100 - IBM PS/2 Model 30 and Super XT Computer Chip - Released in 1987, compatible with 8086, 80C86, V30, 8088, 80C88, V20 CPUs. Compatible with all PC/XT functional units: 8284, 8288, 8237, 8259, 8254, 8255, DRAM controller, SRAM controller, Keyboard controller, Parity Generation and Configuration registers. Additionally features EMS control, dual clock and power management. It supports up to 2.5 MB RAM.
82C206 chip, introduced by C&T in 1986 and the core of the NEAT (New Enhanced AT) chipset. This chip, like its predecessor the 82C100, provided equivalent functionality to the TTL chips on the PC/AT's mainboard, namely: the 82284 clock generator, the 82288 bus controller, the 8254 Programmable Interval Timer, the two 8259 Programmable Interrupt Controllers, the two 8237 DMA controllers, the MC146818 NVRAM/RTC chip.
