TI begins producing DSPs using 90nm technology

Posted: 10 Nov 2004 ?? ?Print Version ?Bookmark and Share

After months of telling the industry of its ambitious plans, Texas Instruments Inc. has begun volume production on 1GHz digital signal processors (DSPs) using 90nm process technology.

The semiconductor maker said last month it was ramping up 90nm production at several sites, the first being its Kilby fab located on its Dallas campus. TI also signed a foundry deal with Chinese foundry provider SMIC to produce 90nm chips.

TI's initial foray into 90nm technology involves its TMS320C6414T, TMS320C6415T and TMS320C6416T DSPs. The company says migrating the 720MHz versions of these parts to 90nm process technology reduces cost 50 percent compared to the 130nm technology used previously.

"TI is experiencing a lot of demand for these 90nm devices to enable higher channel density in communications infrastructure, a market that has been traditionally very strong for the TMS320C64x generation of DSPs as well as the exploding market of video infrastructure," said Gene Frantz, a principal fellow of Texas Instruments, in a statement.

The 1GHz DSPs are now manufactured on 200mm copper wafers; however TI recently qualified the 90nm process in its DMOS6 advanced 300mm manufacturing facility to add manufacturing capacity and lower costs.

List price for the 720MHz C6415T with 1MB of on-chip memory starts at $99.97 in quantities of 10,000.
