SAN FRANCISCO -- LSI Logic Corp. and disk-drive maker Seagate Technology LCC today announced plans to develop a "breakthrough" Serial ATA interface for next-generation desktop PC hard disk drives.
Announced at the Intel Developer Forum here, the partnership aims to create a new interface IC, based on LSI Logic's GigaBlazer gigabit-per-second transceiver core and a link layer controller (LLC). The technology will be used in Seagate's next-generation drives, enabling the first full-speed native Serial ATA hard-disk solution, according to the two companies.
The evolutionary Serial ATA interface is expected to be fully adopted by the hard-drive industry by the end of 2003, according to LSI Logic and Seagate. The LSI Logic Serial ATA core technology complies with the specifications set by an industry working group, said the Milpitas, Calif.-based chip maker.
"Today's mass storage customers face more pressure than ever to rapidly develop products in the face of the churn in interface solutions," said David Jones, vice president and general manager of the Storage and Computing ASICs division at LSI Logic in Milpitas, Calif. Jones said LSI Logic and Seagate in Scotts Valley, Calif., are working closely to accelerate development of the 0.18-micron Serial ATA interface chip, which combines the GigaBlaze transceiver with the LLC transport, link, and physical layer interface functions.
Seagate's Brian Dexheimer, executive vice president of sales, marketing and customer service, said the new hard-drive interface is "built for the future from the ground up" to ensure software compatibility with Parallel ATA drives.
