Susie Inouye, an analyst with Databeans, said the company now estimates ST's 2001 analog revenue at $3.21 billion, edging out TI, which had $3.2 billion in analog revenue last year. Meanwhile, iSuppli reported that ST had analog revenue of $3.38 billion, compared to TI revenue of $3.2 billion.

Databeans, like Scottsdale, Ariz.-based research firm IC Insights Inc., had originally determined that TI had retained its analog lead with estimates of ST's analog revenue at $2.9 billion. Jean Philip Dauvin, chief economist for ST in Geneva, had reported ST analog revenue in 2001 at $3.79 billion. IC Insights is reconsidering its results and expects an update next month.

ST "outperformed the industry in some of their key ASIC markets including consumer and computer," Inouye said.

In addition to ST and TI, Databeans' top five analog vendors in 2001 includes Philips Semiconductor with $1.57 billion, Analog Devices Inc. with $1.56 billion, and Infineon Technologies with $1.25 billion.

The remainder of iSuppli's top five is Philips with $1.57 billion, Analog Devices with $1.56 billion, and Infineon with $1.55 billion.

TI had been the leading analog supplier since 1997.
