Intel stops making chip

August 28, 1991|By New York Times News Service

SAN FRANCISCO -- Intel Corp. said yesterday that it had temporarily halted production of its 50 megahertz 486 chip, the new high-speed version of its most powerful microprocessor, because of problems in manufacturing and testing.

Intel said that it believed the problem could be solved quickly, possibly in a few days.

In the meantime, the company has asked computer-makers to suspend shipments of personal computers that use the chip.

The problem, which is linked to high-temperature and high-frequency use of the chip, causes software to hang up. The problem could result in the loss of data without warning.

Some computer manufacturers have said the chip has a problem with heat when operating at its highest speed, but Intel has ruled that out.

Intel will have a "test screen in place this week which will allow us to screen out parts that have this problem and allow us to resume shipments shortly," said James Jarrett, a spokesman for Intel.

The company will alter subsequent production of the chip to eliminate the problem, Mr. Jarrett said.
