Case Temperature Clarification
Internal models indicate that certain elevated case temperatures (Tcase) of the Intel® 80333 I/O
processor may cause elevated field failures in later years of operation. This clarification is
precautionary, as Intel has not seen any failures of the 80333 products in the field. Internal
modeling data indicates that the degree of failure risk decreases with lower operating frequency
(i.e. – 500, 667, or 800MHz) and temperature (i.e. – case temperature). If a failure should occur, it
would manifest itself as a hard failure of the I/O processor which can cause a system failure.
A detailed analysis of the system operating conditions, specifically case temperature of the 80333
I/O processor, is required. The 80333 should be run with Tcase temperatures that, over the lifetime
of the part, average less than the 95
80333 I/O Processor Datasheet (305433).
Tcase recommendations for the 80333:
Note: Tcase temperatures in the table reflect an average Tcase temperature over the lifetime of the
product.
