Case Temperature Clarification
Internal models indicate that certain elevated case temperatures (Tcase) of the 80331 may cause
elevated field failures in later years of operation. This clarification is precautionary, as Intel has not
seen any failures of the 80331 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 80331
I/O processor, is required. The 80331 should be run with Tcase temperatures that, over the lifetime
of the part, average less than the 95^oC maximum Tcase that is currently specified in the Intel^®
80331 I/O Processor Datasheet (273943).
Tcase recommendations for the 80331:
Frequency
500MHz
667MHz
800MHz
5 year operating life
95^o C
85^o C
79^o C
6 year operating life
93^o C
83^o C
76^o C
7 year operating life
91^o C
81^o C
74^o C
Note: Tcase temperatures in the table reflect an average Tcase temperature over the lifetime of the
product.
Fixed. This issue was fixed in the D-1 stepping of the product. See the Table , “Summary Table of
Changes” on page 9.
