PCN MPG/SR/2003004

MATERIAL CHANGE FOR ALL ST ZEROPOWER AND TIMEKEEPER NVRAMS IN DIP24 AND DIP28

CAPHAT PACKAGES

WHAT IS THE CHANGE?

STMicroelectronics is implementing our new ECOPACK

Lead-free plating on all 24-lead and 28-lead

CAPHAT™ DIP packaged ZEROPOWER

and TIMEKEEPER

NVRAM devices. These devices will

convert from Tin-Lead to pure Tin-plated leadframes.

Note: Here, the term “Lead-free” means free of the element, Lead.

The following devices are affected:

For new system designs and qualifications, it is recommended that the Lead-free versions of these prod-

ucts be used.

WHY?

These changes are being implemented to make the devices more environmentally friendly.

WHEN?

Production parts could begin shipping as soon as April 1, 2004. Samples are available now. Qualification

reports are available for each product family.

Once ST commences production of these Lead-free parts, it will cease production of the versions contain-

ing Lead, so customers are strongly encouraged to qualify the Lead-free parts in a timely manner.

Any last time orders for Leaded products needs to placed by Jan 31, 2004.

MPG/SR/2003004 HOW WILL THE CHANGE BE QUALIFIED? Qualification is being done according to STMicroelectronics Corporate procedure. IMPACT ESTIMATION AT USER'S SIDE These changes should have no impact because the plating technologies used are compatible with both Leaded and Lead-free assembly processes. ABOUT TRACEABILITY The Lead-free parts can be identified in three ways: The letter E (as in ECOPACK®) will appear in the brand.
