Description of Change:
Si8540 Qualification Improvement to MSL2A and Datasheet update to revision 1.1.
Reason for Change:
Originally sold as an Integration Associates product (“IA2410”), the Si8540 has been re-qualified for
full production release according to Silicon Laboratories corporate policies, resulting in
improvement from MSL3 to MSL2A moisture sensitivity level.
Impact on Form, Fit, Function, Quality, Reliability:
Moisture sensitivity level (MSL) has been improved from MSL3 to MSL2A for the SOT-23 package
(Si8540-B-FW). The SOIC package was already qualified for MSL2A. MSL specifies the maximum
time period for which the device can be exposed to ambient room conditions before it must be
mounted and reflowed onto the target printed circuit board. While MSL3 only allows 168 hours out
of bag, MSL2A allows up to 4 weeks. This enables greater manufacturing flexibility for customers.
The datasheet has been re-released to reflect the MSL2A qualification results. The Si8540 updated
datasheet is available at www.silabs.com.
Product Identification:
Affected part numbers are:
Si8540-B-FS/Si8540-B-FSR (SOT-23 package) and Si8540-B-FW/Si8540-B-FWR (SOIC package).
Last Date of Unchanged Product: N/A, requalified product is already shipping
Qualification Samples:
Samples are available now. Please contact your local Silicon Laboratories sales representative to
order samples. A list of authorized sales representatives may be found at www.silabs.com.
