Description of Change:
Silicon Labs announces an End of Life (EOL) and Last Time Buy (LTB) for all CMEMS products. This
includes Si501, Si502, Si503, Si504, and Si50122 products.
Due to changes in market conditions, Silicon Labs has decided to discontinue its CMEMS product
line. This decision affects CMEMS products only. All Si5xx XO/VCXO products will continue to be
fully supported and are available in mass production.
The key dates for this EOL are listed in the table below:
EOL Date
6/30/2015
Last Time Buy (Order) Date
12/31/2015
EOL Effective Date
6/30/2016
All orders, including Last Time Buy orders, for these devices must be placed by the Last Order Date
(31 December 2015) and have a customer requested delivery date prior to the EOL Effective date
(30 June 2016). Any orders with a customer requested delivery date between the Last Order Date
and the EOL Effective Date will be non-cancellable and non-returnable (NCNR). Any custom parts
are also NCNR. Orders with a CRD date beyond the EOL Effective Date (30 June 2016) will not be
accepted.
If you have questions about this EOL, please contact your Silicon Labs sales representative. A list of
Silicon Labs sales representatives is available at

Product Identification:
Si501, Si502, Si503, and Si504 products are custom devices. Part numbers ending with an “R” indicate tape and
reel (T&R) packaging. The third character from the end (fourth character from the end if T&R) indicates the
product package size which is a key parameter for determining an appropriate replacement option.
Silicon Labs Si510, Si512, and Si514 crystal oscillator (XO) products are compatible with CMEMS devices in
5x7mm and 3.2x5mm package sizes as shown in the table below.
It is also possible to use a small crystal and Si51210 “Tiny Clock” clock generator (1.2x1.4mm) for any CMEMS
package size to achieve the oscillator function in a small PCB footprint. Please contact Silicon Labs for more
information about Tiny Clock solutions.
Drop-in compatible solutions for some of these devices are also available from other suppliers. If needed,
please contact Silicon Labs for guidance regarding second-sourcing options.
