SST part numbers

Silicon Storage Technology (SST25/SST26/SST39 NOR flash) was acquired by Microchip Technology in 2010.

SST is now Microchip Technology (2010). We quote SST parts — current, obsolete and end-of-life — and parts that carry older SST markings. See also all Microchip Technology part numbers.

Frequently asked questions

Is SST still in business?

Silicon Storage Technology (SST25/SST26/SST39 NOR flash) was acquired by Microchip Technology in 2010.

Can I still buy SST parts?

Yes. PartnerSemi quotes SST part numbers, including obsolete and end-of-life parts and parts with old SST markings. Send the part number and quantity; we reply with price, lead time, date code and origin. We are an independent distributor, not an authorized SST or Microchip Technology distributor.

PartnerSemi is not affiliated with SST or Microchip Technology. Brand names are used to identify parts only.
