GlobalFoundries and Microchip Announce Microchip’s 28nm SuperFlash® Embedded Flash Memory Solution in Production

Widely deployed non-volatile memory (NVM) solution is optimized for microcontrollers, smartcards, and IoT chips

CHANDLER, Ariz., and MALTA, N.Y., Sept. 27, 2023 (GLOBE NEWSWIRE) — GlobalFoundries (GF) (Nasdaq: GFS) and Microchip Technology (Nasdaq: MCHP), via its Silicon Storage Technology (SST) subsidiary, today announces the immediate release to production of the SST ESF3 third-generation embedded SuperFlash non-volatile memory (NVM) solution in the GF 28SLPe foundry process.

GF has established a new industry benchmark for implementing SST’s widely deployed ESF3 SuperFlash technology. This implementation delivers the following capabilities and benefits:

  • Lowest cost 28nm HKMG ESF3 solution with only 10 masks added, incl. true 5V IO CMOS devices
  • Highly competitive SST ESF3 bitcell size of only 0.04 micron squared
  • Operating temperature rating of -40 degrees C to 125 degrees C
  • Sub-25 nanosecond (ns) read access times, 10 microsecond program times and 4 millisecond erase times
  • Endurance exceeding 100,000 program/erase cycles
  • No impact to design flows using GF 28SLPe platform-qualified IP (EG flow)
  • Immediate availability of off-the-shelf macros, from 4 megabits (Mb) to 32 Mb
  • Access to custom macro design support from SST or GF

Use cases for embedded flash are exploding with the drive for increased intelligence at the edge.  Embedded memory for secure code storage, over-the-air-updates and enhanced functionality is on the rise in a wide range of applications in Home and Industrial IoT as well as Smart Mobile Devices. Innovative platforms are required to meet these needs.

“GF is proud to partner with SST to develop, qualify, and release to production this impressive embedded NVM solution on our robust 28SLPe platform,” said Mike Hogan, Chief Business Unit Officer at GF. “GF’s customers are finding this combination of high performance, excellent reliability, IP availability, and cost effectiveness to be ideal for advanced MCUs, complex smart cards, and IoT chips for consumer and industrial products.”

“SST and GF have partnered closely over the last decade to integrate and productize SST’s industry-standard ESF1 and ESF3 embedded Flash technologies into GF’s 130nm BCD, 55nm, 40nm, and now 28nm foundry platforms,” added Mark Reiten, vice president of SST, Microchip’s licensing business unit. “We are excited by the leadership position GF is establishing for the broadest offering of embedded NVM solutions and expect our close partnership to deliver additional breakthroughs over the coming decade.”

SST is exhibiting its embedded Flash technology in the IP partner area during today’s GF Technology Summit in Munich.
