Capitalizing on Intel’s 0.25 µ generation two-bit-per-cell technology, second generation Intel

StrataFlash™ memory products provide 2X the bits in 1X the space, with new features for mainstream
performance. Offered in 128-Mbit (16-Mbyte), 64-Mbit, and 32-Mbit densities, these devices bring
reliable, two-bit-per-cell storage technology to the flash market segment.
Benefits include: more density in less space, high-speed interface, lowest cost-per-bit NOR devices,
support for code and data storage, and easy migration to future devices.
Using the same NOR-based ETOX™ technology as Intel’s one-bit-per-cell products, Intel StrataFlash
memory devices take advantage of over one billion units of manufacturing experience since 1987. As a
result, Intel StrataFlash components are ideal for code and data applications where high density and low
cost are required. Examples include networking, telecommunications, digital set top boxes, audio
recording, and digital imaging.
By applying FlashFile™ memory family pinouts, Intel StrataFlash memory components allow easy design
migrations from existing Word-Wide FlashFile memory (28F160S3 and 28F320S3), and first generation
Intel StrataFlash memory (28F640J5 and 28F320J5) devices.
Intel StrataFlash memory components deliver a new generation of forward-compatible software support.
By using the Common Flash Interface (CFI) and the Scalable Command Set (SCS), customers can take
advantage of density upgrades and optimized write capabilities of future Intel StrataFlash memory devices.
Manufactured on Intel
®
0.25 micron ETOX™ VI process technology, Intel StrataFlash memory provides
the highest levels of quality and reliability.
