Flash Technology
The new Smart 3 Advanced Boot Block, manufactured on Intel’s latest 0.4μ technology, represents a feature-
rich solution at overall lower system cost. Smart 3 flash memory devices incorporate low voltage capability
(2.7V read, program and erase) with high-speed, low-power operation. Several new features have been
added, including the ability to drive the I/O at 1.8V, which significantly reduces system active power and
interfaces to 1.8V controllers. A new blocking scheme enables code and data storage within a single device.
Add to this the Intel-developed Flash Data Integrator (FDI) software and you have the most cost-effective,
monolithic code plus data storage solution on the market today. Smart 3 Advanced Boot Block Word-Wide
products will be available in 48-lead TSOP and 48-ball μBGA* packages. Additional information on this
product family can be obtained by accessing Intel’s WWW page: http://www.intel.com/design/flcomp.
