Description

The Smart 3 Advanced Boot Block, manufactured on Intel's latest 0.25 µ technology, represents a feature-rich solution at overall lower system cost. 28F400B3 incorporate low voltage capability(2.7 V 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 1.65 V, which significantly reduces system active power and interfaces to 1.65 V 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 a cost-effective, monolithic code plus data storage solution. 28F400B3 will be available in 40-lead and 48-lead TSOP and 48-ball µBGA* packages.
