Flash Technology
The 3 Volt Advanced+ Boot Block Flash memory, manufactured on Intel’s latest 0.18 µ
technology, represents a feature-rich solution for low power applications. 3 Volt Advanced+
Boot Block Flash memory devices incorporate low voltage capability (2.7 V read, program and
erase) with high-speed, low-power operation. Flexible block locking allows any block to be
independently locked or unlocked. Add to this the Intel
®
Flash Data Integrator (IFDI) software
and you have a cost-effective, flexible, monolithic code plus data storage solution. Intel
®
3 Volt
Advanced+ Boot Block products will be available in 48-lead TSOP, 48-ball CSP, and 64-ball
Easy BGA packages. Additional information on this product family can be obtained by
accessing the Intel
®
Flash website: http://www.intel.com/design/flash.
