Product Features
The 3 Volt Advanced Boot Block flash memory, manufactured on Intel's latest 0.18
m
technology, represents a feature-rich solution at overall lower system cost. The 3 Volt Advanced
Boot Block flash memory products in x16 will be available in 48-lead TSOP and 48-ball CSP
packages. The x8 option of this product family will only be available in 40-lead TSOP and 48-
ball BGA* packages. Additional information on this product family can be obtained by
