Datasheet
Product Features
The Intel
Advanced Boot Block Flash Memory (B3) device, manufactured on the Intel 0.13
m
and 0.18
m technologies, represents a feature-rich solution at overall lower system cost. The
B3 device in x16 will be available in 48-lead TSOP and 48-ball CSP packages. The x8 option of
this product family is available only in 40-lead TSOP and 48-ball BGA* packages. Additional
