Package Family
Datasheet
Product Features
The 3 Volt Intel
Advanced+ Boot Block Flash Memory (C3) Stacked-Chip Scale Package
(Stacked-CSP) device delivers a feature-rich solution for low-power applications. The C3
Stacked-CSP memory device incorporates flash memory and static RAM in one package with
low voltage capability to achieve the smallest system memory solution form-factor together with
high-speed, low-power operations. The C3 Stacked-CSP memory device offers a protection
register and flexible block locking to enable next generation security capability. Combined with
the Intel
Flash Data Integrator (Intel
FDI) software, the C3 Stacked-CSP memory device
provides a cost-effective, flexible, code plus data storage solution.
