Introduction
This document contains the specifications for the Intel® Advanced+ Boot Block Flash Memory (C3) Stacked Chip Scale Package (SCSP) device. C3 SCSP memory solutions are offered in the following combinations:
• 32-Mbit flash + 8-Mbit SRAM
• 32-Mbit flash + 4-Mbit SRAM
• 16-Mbit flash + 4-Mbit SRAM
• 16-Mbit flash memory + 2-Mbit SRAM

Product Overview
The C3 SCSP device combines flash memory and SRAM into a single package, which provides secure low-voltage memory solutions for portable applications.
The flash memory provides the following features:
• Enhanced security.
• Instant locking/unlocking of any flash block with zero-latency
• A 128-bit protection register that enables unique device identification,
   to meet the needs ofnext generation portable applications.
• Improved 12 V production programming for increased factory throughput.
