The Intel® Advanced+ Book Block Flash Memory (C3) device, manufactured on Intel’s latest
0.13 µm and 0.18 µm technologies, represents a feature-rich solution for low-power applications.
The C3 device incorporates low-voltage capability (3 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 (FDI) software and you have a cost-
effective, flexible, monolithic code plus data storage solution. Intel® Advanced+ Boot Block Flash
Memory (C3) 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.
Notice: This specification is subject to change without notice. Verify with your local Intel sales
office that you have the latest datasheet before finalizing a design.
