C3 Discrete
1.0
Introduction
This datasheet contains the specifications for the Numonyx™ Advanced+ Boot Block
Flash Memory (C3) device family, hereafter called the C3 flash memory device. These
flash memories add features such as instant block locking and protection registers that
can be used to enhance the security of systems.
The Numonyx™ 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 Numonyx™
Flash Data Integrator (Numonyx™ FDI) software and you have a cost-effective,
flexible, monolithic code plus data storage solution. Numonyx™ Advanced+ Boot Block
Flash Memory (C3) products are available in 48-lead TSOP, 48-ball CSP, and 64-ball
Easy BGA packages. Additional information on this product family can be obtained from
