Product Description
Intel's symmetrically blocked 28F008SA - the first flash memory optimized for solid state and data file storage - provides new opportunities for system differentiation. Using Intel's third-generation ETOX(TM) flash process, the 28F008SA offers the most cost-effective solution for read/write nonvolatile random-access system memory.

Combined with file management software such as Microsoft's* Flash File System, the 28F008SA's symmetrically blocked architecture and extended cycling provide high-performance disk-emulation capability. High-performance access times of 85 and 120ns deliver instant-on utility for resident application and operating system software. In addition, in-system update and upgrade flexibility eliminate the risk of software obsolescence.

The 28F008SA is a high-performance 8-Mbit (8,388,608-bit) flash memory organized as one Mbyte (1,048,576 bytes) of eight bits each. It contains 16 64-Kbyte (65,536-byte) blocks. Each block is separately erasable and capable of 100,000-byte write-block erase cycles. On-chip automation dramatically simplifies software algorithms and frees the system microprocessor to service higher-priority tasks. An enhanced system interface allows switching the 28F008SA into a deep powerdown mode during periods of inactivity and gives a hardware indication of the status of the internal Write State Machine.

High-speed access times result in minimal wait-state interfacing to microprocessor buses. Advanced TSOP packaging allows maximum density/in2.
