Product Description
Intel's advanced SmartVoltage 2-, 4- and 8-Mbit flash memories offer users optimal benefits in a mid-density flash. Using a cost-effective and highly advanced process technology, the SmartVoltage 2-, 4- and 8-Mbit products offer new capabilities in establishing a standard in flash memory. You can choose among read/write voltages, x8 or x8/x16 data bus, hardware reset, high performance read access, transparent automated erase/program algorithms and absolute write protection.

The SmartVoltage 2-, 4- and 8-Mbit memory architecture is ideal for integrating boot ROM, EEPROM-like parameter storage and bulk flash code storage - with optimized memory blocks for each need. Designers can incorporate this tuned architecture in a selection of footprint compatible densities, including 2-Mbit, 4-Mbit and 8-Mbit.

The industry today demands flash memory products that have advanced features, are cost effective, and deliver flexibility and ease of use. Intel delivers these capabilities in 40-pin and greater TSOP and PSOP packages. Plus, only Intel offers voltage options for standard 5V read, down to 2.7V read for low-power current and future needs in one product offering at no price premium. In addition, Intel offers high-throughput efficiency in manufacturing with 12V programming, and simplicity of board design with 5V writes.

Intel's SmartVoltage 2-, 4-, and 8-Mbit products provide high integration for space-constrained embedded applications, low voltage for portable applications, and absolute block locking for easy system recovery in PC BIOS applications.
