PRODUCT FAMILY OVERVIEW

This datasheet contains the specifications for the two branches of products in the SmartVoltage 2-Mbit boot block flash memory family. These -BV/CV suffix products offer 3.0 V–3.6 V operation and also operate at 5 V for high-speed access times. Throughout this datasheet, the 28F200 refers to all x8/x16 2-Mbit products, while 28F002B refers to all x8 2-Mbit boot block products. Section 1.0 provides an overview of the flash memory family including applications, pinouts and pin descriptions. Sections 2.0 and 3.0 describe the memory organization and operation for these products. Section 4.0 contains the family’s operating specifications. Finally, Sections 5.0 and 6.0 provide ordering and document reference information.
