PRODUCT FAMILY OVERVIEW
This datasheet contains the specifications for the two branches of products in the SmartVoltage 8-Mbit boot block flash memory family: the -BE/CE suffix products feature a low VCC operating range of 2.7 V–3.6 V; the -BV/CV suffix products offer 3.0 V–3.6 V operation. Both BE/CE and BV/CV products also operate at 5 V for high-speed access times. Throughout this datasheet, the 28F800 refers to all x8/x16 8-Mbit products, while 28F008B refers to all x8 8-Mbit boot block products (but not to the 28F008SA FlashFile™ memory). Also, the term “2.7 V” generally means the full voltage range 2.7 V–3.6 V. 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.
