This datasheet contains 4-, 8-, and 16-Mbit 3 Volt FlashFile memory specifications. Section 1.0 provides a flash memory overview. Sections 2.0, 3.0, 4.0, and 5.0 describe the memory organization and functionality. Section 6.0 covers electrical specifications for commercial and extended temperature product offerings. Ordering information is provided in Section 7.0. Finally, the 3 Volt FlashFile memory family documentation also includes application notes and design tools which are referenced in Section 8.0.

Product Overview

The 3 Volt FlashFile memory family provides density upgrades with pinout compatibility for the 4- , 8-, and 16-Mbit densities. The 28F004S3, 28F008S3, and 28F016S3 are high-performance memories arranged as 512 Kbyte, 1 Mbyte, and 2 Mbyte of eight bits. This data is grouped in eight, sixteen, and thirty-two 64-Kbyte blocks which are individually erasable, lockable, and unlockable insystem. Figure 5 illustrates the memory organization.
