Description

Intel's 2-Mbit Flash Memory Family is an extension of the Boot Block Architecture which includes block-selec-tive erasure, automated write and erase operations and standardbmicroprocessor interface. The 28F002BX-B enhances the Boot Block Architecture by adding more density and blocks, x8/x16 input/out-put control, very high speed, low power, an industry-standard ROM compatible pinout and surface mount packaging. The 2-Mbit flash family allows for an easy upgrade to Intel's 4-Mbit Boot Block Flash Memory Family.

The Intel 28F200BX-T/B are 16-bit wide flash memory offerings. These high-density flash memories provide user selectable bus operation for either 8-bit or 16-bit applications. The 28F200BX-T and 28F200BX-B are 2,097,152-bit nonvolatile memories organized as either 262,144 bytes or 131,072 words of information. They are offered in 44-Lead plastic SOP and 56-Lead TSOP packages. The x8/x16 pinout conforms to the industry- standard ROM/EPROM pinout.

The Intel 28F002BX-T/B are 8-bit wide flash memories with 2,097,152 bits organized as 262,144 bytes of information. They are offered in a 40-lead TSOP package, which is ideal for space-constrained portable systems.

These devices use an integrated Command User Interface (CUI) and Write State Machine (WSM) for simplified word/byte write and block erasure. The 28F200BX-T/28F002BX-T provide block locations compatible with Intel's MCSÉ-186 family, 80286, i386TM, i486TM, i860TM and 80960CA microprocessors. The 28F200BX-B/28F002BX-B provide compatibility with Intel's 80960KX and 80960SX families as well as other embedded microprocessors.

The boot block includes a data protection feature to protect the boot code in critical applications. With a maximum access time of 60 ns, these 2-Mbit flash devices are very high-performance memories which inter-face at zero wait-state to a wide range of microprocessors and microcontrollers. A deep power-down mode lowers the total VCC power consumption to 1 mW typical. This is critical in handheld battery-powered systems. For very low-power applications using a 3.3V supply, refer to the Intel 28F200BX-TL/BL, 28F002BX-TL/BL 2-Mbit Boot Block Flash Memory Family datasheet.

Manufactured on Intel's 0.8 micron ETOX III process, the 28F002BX-B provides world-class quality, reliability and cost-effectiveness at the 2-Mbit density level.
