Description

Intel's 28F002BL-B is an extension of the Boot Block Architecture which includes block-selective erasure, automated write and erase operations and standard microprocessor interface. The 2-Mbit Flash Memory Family enhances the Boot Block Architecture by adding more density and blocks,x8/x16 input/output control, very low power, very high speed, an industry standard ROM compatible pinout and surface mount packaging. The 2-Mbit Low Power Flash Family opens a new capability for 3V battery-oper-ated portable systems and allows for an easy upgrade to Intel's 4-Mbit Low Power Boot Block Flash Memory Family.

The Intel 28F200BL-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 28F200BL-T and 28F200BL-B are 2,097,152-bit non-volatile 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 28F002BL-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 28F200BL-T/28F002BL-T provide block locations compatible with Intel's low voltage MCS-186 family, i386TM, i486TM microprocessors. The 28F200BL-B/28F002BL-B provide compatibility with Intel's 80960KX and 80960SX families as well as other low voltage embedded microproces-sors.

The boot block includes a data protection feature to protect the boot code in critical applications. With a maximum access time of 150 ns, these 2-Mbit flash devices are very high performance low power memories which interface to a wide range of low power microprocessors and microcontrollers. A deep power-down mode lowers the total VCC power consumption to 0.66 mW. This is critical in handheld battery powered systems such as Handy Phones. For very high speed applications using a 5V supply, refer to the Intel 28F200BX-T/B,28F002BX-T/B 2-Mbit Boot Block Flash Memory Family datasheet.

Manufactured on Intel's 0.8 micron ETOX III process, the 2-Mbit low power flash memory family provides world class quality, reliability and cost-effectiveness at the 2-Mbit density level.
