4-MBlT (256K x 16, 512K x 8) LOW-POWER BOOT BLOCK FLASH MEMORY FAMILY

Intel 

28F400BL-T B 28F004BL-T B

Intel’s 4-Mbit Low Power Flash Memory Family is an extension of the Boot Block Architecture which includes

block-selective erasure automated write and erase operations and standard microprocessor interface The

4-Mbit Low Power 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 4-Mbit low power flash family opens a new capability for 3V battery-

operated portable systems and is an easy upgrade to Intel’s 2-Mbit Low Power Boot Block Flash Memory

Family

The Intel 28F400BL-T B are 16-bit wide low power flash memory offerings These high density flash memories

provide user selectable bus operation for either 8-bit or 16-bit applications The 28F400BL-T and 28F400BL-B

are 4 194 304-bit non-volatile memories organized as either 524 288 bytes or 262 144 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 28F004BL-T B are 8-bit wide low power flash memories

with 4 194 304 bits organized as 524 288 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 28F400BL-T 28F004BL-T provide block locations compatible with

Intel’s Low Voltage MCS-186 family i386TM i486TM microprocessors The 28F400BL-B 28F004BL-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 4-Mbit low power flash devices are very high performance memories at

3 3V which interface to a wide range of low voltage microprocessors and microcontrollers A deep power-

down mode lowers the total VCC power consumption to 0 66 mW which is critical in handheld battery powered

systems such as Handy Cellular Phones For very high speed applications using a 5V supply refer to the Intel

28F400BX-T B 28F004BX-T B 4-Mbit Boot Block Flash Memory family datasheet

Manufactured on Intel’s 0 8 micron ETOX III process the 4-Mbit flash memory family provides world class

quality reliability and cost-effectiveness at the 4 Mbit density level
