28F400BX-T B 28F004BX-T B
Intel’s 4-Mbit Flash Memory Family is an extension of the Boot Block Architecture which includes block-selec-
tive erasure automated write and erase operations and standard microprocessor interface The 4-Mbit Flash
Memory Family 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 4-Mbit flash family is an easy upgrade from Intel’s 2-Mbit Boot Block Flash Memory Family
The Intel 28F400BX-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 28F400BX-T and 28F400BX-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 28F004BX-T B are 8-bit wide 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 28F400BX-T 28F004BX-T provide block locations compatible with
Intel’s MCS-186 family 80286 i386TM i486TM i860TM and 80960CA microprocessors The 28F400BX-B
28F004BX-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 4-Mbit flash devices are very high performance memories which
interface 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 This is critical in handheld battery powered systems
For very low power applications using a 3 3V supply refer to the Intel 28F400BL-T B 28F004BL-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
