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 standard microprocessor interface The 2-Mbit Flash
Memory Family enhances the Boot Block Architecture by adding more density and blocks x8x16 inputout-
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-TB 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
2097152-bit nonvolatile memories organized as either 262144 bytes or 131072 words of information They
are offered in 44-Lead plastic SOP and 56-Lead TSOP packages The x8x16 pinout conforms to the industry-
standard ROMEPROM pinout
The Intel 28F002BX-TB are 8-bit wide flash memories with 2097152 bits organized as 262144 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
wordbyte write and block erasure The 28F200BX-T28F002BX-T provide block locations compatible with
Intel’s MCS -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 33V supply refer to the Intel 28F200BX-TLBL 28F002BX-TLBL
