2-MBIT (128K x 16, 256K x 8) BOOT BLOCK FLASH MEMORY FAMILY

Intel 

28F200BX-T B 28F002BX-T B

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 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 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 3 3V supply refer to the Intel 28F200BX-TL BL 28F002BX-TL BL
