28F200BL-TB Datasheet, PDF (2/42 Pages) Intel Corporation – 2-MBIT (128K x 16, 256K x 8)LOW-POWER BOOT BLOCK FLASH MEMORY FAMILY

28F200BL-T B 28F002BL-T B
Intel’s 2-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
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 i386^TM i486^TM 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 V_CC 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
