Corrections: “This pin not available on 44-PSOP” inaccurate statement removed from pin
description for WP# pin; Spec “tQWL” corrected to “tQVVL;” intelligent identifier values
corrected; Intel386™ EX block diagram updated because new 386 specs require less
glue logic.

2-MBIT SmartVoltage BOOT BLOCK FAMILY
1.0 PRODUCT FAMILY OVERVIEW
This datasheet contains the specifications for the
two branches of products in the SmartVoltage
2-Mbit boot block flash memory family. These
-BV/CV suffix products offer 3.0 V–3.6 V operation
and also operate at 5 V for high-speed access
times. Throughout this datasheet, the 28F200
refers to all x8/x16 2-Mbit products, while
28F002B refers to all x8 2-Mbit boot block
products. Section 1.0 provides an overview of the
flash memory family including applications, pinouts
and pin descriptions. Sections 2.0 and 3.0
describe the memory organization and operation
for these products. Section 4.0 contains the
family’s operating specifications. Finally, Sections
5.0 and 6.0 provide ordering and document
reference information.
1.1 New Features in the
SmartVoltage Products
The SmartVoltage boot block flash memory family
offers identical operation with the BX/BL 12 V
program products, except for the differences listed
below. All other functions are equivalent to current
products, including signatures, write commands,
and pinouts.
Enhanced circuits optimize low VCC
performance, allowing operation down to
VCC = 3.0 V.
If you are using BX/BL 12 V VPP boot block
products today, you should account for the
differences listed above and also allow for
connecting 5 V to VPP and disconnecting 12 V
from VPP line, if 5 V writes are desired.
1.2 Main Features
Intel’s SmartVoltage technology is the most
flexible voltage solution in the flash industry,
providing two discrete voltage supply pins: VCC for
read operation, and VPP for program and erase
operation. Discrete supply pins allow system
designers to use the optimal voltage levels for
their design. This product family, specifically the
28F200BV/CV, and 28F002BV provide program/
erase capability at 5 V or 12 V. The 28F200BV/CV
and 28F002BV allow reads with VCC at 3.3 V ±
0.3 V or 5 V. Since many designs read from the
flash memory a large percentage of the time, read
operation using the 3.3 V ranges can provide great
power savings. If read performance is an issue,
however, 5 V VCC provides faster read access
times.
WP# pin has replaced a DU (Don’t Use) pin.
Connect the WP# pin to control signal or to
VCC or GND (in this case, a logic-level signal
can be placed on DU pin). Refer to Tables 2
and 9 to see how the WP# pin works.
5 V program/erase operation has been added.
If switching VPP for write protection, switch to
GND (not 5 V) for complete write protection.
To take advantage of 5 V write-capability,
allow for connecting 5 V to VPP and
disconnecting 12 V from VPP line.
For program and erase operations, 5 V VPP
operation eliminates the need for in system
voltage converters, while 12 V VPP operation
provides faster program and erase for situations
where 12 V is available, such as manufacturing or
designs where 12 V is in-system. For design
simplicity, however, just hook up VCC and VPP to
the same 5 V ± 10% source.
The 28F200/28F002B boot block flash memory
family is a high-performance, 2-Mbit (2,097,152
bit) flash memory family organized as either
256 Kwords of 16 bits each (28F200 only) or
512 Kbytes of 8 bits each (28F200 and 28F002B).
