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.

• 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.

• 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.

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).
