1. Connect DU (WP on SmartVoltage products) to
a control signal or to V or GND.
Throughout this datasheet 28F200BL refers to both
the 28F200BL-T and 28F200BL-B devices and
28F002BL refers to both the 28F002BL-T and
28F002BL-B devices. The 2-Mbit flash family refers
to both the 28F200BL and 28F002BL products. This
datasheet comprises the specifications for four sep-
arate products in the 2-Mbit flash memory family.
Section 1 provides an overview of the 2-Mbit flash
memory family including applications, pinouts and
pin descriptions. Sections 2 and 3 describe in detail
the specific memory organizations for the 28F200BL

1.2 Main Features
The 28F200BL/28F002BL low power boot block
flash memory family is a very low power and very
high performance 2-Mbit (2,097,152 bit) memory
family organized as either 128 Kwords (131,072
words) of 16 bits each or 256 Kbytes (262,144
bytes) of 8 bits each.

4
combines a description of the family’s principles of
operations. Finally, section 5 describes the family’s
operating specifications.
PRODUCT FAMILY
Five Separately Erasable Blocks including a Hard-
ware-Lockable boot block (16,384 Bytes), two pa-
rameter blocks (8,192 Bytes each) and two main
blocks (1 block of 98,304 Bytes and 1 block of
131,072 Bytes) are included on the 2-Mbit family. An
erase operation erases one of the 5 blocks in typi-
cally 3.4 seconds and the boot or parameter blocks
in typically 2.0 seconds, independent of the remain-
ing blocks. Each block can be independently erased
and programmed 10,000 times.

1.1 Designing for Upgrade to
SmartVoltage Products
Today’s high volume boot block products are up-
gradable to Intel’s SmartVoltage boot block prod-
ucts that provide program and erase operation at 5V
The Boot Block is located at either the top
(28F200BL-T, 28F002BL-T) or the bottom
(28F200BL-B, 28F002BL-B) of the address map in
order to accommodate different microprocessor pro-
tocols for boot code location. The hardware locka-
ble boot block provides the most secure code stor-
age. The boot block is intended to store the kernel
code required for booting-up a system. When the

Intel’s SmartVoltage boot block products provide the
following enhancements to the boot block products
described in this data sheet:

1. DU pin is replaced by WP to provide a means
to lock and unlock the boot block with logic sig-
nals.

The 28F200BL products are available in the
ROM/EPROM compatible pinout and housed in the
44-Lead PSOP (Plastic Small Outline) package and
the 56-Lead TSOP (Thin Small Outline, 1.2 mm
thick) package as shown in Figures 3 and 4. The
28F002BL products are available in the 40-Lead
TSOP (1.2 mm thick) package as shown in Figure 5.

you should provide the capability in your board de-
sign to upgrade to SmartVoltage products.
The Command User Interface (CUI) serves as the
interface between the microprocessor or microcon-
troller and the internal operation of the 28F200BL
and 28F002BL flash memory products.
