PRODUCT FAMILY OVERVIEW
Throughout this datasheet the 28F400BX refers to
both the 28F400BX-T and 28F400BX-B devices and
28F004BX refers to both the 28F004BX-T and
28F004BX-B devices The 4-Mbit flash memory fam-
ily refers to both the 28F400BX and 28F004BX prod-
ucts This datasheet comprises the specifications for
four separate products in the 4-Mbit flash memory
family Section 1 provides an overview of the 4-Mbit
flash memory family including applications pinouts
and pin descriptions Sections 2 and 3 describe in
detail the specific memory organizations for the
28F400BX and 28F004BX products respectively
Section 4 combines a description of the family’s
principles of operations Finally Section 5 describes
the family’s operating specifications

11 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
or 12V VPP and read operation at 3V or 5V VCC
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
2 5V ProgramErase operation uses proven pro-
gram and erase techniques with 5V g10% ap-
plied to VPP
3 Enhanced circuits optimize performance at 33V
VCC
Refer to the 2 4 or 8 Mbit SmartVoltage Boot Block
Flash Memory Data Sheets for complete specifica-
tions
When you design with 12V VPP boot block products
you should provide the capability in your board de-
sign to upgrade to SmartVoltage products
Follow these guidelines to ensure compatibility
1 Connect DU (WP
on SmartVoltage products) to
a control signal or to VCC or GND
2 If adding a switch on VPP for write protection
switch to GND for complete write protection
3 Allow for connecting 5V to VPP and disconnect
12V from the VPP line if desired
12 Main Features
The 28F400BX28F004BX boot block flash memory
family is a very high performance 4-Mbit (4194304
bit) memory family organized as either 256 KWords
(262144 words) of 16 bits each or 512 Kbytes
(524288 bytes) of 8 bits each
Seven Separately Erasable Blocks
including a
Hardware-Lockable boot block
(16384 Bytes)
Two parameter blocks
(8192 Bytes each) and
Four main blocks
(1 block of 98304 Bytes and 3
blocks of 131072 Bytes) are included on the 4-Mbit
family An erase operation erases one of the main
blocks in typically 24 seconds and the boot or pa-
rameter blocks in typically 10 seconds independent
of the remaining blocks Each block can be indepen-
dently erased and programmed 100000 times
The Boot Block
is located at either the top
(28F400BX-T
28F004BX-T)
or
the
bottom
(28F400BX-B 28F004BX-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
RP
pin is between 114V and 126V the boot block
is unlocked and program and erase operations can
be performed When the RP
pin is at or below 65V
the boot block is locked and program and erase op-
erations to the boot block are ignored
The 28F400BX 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 12mm thick)
package as shown in Figures 3 and 4
The
28F004BX products are available in the 40-Lead
TSOP (12mm thick) package as shown in Figure 5
The Command User Interface (CUI) serves as the
interface between the microprocessor or microcon-
troller and the internal operation of the 28F400BX
and 28F004BX flash memory products
