SHARP’s LH28F800BVE-TV85 Flash memory with Smart5 technology is a high-density, low-cost, nonvolatile, read/write
storage solution for a wide range of applications. LH28F800BVE-TV85 can operate at VCC=4.5V-5.5V and VPP=4.5V-5.5V.
Its low voltage operation capability realize battery life and suits for cellular phone application.
Its Boot, Parameter and Main-blocked architecture, flexible voltage and extended cycling provide for highly flexible
component suitable for portable terminals and personal computers. Its enhanced suspend capabilities provide for an ideal
solution for code + data storage applications. For secure code storage applications, such as networking, where code is either
directly executed out of flash or downloaded to DRAM, the LH28F800BVE-TV85 offers two levels of protection: absolute
protection with VPP at GND, selective hardware boot block locking. These alternatives give designers ultimate control of their
code security needs.
The LH28F800BVE-TV85 is manufactured on SHARP’s 0.35µm ETOXTM* process technology. It come in industry-standard
package: the 48-lead TSOP ideal for board constrained applications.

Key enhancements of LH28F800BVE-TV85 Smart5 Flash
memory are:
Internal VCC and VPP detection Circuitry automatically
configures the device for optimized read and write
operations.
•Smart5 Technology
•Enhanced Suspend Capabilities
•Boot Block Architecture
A Command User Interface (CUI) serves as the interface
between the system processor and internal operation of the
device. A valid command sequence written to the CUI
initiates device automation. An internal Write State
Machine (WSM) automatically executes the algorithms
and timings necessary for block erase and word/byte write
operations.
Please note following important differences:
•VPPLK has been lowered to 1.5V to support 4.5V-5.5V
block erase and word/byte write operations. The VPP
voltage transitions to GND is recommended for
designs that switch VPP off during read operation.
A block erase operation erases one of the device’s 32K-
word blocks typically within 0.39s (5V VCC, 12V VPP),
4K-word blocks typically within 0.25s (5V VCC, 12V
VPP) independent of other blocks. Each block can be
independently erased 100,000 times. Block erase suspend
mode allows system software to suspend block erase to
read or write data from any other block.
•To take advantage of Smart5 technology, allow VCC
and VPP connection to 4.5V-5.5V.
1.2 Product Overview
The LH28F800BVE-TV85 is a high-performance 8M-bit
Smart5 Flash memory organized as 1M-byte of 8 bits or
512K-word of 16 bits. The 1M-byte/512K-word of data is
arranged in two 8K-byte/4K-word boot blocks, six 8K-
byte/4K-word parameter blocks and fifteen 64K-byte/32K-
word main blocks which are individually erasable in-
system. The memory map is shown in Figure 3.
Writing memory data is performed in word/byte
increments of the device’s 32K-word blocks typically
within 8.4µs (5V VCC, 12V VPP), 4K-word blocks
typically within 17µs (5V VCC, 12V VPP). Word/byte
write suspend mode enables the system to read data or
execute code from any other flash memory array location.
Smart5 technology provides a choice of VCC and VPP
combinations, as shown in Table 1, to meet system
performance and power expectations. VPP at 4.5V-5.5V

reduces active current when the device is in static mode
(addresses not switching). In APS mode, the typical ICCR

.
current is 1mA at 5V VCC
.
The status register indicates when the WSM’s block erase
or word/byte write operation is finished.
When CE# and RP# pins are at VCC, the ICC CMOS
standby mode is enabled. When the RP# pin is at GND,
deep power-down mode is enabled which minimizes
power consumption and provides write protection during
reset. A reset time (tPHQV) is required from RP# switching
high until outputs are valid. Likewise, the device has a
wake time (tPHEL) from RP#-high until writes to the CUI
are recognized. With RP# at GND, the WSM is reset and
the status register is cleared.
The RY/BY# output gives an additional indicator of WSM
activity by providing both a hardware signal of status
(versus software polling) and status masking (interrupt
masking for background block erase, for example). Status
polling using RY/BY# minimizes both CPU overhead and
system power consumption. When low, RY/BY# indicates
that the WSM is performing a block erase or word/byte
write. RY/BY#-high Z indicates that the WSM is ready for
a new command, block erase is suspended (and word/byte
write is inactive), word/byte write is suspended, or the
device is in deep power-down mode.
The device is available in 48-lead TSOP (Thin Small
Outline Package, 1.2 mm thick). Pinout is shown in Figure
2.
The access time is 85ns (tAVQV) over the commercial
temperature range (0°C to +70°C) and VCC supply voltage
range of 4.5V-5.5V.

Commands are written using standard microprocessor
write timings. The CUI contents serve as input to the
WSM, which controls the block erase and word/byte write.
The internal algorithms are regulated by the WSM,
including pulse repetition, internal verification and
margining of data. Addresses and data are internally latch
during write cycles. Writing the appropriate command
outputs array data, accesses the identifier codes or outputs

Interface software that initiates and polls progress of block
erase and word/byte write can be stored in any block. This
code is copied to and executed from system RAM during
flash memory updates. After successful completion, reads
are again possible via the Read Array command. Block
erase suspend allows system software to suspend a block
erase to read/write data from/to blocks other than that
which is suspend. Word/byte write suspend allows system
software to suspend a word/byte write to read data from
any other flash memory array location.

The first task is to write the appropriate read mode
command (Read Array, Read Identifier Codes or Read
Status Register) to the CUI. Upon initial device power-up
or after exit from deep power-down mode, the device
automatically resets to read array mode. Six control pins
dictate the data flow in and out of the component: CE#,
OE#, WE#, RP#, WP# and BYTE#. CE# and OE# must be
driven active to obtain data at the outputs. CE# is the
device selection control, and when active enables the
selected memory device. OE# is the data output
(DQ -DQ ) control and when active drives the selected
erased or written. Time t
is required after RP# goes

written.
As with any automated device, it is important to assert
RP# during system reset. When the system comes out of
reset, it expects to read from the flash memory. Automated
flash memories provide status information when accessed
during block erase or word/byte write modes. If a CPU
reset occurs with no flash memory reset, proper CPU
initialization may not occur because the flash memory
may be providing status information instead of array data.
SHARP’s flash memories allow proper CPU initialization
following a system reset through the use of the RP# input.
In this application, RP# is controlled by the same RESET#
signal that resets the system CPU.

3.5 Read Identifier Codes Operation
3.6 Write
The read identifier codes operation outputs the
manufacturer code and device code (see Figure 4). Using
the manufacturer and device codes, the system CPU can
automatically match the device with its proper algorithms.
Writing commands to the CUI enable reading of device
data and identifier codes. They also control inspection and
clearing of the status register. When V =4.5V-5.5V and

, the CUI additionally controls block erasure

and word/byte write.
[A18-A0]
7FFFF
The Block Erase command requires appropriate command
data and an address within the block to be erased. The
Word/Byte Write command requires the command and
address of the location to be written.
Reserved for Future Implementation
The CUI does not occupy an addressable memory
location. It is written when WE# and CE# are active. The
address and data needed to execute a command are latched
on the rising edge of WE# or CE# (whichever goes high
first). Standard microprocessor write timings are used.

operations.

4.1 Read Array Command
4.4 Clear Status Register Command
Upon initial device power-up and after exit from deep
power-down mode, the device defaults to read array mode.
This operation is also initiated by writing the Read Array
command. The device remains enabled for reads until
another command is written. Once the internal WSM has
started a block erase or word/byte write, the device will
not recognize the Read Array command until the WSM
completes its operation unless the WSM is suspended via
an Erase Suspend or Word/Byte Write Suspend command.
The Read Array command functions independently of the
Status register bits SR.5, SR.4, SR.3 or SR.1 are set to
"1"s by the WSM and can only be reset by the Clear Status
Register command. These bits indicate various failure
conditions (see Table 7). By allowing system software to
reset these bits, several operations (such as cumulatively
erasing multiple blocks or writing several words/bytes in
sequence) may be performed. The status register may be
polled to determine if an error occurred during the
sequence.
To clear the status register, the Clear Status Register
command (50H) is written. It functions independently of
the applied V Voltage. RP# can be V or V . This

command is not functional during block erase or

The identifier code operation is initiated by writing the
Read Identifier Codes command. Following the command
write, read cycles from addresses shown in Figure 4
retrieve the manufacturer and device codes (see Table 5
for identifier code values). To terminate the operation,
write another valid command. Like the Read Array
command, the Read Identifier Codes command functions
independently of the V voltage and RP# can be V or
4.5 Block Erase Command
Erase is executed one block at a time and initiated by a
two-cycle command. A block erase setup is first written,
followed by an block erase confirm. This command
sequence requires appropriate sequencing and an address
within the block to be erased (erase changes all block data
to FFFFH). Block preconditioning, erase, and verify are
handled internally by the WSM (invisible to the system).
After the two-cycle block erase sequence is written, the
device automatically outputs status register data when read
(see Figure 5). The CPU can detect block erase completion
by analyzing the output data of the RY/BY# pin or status
register bit SR.7.

When the block erase is complete, status register bit SR.5
should be checked. If a block erase error is detected, the
status register should be cleared before system software
attempts corrective actions. The CUI remains in read
status register mode until a new command is issued.
4.3 Read Status Register Command
The status register may be read to determine when a block
erase or word/byte write is complete and whether the
operation completed successfully. It may be read at any
time by writing the Read Status Register command. After
writing this command, all subsequent read operations
output data from the status register until another valid
command is written. The status register contents are
latched on the falling edge of OE# or CE#, whichever
This two-step command sequence of set-up followed by
execution ensures that block contents are not accidentally
erased. An invalid Block Erase command sequence will
result in both status register bits SR.4 and SR.5 being set

4.6 Word/Byte Write Command
4.7 Block Erase Suspend Command
Word/byte write is executed by a two-cycle command
sequence. Word/byte write setup (standard 40H or
alternate 10H) is written, followed by a second write that
specifies the address and data (latched on the rising edge
of WE#). The WSM then takes over, controlling the
word/byte write and write verify algorithms internally.
After the word/byte write sequence is written, the device
automatically outputs status register data when read (see
Figure 6). The CPU can detect the completion of the
word/byte write event by analyzing the RY/BY# pin or
status register bit SR.7.
The Block Erase Suspend command allows block-erase
interruption to read or word/byte write data in another
block of memory. Once the block-erase process starts,
writing the Block Erase Suspend command requests that
the WSM suspend the block erase sequence at a
predetermined point in the algorithm. The device outputs
status register data when read after the Block Erase
Suspend command is written. Polling status register bits
SR.7 and SR.6 can determine when the block erase
operation has been suspended (both will be set to "1").
RY/BY# will also transition to High Z. Specification

WHRZ2
When word/byte write is complete, status register bit SR.4
should be checked. If word/byte write error is detected, the
status register should be cleared. The internal WSM verify
only detects errors for "1"s that do not successfully write
to "0"s. The CUI remains in read status register mode until
it receives another command.
At this point, a Read Array command can be written to
read data from blocks other than that which is suspended.
A Word/Byte Write command sequence can also be issued
during erase suspend to program data in other blocks.
Using the Word/Byte Write Suspend command (see
Section 4.8), a word/byte write operation can also be
suspended. During a word/byte write operation with block
erase suspended, status register bit SR.7 will return to "0"

4.8 Word/Byte Write Suspend Command
4.10 Block Locking
The Word/Byte Write Suspend command allows
word/byte write interruption to read data in other flash
memory locations. Once the word/byte write process
starts, writing the Word/Byte Write Suspend command
requests that the WSM suspend the word/byte write
sequence at a predetermined point in the algorithm. The
device continues to output status register data when read
after the Word/Byte Write Suspend command is written.

5 DESIGN CONSIDERATIONS
5.1 Three-Line Output Control
5.3 Power Supply Decoupling
Flash memory power switching characteristics require
careful device decoupling. System designers are interested
in three supply current issues; standby current levels,
active current levels and transient peaks produced by
falling and rising edges of CE# and OE#. Transient current
magnitudes depend on the device outputs’ capacitive and
inductive loading. Two-line control and proper decoupling
capacitor selection will suppress transient voltage peaks.
Each device should have a 0.1µF ceramic capacitor
connected between its V and GND and between its V
The device will often be used in large memory arrays.
SHARP provides three control inputs to accommodate
multiple memory connections. Three-line control provides
for:
a. Lowest possible memory power dissipation.
b. Complete assurance that data bus contention will not
occur.

and GND. These high-frequency, low inductance
capacitors should be placed as close as possible to package
leads. Additionally, for every eight devices, a 4.7µF
electrolytic capacitor should be placed at the array’s power
To use these control inputs efficiently, an address decoder
should enable CE# while OE# should be connected to all
memory devices and the system’s READ# control line.
This assures that only selected memory devices have
active outputs while deselected memory devices are in
standby mode. RP# should be connected to the system

5.7 Power Dissipation
When designing portable systems, designers must consider
battery power consumption not only during device
operation, but also for data retention during system idle
