SHARP’s LH28F160S3HT-LlOA Flash memory with Smart 3 technology is a high-density, low-cost, nonvolatile, *cad/write storage solution for a wide range of applications. Its symmetrically-blocked architecture, flexible voltage and extended cycling provide for highly flexible component suitable for resident flash arrays, SlMMs and memory :ards. 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 LH28F160S3HT-LlOA offers three levels of protection: absolute protection with V,, at ?ND, selective hardware block locking, or flexible software block locking. These alternatives give designers Jltimate control of their code security needs.
The LH28F160S3HT-LlOA is conformed to the flash Scalable Command Set (SCS) and the Common Flash
nterface (CFI) specification which enable universal and upgradable interface, enable the highest system/device
data transfer rates and minimize device and system-level implementation costs. The LH28F160S3HT-LlOA is manufactured on SHARP’s 0.35um
ndustry-standard package: the 56-Lead TSOP ideal for board constrained applications.

1 INTRODUCTION
This datasheet contains LH28F160S3HT-Ll OA specifications. Section 1 provides a flash memory overview. Sections 2, 3, 4, and 5 describe the memory organization and functionality. Section 6 covers electrical specifications.
1 .l Product Overview
The LH28F160S3HT-Ll OA is a high-performance
16M-bit Smart 3 Flash memory organized as 2MBx80MBxl6. The 2MB of data is arranged in thirty-two 64K-byte blocks which are individually erasable, lockable, and unlockable in-system. The
memory map is shown in Figure 3.
Smart 3’ technology provides a choice of V,, and V,, combinations, as shown in Table 1, to meet system performance and power expectations. 2.7V Vc, consumes approximately one-fifth the power of 5V Vc,. V,, at 2.7V, 3.3V and 5V eliminates the
need for a separate 12V converter, while V,,=5V
maximizes erase and write performance. In addition to flexible erase and program voltages, the dedicated
V,, pin gives complete data protection when

write suspend mode enables the system to read data or execute code from any other flash memory array
location. Individual block locking uses a combination of bits
and WP#, Thirty-two block lock-bits, to lock ant unlock blocks. Block lock-bits gate block erase, full
chip erase and (multi) word/byte write operations. Block lock-bit configuration operations (Set Block Lock-Bit and Clear Block Lock-Bits commands) sei and cleared block lock-bits.
The status register indicates when the WSM’s block erase, full chip erase, (multi) word/byte write or block lock-bit configuration operation is finished.
The STS output gives an additional indicator of WSM activity by providing both a hardware signal of status (versus software polling) and status maskins (interrupt masking for background block erase, fol example). Status polling using STS minimizes bott CPU overhead and system power consumption. STS pin can be configured to different states using the Configuration command. The STS pin defaults tc
RY/BY# operation. When low, STS indicates that the
WSM is performing a block erase, full chip erase
(multi) word/byte write or block lock-bit configuration STS-High Z indicates that the WSM is ready for a
new command, block erase is suspended and (multi: word/byte write are inactive, (multi) word/byte write are suspended, or the device is in deep power-dowr
mode. The other 3 alternate configurations are al
pulse mode for use as a system interrupt. The access time is 100ns (tAVQv) over the extendec
temperature range (-40°C to +85”C) and Vc, suppI\ voltage range of 3.OV-3.6V. At lower V,, voltage, the access time is 120ns (2.7V-3.6V).
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, full chip erase, (multi) word/byte write and block lock-bit configuration operations.
4 block erase operation erases one of the device’s %lK-byte blocks typically within 0.41s (3.3V Vcc, 5V VP,) independent of other blocks. Each block can be independently erased 100,000 times (3.2 million olock erases per device). Block erase suspend mode allows system software to suspend block erase to read or write data from any other block.
A word/byte write is performed in byte increments typically within 12.95ps (3.3V V,,, 5V VP,). A multi word/byte write has high speed write performance of
2.7@byte (3.3V V,,, 5V VP,). (Multi) Word/byte
The Automatic Power Savings (APS) feature
substantially reduces active current when the device is in static mode (addresses not switching). In APS m‘ode, the typical I,,, current is 3 mA at 3.3V V,c.
When either CE,# or CE,#, and RP# pins are at V,, the I,, CMOS standby mode is enabled. When the RP# pin is at GND, deep power-down mode ic enabled which minimizes power consumption and provides write protection during reset. A reset time (tPHav) 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 device is available in 56-Lead TSOP (Thin Small Outline Package, 1.2 mm thick). Pinout is shown in Figure 2.

2 PRINCIPLES OF OPERATION
The LH28F160S3HT-Ll OA Flash memory includes an on-chip WSM to manage block erase, full chip erase, (multi) word/byte write and block lock-bit configuration functions. It allows for: 100% TTL-level control inputs, fixed power supplies during block erase, full chip erase, (multi) word/byte write and block lock-bit configuration, and minimal processor overhead with RAM-Like interface timings.
After initial device power-up or return from deep power-down mode (see Bus Operations), the device defaults to read array mode. Manipulation of external memory control pins allow array read, standby, and output disable operations.
Status :egister, query structure and identifier codes can be accessed through the CUI independent of the V,, voltage. High voltage on VPP enables successful block erase, full chip erase, (multi) word/byte write and block lock-bit configuration. All functions
associated with altering memory contents-block erase, full chip erase, (multi) word/byte write and block lock-bit configuration, status, query and identifier codes-are accessed via the CUI and
verified through the status register.
Commands are microprocessor write timings. The CUI contents serve as input to the WSM, which controls the block erase, full chip erase, (multi) word/byte write and block lock­bit configuration. The internal algorithms are regulated by the WSM, including pulse repetition, internal verification, Addresses and data are internally latch during write cycles. Writing the appropriate command outputs array data, accesses the identifier codes, outputs query structure or outputs status register data.
Interface software that initiates and polls progress of block erase, full chip erase, (multi) word/byte write and block lock-bit configuration 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 or write data from any other block. Write suspend allows system software to suspend a (multi) word/byte write to read data from any other flash memory array location.

2.1 Data Protection
Depending on the application, the system designer may choose to make the V,, power supply switchable (available only when block erase, full chip erase, (multi) word/byte write and block lock-bit configuration are required) or hardwired to VPPH1,2/3. The device accommodates either design practice and encourages optimization of the processor-memory interface.
When Vpp~VppLKt
altered. The CUI, with multi-step block erase, full chip erase, (multi) word/byte write and block lock-bit configuration command sequences, provides protection from unwanted operations even when high
voltage,is applied to V,,. All write functions are disabled when Vcc is below the write lockout voltage V,,, or when RP# is at V,,. The device’s block
locking capability provides additional protection from inadvertent code or data alteration by gating block
erase, full chip erase and (multi) word/byte write operations.
memory contents cannot be
3 BUS OPERATION
The local CPU reads and writes flash memory in­system. All bus cycles to or from the flash memory conform to standard microprocessor bus cycles.
3.1 Read
Information can be read from any block, identifier codes, query structure,‘or status register independent
of the V,, voltage. RP# must be at VI,. The first task is to write the appropriate read mode
command (Read Array, Read Identifier Codes, Query 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. Five control pins dictate the data flow in and out of the component: CE# (CE,#, CE,#), OE#, WE#, RP# and WP#. CE,#, CE,# and OE# must be driven active to obtain data at the outputs. CE,#, CE,# is the device selection control, and when active enables the selected memory device. OE# is the data output (DC&-DQ,,) control and when active drives the selected memory data onto the I/O bus. WE# and RP# must be at V,,. Figure 17, 18 illustrates a read cycle.
7
3.2 Output Disable
With OE# at a logic-high level (VI,), the devict outputs are disabled. Output pins DO,-DQ,, an
placed in a high-impedance state.
3.3 Standby
Either CE,# or CE,# at a logic-high level (V,,) place:
the device in standby mode which substantiall!
reduces device power consumption. DQo-DQ,, outputs are placed in a high-impedance statt independent of OE#. If deselected during bloc1 erase, full chip erase, (multi) word/byte write ant block lock-bit configuration, the device continue: functioning, and consuming active power until the operation completes.
3.4 Deep Power-Down
RP# at V,, initiates the deep power-down mode. In read modes, RP#-low deselects the memory
places output drivers in a high-impedance state ant
turns off all internal circuits. RP# must be held low fol a minimum of 100 ns. Time t,,crv is required after
return from power-down until initial memory access
outputs are valid. After this wakeup interval, norma operation is restored. The CUI is reset to read arra) mode and status register is set to 80H.
During block erase, full chip erase, (multi) word/byte write or block lock-bit configuration modes, RP#-low will abort the operation. STS remains low until the
reset operation is complete. Memory contents being altered are no longer valid; the data may be partially erased or written. Time tPHWL is required after RP# goes to logic-high (V,,) before another command can
be written. As with any automated device, it is important tc
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, full chip erase, (multi) word/byte write and block lock-bit configuration. 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
The read identifier codes operation outputs the manufacturer code, device code, block status codes for each block (see Figure 4). Using the manufacturer and device codes, the system CPU can automatically match the device with its proper algorithms. The block status codes identify locked or unlocked block setting and erase completed or erase uncompleted condition.

write and block lock-bit configuration.
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.
Set Block Lock-Bit command requires the command
and block address within the device (Block Lock) to
be locked. The Clear Block Lock-Bits command
requires the command and address within the device.
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. Figures 19 and 20 illustrate WE# and CE#-controlled write operations.
4 COMMAND DEFINITIONS
When the V,, voltage I V,,,,, Read operations from the status register, identifier codes, query, or blocks
are enabled. Placing V,,,,,us on V,, enables
successful block erase, full chip erase, (multi)
word/byte write and block lock-bit configuration
operations.
Device operations are selected by writing specific
commands into the CUI. Table 4 defines these
commands.

4.1 Read Array Command 4.3 Read 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, full chip erase, (multi) word/byte write or block lock-bit configuration, the device will not recognize the Read Array command until the WSM completes its operation unless the WSM is suspended via an Erase Suspend and (Multi) Word/byte Write Suspend command. The Read Array command functions independently of the VP,, voltage and RP# must be
Vi,*
The
status
register may be read to determine when i block erase, full chip erase, (multi) word/byte write OI block lock-bit configuration is complete and whethei the operation completed successfully(see Table 14)
It may be read at any time by writing the Read Statu:
Register command. After writing this command, al subsequent read operations output data from the status register until another valid command is written The status register contents are latched on the fallins edge of OE# or CE#(Either CE,# or CE,#) whichever occurs. OE# or CE#(Either CE,# or CE,#: must toggle to ‘Jr, before further reads to update the status register latch. The Read Status Register command functions independently of the V,, voltage
RP# must be VI,.
4.2 F&ad Identifier Codes Command
The extended status register may be read tc
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, device, block lock configuration and block erase status (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# must be V,,. Following the Read Identifier Codes command, the following information can be read:

determine multi word/byte write availability(see Table
14.1). The extended status register may be read a any time by writing the Multi Word/Byte Write command. After writing this command, all subsequen read operations output data from the extended statuz register, until another valid command is written. Mult Word/Byte Write command must be re-issued tc update the extended status register latch.
4.4 Clear Status Register Command
Status register bits SR.5, SR.4, SR.3 and SR.l 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 14). By allowins
system software to reset these bits, severa operations (such as cumulatively erasing or lockinc multiple blocks or writing several bytes in sequence: may be performed. The status register may be pollee
to determine if an error occurs 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# must be VI,. This command is not functional during block erase, ful chip erase, (multi) word/byte write block lock-bii configuration, block erase suspend or (multi: word/byte write suspend modes.

1.5 Query Command
=luery database can be read by writing Query :ommand (98H). Following the command write, read
ycle from address shown in Table 7-l 1 retrieve the xitical information to write, erase and otherwise :ontrol the flash component. A, of query offset address is ignored when X8 mode (BYTE#=V,L).
;luery data are always presented on the low-byte jata output (DC&-D&). In x16 mode, high-byte ;DQs-DQ,s) outputs OOH. The bytes not assigned to any information or reserved for future use are set to ‘0”. This command functions independently of the Jpp voltage. RP# must be V,,.
