2 PRINCIPLES &OPERATION
The LH28F160S5T-L70A Flash memory includes an on-chip WSM to manage block erase, full chip erase, write and block lock-bit (multi) word/byte 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 bgister, query structure and identifier codes can be accessed through the CUI independent of the VP, voltage. High voltage on VP, 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. written standard Commands are using 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, and mar ining of data. internal verification, atch during write Addresses and data are internally 91 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 *cad or write data from any other block. Write suspend allows system software to suspend a (multi) Nerd/byte write to read data from any other flash nemory 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 V,,,,. The device accommodates either design practice and encourages optimization of the processor-memory interface. contents cannot be altered. The CUI, with multi-step block erase, full chip erase, (multi) word/byte write and block lock-bit sequences, provides configuration command protection from unwanted operations even when high voltage ,is applied to V,,. All write functions are disabled when V,, is below the write lockout voltage VLKO or when RP# is at V,,. The devices 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.

With OE# at a logic-high level (VI,), the device outputs are disabled. Output pins DQo-DQ,, are 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 substantial! reduces device power consumption. DQo-DQ, outputs are placed in a high-impedance state independent of OE#. If deselected during bloc1 erase, full chip erase, (multi) word/byte write am block lock-bit configuration, the device continue: functioning, and consuming active power until the operation completes.

When Vpp~VppLK,memory

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 fo a minimum of 100 ns. Time tpHQv is required afte, return from power-down until initial memory access outputs are valid. After this wake-up 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#-Ion will abort the operation. STS remains low until the reset operation is complete. Memory contents beins altered are no longer valid; the data may be partialI] erased or written. Time t,,,, is required after RP#I goes to logic-high (V,,) before another command car be written. As with any automated device, it is important tc a$sert 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-bii 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. SHARPs 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 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;gr status register independent of the V,, voltyge. RP# must be at V,,. 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# (CEo#, CE,#), OE#, WE#, RP# and WP#. CE,#, CE,# and OE# must be driven active to obtain data at the outputs. CE,#, CE,# is ihe device selection control, and when active enables the selected memory device. OE# is the data output (DQo-DQ,,) control and when active drives the selected memory data onto the I/O bus. WE# and SP# must be at VI,. Figure 17, 18 illustrates a read :ycle.

LHF16KA9 4.3 Read Status Register Command

4.1 Read Array 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 V,, voltage and RP# must be

.4.12 Set Block Lock-Bit Command
A flexible block locking and unlocking scheme is enabled via block lock-bits. The block lock-bits gate program and erase operations With WP#=V,,, individual block lock-bits can be set using the Set Block Lock-Bit command. See Table 13 for a summary of hardware and software write protection options. Set block lock-bit is executed by a two-cycle command sequence. The set block lock-bit setup along with appropriate block or device address is written followed by either the set block lock-bit confirm (and an address within the block to be locked). The WSM then controls the set block lock-bit algorithp. After the sequence is written, the device automatically outputs status register data when read (see Figure 12). The CPU can detect the completion of the set block lock-bit event by analyzing the STS pin output or status register bit SR.7. When the set block lock-bit operation is complete, status register bit SR.4 should be checked. If an error is detected, the status register should be cleared. The CUI will remain in read status register mode until a new command is issued. This two-step sequence of set-up followed by execution ensures that block lock-bits are not accidentally set. An invalid Set Block Lock-Bit command will result in status register bits SR.4 and SR.5 being set to 1. Also, reliable operations occur only when Vcc=Vccv2 and VPP=VPPHI. In the absence of this high voltage, block* lock-bit contents are protected against alteration. A successful set block lock-bit operation requires WP#=V,,. If it is attempted with WP#=V,,, SR.l and SR.4 will be set to 1 and the operation will fail. Set block lock-bit operations with WP#<V,, produce spurious results and should not be attempted.
block lock-bits can be cleared using only the Cleal Block Lock-Bits command. See Table 13 for s summary of hardware and software write protectior options. Clear block lock-bits operation is executed by a two. cycle command sequence. A clear block lock-bits setup is first written. After the command is written, the device automatically outputs status register data when read (see Figure 13). The CPU can deteci completion of the clear block lock-bits event by analyzing the STS Pin output or status register bii SR.7. When the operation is complete, status register bii SR.5 should be checked. If a clear block lock-bit error is detected, the status register should be cleared. The CUI will remain in read status register mode until another command is issued. This two-step sequence of set-up followed by execution ensures that block lock-bits are not accidentally cleared. An invalid Clear Block Lock-Bits command sequence will result in status register bits SR.4 and SR.5 being set to 1. Also, a reliable clear block lock-bits operation can only occur when Vcc=Vcc1,2 and VPP=VPPH1. If a clear block lock-bits operation is attempted while V,,IV,,,k, SR.3 and SR.5 will be set to 1 I. In the absence of this high voltage, the block lock-bits content are protected against alteration. A successful clear block lock-bits operation requires WP#=V,,. If it is attempted with WP#=V,,, SR.l and SR.5 will be set to 1 and the operation will fail. Clear block lock-bits operations with V,,,<RP# produce spurious results and should not be attempted. If a clear block lock-bits operation is aborted due to V,, or Voo transitioning out of valid range or RP# active transition, block lock-bit values are left in an undetermined state. A repeat of clear block lock-bits is required to initialize block lock-bit contents to known values.

5 DESIGN CONSIDERATIONS 5.1 Three-Line Output Control
The device will often be used in large memory arrays. inputs to SHARP provides three control accommodate multiple memory connections. ThreeLine control provides for: a. Lowest possible memory power dissipation. b. Complete assurance that data bus contention will not occur. To use these control inputs efficiently, an address decoder should enable CE# while OE# should be connected to all memory devices and the systems READ#Qontrol 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 POWERGOOD signal to prevent unintended writes during system power transitions. POWERGOOD should also toggle during system reset.
STS, in default mode, is also High Z when the device is in block erase suspend (with (multi) word/byte write inactive), (multi) word/byte write suspend or deep power-down modes.
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 O.luF ceramic capacitor connected between its Vcc and GND and between its V,, and GND. These high-frequency, low inductance capacitors should be placed as close as possible to package leads. Additionally, for every eight devices, a 4.7uF electrolytic capacitor should be placed at the arrays power supply connection between Vcc and GND. The bulk capacitor will overcome voltage slumps caused by PC board trace inductance.

5.2 STS and Block Erase, Full Chip Erase, (Multi) Word/Byte Write and Block Lock-Bit Configuration Polling
STS is an open drain output that should be connected to Vcc b y a pullup resistor to provide a hardware method of detecting block erase, full chip erase, (multi).word/byte write and block lock-bit configuration completion. In default mode, it transitions low after block erase,, full chip erase, (multi) word/byte write or block lock-bit configuration commands and returns to V,, when the WSM has finished executing the internal algorithm. For alternate STS pin configurations, see the Configuration command. STS can be connected to an interrupt input of the system CPU or controller. It is active at all times.
5.4 Vpp Trace on Printed Circuit Boards
Updating flash memories that reside in the target system requires that the printed circuit board designer pay attention to the V,, Power supply trace. The V,, pin supplies the memory cell current for block erase, full chip erase, (multi) word/byte write and block lock-bit configuration. Use similar trace widths and layout considerations given to the V,, power bus. Adequate V,, supply traces and decoupling will decrease V,, voltage spikes and overshoots.
5.5 VCC, Vpp, RP# Transitions
Block erase, full chip erase, (multi) word/byte write and block lock-bit configuration are not guaranteed if V,, falls outside of a valid V,,,, range, Voo falls outside of a valid VCCIR range, or RP#=V,,. If V,,X error is detected, status register bit SR.3 is set to 1 along with SR.4 or SR.5, depending on the attempted operation. If RP# transitions to V,, during block erase, full chip erase, (multi) word/byte write or block lock-bit configuration, STS(if set to RY/BY# mode) will remain low until the reset operation is complete. Then, the operation will abort and the device will enter deep power-down. The aborted operation may leave data partially altered. Therefore, the command sequence must be repeated after normal operation is restored. Device power-off or RP# transitions to V,, clear the status register. The CUI latches commands issued by system software and is not altered by V,, or CE# transitions or WSM actions. Its state is read array mode upon power-up, after exit from deep power-down or after Voc transitions below VLko. After block erase, full chip erase, (multi) word/byte write or block lock-bit configuration, even after V,, transitions down to V,,,,, the CUI must be placed in read array mode via the Read Array command if subsequent access to the memory array is desired.

powers-up first. Internal circuitry resets the CUI tc read array mode at power-up. A system designer must guard against spuriou: writes for Voo voltages above VLKo when V,, i! active. Since both WE# and CE# must be low for : command write, driving either to V,, will inhibit writes The CUls two-step command sequence architecturt provides added level of protection against dat: alteration. In-system block lock and unlock capability prevent: inadvertent data alteration. The device is disablec while RP#=VIL regardless of its control inputs state.

5.7 Power Dissipation

When designing portable systems, designers mus consider battery power consumption not only durin! device operation, but also for data retention durin! system idle time. Flash memorys nonvolatiliQ increases usable battery life because data is retainec when system power is removed. In addition, deep power-down mode ensure: extremely low power consumption even when systen power is applied. For example, portable computin{ products and other power sensitive applications tha use an array of devices for solid-state storage car consume negligible power by lowering RP# to V,, standby or sleep modes. If access is again needed the devices can be read following the tPHQV ant t,,,, wake-up cycles required after RP# is firs raised to V,,. See AC CharacteristicsRead OnI) and Write Operations and Figures 17, 18, 19, 20 foi more information.
