INPUT/
OUTPUT
DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User
Interface) write cycles, outputs data during memory array, status register, query code and
identifier code reads. Data pins float to high-impedance (High Z) when the chip or
outputs are deselected. Data is internally latched during an erase or program cycle.
CE#
INPUT
CHIP ENABLE: Activates the device’s control logic, input buffers, decoders and sense
amplifiers. CE#-high (VIH) deselects the device and reduces power consumption to
standby levels.
RST#
INPUT
RESET: When low (VIL), RST# resets internal automation and inhibits write operations
which provides data protection. RST#-high (VIH) enables normal operation. After
power-up or reset mode, the device is automatically set to read array mode. RST# must
be low during power-up/down.
OE#
INPUT
OUTPUT ENABLE: Gates the device’s outputs during a read cycle.
INPUT
WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are
latched on the rising edge of CE# or WE# (whichever goes high first).
INPUT/
SUPPLY
WRITE PROTECT: When WP#/ACC is VIL, locked-down blocks cannot be unlocked.
Erase or program operation can be executed to the blocks which are not locked and not
locked-down. When WP#/ACC is VIH, lock-down is disabled.
Applying 9.5V±0.5V to WP#/ACC provides fast erasing or fast programming mode. In
this mode, WP#/ACC is power supply pin. Applying 9.5V±0.5V to WP#/ACC during
erase/program can only be done for a maximum of 1,000 cycles on each block. WP#/
ACC may be connected to 9.5V±0.5V for a total of 80 hours maximum. Use of this pin
at 9.5V+0.5V beyond these limits may reduce block cycling capability or cause
permanent damage.
WE#
WP#/ACC
RY/BY#
Name and Function
ADDRESS INPUTS: Inputs for addresses.
READY/BUSY#: Indicates the status of the internal WSM (Write State Machine). When
low, WSM is performing an internal operation (block erase, full chip erase, (page buffer)
OPEN DRAIN
program or OTP program). RY/BY#-High Z indicates that the WSM is ready for new
OUTPUT
commands, block erase is suspended and (page buffer) program is inactive, (page buffer)
program is suspended, or the device is in reset mode.
VCC
SUPPLY
DEVICE POWER SUPPLY (2.7V-3.3V): With VCC≤VLKO, all write attempts to the
flash memory are inhibited. Device operations at invalid VCC voltage (see DC
Characteristics) produce spurious results and should not be attempted.
VCCQ
SUPPLY
INPUT/OUTPUT POWER SUPPLY (2.7V-3.3V): Power supply for all input/output
pins.
GND
SUPPLY
GROUND: Do not float any ground pins.
NC
NO CONNECT: Lead is not internally connected; it may be driven or floated.

NOTES:
1. "X" denotes the operation available.
2. Dual Work Restrictions:
Status register reflects WSM (Write State Machine) state.
Only one plane can be erased or programmed at a time - no command queuing.
Commands must be written to an address within the block targeted by that command.

2. X can be VIL or VIH for control pins and addresses.
3. RST# at GND±0.2V ensures the lowest power consumption.
4. Command writes involving block erase, full chip erase, (page buffer) program or OTP program are reliably
executed when VCC=2.7V-3.3V.
5. Refer to Table 5 for valid DIN during a write operation.
6. Never hold OE# low and WE# low at the same timing.
7. Query code = Common Flash Interface (CFI) code.
8. RY/BY# is VOL when the WSM (Write State Machine) is executing internal block erase, full chip erase,
(page buffer) program or OTP program algorithms. It is High Z during when the WSM is not busy, in
block erase suspend mode (with program and page buffer program inactive), (page buffer) program suspend
mode, or reset mode.

NOTES:
1. Bus operations are defined in Table 4.
2. All addresses which are written at the first bus cycle should be the same as the addresses which are written at the second
bus cycle.
X=Any valid address within the device.
PA=Address within the selected plane.
IA=Identifier codes address (See Table 3).
QA=Query codes address. Refer to Appendix of LH28F128BF series for details.
BA=Address within the block being erased, set/cleared block lock bit or set block lock-down bit.
WA=Address of memory location for the Program command or the first address for the Page Buffer Program command.
OA=Address of OTP block to be read or programmed (See Figure 3).
3. ID=Data read from identifier codes. (See Table 3).
QD=Data read from query database. Refer to Appendix of LH28F128BF series for details.
SRD=Data read from status register. See Table 9.1, Table 9.2 for a description of the status register bits.
WD=Data to be programmed at location WA. Data is latched on the rising edge of WE# or CE# (whichever
goes high first) during command write cycles.
OD=Data within OTP block. Data is latched on the rising edge of WE# or CE# (whichever goes high first)
during command write cycles.
N-1=N is the number of the words to be loaded into a page buffer.
4. Following the Read Identifier Codes/OTP command, read operations access manufacturer code, device code, block lock
configuration code and the data within OTP block (See Table 3).
The Read Query command is available for reading CFI (Common Flash Interface) information.
5. Block erase, full chip erase or (page buffer) program cannot be executed when the selected block is locked. Unlocked
block can be erased or programmed when RST# is VIH.
6. Either 40H or 10H are recognized by the CUI (Command User Interface) as the program setup.

7. Following the third bus cycle, input the program sequential address and write data of "N" times. Finally, input the any
valid address within the target block to be programmed and the confirm command (D0H).
8. If the program operation in one plane is suspended and the erase operation in other plane is also suspended, the suspended
program operation will be resumed first.
9. Full chip erase and OTP program operations can not be suspended. The OTP Program command can not be accepted
while the block erase operation is being suspended.
10. Following the Clear Block Lock Bit command, block which is not locked-down is unlocked when WP#/ACC is VIL.
When WP#/ACC is VIH, lock-down bit is disabled and the selected block is unlocked regardless of lock-down
configuration.
11. Commands other than those shown above are reserved by SHARP for future device implementations and should not be
used.

NOTES:
1. DQ0=1: a block is locked; DQ0=0: a block is unlocked.
DQ1=1: a block is locked-down; DQ1=0: a block is not locked-down.
2. Erase and program are general terms, respectively, to express: block erase, full chip erase and
(page buffer) program operations.
3. At power-up or device reset, all blocks default to locked state and are not locked-down, that is,
[001] (WP#/ACC=0) or [101] (WP#/ACC=1), regardless of the states before power-off or reset
operation.
4. When WP#/ACC is driven to VIL in [110] state, the state changes to [011] and the blocks are
automatically locked.
5. OTP (One Time Program) block has the lock function which is different from those described
above.

NOTES:
1. "Set Lock" means Set Block Lock Bit command, "Clear Lock" means Clear Block Lock Bit
command and "Set Lock-down" means Set Block Lock-Down Bit command.
2. When the Set Block Lock-Down Bit command is written to the unlocked block (DQ0=0), the
corresponding block is locked-down and automatically locked at the same time.
3. "No Change" means that the state remains unchanged after the command written.
4. In this state transitions table, assumes that WP#/ACC is not changed and fixed VIL or VIH.

NOTES:
1. "WP#/ACC=0→1" means that WP#/ACC is driven to VIH and "WP#/ACC=1→0" means that
WP#/ACC is driven to VIL.
2. State transition from the current state [011] to the next state depends on the previous state.
3. When WP#/ACC is driven to VIL in [110] state, the state changes to [011] and the blocks are
automatically locked.
4. In this state transitions table, assumes that lock configuration commands are not written in
previous, current and next state.
