ETOXTM* Flash Technology
Not designed or rated as radiation hardened
The product, which is Page Mode Flash memory, is a high density, low cost, nonvolatile read/write storage solution for a
wide range of applications. The product can operate at VCC=2.7V-3.6V and VPEN=2.7V-3.6V
The product supports high performance page mode. It allows code execution directly from Flash, thus eliminating time
consuming wait states.
Fast program capability is provided through the use of high speed Page Buffer Program.
The block locking scheme is available for memory array and this scheme provides maximum flexibility for safe nonvolatile
code and data storage.
OTP (One Time Program) block provides an area to store security code and to protect its code.

Table 1. Pin Descriptions
Symbol
Type
Name and Function
A0
INPUT
ADDRESS INPUTS: Lowest address input in byte mode (BYTE#=VIL : ×8 bit).
Address is internally latched during an erase or a program cycle. This pin is not used in
word mode (BYTE#=VIH : ×16 bit)
A22-A1
INPUT
ADDRESS INPUTS: Inputs for addresses during read, erase and program operations.
Addresses are internally latched during an erase or a program cycle.
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,
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.
DQ15-DQ8 pins are not used in byte mode (BYTE#=VIL : ×8 bit).
INPUT
CHIP ENABLE: Activates the device’s control logic, input buffers, decoders and sense
amplifiers. When the device is de-selected, power consumption reduces to standby
levels. Refer to Table 2 to determine whether the device is selected or de-selected
depending on the state of CE0, CE1 and CE2.
RP#
INPUT
RESET: When low (VIL), RP# resets internal automation and inhibits erase and program
operations, which provides data protection. RP#-high (VIH) enables normal operation.
After power-up or reset mode, the device is automatically set to read array mode.
RP# must be low during power-up/down.
OE#
INPUT
OUTPUT ENABLE: Gates the device’s outputs during a read cycle.
WE#
INPUT
WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are
latched on the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of
WE# (whichever occurs first).
DQ15-DQ0
CE0,
CE1,
CE2
STS
STATUS: Indicates the status of the internal WSM (Write State Machine). When
configured in level mode (default mode), STS acts as a RY/BY# pin (STS is VOL when
OPEN DRAIN
the WSM is executing internal erase or program algorithms). When configured in one of
OUTPUT
its pulse modes, STS can pulse to indicate erase/program completion. Refer to Table 9
for STS configuration.
BYTE#
INPUT
BYTE ENABLE: BYTE# VIL places the device in byte mode (×8). In this mode, DQ15DQ8 is floated (High Z) and A0 is the lowest address input. BYTE# VIH places the
device in word mode (×16) and A1 is the lowest address input.
VPEN
INPUT
MONITORING POWER SUPPLY VOLTAGE: VPEN is not used for power supply pin.
With VPEN≤VPENLK, block erase, (page buffer) program, block lock configuration and
OTP program cannot be executed and should not be attempted.
VCC
SUPPLY
DEVICE POWER SUPPLY (2.7V-3.6V): With VCC≤VLKO, all write attempts to the
flash memory are inhibited. Device operations at invalid VCC voltage (refer to DC
Characteristics) produce spurious results and should not be attempted.
VCCQ
SUPPLY
INPUT/OUTPUT POWER SUPPLY (2.7V-3.6V): Power supply for all input/output
pins.
GND
SUPPLY
NC
GROUND: Do not float any ground pins.
NO CONNECT: Lead is not internally connected; it may be driven or floated.

NOTES:
1. Refer to DC Characteristics. When VPEN≤VPENLK, memory contents can be read, but cannot be altered.
2. X can be VIL or VIH for control pins and addresses, and VPENLK or VPENH for VPEN.
Refer to DC Characteristics for VPENLK and VPENH voltages.
3. Refer to Table 2 to determine whether the device is selected or de-selected depending on the state of CE0, CE1 and CE2.
4. DQ refers to DQ15-DQ0 in word mode (BYTE#=VIH : ×16 bit) and DQ7-DQ0 in byte mode (BYTE#=VIL : ×8 bit).
5. RP# at GND±0.2V ensures the lowest power consumption.
6. Command writes involving block erase, (page buffer) program, block lock configuration or OTP program are reliably
executed when VPEN=VPENH and VCC=2.7V-3.6V.
7. Refer to Table 5 for valid DIN during a write operation.
8. Never hold OE# low and WE# low at the same timing.
9. Refer to Appendix of LH28F640SP series for more information about query code.
10. STS is VOL when the WSM (Write State Machine) is executing internal block 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.

ID=Data to be read from identifier codes. (Refer to Table 3).
QD=Data to be read from query database. Refer to Appendix of LH28F640SP series for details.
SRD=Data to be read from status register. Refer to Table 7 for a description of the status register bits.
WD=Data to be programmed at location WA. Data is latched on the first edge of CE0, CE1 or CE2 that disables
the device or the rising edge of WE# (whichever occurs first) during command write cycles.
N-1=N is the number of the words /bytes to be loaded into a page buffer.
OD=Data within OTP block. Data is latched on the first edge of CE0, CE1 or CE2 that disables
the device or the rising edge of WE# (whichever occurs first) during command write cycles.
CC= STS configuration code (Refer to Table 9).
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 (Refer to Table 3).
The Read Query command is available for reading CFI (Common Flash Interface) information.
5. Block erase or (page buffer) program cannot be executed when the selected block is locked. Unlocked block can be erased
or programmed when RP# 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, write the program sequential address and data of "N" times. Finally, write the any valid
address within the block to be programmed and the confirm command (D0H).

Refer to Appendix of LH28F640SP series for details.
8. If both block erase operation and (page buffer) program operation are suspended, the suspended (page buffer) program
operation is resumed when writing the Block Erase and (Page Buffer) Program Resume (D0H) command.
9. Following the Clear Block Lock Bits command, all the blocks are unlocked at a time.
10. Commands other than those shown above are reserved by SHARP for future device implementations and should not be
used.

NOTES:
1. Selected block is locked by the Set Block Lock Bit command. Following the Clear Block
Lock Bits command, all the blocks are unlocked at a time.
2. Locked and unlocked states remain unchanged even after power-up/down and device reset.
3. After writing the Read Identifier Codes/OTP command, read operation outputs the block lock bit
status on DQ0 (refer to Table 3).
4. Erase and program are general terms, respectively, to express: block erase and
(page buffer) program operations.

After power-up or device reset, STS configuration is set to

DQ1-DQ0 = STS CONFIGURATION CODE (CC)
00 = level mode: RY/BY# indication. (Default)
01 = pulse mode on erase complete.
10 = pulse mode on program complete.

STS configuration 00
The output of the STS pin is the control signal to prevent
accessing a flash memory while the internal WSM is busy
(SR.7="0").
In STS configuration = "00", STS is VOL when the WSM is STS configuration 01
The output of the STS pin is the control signal to indicate
executing internal erase or program algorithms.
that the erase operation is completed and the flash memory
is available for the next operation.
STS configuration codes "01", "10" and "11" are all pulse
modes such that the STS pin pulses low then high when the
operation indicated by the configuration code is completed. STS configuration 10
The output of the STS pin is the control signal to indicate
that the program operation is completed and the flash
memory is available for the next operation.
STS configuration 11
The output of the STS pin is the control signal to indicate
that the erase or program operation is completed and the
flash memory is available for the next operation.
NOTE:
1. When the device is configured in one of the pulse modes, the STS pin pulses low with a typical pulse width of 250ns.
