ETOXTM* Flash Technology
Not designed or rated as radiation hardened
The product, which is Page Mode Flash memory, is a low power, 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. Its low voltage operation capability
greatly extends battery life for portable applications.
The product provides high performance asynchronous page mode. It allows code execution directly from Flash, thus
eliminating time consuming wait states.
The memory array block architecture utilizes Enhanced Data Protection features, and provides separate Parameter and Main
Blocks that provide maximum flexibility for safe nonvolatile code and data storage.
Fast program capability is provided through the use of high speed Page Buffer Program.
Special OTP (One Time Program) block provides an area to store permanent code such as a unique number.

Table 1. Pin Descriptions
Symbol Type Name and Function
A0-A20 INPUT ADDRESS INPUTS: Inputs for addresses. 32M: A0-A20
DQ0-DQ15 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.
WE# 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).
VCC SUPPLY
DEVICE POWER SUPPLY (2.7V-3.6V): With VCCVLKO, 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.
GND SUPPLY GROUND: Do not float any ground pins.
NC NO CONNECT: Lead is not internally connected; it may be driven or floated.

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 2).
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

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,
[01] regardless of the states before power-off or reset operation.
4. 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.

AC test inputs are driven at VCC(min) for a Logic "1" and 0.0V for a Logic "0".
Input timing begins, and output timing ends at VCC/2. Input rise and fall times (10% to 90%) < 5ns.

1.2.3 DC Characteristics
NOTES:
1. All currents are in RMS unless otherwise noted. Typical values are the reference values at VCC=3.0V and TA=+25°C
unless VCC is specified.
2. ICCWS and ICCES are specified with the device de-selected. If read or (page buffer) program while in block erase suspend
mode, the device’s current draw is the sum of ICCWS or ICCES and ICCR or ICCW
, respectively.
3. Block erase, full chip erase, (page buffer) program and OTP program are inhibited when VCCVLKO, and not guaranteed
outside the specified voltage.
4. The Automatic Power Savings (APS) feature automatically places the device in power save mode after read cycle
completion. Standard address access timings (tAVQV) provide new data when addresses are changed.

1.2.5 AC Characteristics - Write Operations(1), (2)
NOTES:
1. The timing characteristics for reading the status register during block erase, full chip erase, (page buffer) program and
OTP program operations are the same as during read-only operations. Refer to AC Characteristics for read-only
operations.
2. A write operation can be initiated and terminated with either CE# or WE#.
3. Sampled, not 100% tested.
4. Write pulse width (tWP) is defined from the falling edge of CE# or WE# (whichever goes low last) to the rising edge of
CE# or WE# (whichever goes high first). Hence, tWP=tWLWH=tELEH=tWLEH=tELWH.
5. Write pulse width high (tWPH) is defined from the rising edge of CE# or WE# (whichever goes high first) to the falling
edge of CE# or WE# (whichever goes low last). Hence, tWPH=tWHWL=tEHEL=tWHEL=tEHWL.
6. tWHR0 (tEHR0) after the Read Query or Read Identifier Codes/OTP command=tAVQV+100ns.
7. Refer to Table 4 for valid address and data for block erase, full chip erase, (page buffer) program, OTP program or lock bit
configuration.
