Functional Overview
This section provides an overview of the features and capabilities of the Intel
StrataFlash® Embedded Memory P33 device.
The Intel® P33 device provides density upgrades from 64-Mbit through 512-Mbit. This
family of devices provides high performance at low voltage on a 16-bit data bus.
Individually erasable memory blocks are sized for optimum code and data storage.
Upon initial power up or return from reset, the device defaults to asynchronous page-
mode read. Configuring the RCR enables synchronous burst-mode reads. In
synchronous burst mode, output data is synchronized with a user-supplied clock signal.
A WAIT signal provides an easy CPU-to-flash memory synchronization.
In addition to the enhanced architecture and interface, the device incorporates
technology that enables fast factory program and erase operations. Designed for low-
voltage systems, the Intel® P33 device supports read operations with VCC at 3.0V, and
erase and program operations with VPP at 3.0V or 9.0V. BEFP provides the fastest flash
array programming performance with VPP at 9.0V, which increases factory throughput.
With VPP at 3.0V, VCC and VPP can be tied together for a simple, ultra low power
design. In addition to voltage flexibility, a dedicated VPP connection provides complete
data protection when VPP ≤ VPPLK
.
The CUI is the interface between the system processor and all internal operations of
the device. An internal WSM automatically executes the algorithms and timings
necessary for block erase and program. A Status Register indicates erase or program
completion and any errors that may have occurred.
An industry-standard command sequence invokes program and erase automation. Each
erase operation erases one block. The Erase Suspend feature allows system software to
pause an erase cycle to read or program data in another block. Program Suspend
allows system software to pause programming to read other locations. Data is
programmed in word increments (16 bits).
The Intel® P33 device protection register allows unique flash device identification that
can be used to increase system security. The individual Block Lock feature provides
zero-latency block locking and unlocking. In addition, the Intel® P33 device may also
pre-define main array space as OTP.
2.1
Virtual Chip Enable Description
The 512 Mbit Intel® P33 device employs a Virtual Chip Enable which combines two
256-Mbit die with a common chip enable, F1-CE# for QUAD+ packages or CE# for Easy
BGA packages (refer to Figure 10 and Figure 11 for additional details). Address A24
(QUAD+ package) or A25 (Easy BGA and TSOP package) is then used to select
between the die pair with F1-CE# / CE# asserted, depending upon the package option
used. When chip enable is asserted and QUAD+ A24 (Easy BGA A25) is low (VIL), The
lower parameter die is selected; when chip enable is asserted and QUAD+ A24 (Easy
BGA A25) is high (VIH), the upper parameter die is selected. Refer to Table 1, “Flash Die
Virtual Chip Enable Truth Table for 512 Mbit QUAD+ Package” and Table 2, “Flash Die
Virtual Chip Enable Truth Table for 512 Mbit TSOP / Easy BGA Package” for additional
details.

Name and Function
ADDRESS INPUTS: Device address inputs. 64-Mbit: A[22:1]; 128-Mbit: A[23:1]; 256-Mbit:
A[24:1]; 512-Mbit: A[25:1]. Note: The virtual selection of the 256-Mbit “Top parameter” die in the
dual-die 512-Mbit configuration is accomplished by setting A25 high (VIH).
A[MAX:1]
DQ[15:0]
Input
DATA INPUT/OUTPUTS: Inputs data and commands during write cycles; outputs data during
memory, Status Register, Protection Register, and Read Configuration Register reads. Data balls float
when the CE# or OE# are deasserted. Data is internally latched during writes.
Input/
Output
ADDRESS VALID: Active low input. During synchronous read operations, addresses are latched on
the rising edge of ADV#, or on the next valid CLK edge with ADV# low, whichever occurs first.
ADV#
Input
In asynchronous mode, the address is latched when ADV# going high or continuously flows through
if ADV# is held low.
WARNING: Designs not using ADV# must tie it to VSS to allow addresses to flow through.
CHIP ENABLE: Active low input. CE# low selects the associated flash memory die. When asserted,
flash internal control logic, input buffers, decoders, and sense amplifiers are active. When
deasserted, the associated flash die is deselected, power is reduced to standby levels, data and
WAIT outputs are placed in high-Z state.
CE#
CLK
Input
Input
WARNING: All chip enables must be high when device is not in use.
CLOCK: Synchronizes the device with the system’s bus frequency in synchronous-read mode. During
synchronous read operations, addresses are latched on the rising edge of ADV#, or on the next valid
CLK edge with ADV# low, whichever occurs first.
WARNING: Designs not using CLK for synchronous read mode must tie it to VCCQ or VSS.
OUTPUT ENABLE: Active low input. OE# low enables the device’s output data buffers during read
cycles. OE# high places the data outputs and WAIT in High-Z.
OE#
Input
Input
RESET: Active low input. RST# resets internal automation and inhibits write operations. This
provides data protection during power transitions. RST# high enables normal operation. Exit from
reset places the device in asynchronous read array mode.
RST#
WAIT: Indicates data valid in synchronous array or non-array burst reads. RCR[10], (WT)
determines its polarity when asserted. WAIT’s active output is VOL or VOH when CE# and OE# are
VIL. WAIT is high-Z if CE# or OE# is VIH
.
WAIT
Output
•

In synchronous array or non-array read modes, WAIT indicates invalid data when asserted and
valid data when deasserted.
In asynchronous page mode, and all write modes, WAIT is deasserted.
WRITE ENABLE: Active low input. WE# controls writes to the device. Address and data are latched

on the rising edge of WE#.
WRITE PROTECT: Active low input. WP# low enables the lock-down mechanism. Blocks in lock-
down cannot be unlocked with the Unlock command. WP# high overrides the lock-down function
enabling blocks to be erased or programmed using software commands.
Erase and Program Power: A valid voltage on this pin allows erasing or programming. Memory
contents cannot be altered when VPP ≤ VPPLK. Block erase and program at invalid VPP voltages should
not be attempted.
Set VPP = VPPL for in-system program and erase operations. To accommodate resistor or diode drops
from the system supply, the VIH level of VPP can be as low as VPPL min. VPP must remain above VPPL
min to perform in-system flash modification. VPP may be 0 V during read operations.
VPPH can be applied to main blocks for 1000 cycles maximum and to parameter blocks for 2500
cycles. VPP can be connected to 9 V for a cumulative total not to exceed 80 hours. Extended use of
this pin at 9 V may reduce block cycling capability.

Notes:
1.
Voltages shown are specified with respect to VSS. Minimum DC voltage is –0.5 V on input/output
signals and –0.2 V on VCC, VCCQ, and VPP. During transitions, this level may undershoot to –2.0 V for
periods less than 20 ns. Maximum DC voltage on VCC is VCC + 0.5 V, which, during transitions, may
overshoot to VCC + 2.0 V for periods less than 20 ns. Maximum DC voltage on input/output signals
and VCCQ is VCCQ + 0.5 V, which, during transitions, may overshoot to VCCQ + 2.0 V for periods less
than 20 ns.
2.
3.
Maximum DC voltage on VPP may overshoot to +11.5 V for periods less than 20 ns.
Program/erase voltage is typically 2.3 V – 3.6 V. 9.0 V can be applied for 80 hours maximum total, to
any blocks for 1000 cycles maximum. 9.0 V program/erase voltage may reduce block cycling
capability.
4.
Output shorted for no more than one second. No more than one output shorted at a time.

Write timing characteristics during erase suspend are the same as write-only operations.
A write operation can be terminated with either CE# or WE#.
Sampled, not 100% tested.
Write pulse width low (tWLWH or tELEH) is defined from CE# or WE# low (whichever occurs last) to
CE# or WE# high (whichever occurs first). Hence, tWLWH = tELEH = tWLEH = tELWH
.
5.
Write pulse width high (tWHWL or tEHEL) is defined from CE# or WE# high (whichever occurs first) to
CE# or WE# low (whichever occurs last). Hence, tWHWL = tEHEL = tWHEL = tEHWL).
tWHVH or tWHCH/L must be met when transitioning from a write cycle to a synchronous burst read.
VPP and WP# should be at a valid level until erase or program success is determined.
This specification is only applicable when transitioning from a write cycle to an asynchronous read.
See spec W19 and W20 for synchronous read.
6.

When doing a Read Status operation following any command that alters the Status Register, W14 is
20 ns.
10.
11.
Add 10 ns if the write operations results in a RCR or block lock status change, for the subsequent
read operation to reflect this change.
These specs are required only when the device is in a synchronous mode and clock is active during
address setup phase.

Power and Reset Specifications
8.1
Power-Up and Power-Down
Power supply sequencing is not required if VPP is connected to VCC or VCCQ. Otherwise
VCC and VCCQ should attain their minimum operating voltage before applying VPP.
Power supply transitions should only occur when RST# is low. This protects the device
from accidental programming or erasure during power transitions.
8.2
Reset Specifications
Asserting RST# during a system reset is important with automated program/erase
devices because systems typically expect to read from flash memory when coming out
of reset. If a CPU reset occurs without a flash memory reset, proper CPU initialization
may not occur. This is because the flash memory may be providing status information,
instead of array data as expected. Connect RST# to the same active low reset signal
used for CPU initialization.
Also, because the device is disabled when RST# is asserted, it ignores its control inputs
during power-up/down. Invalid bus conditions are masked, providing a level of memory
protection.

When RST# is tied to the VCC supply, device will not be ready until tVCCPH after VCC ≥ VCCMIN
.
When RST# is tied to the VCCQ supply, device will not be ready until tVCCPH after VCC ≥ VCCMIN..

Power Supply Decoupling
Flash memory devices require careful power supply de-coupling. Three basic power
supply current considerations are: 1) standby current levels; 2) active current levels;
and 3) transient peaks produced when CE# and OE# are asserted and deasserted.
When the device is accessed, many internal conditions change. Circuits within the
device enable charge-pumps, and internal logic states change at high speed. All of
these internal activities produce transient signals. Transient current magnitudes depend
on the device outputs’ capacitive and inductive loading. Two-line control and correct
de-coupling capacitor selection suppress transient voltage peaks.
Because Intel® MLC flash memory devices draw their power from VCC, VPP, and VCCQ,
each power connection should have a 0.1 µF ceramic capacitor to ground. High-
frequency, inherently low-inductance capacitors should be placed as close as possible
to package leads.
Additionally, for every eight devices used in the system, a 4.7 µF electrolytic capacitor
should be placed between power and ground close to the devices. The bulk capacitor is
meant to overcome voltage droop caused by PCB trace inductance.

Device Operations
This section provides an overview of device operations. The system Central Processing
Unit provides control of all in-system read, write, and erase operations of the device via
the system bus. The on-chip WSM manages all block-erase and word-program
algorithms.
Device commands are written to the CUI to control all flash memory device operations.
The CUI does not occupy an addressable memory location; it is the mechanism through
which the flash device is controlled.
9.1
Bus Operations
CE# low and RST# high enable device read operations. The device internally decodes
upper address inputs to determine the accessed block. ADV# low opens the internal
address latches. OE# low activates the outputs and gates selected data onto the I/O
bus.
In asynchronous mode, the address is latched when ADV# goes high or continuously
flows through if ADV# is held low. In synchronous mode, the address is latched by the
first of either the rising ADV# edge or the next valid CLK edge with ADV# low (WE#
and RST# must be VIH; CE# must be VIL).
Bus cycles to/from the Intel StrataFlash® Embedded Memory P33 device conform to
standard microprocessor bus operations. Table 20 summarizes the bus operations and
the logic levels that must be applied to the device control signal inputs.

9.1.1
9.1.2
Reads
To perform a read operation, RST# and WE# must be deasserted while CE# and OE#
are asserted. CE# is the device-select control. When asserted, it enables the flash
memory device. OE# is the data-output control. When asserted, the addressed flash
memory data is driven onto the I/O bus. See Section 10.0, “Read Operations” on
page 51 for details on the available read modes, and see Section 14.0, “Special Read
States” on page 73 for details regarding the available read states.
Writes
To perform a write operation, both CE# and WE# are asserted while RST# and OE# are
deasserted. During a write operation, address and data are latched on the rising edge
of WE# or CE#, whichever occurs first. Table 21, “Command Bus Cycles” on page 48
Datasheet
46
November 2007
Order Number: 314749-004
Intel StrataFlash® Embedded Memory P33
shows the bus cycle sequence for each of the supported device commands, while
Table 22, “Command Codes and Definitions” on page 49 describes each command. See
Section 7.0, “AC Characteristics” on page 32 for signal-timing details.
Note:
Write operations with invalid VCC and/or VPP voltages can produce spurious results and
should not be attempted.
9.1.3
Output Disable
When OE# is deasserted, device outputs DQ[15:0] are disabled and placed in a high-
impedance (High-Z) state, WAIT is also placed in High-Z.
9.1.4
Standby
When CE# is deasserted the device is deselected and placed in standby, substantially
reducing power consumption. In standby, the data outputs are placed in High-Z,
independent of the level placed on OE#. Standby current, ICCS, is the average current
measured over any 5 ms time interval, 5 μs after CE# is deasserted. During standby,
average current is measured over the same time interval 5 μs after CE# is deasserted.
When the device is deselected (while CE# is deasserted) during a program or erase
operation, it continues to consume active power until the program or erase operation is
completed.
9.1.5
Reset
As with any automated device, it is important to assert RST# when the system is reset.
When the system comes out of reset, the system processor attempts to read from the
flash memory if it is the system boot device. If a CPU reset occurs with no flash
memory reset, improper CPU initialization may occur because the flash memory may
be providing status information rather than array data. Flash memory devices from
Intel allow proper CPU initialization following a system reset through the use of the
RST# input. RST# should be controlled by the same low-true reset signal that resets
the system CPU.
After initial power-up or reset, the device defaults to asynchronous Read Array mode,
and the Status Register is set to 0x80. Asserting RST# de-energizes all internal
circuits, and places the output drivers in High-Z. When RST# is asserted, the device
shuts down the operation in progress, a process which takes a minimum amount of
time to complete. When RST# has been deasserted, the device is reset to
asynchronous Read Array state.
Note:
If RST# is asserted during a program or erase operation, the operation is terminated
and the memory contents at the aborted location (for a program) or block (for an
erase) are no longer valid, because the data may have been only partially written or
erased.
When returning from a reset (RST# deasserted), a minimum wait is required before the
initial read access outputs valid data. Also, a minimum delay is required after a reset
before a write cycle can be initiated. After this wake-up interval passes, normal
operation is restored. See Section 7.0, “AC Characteristics” on page 32 for details
about signal-timing.
9.2
Device Commands
Device operations are initiated by writing specific device commands to the CUI. See
Table 21, “Command Bus Cycles” on page 48. Several commands are used to modify
array data including Word Program and Block Erase commands. Writing either
November 2007

Intel StrataFlash® Embedded Memory P33
command to the CUI initiates a sequence of internally-timed functions that culminate in
the completion of the requested task. However, the operation can be aborted by either
asserting RST# or by issuing an appropriate suspend command.

Read Operations
The device supports two read modes: asynchronous page mode and synchronous burst
mode. Asynchronous page mode is the default read mode after device power-up or a
reset. The RCR must be configured to enable synchronous burst reads of the flash
memory array (see Section 10.3, “Read Configuration Register” on page 52).
The device can be in any of four read states: Read Array, Read Identifier, Read Status
or Read Query. Upon power-up, or after a reset, the device defaults to Read Array
mode. To change the read state, the appropriate read command must be written to the
device (see Section 9.2, “Device Commands” on page 47). See Section 14.0, “Special
Read States” on page 73 for details regarding Read Status, Read ID, and CFI Query
modes.
The following sections describe read-mode operations in detail.
10.1
Asynchronous Page-Mode Read
Following a device power-up or reset, asynchronous page mode is the default read
mode and the device is set to Read Array mode. However, to perform array reads after
any other device operation (e.g. write operation), the Read Array command must be
issued in order to read from the flash memory array.
Note:
Asynchronous page-mode reads can only be performed when RCR 15 is set (see
Section 10.3, “Read Configuration Register” on page 52).
To perform an asynchronous page-mode read, an address is driven onto the address
bus, and CE# and ADV# are asserted. WE# and RST# must already have been
deasserted. WAIT is deasserted during asynchronous page mode. ADV# can be driven
high to latch the address, or it must be held low throughout the read cycle. CLK is not
used for asynchronous page-mode reads, and is ignored. If only asynchronous reads
are to be performed, CLK should be tied to a valid VIH level, WAIT signal can be floated
and ADV# must be tied to ground. Array data is driven onto DQ[15:0] after an initial
access time tAVQV delay. (see Section 7.0, “AC Characteristics” on page 32).
In asynchronous page mode, four data words are “sensed” simultaneously from the
flash memory array and loaded into an internal page buffer. The buffer word
corresponding to the initial address on the Address bus is driven onto DQ[15:0] after
the initial access delay. The lowest two address bits determine which word of the
4-word page is output from the data buffer at any given time.
10.2
Synchronous Burst-Mode Read
To perform a synchronous burst-read, an initial address is driven onto the address bus,
and CE# and ADV# are asserted. WE# and RST# must already have been deasserted.
ADV# is asserted, and then deasserted to latch the address. Alternately, ADV# can
remain asserted throughout the burst access, in which case the address is latched on
the next valid CLK edge while ADV# is asserted.
During synchronous array and non-array read modes, the first word is output from the
data buffer on the next valid CLK edge after the initial access latency delay (see Section
10.3.2, “Latency Count” on page 53). Subsequent data is output on valid CLK edges
following a minimum delay. However, for a synchronous non-array read, the same word
of data will be output on successive clock edges until the burst length requirements are
satisfied. Refer to the following waveforms for more detailed information:
• Figure 18, “Synchronous Single-Word Array or Non-array Read Timing” on page 38

10.3
Read Configuration Register
The RCR is used to select the read mode (synchronous or asynchronous), and it defines
the synchronous burst characteristics of the device. To modify RCR settings, use the
Configure Read Configuration Register command (see Section 9.2, “Device Commands”
on page 47).
RCR contents can be examined using the Read Device Identifier command, and then
reading from offset 0x05 (see Section 14.2, “Read Device Identifier” on page 74).
The RCR is shown in Table 23. The following sections describe each RCR bit.

Read Mode
The Read Mode (RM) bit selects synchronous burst-mode or asynchronous page-mode
operation for the device. When the RM bit is set, asynchronous page mode is selected
(default). When RM is cleared, synchronous burst mode is selected.
Latency Count
The Latency Count (LC) bits tell the device how many clock cycles must elapse from the
rising edge of ADV# (or from the first valid clock edge after ADV# is asserted) until the
first valid data word is driven onto DQ[15:0]. The input clock frequency is used to
determine this value and Figure 27 shows the data output latency for the different
settings of LC. The maximum Latency Count for P33 would be Code 4 based on the Max
clock frequency specification of 52 Mhz, and there will be zero WAIT States when
bursting within the word line. Please also refer to Section 10.3.10, “End of Word Line
(EOWL) Considerations” on page 58 for more information on EOWL.

WAIT Polarity
The WAIT Polarity bit (WP), RCR 10 determines the asserted level (VOH or VOL) of WAIT.
When WP is set, WAIT is asserted high (default). When WP is cleared, WAIT is asserted
low. WAIT changes state on valid clock edges during active bus cycles (CE# asserted,
OE# asserted, RST# deasserted).
10.3.3.1
WAIT Signal Function
The WAIT signal indicates data valid when the device is operating in synchronous mode
(RCR 15=0). The WAIT signal is only “deasserted” when data is valid on the bus.
When the device is operating in synchronous non-array read mode, such as read
status, read ID, or read query. The WAIT signal is also “deasserted” when data is valid
on the bus.
WAIT behavior during synchronous non-array reads at the end of word line works
correctly only on the first data access.
When the device is operating in asynchronous page mode, asynchronous single word
read mode, and all write operations, WAIT is set to a deasserted state as determined
by RCR 10. See Figure 16, “Asynchronous Single-Word Read (ADV# Latch)” on
page 37, and Figure 17, “Asynchronous Page-Mode Read Timing” on page 38.

10.3.4
Data Hold
For burst read operations, the Data Hold (DH) bit determines whether the data output
remains valid on DQ[15:0] for one or two clock cycles. This period of time is called the
“data cycle”. When DH is set, output data is held for two clocks (default). When DH is
cleared, output data is held for one clock (see Figure 29). The processor’s data setup
time and the flash memory’s clock-to-data output delay should be considered when
determining whether to hold output data for one or two clocks. A method for
determining the DH configuration is shown below:
To set the device at one clock data hold for subsequent reads, the following condition
must be satisfied:
tCHQV (ns) + tDATA (ns) ≤ One CLK Period (ns)
tDATA = Data set up to Clock (defined by CPU)
For example, with a clock frequency of 40 MHz, the clock period is 25 ns. Assuming
tCHQV = 20 ns and tDATA = 4 ns. Applying these values to the formula above:
20 ns + 4 ns ≤ 25 ns
The equation is satisfied and data will be available at every clock period with data hold
setting at one clock. If tCHQV (ns) + tDATA (ns) > One CLK Period (ns), data hold setting
of 2 clock periods must be used.

10.3.5
WAIT Delay
The WAIT Delay (WD) bit controls the WAIT assertion-delay behavior during
synchronous burst reads. WAIT can be asserted either during or one data cycle before
valid data is output on DQ[15:0]. When WD is set, WAIT is deasserted one data cycle
before valid data (default). When WD is cleared, WAIT is deasserted during valid data.
10.3.6
Burst Sequence
The Burst Sequence (BS) bit selects linear-burst sequence (default). Only linear-burst
sequence is supported. Table 26 shows the synchronous burst sequence for all burst
lengths, as well as the effect of the Burst Wrap (BW) setting.

The Burst Length bits (BL[2:0]) selects the linear burst length for all synchronous burst
reads of the flash memory array. The burst lengths are 4-word, 8-word, 16-word, and
continuous word.
Continuous burst accesses are linear only, and do not wrap within any word length
boundaries (see Table 26, “Burst Sequence Word Ordering” on page 57). When a burst
cycle begins, the device outputs synchronous burst data until it reaches the end of the
“burstable” address space.
10.3.10
End of Word Line (EOWL) Considerations
When performing synchronous burst reads with BW set (no wrap) and DH reset (1-
clock cycle), an output “delay” requiring additional clock Wait States may occur when
the burst sequence crosses its first device-row (16-word) boundary. The delay would
take place only once, and will not occur if the burst sequence does not cross a device-
row boundary. The WAIT signal informs the system of this delay when it occurs. If the
burst sequence’s start address is 4-word aligned (i.e. 0x00h, 0x04h, 0x08, 0x0Ch) then
no delay occurs. If the start address is at the end of a 4-word boundary (i.e. 0x03h,
0x07h, 0x0Bh, 0x0Fh), the worst case delay (number of Wait States required) will be
one clock cycle less than the first access Latency Count (LC-1) when crossing the first
device-row boundary (i.e. 0x0Fh to 0x10h). Other address misalignments may require
wait states depending upon the LC setting and the starting address alignment. For
example, an LC setting of 3 with a starting address of 0xFD requires 0 wait states, but
the same LC setting of 3 with a starting address of 0xFE would require 1 wait state
when crossing the first device row boundary.

Programming Operations
The device supports three programming methods: Word Programming (40h/10h),
Buffered Programming (E8h, D0h), and Buffered Enhanced Factory Programming (80h,
D0h). See Section 9.0, “Device Operations” on page 46 for details on the various
programming commands issued to the device. The following sections describe device
programming in detail.
Successful programming requires the addressed block to be unlocked. If the block is
locked down, WP# must be deasserted and the block must be unlocked before
attempting to program the block. Attempting to program a locked block causes a
program error (SR[4] and SR[1] set) and termination of the operation. See Section
13.0, “Security Modes” on page 67 for details on locking and unlocking blocks.
The Intel StrataFlash® Embedded Memory (P33) is segmented into multiple 8-Mbit
Programming Regions. See Section 4.4, “Memory Maps” on page 24 for complete
addressing. Execute in Place (XIP) applications must partition the memory such that
code and data are in separate programming regions. XIP is executing code directly
from flash memory. Each Programming Region should contain only code or data but not
both. The following terms define the difference between code and data. System designs
must use these definitions when partitioning their code and data for the Intel
StrataFlash® Embedded Memory P33 device.
Code :
Data :
Execution code ran out of the flash device on a continuous basis in the system.
Information periodically programmed into the flash device and read back (e.g. execution code
shadowed and executed in RAM, pictures, log files, etc.).
11.1
Word Programming
Word programming operations are initiated by writing the Word Program Setup
command to the device (see Section 9.0, “Device Operations” on page 46). This is
followed by a second write to the device with the address and data to be programmed.
The device outputs Status Register data when read. See Figure 39, “Word Program
Flowchart” on page 83. VPP must be above VPPLK, and within the specified VPPL min/
max values.
During programming, the WSM executes a sequence of internally-timed events that
program the desired data bits at the addressed location, and verifies that the bits are
sufficiently programmed. Programming the flash memory array changes “ones” to
“zeros”. Memory array bits that are zeros can be changed to ones only by erasing the
block (see Section 12.0, “Erase Operations” on page 65).
The Status Register can be examined for programming progress and errors by reading
at any address. The device remains in the Read Status Register state until another
command is written to the device.
Status Register bit SR[7] indicates the programming status while the sequence
executes. Commands that can be issued to the device during programming are
Program Suspend, Read Status Register, Read Device Identifier, CFI Query, and Read
Array (this returns unknown data).
When programming has finished, Status Register bit SR[4] (when set) indicates a
programming failure. If SR[3] is set, the WSM could not perform the word
programming operation because VPP was outside of its acceptable limits. If SR[1] is set,
the word programming operation attempted to program a locked block, causing the
operation to abort.

Intel StrataFlash® Embedded Memory P33
Before issuing a new command, the Status Register contents should be examined and
then cleared using the Clear Status Register command. Any valid command can follow,
when word programming has completed.
11.1.1
Factory Word Programming
Factory word programming is similar to word programming in that it uses the same
commands and programming algorithms. However, factory word programming
enhances the programming performance with VPP = VPPH. This can enable faster
programming times during OEM manufacturing processes. Factory word programming
is not intended for extended use. See Section 5.2, “Operating Conditions” on page 28
for limitations when VPP = VPPH
.
Note:
When VPP = VPPL, the device draws programming current from the VCC supply. If VPP is
driven by a logic signal, VPPL must remain above VPPL MIN to program the device. When
VPP = VPPH, the device draws programming current from the VPP supply. Figure 30,
“Example VPP Supply Connections” on page 64 shows examples of device power supply
configurations.
11.2
Buffered Programming
The device features a 32-word buffer to enable optimum programming performance.
For Buffered Programming, data is first written to an on-chip write buffer. Then the
buffer data is programmed into the flash memory array in buffer-size increments. This
can improve system programming performance significantly over non-buffered
programming.
When the Buffered Programming Setup command is issued (see Section 9.2, “Device
Commands” on page 47), Status Register information is updated and reflects the
availability of the buffer. SR[7] indicates buffer availability: if set, the buffer is
available; if cleared, the buffer is not available. To retry, issue the Buffered
Programming Setup command again, and re-check SR[7]. When SR[7] is set, the
buffer is ready for loading. (see Figure 41, “Buffer Program Flowchart” on page 85).
On the next write, a word count is written to the device at the buffer address. This tells
the device how many data words will be written to the buffer, up to the maximum size
of the buffer.
On the next write, a device start address is given along with the first data to be written
to the flash memory array. Subsequent writes provide additional device addresses and
data. All data addresses must lie within the start address plus the word count.
Optimum programming performance and lower power usage are obtained by aligning
the starting address at the beginning of a 32-word boundary (A[4:0] = 0x00). Crossing
a 32-word boundary during programming will double the total programming time.
After the last data is written to the buffer, the Buffered Programming Confirm command
must be issued to the original block address. The WSM begins to program buffer
contents to the flash memory array. If a command other than the Buffered
Programming Confirm command is written to the device, a command sequence error
occurs and SR[7,5,4] are set. If an error occurs while writing to the array, the device
stops programming, and SR[7,4] are set, indicating a programming failure.
When Buffered Programming has completed, additional buffer writes can be initiated by
issuing another Buffered Programming Setup command and repeating the buffered
program sequence. Buffered programming may be performed with VPP = VPPL or VPPH
(see Section 5.2, “Operating Conditions” on page 28 for limitations when operating the
device with VPP = VPPH).

If an attempt is made to program past an erase-block boundary using the Buffered
Program command, the device aborts the operation. This generates a command
sequence error, and SR[5,4] are set.
If Buffered programming is attempted while VPP is below VPPLK, SR[4,3] are set. If any
errors are detected that have set Status Register bits, the Status Register should be
cleared using the Clear Status Register command.
11.3
Buffered Enhanced Factory Programming
Buffered Enhanced Factory Programing (BEFP) speeds up Multi-Level Cell (MLC) flash
programming. The enhanced programming algorithm used in BEFP eliminates
traditional programming elements that drive up overhead in device programmer
systems.
BEFP consists of three phases: Setup, Program/Verify, and Exit (see Figure 42, “BEFP
Flowchart” on page 86). It uses a write buffer to spread MLC program performance
across 32 data words. Verification occurs in the same phase as programming to
accurately program the flash memory cell to the correct bit state.
A single two-cycle command sequence programs the entire block of data. This
enhancement eliminates three write cycles per buffer: two commands and the word
count for each set of 32 data words. Host programmer bus cycles fill the device’s write
buffer followed by a status check. SR[0] indicates when data from the buffer has been
programmed into sequential flash memory array locations.
Following the buffer-to-flash array programming sequence, the Write State Machine
(WSM) increments internal addressing to automatically select the next 32-word array
boundary. This aspect of BEFP saves host programming equipment the address-bus
setup overhead.
With adequate continuity testing, programming equipment can rely on the WSM’s
internal verification to ensure that the device has programmed properly. This eliminates
the external post-program verification and its associated overhead.
11.3.1
BEFP Requirements and Considerations
BEFP requirements:
• Case temperature: TC = 25 °C ± 5 °C
• VCC within specified operating range
• VPP driven to VPPH
• Target block unlocked before issuing the BEFP Setup and Confirm commands
• The first-word address for the block to be programmed must be held constant from
the setup phase through all data streaming into the target block, until transition to
the exit phase is desired
• The first-word address must align with the start of an array buffer boundary1

Intel StrataFlash® Embedded Memory P33
BEFP considerations:
• For optimum performance, cycling must be limited below 100 erase cycles per
block2
• BEFP programs one block at a time; all buffer data must fall within a single block3
• BEFP cannot be suspended
• Programming to the flash memory array can occur only when the buffer is full4
Note:
1.
Word buffer boundaries in the array are determined by A[4:0] (0x00 through 0x1F). The alignment
start point is A[4:0] = 0x00.
2.
3.
4.
Some degradation in performance may occur if this limit is exceeded, but the internal algorithm
continues to work properly.
If the internal address counter increments beyond the block's maximum address, addressing wraps
around to the beginning of the block.
If the number of words is less than 32, remaining locations must be filled with 0xFFFF.
11.3.2
BEFP Setup Phase
After receiving the BEFP Setup and Confirm command sequence, Status Register bit
SR[7] (Ready) is cleared, indicating that the WSM is busy with BEFP algorithm startup.
A delay before checking SR[7] is required to allow the WSM enough time to perform all
of its setups and checks (Block-Lock status, VPP level, etc.). If an error is detected,
SR[4] is set and BEFP operation terminates. If the block was found to be locked, SR[1]
is also set. SR[3] is set if the error occurred due to an incorrect VPP level.
Note:
Reading from the device after the BEFP Setup and Confirm command sequence outputs
Status Register data. Do not issue the Read Status Register command; it will be
interpreted as data to be loaded into the buffer.
11.3.3
BEFP Program/Verify Phase
After the BEFP Setup Phase has completed, the host programming system must check
SR[7,0] to determine the availability of the write buffer for data streaming. SR[7]
cleared indicates the device is busy and the BEFP program/verify phase is activated.
SR[0] indicates the write buffer is available.
Two basic sequences repeat in this phase: loading of the write buffer, followed by buffer
data programming to the array. For BEFP, the count value for buffer loading is always
the maximum buffer size of 32 words. During the buffer-loading sequence, data is
stored to sequential buffer locations starting at address 0x00. Programming of the
buffer contents to the flash memory array starts as soon as the buffer is full. If the
number of words is less than 32, the remaining buffer locations must be filled with 0xFFFF.
Caution:
The buffer must be completely filled for programming to occur. Supplying an address
outside of the current block's range during a buffer-fill sequence causes the algorithm
to exit immediately. Any data previously loaded into the buffer during the fill cycle is
not programmed into the array.
The starting address for data entry must be buffer size aligned, if not the BEFP
algorithm will be aborted and the program fails and (SR[4]) flag will be set.

Intel StrataFlash® Embedded Memory P33
Data words from the write buffer are directed to sequential memory locations in the
flash memory array; programming continues from where the previous buffer sequence
ended. The host programming system must poll SR[0] to determine when the buffer
program sequence completes. SR[0] cleared indicates that all buffer data has been
transferred to the flash array; SR[0] set indicates that the buffer is not available yet for
the next fill cycle. The host system may check full status for errors at any time, but it is
only necessary on a block basis after BEFP exit. After the buffer fill cycle, no write
cycles should be issued to the device until SR[0] = 0 and the device is ready for the
next buffer fill.
Note:
Any spurious writes are ignored after a buffer fill operation and when internal program
is proceeding.
The host programming system continues the BEFP algorithm by providing the next
group of data words to be written to the buffer. Alternatively, it can terminate this
phase by changing the block address to one outside of the current block’s range.
The Program/Verify phase concludes when the programmer writes to a different block
address; data supplied must be 0xFFFF. Upon Program/Verify phase completion, the
device enters the BEFP Exit phase.
11.3.4
11.4
BEFP Exit Phase
When SR[7] is set, the device has returned to normal operating conditions. A full status
check should be performed at this time to ensure the entire block programmed
successfully. When exiting the BEFP algorithm with a block address change, the read
mode will not change. After BEFP exit, any valid command can be issued to the device.
Program Suspend
Issuing the Program Suspend command while programming suspends the
programming operation. This allows data to be accessed from the device other than the
one being programmed. The Program Suspend command can be issued to any device
address. A program operation can be suspended to perform reads only. Additionally, a
program operation that is running during an erase suspend can be suspended to
perform a read operation (see Figure 40, “Program Suspend/Resume Flowchart” on
page 84).
When a programming operation is executing, issuing the Program Suspend command
requests the WSM to suspend the programming algorithm at predetermined points. The
device continues to output Status Register data after the Program Suspend command is
issued. Programming is suspended when Status Register bits SR[7,2] are set. Suspend
latency is specified in Section 7.5, “Program and Erase Characteristics” on page 43.
To read data from the device, the Read Array command must be issued. Read Array,
Read Status Register, Read Device Identifier, CFI Query, and Program Resume are valid
commands during a program suspend.
During a program suspend, deasserting CE# places the device in standby, reducing
active current. VPP must remain at its programming level, and WP# must remain
unchanged while in program suspend. If RST# is asserted, the device is reset.
11.5
Program Resume
The Resume command instructs the device to continue programming, and
automatically clears Status Register bits SR[7,2]. This command can be written to any
address. If error bits are set, the Status Register should be cleared before issuing the
next instruction. RST# must remain deasserted (see Figure 40, “Program Suspend/
Resume Flowchart” on page 84).

Erase Operations
Flash erasing is performed on a block basis. An entire block is erased each time an
erase command sequence is issued, and only one block is erased at a time. When a
block is erased, all bits within that block read as logical ones. The following sections
describe block erase operations in detail.
12.1
Block Erase
Block erase operations are initiated by writing the Block Erase Setup command to the
address of the block to be erased (see Section 9.2, “Device Commands” on page 47).
Next, the Block Erase Confirm command is written to the address of the block to be
erased. If the device is placed in standby (CE# deasserted) during an erase operation,
the device completes the erase operation before entering standby. VPP must be above
VPPLK and the block must be unlocked (see Figure 43, “Block Erase Flowchart” on
page 87).
During a block erase, the WSM executes a sequence of internally-timed events that
conditions, erases, and verifies all bits within the block. Erasing the flash memory array
changes “zeros” to “ones”. Memory array bits that are ones can be changed to zeros
only by programming the block (see Section 11.0, “Programming Operations” on
page 59).
The Status Register can be examined for block erase progress and errors by reading
any address. The device remains in the Read Status Register state until another
command is written. SR[0] indicates whether the addressed block is erasing. Status
Register bit SR[7] is set upon erase completion.
Status Register bit SR[7] indicates block erase status while the sequence executes.
When the erase operation has finished, Status Register bit SR[5] indicates an erase
failure if set. SR[3] set would indicate that the WSM could not perform the erase
operation because VPP was outside of its acceptable limits. SR[1] set indicates that the
erase operation attempted to erase a locked block, causing the operation to abort.
Before issuing a new command, the Status Register contents should be examined and
then cleared using the Clear Status Register command. Any valid command can follow
once the block erase operation has completed.
12.2
Erase Suspend
Issuing the Erase Suspend command while erasing suspends the block erase operation.
This allows data to be accessed from memory locations other than the one being
erased. The Erase Suspend command can be issued to any device address. A block
erase operation can be suspended to perform a word or buffer program operation, or a
read operation within any block except the block that is erase suspended (see
Figure 40, “Program Suspend/Resume Flowchart” on page 84).
When a block erase operation is executing, issuing the Erase Suspend command
requests the WSM to suspend the erase algorithm at predetermined points. The device
continues to output Status Register data after the Erase Suspend command is issued.
Block erase is suspended when Status Register bits SR[7,6] are set. Suspend latency is
specified in Section 7.5, “Program and Erase Characteristics” on page 43.
To read data from the device (other than an erase-suspended block), the Read Array
command must be issued. During Erase Suspend, a Program command can be issued
to any block other than the erase-suspended block. Block erase cannot resume until
program operations initiated during erase suspend complete. Read Array, Read Status
Register, Read Device Identifier, CFI Query, and Erase Resume are valid commands

during Erase Suspend. Additionally, Clear Status Register, Program, Program Suspend,
Block Lock, Block Unlock, and Block Lock-Down are valid commands during Erase
Suspend.
During an erase suspend, deasserting CE# places the device in standby, reducing
active current. VPP must remain at a valid level, and WP# must remain unchanged
while in erase suspend. If RST# is asserted, the device is reset.
12.3
12.4
Erase Resume
The Erase Resume command instructs the device to continue erasing, and
automatically clears SR[7,6]. This command can be written to any address. If status
register error bits are set, the Status Register should be cleared before issuing the next
instruction. RST# must remain deasserted (see Figure 40, “Program Suspend/Resume
Flowchart” on page 84).
Erase Protection
When VPP = VIL, absolute hardware erase protection is provided for all device blocks. If
VPP is below VPPLK, erase operations halt and SR[3] is set indicating a VPP-level error.

Security Modes
The device features security modes used to protect the information stored in the flash
memory array. The following sections describe each security mode in detail.
13.1
Block Locking
Individual instant block locking is used to protect user code and/or data within the flash
memory array. All blocks power up in a locked state to protect array data from being
altered during power transitions. Any block can be locked or unlocked with no latency.
Locked blocks cannot be programmed or erased; they can only be read.
Software-controlled security is implemented using the Block Lock and Block Unlock
commands. Hardware-controlled security can be implemented using the Block Lock-
Down command along with asserting WP#. Also, VPP data security can be used to
inhibit program and erase operations (see Section 11.6, “Program Protection” on
page 64 and Section 12.4, “Erase Protection” on page 66).
The Intel StrataFlash® Embedded Memory P33 device also offers four pre-defined areas
in the main array that can be configured as One-Time Programmable (OTP) for the
highest level of security. These include the four 32 KB parameter blocks together as
one and the three adjacent 128 KB main blocks. This is available for top or bottom
parameter devices.
13.1.1
13.1.2
Lock Block
To lock a block, issue the Lock Block Setup command. The next command must be the
Lock Block command issued to the desired block’s address (see Section 9.2, “Device
Commands” on page 47 and Figure 45, “Block Lock Operations Flowchart” on page 90).
If the Set Read Configuration Register command is issued after the Block Lock Setup
command, the device configures the RCR instead.
Block lock and unlock operations are not affected by the voltage level on VPP. The block
lock bits may be modified and/or read even if VPP is at or below VPPLK
.
Unlock Block
The Unlock Block command is used to unlock blocks (see Section 9.2, “Device
Commands” on page 47). Unlocked blocks can be read, programmed, and erased.
Unlocked blocks return to a locked state when the device is reset or powered down. If a
block is in a lock-down state, WP# must be deasserted before it can be unlocked (see
Figure 31, “Block Locking State Diagram” on page 68).

13.1.3
Lock-Down Block
A locked or unlocked block can be locked-down by writing the Lock-Down Block
command sequence (see Section 9.2, “Device Commands” on page 47). Blocks in a
lock-down state cannot be programmed or erased; they can only be read. However,
unlike locked blocks, their locked state cannot be changed by software commands
alone. A locked-down block can only be unlocked by issuing the Unlock Block command
with WP# deasserted. To return an unlocked block to locked-down state, a Lock-Down
command must be issued prior to changing WP# to VIL. Locked-down blocks revert to
the locked state upon reset or power up the device (see Figure 31, “Block Locking State
Diagram” on page 68).
13.1.4
Block Lock Status
The Read Device Identifier command is used to determine a block’s lock status (see
Section 14.2, “Read Device Identifier” on page 74). Data bits DQ[1:0] display the
addressed block’s lock status; DQ0 is the addressed block’s lock bit, while DQ1 is the
addressed block’s lock-down bit.

13.1.5
Block Locking During Suspend
Block lock and unlock changes can be performed during an erase suspend. To change
block locking during an erase operation, first issue the Erase Suspend command.
Monitor the Status Register until SR[7] and SR[6] are set, indicating the device is
suspended and ready to accept another command.
Next, write the desired lock command sequence to a block, which changes the lock
state of that block. After completing block lock or unlock operations, resume the erase
operation using the Erase Resume command.

Note:
A Lock Block Setup command followed by any command other than Lock Block, Unlock
Block, or Lock-Down Block produces a command sequence error and set Status
Register bits SR[4] and SR[5]. If a command sequence error occurs during an erase
suspend, SR[4] and SR[5] remains set, even after the erase operation is resumed.
Unless the Status Register is cleared using the Clear Status Register command before
resuming the erase operation, possible erase errors may be masked by the command
sequence error.
If a block is locked or locked-down during an erase suspend of the same block, the lock
status bits change immediately. However, the erase operation completes when it is
resumed. Block lock operations cannot occur during a program suspend. See Appendix
A, “Write State Machine” on page 76, which shows valid commands during an erase
suspend.

Protection Registers
The device contains 17 Protection Registers (PR) that can be used to implement system
security measures and/or device identification. Each Protection Register can be
individually locked.
The first 128-bit Protection Register is comprised of two 64-bit (8-word) segments. The
lower 64-bit segment is pre-programmed at the Intel factory with a unique 64-bit
number. The other 64-bit segment, as well as the other sixteen 128-bit Protection
Registers, are blank. Users can program these registers as needed. When programmed,
users can then lock the Protection Register(s) to prevent additional bit programming
(see Figure 32, “Protection Register Map” on page 71).
The user-programmable Protection Registers contain one-time programmable (OTP)
bits; when programmed, PR bits cannot be erased. Each Protection Register can be
accessed multiple times to program individual bits, as long as the register remains
unlocked.
Each Protection Register has an associated Lock Register bit. When a Lock Register bit
is programmed, the associated Protection Register can only be read; it can no longer be
programmed. Additionally, because the Lock Register bits themselves are OTP, when
programmed, Lock Register bits cannot be erased. Therefore, when a Protection
Register is locked, it cannot be unlocked.

13.3.2
Reading the Protection Registers
The Protection Registers can be read from any address. To read the Protection Register,
first issue the Read Device Identifier command at any address to place the device in the
Read Device Identifier state (see Section 9.2, “Device Commands” on page 47). Next,
perform a read operation using the address offset corresponding to the register to be
read. Table 29, “Device Identifier Information” on page 75 shows the address offsets of
the Protection Registers and Lock Registers. PR data is read 16 bits at a time.
Programming the Protection Registers
To program any of the Protection Registers, first issue the Program Protection Register
command at the parameter’s base address plus the offset to the desired Protection
Register (see Section 9.2, “Device Commands” on page 47). Next, write the desired
Protection Register data to the same Protection Register address (see Figure 32,
“Protection Register Map” on page 71).
The device programs the 64-bit and 128-bit user-programmable Protection Register
data 16 bits at a time (see Figure 46, “Protection Register Programming Flowchart” on
page 91). Issuing the Program Protection Register command outside of the Protection
Register’s address space causes a program error (SR[4] set). Attempting to program a
locked Protection Register causes a program error (SR[4] set) and a lock error (SR[1]
set).
Note:
When programming the OTP bits in the protection registers for a Top Parameter
Device, the following upper address bits must also be driven properly: A[Max:17]
driven high (VIH) for TSOP and Easy BGA packages, and A[Max:16] driven high (VIH)
for QUAD+ SCSP.
13.3.3
Locking the Protection Registers
Each Protection Register can be locked by programming its respective lock bit in the
Lock Register. To lock a Protection Register, program the corresponding bit in the Lock
Register by issuing the Program Lock Register command, followed by the desired Lock
Register data (see Section 9.2, “Device Commands” on page 47). The physical
addresses of the Lock Registers are 0x80 for register 0 and 0x89 for register 1. These
addresses are used when programming the lock registers (see Table 29, “Device
Identifier Information” on page 75).
Bit 0 of Lock Register 0 is already programmed during the manufacturing process at the
“factory”, locking the lower, pre-programmed 64-bit region of the first 128-bit
Protection Register containing the unique identification number of the device. Bit 1 of
Lock Register 0 can be programmed by the user to lock the user-programmable, 64-bit
region of the first 128-bit Protection Register. When programming Bit 1 of Lock Register
0, all other bits need to be left as ‘1’ such that the data programmed is 0xFFFD.
Lock Register 1 controls the locking of the upper sixteen 128-bit Protection Registers.
Each of the 16 bits of Lock Register 1 correspond to each of the upper sixteen 128-bit
Protection Registers. Programming a bit in Lock Register 1 locks the corresponding
128-bit Protection Register.
Caution:
After being locked, the Protection Registers cannot be unlocked.

Special Read States
The following sections describe non-array read states. Non-array reads can be
performed in asynchronous read or synchronous burst mode. A non-array read
operation occurs as asynchronous single-word mode. When non-array reads are
performed in asynchronous page mode only the first data is valid and all subsequent
data are undefined. When a non-array read operation occurs as synchronous burst
mode, the same word of data requested will be output on successive clock edges until
the burst length requirements are satisfied.
Refer to the following waveforms for more detailed information:
• Figure 15, “Asynchronous Single-Word Read (ADV# Low)” on page 37
• Figure 16, “Asynchronous Single-Word Read (ADV# Latch)” on page 37
• Figure 18, “Synchronous Single-Word Array or Non-array Read Timing” on page 38
14.1
Read Status Register
To read the Status Register, issue the Read Status Register command at any address.
Status Register information is available to which the Read Status Register, Word
Program, or Block Erase command was issued. SRD is automatically made available
following a Word Program, Block Erase, or Block Lock command sequence. Reads from
the device after any of these command sequences outputs the device’s status until
another valid command is written (e.g. the Read Array command).
The Status Register is read using single asynchronous-mode or synchronous burst
mode reads. SRD is output on DQ[7:0], while 0x00 is output on DQ[15:8]. In
asynchronous mode the falling edge of OE#, or CE# (whichever occurs first) updates
and latches the Status Register contents. However, when reading the Status Register in
synchronous burst mode, CE# or ADV# must be toggled to update SRD.
The Device Write Status bit (SR[7]) provides overall status of the device. SR[6:1]
present status and error information about the program, erase, suspend, VPP, and
block-locked operations.

Note:
Always clear the Status Register prior to resuming erase operations. It avoids Status
Register ambiguity when issuing commands during Erase Suspend. If a command
sequence error occurs during an erase-suspend state, the Status Register contains the
command sequence error status (SR[7,5,4] set). When the erase operation resumes
and finishes, possible errors during the erase operation cannot be detected via the
Status Register because it contains the previous error status.
14.1.1
Clear Status Register
The Clear Status Register command clears the status register. It functions independent
of VPP. The WSM sets and clears SR[7,6,2], but it sets bits SR[5:3,1] without clearing
them. The Status Register should be cleared before starting a command sequence to
avoid any ambiguity. A device reset also clears the Status Register.
14.2
Read Device Identifier
The Read Device Identifier command instructs the device to output manufacturer code,
device identifier code, block-lock status, protection register data, or configuration
register data (see Section 9.2, “Device Commands” on page 47 for details on issuing
the Read Device Identifier command). Table 29, “Device Identifier Information” on

The CFI Query command instructs the device to output Common Flash Interface (CFI)
data when read. See Section 9.2, “Device Commands” on page 47 for details on issuing
the CFI Query command. Appendix C, “Common Flash Interface” on page 92 shows CFI
information and address offsets within the CFI database.

Appendix A Write State Machine
Figure 33 through Figure 38 show the command state transitions (Next State Table)
based on incoming commands. Only one partition can be actively programming or
erasing at a time. Each partition stays in its last read state (Read Array, Read Device
ID, CFI Query or Read Status Register) until a new command changes it. The next WSM
state does not depend on the partition’s output state.

Notes:
1.
"Illegal commands" include commands outside of the allowed command set (allowed commands: 40H
[pgm], 20H [erase], etc.)
2.
3.
4.
If a "Read Array" is attempted from a busy partition, the result will be invalid data. The ID and Query
data are located at different locations in the address map.
1st and 2nd cycles of "2 cycles write commands" must be given to the same partition address, or
unexpected results will occur.
To protect memory contents against erroneous command sequences, there are specific instances in a
multi-cycle command sequence in which the second cycle will be ignored. For example, when the device
is program suspended and an erase setup command (0x20) is given followed by a confirm/resume
command (0xD0), the second command will be ignored because it is unclear whether the user intends
to erase the block or resume the program operation.

5.
The Clear Status command only clears the error bits in the status register if the device is not in the
following modes: WSM running (Pgm Busy, Erase Busy, Pgm Busy In Erase Suspend, OTP Busy, BEFP
modes).
6.
7.
BEFP writes are only allowed when the status register bit #0 = 0, or else the data is ignored.
The "current state" is that of the "chip" and not of the "partition"; Each partition "remembers" which
output (Array, ID/CFI or Status) it was last pointed to on the last instruction to the "chip", but the next
state of the chip does not depend on where the partition's output multiplexer (mux) is presently
pointing to.
8.
9.
Confirm commands (Lock Block, Unlock Block, Lock-Down Block, Configuration Register) perform the
operation and then move to the Ready State.
WA0 refers to the block address latched during the first write cycle of the current operation.

Appendix C Common Flash Interface
The Common Flash Interface (CFI) is part of an overall specification for multiple
command-set and control-interface descriptions. This appendix describes the database
structure containing the data returned by a read operation after issuing the CFI Query
command (see Section 9.2, “Device Commands” on page 47). System software can
parse this database structure to obtain information about the flash device, such as
block size, density, bus width, and electrical specifications. The system software will
then know which command set(s) to use to properly perform flash writes, block erases,
reads and otherwise control the flash device.
C.1
Query Structure Output
The Query database allows system software to obtain information for controlling the
flash device. This section describes the device’s CFI-compliant interface that allows
access to Query data.
Query data are presented on the lowest-order data outputs (DQ7-0) only. The numerical
offset value is the address relative to the maximum bus width supported by the device.
On this family of devices, the Query table device starting address is a 10h, which is a
word address for x16 devices.
For a word-wide (x16) device, the first two Query-structure bytes, ASCII “Q” and “R,”
appear on the low byte at word addresses 10h and 11h. This CFI-compliant device
outputs 00h data on upper bytes. The device outputs ASCII “Q” in the low byte (DQ7-0
and 00h in the high byte (DQ15-8).
)
At Query addresses containing two or more bytes of information, the least significant
data byte is presented at the lower address, and the most significant data byte is
presented at the higher address.
In all of the following tables, addresses and data are represented in hexadecimal
notation, so the “h” suffix has been dropped. In addition, since the upper byte of word-
wide devices is always “00h,” the leading “00” has been dropped from the table
notation and only the lower byte value is shown. Any x16 device outputs have 00h on
the upper byte in this mode.
