Functional Overview
This section provides an overview of the features and capabilities of the 1-Gbit P30 Family device.
The P30 family provides density upgrades from 64-Mbit through 1-Gbit. 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 Read Configuration Register 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 1-Gbit
P30 Family supports read operations with VCC at 1.8 V, and erase and program operations with
VPP at 1.8 V or 9.0 V. Buffered Enhanced Factory Programming (BEFP) provides the fastest flash
array programming performance with VPP at 9.0 V, which increases factory throughput. With VPP
at 1.8 V, 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.
A Command User Interface (CUI) is the interface between the system processor and all internal
operations of the device. An internal Write State Machine (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 1-Gbit P30 Family’s 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 P30 device also has four pre-defined spaces in the main
array that can be configured as One-Time Programmable (OTP).

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].
See Table 5 on page 22 and Figure 10 on page 23 for 512-Mbit addressing.

Input/
Output
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.
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#

CLK
Input
Input
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.
FLASH 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.
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.
OE#
Input
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.
RST#
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.
WAIT
Output
WAIT: Indicates data valid in synchronous array or non-array burst reads. Read Configuration
Register bit 10 (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.
• 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.
WE#
Input
WRITE ENABLE: Active low input. WE# controls writes to the device. Address and data are latched
on the rising edge of WE#.
WP#
Input
WRITE PROTECT: Active low input. WP# low enables the lock-down mechanism. Blocks in lockdown 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.
VPP
Power/
Input
Set VPP = VCC 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.

Power
Device Core Power Supply: Core (logic) source voltage. Writes to the flash array are inhibited when
VCC ≤ VLKO. Operations at invalid VCC voltages should not be attempted.

Notes:
1.
Temperature for 1-Gbit SCSP is –30 °C to +85 °C.
2.
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 < 20 ns. Maximum DC voltage on VCC is VCC + 0.5 V, which, during transitions, may
overshoot to VCC + 2.0 V for periods < 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 < 20 ns.
3.
Maximum DC voltage on VPP may overshoot to +11.5 V for periods < 20 ns.
4.
Program/erase voltage is typically 1.7 V – 2.0 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.
5.
Output shorted for no more than one second. No more than one output shorted at a time.

WAIT is driven per OE# assertion during synchronous array or non-array read, and can be configured to
assert either during or one data cycle before valid data.
This diagram illustrates the case in which an n-word burst is initiated to the flash memory array and it is
terminated by CE# deassertion after the first word in the burst.

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.
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.
When doing a Read Status operation following any command that alters the Status Register, W14 is
20 ns.
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 Down
Power supply sequencing is not required if VCC, VCCQ, and VPP are connected together; If
VCCQ and/or VPP are not connected to the VCC supply, then VCC should attain VCCMIN before
applying VCCQ and VPP. Device inputs should not be driven before supply voltage equals VCCMIN.
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.

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® Multi-Level Cell (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. Highfrequency, 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 CPU provides control of all insystem read, write, and erase operations of the device via the system bus. The on-chip Write State
Machine (WSM) manages all block-erase and word-program algorithms.
Device commands are written to the Command User Interface (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 P30 device conform to standard microprocessor bus operations. Table 19
summarizes the bus operations and the logic levels that must be applied to the device control signal
inputs.

3.
RST# must be at VSS ± 0.2 V to meet the maximum specified power-down current.
9.1.1
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 53 for details on the available read modes, and see
Section 14.0, “Special Read States” on page 75 for details regarding the available read states.

9.1.2
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 20, “Command Bus Cycles” on page 50 shows the bus cycle
sequence for each of the supported device commands, while Table 21, “Command Codes and
Definitions” on page 51 describes each command. See Section 7.0, “AC Characteristics” on
page 33 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, 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 33 for details about signal-timing.

Device Commands
Device operations are initiated by writing specific device commands to the Command User
Interface (CUI). See Table 20, “Command Bus Cycles” on page 50. Several commands are used to
modify array data including Word Program and Block Erase commands. Writing either 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.

algorithm, writing the data from the buffer to the flash memory array.
First cycle of a 2-cycle command; initiates Buffered Enhanced Factory
Program mode (BEFP). The CUI then waits for the BEFP Confirm command,
BEFP Setup
0xD0, that initiates the BEFP algorithm. All other commands are ignored when
BEFP mode begins.
If the previous command was BEFP Setup (0x80), the CUI latches the address
BEFP Confirm
and data, and prepares the device for BEFP mode.
First cycle of a 2-cycle command; prepares the CUI for a block-erase
operation. The WSM performs the erase algorithm on the block addressed by
Block Erase Setup
the Erase Confirm command. If the next command is not the Erase Confirm
(0xD0) command, the CUI sets Status Register bits SR[4] and SR[5], and
places the device in read status register mode.
If the first command was Block Erase Setup (0x20), the CUI latches the
address and data, and the WSM erases the addressed block. During blockerase operations, the device responds only to Read Status Register and Erase
Block Erase Confirm
Suspend commands. CE# or OE# must be toggled to update the Status
Register in asynchronous read. CE# or ADV# must be toggled to update the
Status Register Data for synchronous Non-array reads
This command issued to any device address initiates a suspend of the
currently-executing program or block erase operation. The Status Register
Program or Erase
indicates successful suspend operation by setting either SR[2] (program
Suspend

State Machine remains in the suspend mode regardless of control signal states
(except for RST# asserted).
This command issued to any device address resumes the suspended program

First cycle of a 2-cycle command; prepares the CUI for block lock configuration
changes. If the next command is not Block Lock (0x01), Block Unlock (0xD0),
Lock Block Setup
or Block Lock-Down (0x2F), the CUI sets Status Register bits SR[4] and SR[5],
indicating a command sequence error.
If the previous command was Block Lock Setup (0x60), the addressed block is

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 Read
Configuration Register must be configured to enable synchronous burst reads of the flash memory
array (see Section 10.3, “Read Configuration Register” on page 54).
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. To change the read state,
the appropriate read command must be written to the device (see Section 9.2, “Device Commands”
on page 50). See Section 14.0, “Special Read States” on page 75 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. 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 Read Configuration Register bit
RCR[15] is set (see Section 10.3, “Read Configuration Register” on page 54).
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 33).
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 55). 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 19, “Synchronous Single-Word Array or Non-array Read Timing” on page 39

• Figure 21, “Synchronous Burst-Mode Four-Word Read Timing” on page 41
10.3
Read Configuration Register
The Read Configuration Register (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 50).
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 76).
The RCR is shown in Table 22. 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.
10.3.2
Latency Count
The Latency Count bits, LC[2:0], 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 data
word is to be driven onto DQ[15:0]. The input clock frequency is used to determine this value.
Figure 28 shows the data output latency for the different settings of LC[2:0].
Synchronous burst with a Latency Count setting of Code 4 will result in zero WAIT state; however,
a Latency Count setting of Code 5 will cause 1 WAIT state (Code 6 will cause 2 WAIT states, and
Code 7 will cause 3 WAIT states) after every four words, regardless of whether a 16-word
boundary is crossed. If RCR[9] (Data Hold) bit is set (data hold of two clocks) this WAIT condition
will not occur because enough clocks elapse during each burst cycle to eliminate subsequent WAIT
states.
Refer to Table 23, “LC and Frequency Support” on page 56 for Latency Code Settings.

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
17, “Asynchronous Single-Word Read (ADV# Latch)” on page 38, and Figure 18, “Asynchronous
Page-Mode Read Timing” on page 39.

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 30). 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 Data Hold 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.

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 25 shows the synchronous burst sequence for all burst lengths, as well as the
effect of the Burst Wrap (BW) setting.

Clock Edge
The Clock Edge (CE) bit selects either a rising (default) or falling clock edge for CLK. This clock
edge is used at the start of a burst cycle, to output synchronous data, and to assert/deassert WAIT.
10.3.8
Burst Wrap
The Burst Wrap (BW) bit determines whether 4-word, 8-word, or 16-word burst length accesses
wrap within the selected word-length boundaries or cross word-length boundaries. When BW is
set, burst wrapping does not occur (default). When BW is cleared, burst wrapping occurs.
When performing synchronous burst reads with BW set (no wrap), an output delay may occur
when the burst sequence crosses its first device-row (16-word) boundary. If the burst sequence’s
start address is 4-word aligned, then no delay occurs. If the start address is at the end of a 4-word

boundary, the worst case output delay is one clock cycle less than the first access Latency Count.
This delay can take place only once, and doesn’t occur if the burst sequence does not cross a
device-row boundary. WAIT informs the system of this delay when it occurs.
10.3.9
Burst Length
The Burst Length bit (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 25, “Burst Sequence Word Ordering” on page 59). When a burst cycle begins, the device
outputs synchronous burst data until it reaches the end of the “burstable” address space.

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 48 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 69 for details on locking
and unlocking blocks.
The Intel StrataFlash® Embedded Memory (P30) is segmented into multiple Programming
Regions. Programming Regions are made up of 8 or 16 blocks depending on the density. The 64and 128-Mbit devices have 8 blocks per Programming Region, while the 256-Mbit has 16 blocks in
each Programming Region (see Table 26). See Section 4.4, “Memory Maps” on page 24 for
address ranges of each Programming Region per density.

Execute in Place (XIP) is defined as the ability to execute code directly from the flash memory.
XIP applications must partition the memory such that code and data are in separate programming
regions (see Table 26, “Programming Regions per Device” on page 61). Each Programming
Region should contain only code or data, and 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 P30 device.
11.1
Code :
Execution code ran out of the flash device on a continuous basis in the system.
Data :
Information periodically programmed into the flash device and read back (e.g.
execution code shadowed and executed in RAM, pictures, log files, etc.).
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 48). 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 40, “Word Program Flowchart” on page 85. VPP must be above VPPLK, and within
the specified VPPL min/max values (nominally 1.8 V).

1-Gbit P30 Family
During programming, the Write State Machine (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 67).
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.
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 30 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 31, “Example VPP Supply
Connections” on page 66 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 50), 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 42, “Buffer Program Flowchart” on page 87).
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.
April 2005
62
Intel StrataFlash® Embedded Memory (P30)
Order Number: 306666, Revision: 001
Datasheet
1-Gbit P30 Family
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 Status Register bits SR[7,5,4] are set. If an error
occurs while writing to the array, the device stops programming, and Status Register bits 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 30 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 Status
Register bits SR[5,4] are set.
If Buffered programming is attempted while VPP is below VPPLK, Status Register bits 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 43, “BEFP Flowchart”
on page 88). 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 postprogram verification and its associated overhead.

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 (WA0) 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
• WA0 must align with the start of an array buffer boundary1
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
NOTES:
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.
Some degradation in performance may occur if this limit is exceeded, but the internal algorithm
continues to work properly.
3.
If the internal address counter increments beyond the block's maximum address, addressing wraps
around to the beginning of the block.
4.
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.

1-Gbit P30 Family
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.
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
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.
11.4
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 41, “Program Suspend/Resume
Flowchart” on page 86).

1-Gbit P30 Family
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 45.
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 41, “Program Suspend/Resume Flowchart” on page 86).
11.6
Program Protection
When VPP = VIL, absolute hardware write protection is provided for all device blocks. If VPP is at
or below VPPLK, programming operations halt and SR[3] is set indicating a VPP-level error. Block
lock registers are not affected by the voltage level on VPP; they may still be programmed and read,
even if VPP is less than VPPLK.

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 50). 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 44,
“Block Erase Flowchart” on page 89).
During a block erase, the Write State Machine (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 61).
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 41, “Program Suspend/Resume Flowchart” on page 86).
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 45.

1-Gbit P30 Family
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
Erase Resume
The Erase Resume command instructs the device to continue erasing, and automatically clears
status register bits 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 41, “Program Suspend/Resume Flowchart” on page 86).
12.4
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 66 and Section 12.4, “Erase Protection” on
page 68).
The P30 device also offers four pre-defined areas in the main array that can be configured as OneTime 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
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 50
and Figure 46, “Block Lock Operations Flowchart” on page 91). 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.
13.1.2
Unlock Block
The Unlock Block command is used to unlock blocks (see Section 9.2, “Device Commands” on
page 50). 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 32, “Block Locking State Diagram” on
page 70).
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 50). 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 32, “Block Locking
State Diagram” on page 70).
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 76). 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.

Hardware Locked and Locked-Down states.
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:
April 2005

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 78, which shows valid commands during an erase suspend.

Selectable One-Time Programmable Blocks
Any of four pre-defined areas from the main array (the four 32 KB parameter blocks together as
one and the three adjacent 128 KB main blocks) can be configured as One-Time Programmable

Protection Registers
The device contains 17 Protection Registers (PRs) 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 64bit 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 33, “Protection Register Map” on page 73).
The user-programmable Protection Registers contain one-time programmable (OTP) bits; when
programmed, register 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.

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 50). Next, perform a read operation
using the address offset corresponding to the register to be read. Table 29, “Device Identifier
Information” on page 77 shows the address offsets of the Protection Registers and Lock Registers.
Register data is read 16 bits at a time.
13.3.2
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 50). Next, write the desired Protection Register data to the same
Protection Register address (see Figure 33, “Protection Register Map” on page 73).

1-Gbit P30 Family
The device programs the 64-bit and 128-bit user-programmable Protection Register data 16 bits at
a time (see Figure 47, “Protection Register Programming Flowchart” on page 92). 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).
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 50). 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 77).
Bit 0 of Lock Register 0 is already programmed 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:

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 16, “Asynchronous Single-Word Read (ADV# Low)” on page 38
• Figure 17, “Asynchronous Single-Word Read (ADV# Latch)” on page 38
• Figure 19, “Synchronous Single-Word Array or Non-array Read Timing” on page 39
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. Status Register data 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. Read
Array command).
The Status Register is read using single asynchronous-mode or synchronous burst mode reads.
Status Register data 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, reading the Status Register in synchronous burst mode, CE# or ADV#
must be toggled to update status data.
The Device Write Status bit (SR[7]) provides overall status of the device. Status register bits
SR[6:1] present status and error information about the program, erase, suspend, VPP, and blocklocked 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
Write State Machine (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 50 for details on issuing the Read Device Identifier
command). Table 29, “Device Identifier Information” on page 77 and Table 30, “Device ID codes”
on page 77 show the address offsets and data values for this device.

CFI Query
The CFI Query command instructs the device to output Common Flash Interface (CFI) data when
read. See Section 9.2, “Device Commands” on page 50 for details on issuing the CFI Query
command. Appendix C, “Common Flash Interface” on page 93 shows CFI information and address
offsets within the CFI database.

Appendix A Write State Machine
Figure 34 through Figure 39 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.
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.
3.
1st and 2nd cycles of "2 cycles write commands" must be given to the same partition address, or unexpected results will
occur.
4.
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.

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).
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 mux is presently pointing to.
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 50). 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 can be assumed to have 00h on the upper byte in this mode.

Following bytes are factory or user-programmable.
bits 32–39 = “n” ∴ n = factory pgm'd groups (low byte)
bits 40–47 = “n” ∴ n = factory pgm'd groups (high byte)
bits 48–55 = “n” \ 2n = factory programmable bytes/group
bits 56–63 = “n” ∴ n = user pgm'd groups (low byte)
bits 64–71 = “n” ∴ n = user pgm'd groups (high byte)
n
bits 72–79 = “n” ∴ 2 = user programmable bytes/group

bits 0–2 “n” such that 2 HEX value represents the
maximum number of continuous synchronous reads when
the device is configured for its maximum word width. A value
of 07h indicates that the device is capable of continuous
linear bursts that will output data until the internal burst
counter reaches the end of the device’s burstable address
space. This field’s 3-bit value can be written directly to the
Read Configuration Register bits 0–2 if the device is
configured for its maximum word width. See offset 28h for
word width to determine the burst data output width.
