Product Description
The Serial Quad I/O™ (SQI™) family of flash-memory
devices features a six-wire, 4-bit I/O interface that
allows for low-power, high-performance operation in a
low pin-count package. SST26VF064B/064BA also
support full command-set compatibility to traditional
Serial Peripheral Interface (SPI) protocol. System
designs using SQI flash devices occupy less board
space and ultimately lower system costs.
All members of the 26 Series, SQI family are manufactured with proprietary, high-performance CMOS SuperFlash® technology. The split-gate cell design and thickoxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.
The SST26VF064B/064BA significantly improve performance and reliability, while lowering power consumption. These devices write (Program or Erase) with
a single power supply of 2.7-3.6V. The total energy
consumed is a function of the applied voltage, current,
and time of application. Since for any given voltage
range, the SuperFlash technology uses less current to
program and has a shorter erase time, the total energy
consumed during any Erase or Program operation is
less than alternative flash memory technologies.
SST26VF064B/064BA are offered in 8-contact WSON
(6 mm x 5 mm), 8-lead SOIC (200 mil), 16-lead SOIC
(300 mil), and 24-ball TBGA. See Figure 2-2 for pin
assignments.
Two configurations are available upon order:
SST26VF064B default at power-up has the WP# and
Hold# pins enabled and SST26VF064BA default at
power-up has the WP# and Hold# pins disabled.

DEVICE OPERATION
SST26VF064B/064BA support both Serial Peripheral
Interface (SPI) bus protocol and a 4-bit multiplexed SQI
bus protocol. To provide backward compatibility to traditional SPI Serial Flash devices, the device’s initial
state after a power-on reset is SPI mode which supports multi-I/O (x1/x2/x4) Read/Write commands. A
command instruction configures the device to SQI
mode. The dataflow in the SQI mode is similar to the
SPI mode, except it uses four multiplexed I/O signals
for command, address, and data sequence.
bus master is in stand-by mode and no data is being
transferred. The SCK signal is low for Mode 0 and SCK
signal is high for Mode 3. For both modes, the Serial
Data I/O (SIO[3:0]) is sampled at the rising edge of the
SCK clock signal for input, and driven after the falling
edge of the SCK clock signal for output. The traditional
SPI protocol uses separate input (SI) and output (SO)
data signals as shown in Figure 4-1. The SQI protocol
uses four multiplexed signals, SIO[3:0], for both data in
and data out, as shown in Figure 4-2. This means the
SQI protocol quadruples the traditional bus transfer
speed at the same clock frequency, without the need
for more pins on the package.
SQI Flash Memory supports both Mode 0 (0,0) and
Mode 3 (1,1) bus operations. The difference between
the two modes is the state of the SCK signal when the

Device Protection
4.1.1
SST26VF064B/064BA offer a flexible memory protection scheme that allows the protection state of each
individual block to be controlled separately. In addition,
the Write-Protection Lock-Down register prevents any
change of the lock status during device operation. To
avoid inadvertent writes during power-up, the device is
write-protected by default after a power-on reset cycle.
A Global Block-Protection Unlock command offers a
single command cycle that unlocks the entire memory
array for faster manufacturing throughput.
For extra protection, there is an additional non-volatile
register that can permanently write-protect the BlockProtection register bits for each individual block. Each
of the corresponding lock-down bits are one time programmable (OTP)—once written, they cannot be
erased. Data that had been previously programmed
into these blocks cannot be altered by programming or
erase and is not reversible
DS25119C-page 6
INDIVIDUAL BLOCK PROTECTION
SST26VF064B/064BA have a Block-Protection register which provides a software mechanism to write-lock
the individual memory blocks and write-lock, and/or
read-lock, the individual parameter blocks. The BlockProtection register is 144 bits wide: two bits each for the
eight 8 KByte parameter blocks (write-lock and readlock), and one bit each for the remaining 32 KByte and
64 KByte overlay blocks (write-lock). See Table 5-6 for
address range protected per register bit.
Each bit in the Block-Protection register (BPR) can be
written to a ‘1’ (protected) or ‘0’ (unprotected). For the
parameter blocks, the most significant bit is for readlock, and the least significant bit is for write-lock. Readlocking the parameter blocks provides additional security for sensitive data after retrieval (e.g., after initial
boot). If a block is read-locked all reads to the block
return data 00H.

 2013 Microchip Technology Inc.
SST26VF064B / SST26VF064BA
The Write Block-Protection Register command is a
two-cycle command which requires that Write-Enable
(WREN) is executed prior to the Write Block-Protection
Register command. The Global Block-Protection
Unlock command clears all write protection bits in the
Block-Protection register.
4.1.2
WRITE-PROTECTION LOCK-DOWN
(VOLATILE)
To prevent changes to the Block-Protection register,
use the Lock-Down Block-Protection Register (LBPR)
command to enable Write-Protection Lock-Down.
Once Write-Protection Lock-Down is enabled, the
Block-Protection register can not be changed. To avoid
inadvertent lock down, the WREN command must be
executed prior to the LBPR command.
To reset Write-Protection Lock-Down, performing a power
cycle on the device is required. The Write-Protection
Lock-Down status may be read from the Status register.
4.1.3
WRITE-LOCK LOCK-DOWN (NONVOLATILE)
The non-Volatile Write-Lock Lock-Down register is an
alternate register that permanently prevents changes
to the block-protect bits. The non-Volatile Write-Lock
Lock-Down register (nVWLDR) is 136 bits wide per
device: one bit each for the eight 8-KByte parameter
blocks, and one bit each for the remaining 32 KByte
and 64 KByte overlay blocks. See Table 5-6 for address
range protected per register bit.
Writing ‘1’ to any or all of the nVWLDR bits disables the
change mechanism for the corresponding Write-Lock
bit in the BPR, and permanently sets this bit to a ‘1’
(protected) state. After this change, both bits will be set
to ‘1’, regardless of the data entered in subsequent
writes to either the nVWLDR or the BPR. Subsequent
writes to the nVWLDR can only alter available locations
that have not been previously written to a ‘1’. This
method provides write-protection for the corresponding
memory-array block by protecting it from future program or erase operations.
 2013 Microchip Technology Inc.
Writing a ‘0’ in any location in the nVWLDR has no
effect on either the nVWLDR or the corresponding
Write-Lock bit in the BPR.
Note that if the Block-Protection register had been previously locked down, see “Write-Protection Lock-Down
(Volatile)”, the device must be power cycled before
using the nVWLDR. If the Block-Protection register is
locked down and the Write nVWLDR command is
accessed, the command will be ignored.
4.2
Hardware Write Protection
The hardware Write Protection pin (WP#) is used in
conjunction with the WPEN and IOC bits in the configuration register to prohibit write operations to the BlockProtection and Configuration registers. The WP# pin
function only works in SPI single-bit and dual-bit read
mode when the IOC bit in the configuration register is
set to ‘0’.
The WP# pin function is disabled when the WPEN bit
in the configuration register is ‘0’. This allows installation of the SST26VF064B/064BA in a system with a
grounded WP# pin while still enabling Write to the
Block-Protection register. The Lock-Down function of
the Block-Protection Register supersedes the WP# pin,
see Table 4-1 for Write Protection Lock-Down states.
The factory default setting at power-up of the WPEN bit
is ‘0’, disabling the Write Protect function of the WP#
after power-up. WPEN is a non-volatile bit; once the bit
is set to ‘1’, the Write Protect function of the WP# pin
continues to be enabled after power-up. The WP# pin
only protects the Block-Protection Register and Configuration Register from changes. Therefore, if the WP#
pin is set to low before or after a Program or Erase
command, or while an internal Write is in progress, it
will have no effect on the Write command.
The IOC bit takes priority over the WPEN bit in the configuration register. When the IOC bit is ‘1’, the function
of the WP# pin is disabled and the WPEN bit serves no
function. When the IOC bit is ‘0’ and WPEN is ‘1’, setting the WP# pin active low prohibits Write operations
to the Block Protection Register.

4.3
Security ID
SST26VF064B/064BA offer a 2 KByte Security ID (Sec
ID) feature. The Security ID space is divided into two
parts – one factory-programmed, 64-bit segment and
one user-programmable segment. The factory-programmed segment is programmed during manufacturing with a unique number and cannot be changed. The
user-programmable segment is left unprogrammed for
the customer to program as desired.
Use the Program Security ID (PSID) command to program the Security ID using the address shown in Table
5-5. The Security ID can be locked using the Lockout
Security ID (LSID) command. This prevents any future
write operations to the Security ID.
The factory-programmed portion of the Security ID
can’t be programmed by the user; neither the factoryprogrammed nor user-programmable areas can be
erased.
4.4
Hold Operation
The HOLD# pin pauses active serial sequences without resetting the clocking sequence. This pin is active
after every power up and only operates during SPI
single-bit and dual-bit modes. Two factory configurations are available: SST26VF064B ships with the IOC
bit set to ‘0’ and the HOLD# pin function enabled;
SST26VF064BA ships with the IOC bit set to ‘1’ and the
HOLD# pin function disabled. The HOLD# pin is always
disabled in SQI mode and only works in SPI single-bit
and dual-bit read mode.
To activate the Hold mode, CE# must be in active low
state. The Hold mode begins when the SCK active low
state coincides with the falling edge of the HOLD# signal. The Hold mode ends when the HOLD# signal’s rising edge coincides with the SCK active low state.
If the falling edge of the HOLD# signal does not coincide with the SCK active low state, then the device
enters Hold mode when the SCK next reaches the
active low state. Similarly, if the rising edge of the
HOLD# signal does not coincide with the SCK active
low state, then the device exits Hold mode when the
SCK next reaches the active low state. See Figure 4-3.
Once the device enters Hold mode, SO will be in high
impedance state while SI and SCK can be VIL or VIH.
If CE# is driven active high during a Hold condition, it
resets the internal logic of the device. As long as
HOLD# signal is low, the memory remains in the Hold
condition. To resume communication with the device,
HOLD# must be driven active high, and CE# must be
driven active low.

WPLD bit is reset to ‘0’.
4.5.5
SECURITY ID STATUS (SEC)
The Security ID Status (SEC) bit indicates when the
Security ID space is locked to prevent a Write command. The SEC is ‘1’ after the host issues a Lockout
SID command. Once the host issues a Lockout SID
command, the SEC bit can never be reset to ‘0.’
4.5.6
BUSY
The Busy bit determines whether there is an internal
Erase or Program operation in progress. If the BUSY
bit is ‘1’, the device is busy with an internal Erase or
Program operation. If the bit is ‘0’, no Erase or Program
operation is in progress.

I/O CONFIGURATION (IOC)
The I/O Configuration (IOC) bit re-configures the I/O
pins. The IOC bit is set by writing a ‘1’ to Bit 1 of the
Configuration register. When IOC bit is ‘0’ the WP# pin
and HOLD# pin are enabled (SPI or Dual Configuration
setup). When IOC bit is set to ‘1’ the SIO2 pin and SIO3
pin are enabled (SPI Quad I/O Configuration setup).
The IOC bit must be set to ‘1’ before issuing the following SPI commands: SQOR (6BH), SQIOR (EBH),
RBSPI (ECH), and SPI Quad page program (32H).
Without setting the IOC bit to ‘1’, those SPI commands
are not valid. The I/O configuration bit does not apply
when in SQI mode. The default at power-up for
SST26VF064B is ‘0’ and for SST26VF064BA is ‘1’.
4.5.9
BLOCK-PROTECTION VOLATILITY
STATE (BPNV)
The Block-Protection Volatility State bit indicates
whether any block has been permanently locked with
the nVWLDR. When no bits in the nVWLDR have been
set, the BPNV is ‘1’; this is the default state from the
factory. When one or more bits in the nVWLDR are set
to ‘1’, the BPNV bit will also be ‘0’ from that point forward, even after power-up.
4.5.10
WRITE-PROTECT ENABLE (WPEN)
The Write-Protect Enable (WPEN) bit is a non-volatile
bit that enables the WP# pin.
The Write-Protect (WP#) pin and the Write-Protect
Enable (WPEN) bit control the programmable hardware write-protect feature. Setting the WP# pin to low,
and the WPEN bit to ‘1’, enables Hardware write-protection. To disable Hardware write protection, set either
the WP# pin to high or the WPEN bit to ‘0’. There is

5.1
No Operation (NOP)
The Reset operation requires the Reset-Enable command followed by the Reset command. Any command
other than the Reset command after the Reset-Enable
command will disable the Reset-Enable.
The No Operation command only cancels a Reset
Enable command. NOP has no impact on any other
command.
5.2
Once the Reset-Enable and Reset commands are successfully executed, the device returns to normal operation Read mode and then does the following: resets the
protocol to SPI mode, resets the burst length to 8
Bytes, clears all the bits, except for bit 4 (WPLD) and
bit 5 (SEC), in the Status register to their default states,
and clears bit 1 (IOC) in the configuration register to its
default state. A device reset during an active Program
or Erase operation aborts the operation, which can
cause the data of the targeted address range to be corrupted or lost. Depending on the prior operation, the
reset timing may vary. Recovery from a Write operation
requires more latency time than recovery from other
operations. See Table 8-2 on page 48 for Rest timing
parameters.
Reset-Enable (RSTEN) and Reset
(RST)
The Reset operation is used as a system (software)
reset that puts the device in normal operating Ready
mode. This operation consists of two commands:
Reset-Enable (RSTEN) followed by Reset (RST).
To reset the SST26VF064B/064BA, the host drives
CE# low, sends the Reset-Enable command (66H),
and drives CE# high. Next, the host drives CE# low
again, sends the Reset command (99H), and drives
CE# high, see Figure 5-1.

cycle by driving CE# low, then sending the four-bits
input for address A[23:0], followed by the Set Mode
configuration bits M[7:0], and two dummy cycles. After
the two dummy cycles, the device outputs the data
starting from the specified address location. There are
no restrictions on address location access.
After the dummy cycles, the device outputs data on the
falling edge of the SCK signal starting from the specified address location. The device continually streams
data output through all addresses until terminated by a
low-to-high transition on CE#. The internal address
pointer automatically increments until the highest memory address is reached, at which point the address
pointer returns to address location 000000H. During
this operation, blocks that are Read-locked will output
data 00H.
When M[7:0] is any value other than AXH, the device
expects the next instruction initiated to be a command
instruction. To reset/exit the Set Mode configuration,
execute the Reset Quad I/O command, FFH. While in
the Set Mode configuration, the RSTQIO command will
only return the device to a state where it can accept

SPI Quad I/O Read
The SPI Quad I/O Read (SQIOR) instruction supports
up to 104 MHz frequency. SST26VF064B requires the
IOC bit in the configuration register to be set to ‘1’ prior
to executing the command. Initiate SQIOR by executing an 8-bit command, EBH. The device then switches
to 4-bit I/O mode for address bits A[23-0], followed by
the Set Mode configuration bits M[7:0], and two dummy
bytes.CE# must remain active low for the duration of
the SPI Quad I/O Read. See Figure 5-9 for the SPI
Quad I/O Read sequence.
The Set Mode Configuration bit M[7:0] indicates if the
next instruction cycle is another SPI Quad I/O Read
command. When M[7:0] = AXH, the device expects the
next continuous instruction to be another Read command, EBH, and does not require the op-code to be
entered again. The host may set the next SQIOR cycle
by driving CE# low, then sending the four-bit wide input
for address A[23:0], followed by the Set Mode configuration bits M[7:0], and two dummy cycles. After the two
dummy cycles, the device outputs the data starting
from the specified address location. There are no
restrictions on address location access.
Following the dummy bytes, the device outputs data
from the specified address location. The device continually streams data output through all addresses until
terminated by a low-to-high transition on CE#. The
internal address pointer automatically increments until
the highest memory address is reached, at which point
the address pointer returns to the beginning of the

When M[7:0] is any value other than AXH, the device
expects the next instruction initiated to be a command
instruction. To reset/exit the Set Mode configuration,
execute the Reset Quad I/O command, FFH. See Figure 5-10 for the SPI Quad I/O Mode Read sequence

SQI Read Burst with Wrap (RBSQI)
SQI Read Burst with wrap is similar to High Speed
Read in SQI mode, except data will output continuously
within the burst length until a low-to-high transition on
CE#. To execute a SQI Read Burst operation, drive
CE# low then send the Read Burst command cycle
(0CH), followed by three address cycles, and then
three dummy cycles. Each cycle is two nibbles (clocks)
long, most significant nibble first.
After the dummy cycles, the device outputs data on the
falling edge of the SCK signal starting from the specified address location. The data output stream is continuous through all addresses until terminated by a low-tohigh transition on CE#.
During RBSQI, the internal address pointer automatically increments until the last byte of the burst is
reached, then it wraps around to the first byte of the
burst. All bursts are aligned to addresses within the
burst length, see Table 5-3. For example, if the burst
length is eight Bytes, and the start address is 06h, the
burst sequence would be: 06h, 07h, 00h, 01h, 02h,
03h, 04h, 05h, 06h, etc. The pattern repeats until the
command is terminated by a low-to-high transition on
CE#.
During this operation, blocks that are Read-locked will
output data 00H.

SPI Dual-Output Read
Following the dummy byte, the SST26VF064B/064BA
outputs data from SIO[1:0] starting from the specified
address location. The device continually streams data
output through all addresses until terminated by a lowto-high transition on CE#. The internal address pointer
automatically increments until the highest memory
address is reached, at which point the address pointer
returns to the beginning of the address space.
The SPI Dual-Output Read instruction supports up to
104 MHz frequency. Initiate SPI Dual-Output Read by
executing an 8-bit command, 3BH, followed by address
bits A[23-0] and a dummy byte. CE# must remain
active low for the duration of the SPI Dual-Output Read
operation. See Figure 5-13 for the SPI Quad Output
Read sequence.

SPI Dual I/O Read
The SPI Dual I/O Read (SDIOR) instruction supports
up to 80 MHz frequency. Initiate SDIOR by executing
an 8-bit command, BBH. The device then switches to
2-bit I/O mode for address bits A[23-0], followed by the
Set Mode configuration bits M[7:0], and two dummy
bytes.CE# must remain active low for the duration of
the SPI Dual I/O Read. See Figure 5-14 for the SPI
Dual I/O Read sequence.
When M[7:0] is any value other than AXH, the device
expects the next instruction initiated to be a command
instruction. To reset/exit the Set Mode configuration,
execute the Reset Quad I/O command, FFH. See Figure 5-15 for the SPI Dual I/O Read sequence when
M[7:0] = AXH.
Following the dummy bytes, the SST26VF064B/064BA
outputs data from the specified address location. The
device continually streams data output through all
addresses until terminated by a low-to-high transition
on CE#. The internal address pointer automatically
increments until the highest memory address is
reached, at which point the address pointer returns to
the beginning of the address space.
The Set Mode Configuration bit M[7:0] indicates if the
next instruction cycle is another SPI Dual I/O Read
command. When M[7:0] = AXH, the device expects the
next continuous instruction to be another SDIOR command, BBH, and does not require the op-code to be
entered again. The host may set the next SDIOR cycle
by driving CE# low, then sending the two-bit wide input
for address A[23:0], followed by the Set Mode configuration bits M[7:0], and two dummy cycles. After the two
dummy cycles, the device outputs the data starting
from the specified address location. There are no
restrictions on address location access.

Write-Suspend and Write-Resume
Write-Suspend allows the interruption of Sector-Erase,
Block-Erase, SPI Quad Page-Program, or Page-Program operations in order to erase, program, or read
data in another portion of memory. The original operation can be continued with the Write-Resume command. This operation is supported in both SQI and SPI
protocols.
Only one write operation can be suspended at a time;
if an operation is already suspended, the device will
ignore the Write-Suspend command. Write-Suspend
during Chip-Erase is ignored; Chip-Erase is not a valid
command while a write is suspended. The WriteResume command is ignored until any write operation
(Program or Erase) initiated during the Write-Suspend
is complete. The device requires a minimum of 500 µs
between each Write-Suspend command.
DS25119C-page 28
5.23
Write-Suspend During SectorErase or Block-Erase
Issuing a Write-Suspend instruction during SectorErase or Block-Erase allows the host to program or
read any sector that was not being erased. The device
will ignore any programming commands pointing to the
suspended sector(s). Any attempt to read from the suspended sector(s) will output unknown data because the
Sector- or Block-Erase will be incomplete.
To execute a Write-Suspend operation, the host drives
CE# low, sends the Write Suspend command cycle
(B0H), then drives CE# high. The Status register indicates that the erase has been suspended by changing
the WSE bit from ‘0’ to ‘1,’ but the device will not accept
another command until it is ready. To determine when
the device will accept a new command, poll the BUSY
bit in the Status register or wait TWS.

Programming
Issuing a Write-Suspend instruction during Page Programming allows the host to erase or read any sector
that is not being programmed. Erase commands pointing to the suspended sector(s) will be ignored. Any
attempt to read from the suspended page will output
unknown data because the program will be incomplete.
To execute a Write Suspend operation, the host drives
CE# low, sends the Write Suspend command cycle
(B0H), then drives CE# high. The Status register indicates that the programming has been suspended by
changing the WSP bit from ‘0’ to ‘1,’ but the device will
not accept another command until it is ready. To determine when the device will accept a new command, poll
the BUSY bit in the Status register or wait TWS.
5.25
Write-Resume
Write-Resume restarts a Write command that was suspended, and changes the suspend status bit in the Status register (WSE or WSP) back to ‘0’.
To execute a Write-Resume operation, the host drives
CE# low, sends the Write Resume command cycle
(30H), then drives CE# high. To determine if the internal, self-timed Write operation completed, poll the
BUSY bit in the Status register, or wait the specified
time TSE, TBE or TPP for Sector-Erase, Block-Erase, or
Page-Programming, respectively. The total write time
before suspend and after resume will not exceed the
uninterrupted write times TSE, TBE or TPP.

Read Security ID
The Read Security ID operation is supported in both
SPI and SQI modes. To execute a Read Security ID
(SID) operation in SPI mode, the host drives CE# low,
sends the Read Security ID command cycle (88H), two
address cycles, and then one dummy cycle. To execute
TABLE 5-5:
a Read Security ID operation in SQI mode, the host
drives CE# low and then sends the Read Security ID
command, two address cycles, and three dummy
cycles.
After the dummy cycles, the device outputs data on the
falling edge of the SCK signal, starting from the specified address location. The data output stream is continuous through all SID addresses until terminated by a
low-to-high transition on CE#. See Table 5-5 for the
Security ID address range.
5.27
Program Security ID
The Program Security ID instruction programs one to
2040 Bytes of data in the user-programmable, Security
ID space. This Security ID space is one-time programmable (OTP). The device ignores a Program Security
ID instruction pointing to an invalid or protected
address, see Table 5-5. Prior to the program operation,
execute WREN.
To execute a Program SID operation, the host drives
CE# low, sends the Program Security ID command
cycle (A5H), two address cycles, the data to be programmed, then drives CE# high. The programmed data
must be between 1 to 256 Bytes and in whole Byte
increments.
The device handles shifting of more than 256 Bytes of
data by maintaining the last 256 Bytes of data as the
correct data to be programmed. If the target address for
the Program Security ID instruction is not the beginning
of the page boundary, and the number of data input
exceeds or overlaps the end of the address of the page
boundary, the excess data inputs wrap around and will
be programmed at the start of that target page.
The Program Security ID operation is supported in both
SPI and SQI mode. To determine the completion of the
internal, self-timed Program SID operation, poll the

Lockout Security ID
mands function in both SPI and SQI modes. The Status
register may be read at any time, even during a Write
operation. When a Write is in progress, poll the BUSY
bit before sending any new commands to assure that
the new commands are properly received by the
device.
The Lockout Security ID instruction prevents any future
changes to the Security ID, and is supported in both
SPI and SQI modes. Prior to the operation, execute
WREN.
To execute a Lockout SID, the host drives CE# low,
sends the Lockout Security ID command cycle (85H),
then drives CE# high. Poll the BUSY bit in the software
status register, or wait TPSID, for the completion of the
Lockout Security ID operation.
5.29
To Read the Status or Configuration registers, the host
drives CE# low, then sends the Read-Status-Register
command cycle (05H) or the Read Configuration Register command (35H). A dummy cycle is required in
SQI mode. Immediately after the command cycle, the
device outputs data on the falling edge of the SCK signal. The data output stream continues until terminated
by a low-to-high transition on CE#. See Figures 5-28
and 5-29 for the instruction sequence.

After the command cycle, the device outputs data on
the falling edge of the SCK signal starting with the most
significant bit(s), see Table 5-6 for definitions of each bit
in the Block-Protection register. The RBPR command
does not wrap around. After all data has been output,
the device will output 0H until terminated by a low-tohigh transition on CE#. Figures 5-36 and 5-37.
The Read Block-Protection Register instruction outputs
the Block-Protection register data which determines
the protection status. To execute a Read Block-Protection Register operation, the host drives CE# low, and

Power-Up Specifications
All functionalities and DC specifications are specified
for a VDD ramp rate of greater than 1V per 100 ms (0V
to 3.0V in less than 300 ms). See Table 6-3 and Figure
6-1 for more information.
TABLE 6-3:
When VDD drops from the operating voltage to below
the minimum VDD threshold at power-down, all operations are disabled and the device does not respond to
commands. Data corruption may result if a power-down
occurs while a Write-Registers, program, or erase
operation is in progress. See Figure 6-2.

Mapping Guidance Details
The SFDP Memory Organization/Block Protection Bit
Mapping defines the memory organization including
uniform sector/block sizes and different contiguous
sectors/blocks sizes. In addition, this bit defines the
TABLE 11-2:
Major Section X
number of these uniform and different sectors/blocks
from address 000000H to the full range of Memory and
the associated Block Locking Register bits of each sector/block.
Each major Section is defined as follows:
SECTION DEFINITION
Section X: Sector Type Number
Section X: Number of Sectors
Section X: Block-Protection Register Bit Start Location
Section X: Block-Protection Register Bit End Location
A Major Section consists of Sector Type Number, Number of Sector of this type, and the Block-Protection Bit
Start/End locations. This is tied directly to JEDEC Flash
Parameter Table Sector Size Type (in 7th DWORD and
8th DWORD section). Note that the contiguous 4KByte
Sectors across the full memory range are not included
on this section because they are not defined in the
JEDEC Flash Parameter Table Sector Size Type section. Only the sectors/blocks that are dependently tied
with the Block-Protection Register bits are defined. A
major section is a partition of contiguous same-size
sectors/blocks. There will be several Major Sections as
you dissect across memory from 000000h to the full
range. Similar sector/block size that re-appear may be
defined as a different Major Section.
11.1.1
BLOCK-PROTECTION REGISTER
BIT START LOCATION (BPSL)
Block-Protection Register Bit Start Location (BPSL)
designates the start bit location in the Block-Protection
Register where the first sector/block of this Major Section begins. If the value of BPSL is 00H, this location is
the 0 bit location. If the value is other than 0, then this
value is a constant value adder (c) for a given formula,
(2m + 1) + (c). See “Memory Configuration”.
From the initial location, there will be a bit location for
every increment by 1 until it reaches the Block Protection Register Bit End Location (BPEL). This number
range from BPSL to BPEL will correspond to, and be
equal to, the number of sectors/blocks on this Major
Section.
SECTOR TYPE NUMBER
Sector Type Number is the sector/block size typed
defined in JEDEC Flash Parameter Table: SFDP
address locations 4CH, 4EH, and 50H. For SFDP
address location 4CH, which is Sector Type 1, the size
is represented by 01H; SFDP address location 4EH,
Sector Type 2, size is represented by 02H; SFDP
address location 50H, Sector Type 3, size is represented by 03H; and SFDP address location 52H, Sector Type 4, size is represented by 04H. Contiguous
Same Sector Type # Size can re-emerge across the
memory range and this Sector Type # will indicate that
it is a separate/independent Major Section from the
previous contiguous sectors/blocks.
11.1.2
11.1.3
NUMBER OF SECTORS
Number of Sectors represents the number of contiguous sectors/blocks with similar size. A formula calculates the contiguous sectors/blocks with similar size.
Given the sector/block size, type, and the number of
sectors, the address range of these sectors/blocks can
be determined along with specific Block Locking Register bits that control the read/write protection of each
sectors/blocks.
DS25119C-page 70
11.1.4
BLOCK PROTECTION REGISTER
BIT END LOCATION (BPEL)
Block Protection Register Bit End Location designates
the end bit location in the Block Protection Register bit
where the last sector/block of this Major Section ends.
The value in this field is a constant value adder (c) for
a given formula or equation, (2m + 1) + (c). See “Memory Configuration”
11.1.5
MEMORY CONFIGURATION
For the SST26VF064B/064BA family, the memory configuration is setup with different contiguous block sizes
from bottom to the top of the memory. For example,
starting from bottom of memory it has four 8KByte
blocks, one 32KByte block, x number of 64KByte
blocks depending on memory size, then one 32KByte
block, and four 8KByte block on the top of memory. See
Table 11-3.

Classifying these sector/block sizes via the Sector
Type derived from JEDEC Flash Parameter Table:
SFDP address locations 4CH, 4EH, and 50H is as follows:
• 8KByte Blocks are classified as Sector Type 1
(@4CH of SFDP)
• 32KByte Blocks are classified as Sector Type 2
(@4EH of SFDP)
• 64KByte Blocks are classified as Sector Type 3
(@50H of SFDP)
For the Number of Sectors associated with the contiguous sectors/blocks, a formula is used to determine the
number of sectors/blocks of these Sector Types:
• 8KByte Block (Type 1) is calculated by 2n. n is a
byte.
• 32KByte Block (Type 2) is calculated by 2n. n is a
byte.
• 64KByte Block (Type 3) is calculated by (2m - 2).
m can either be a 4, 5, 6, 7 or 8 depending on the
memory size. This m field is going to be used for
the 64KByte Block Section and will also be used
for the Block Protection Register Bit Location formula.
• 64Mbit = 7
• 128Mbit = 8
Block Protect Register Start/End Bits are mapped in the
SFDP by using the formula (2m + 1) + (c). “m” is a constant value that represents the different densities from
8Mbit to 128Mbit (used also in the formula calculating
number of 64Kbyte Blocks above). The values that are
going to be placed in the Block Protection Bit Start/End
field table are the constant value adder (c) in the formula and are represented in two’s compliment except
when the value is 00H. If the value is 00H, this location
is the 0 bit location. If the value is other than 0, then this
is a constant value adder (c) that will be used in the formula. The most significant (left most) bit indicates the
sign of the integer; it is sometimes called the sign bit.
If the sign bit is zero, then the number is greater than or
equal to zero, or positive. If the sign bit is one, then the
number is less than zero, or negative.
See Table 11-4 for an example of this formula.
m will have a constant value for specific densities and
is defined as:
• 8Mbit = 4
• 16Mbit = 5
• 32Mbit = 6
