Legend
X = Don’t care
RA = Address of the memory to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE# or CE# pulse, whichever happens later.
PD = Data to be programmed at location PA. Data latches on the rising edge of the WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits A
max
–A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same write buffer page as PA.
WC = Word Count is the number of write buffer locations to load minus 1.
Notes
1. See
Table 7.1 on page 14
for description of bus operations.
2. All values are in hexadecimal.
3. All bus cycles are write cycles unless otherwise noted.
4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles.
5. Address bits A
MAX
:A16 are don’t cares for unlock and command cycles, unless SA or PA required. (A
MAX
is the Highest Address pin.).
6. No unlock or command cycles required when reading array data.
7. The Reset command is required to return to reading array data when device is in the autoselect mode, or if DQ5 goes high (while the device is providing status
data).
8. See
Table 7.2 on page 17
for device ID values and definitions.
9. The fourth, fifth, and sixth cycles of the autoselect command sequence are read cycles.
10.The data is 00h for an unprotected sector and 01h for a protected sector. See “Autoselect Command Sequence” for more information. This is same as PPB
Status Read except that the protect and unprotect statuses are inverted here.
11.The data value for DQ7 is “1” for a serialized, protected Secured Silicon Sector region and “0” for an unserialized, unprotected region. See
Table 7.3 on page 17
for data and definitions.
12.Command is valid when device is ready to read array data or when device is in autoselect mode.
13.Command sequence returns device to reading array after being placed in a Write-to-Buffer-Abort state. Full command sequence is required if resetting out of
abort while in Unlock Bypass mode.
14.The Unlock-Bypass command is required prior to the Unlock-Bypass-Program command.
15.The Unlock-Bypass-Reset command is required to return to reading array data when the device is in the unlock bypass mode.
16.The system can read and program/program suspend in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode. The Erase
Suspend command is valid only during a sector erase operation.
17.The Erase Resume/Program Resume command is valid only during the Erase Suspend/Program Suspend modes.
18.The Exit command returns the device to reading the array.
