Notes:
1. See Table 1 for descriptions of bus operations.
2. All values are in hexadecimal.
3. Except when reading array or Automatic Select data, all bus cycles are write operation.
4. Address bits are don't care for unlock and command cycles, except when PA or SA is required.
5. No unlock or command cycles required when device is in read mode.
6. The Reset command is required to return to the read mode when the device is in the Automatic Select mode or if
Q5 goes high.
7. The fourth cycle of the Automatic Select command sequence is a read cycle.
8. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block. In the third
cycle of the command sequence, address bit A21=0 to verify sectors 0~63, A21=1 to verify sectors 64.
9. If WP protects the highest address sectors, the data is 98h for factory locked and 18h for factory. If WP protects
the lowest address sector, the data is 88h for factory locked and 08h for not factory locked.
10.The system may read and program functions in non-erasing sectors, or enter the Automatic Select mode, when in
the erase Suspend mode. The Erase Suspend command is valid only during a sector erase operation.
11.The Erase Resume command is valid only during the Erase Suspend mode.
12.Command is valid when device is ready to read array data or when device is in Automatic Select mode.
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to
retrieve data.The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The system
can read array data using the standard read timings,
except that if it reads at an address within erase-
suspended sectors, the device outputs status data. After
completing a programming operation in the Erase
Suspend mode, the system may once again read array
data with the same exception. See "Erase Suspend/Erase
Resume Commands" for more information on this mode.
The system
must issue the reset command to re-en-
able the device for reading array data if Q5 goes high, or
while in the
Automatic Select mode. See the "Reset
Command" section, next.
RESET COMMAND
Writing the reset command to the device resets the
device to reading array data. Address bits are don't care
for this command.
The reset command may be written between the se-
quence cycles in an erase command sequence before
erasing begins. This resets the device to reading array
data. Once erasure begins, however, the device ignores
reset commands until the operation is complete.
The reset command may be written between the se-
quence cycles in a program command sequence before
programming begins. This resets the device to reading
array data (also applies to programming in Erase Suspend
mode). Once programming begins, however, the device
ignores reset commands until the operation is complete.
The reset command may be written between the
sequence cycles in an SILICON ID READ command
sequence. Once in the SILICON ID READ mode, the
reset command
must be written to return to reading array
data (also applies to SILICON ID READ during Erase
Suspend).
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to reading
array data (also applies during Erase Suspend).
SILICON ID READ COMMAND SEQUENCE
The SILICON ID READ command sequence allows the
host system to access the manufacturer and devices
codes, and determine whether or not a sector is protected.
Table 2 shows the address and data requirements.
