Description
Erase
Block erase setup
0x20
First cycle of a two-cycle command; prepares the CUI for a BLOCK
ERASE operation. The device performs the erase algorithm on the
block addressed by the ERASE CONFIRM command. If the next com-
mand is not the ERASE CONFIRM (0xD0) command, the CUI sets status
register bits SR4 and SR5, and places the device in read status register
mode.
Block erase confirm
0xD0
0xB0
If the first command was BLOCK ERASE SETUP (0x20), the CUI latches
the address and data, and the device erases the addressed block. Dur-
ing BLOCK ERASE operations, the device responds only to READ STATUS
REGISTER and ERASE 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-ar-
ray reads.
Suspend
Program or erase
suspend
This command issued to any device address initiates a suspend of the
currently-executing program or BLOCK ERASE operation. The status
register indicates successful suspend operation by setting either SR2
(program suspended) or SR6 (erase suspended), along with SR7 (ready).
The device remains in the suspend mode regardless of control signal
states (except for RST# asserted).
Suspend resume
Block lock setup
0xD0
0x60
This command issued to any device address resumes the suspended
PROGRAM or BLOCK ERASE operation.
Protection
First cycle of a two-cycle command; prepares the CUI for block lock con-
figuration changes. If the next command is not BLOCK LOCK (0x01),
BLOCK UNLOCK (0xD0), or BLOCK LOCK DOWN (0x2F), the CUI sets sta-
tus register bits SR5 and SR4, indicating a command sequence error.
Block lock
0x01
0xD0
If the previous command was BLOCK LOCK SETUP (0x60), the addressed
block is locked.
Block unlock
If the previous command was BLOCK LOCK SETUP (0x60), the addressed
block is unlocked. If the addressed block is in a lock down state, the op-
eration has no effect.
Block lock down
0x2F
0xC0
If the previous command was BLOCK LOCK SETUP (0x60), the addressed
block is locked down.
OTP register or lock
register program set-
up
First cycle of a two-cycle command; prepares the device for a OTP REG-
ISTER or LOCK REGISTER PROGRAM operation. The second cycle latches
the register address and data, and starts the programming algorithm
to program data the OTP array.
Configuration Read configuration
register setup
0x60
0x03
First cycle of a two-cycle command; prepares the CUI for device read
configuration. If the SET READ CONFIGURATION REGISTER command
(0x03) is not the next command, the CUI sets status register bits SR4
and SR5, indicating a command sequence error.
Read configuration
register
If the previous command was READ CONFIGURATION REGISTER SETUP
(0x60), the CUI latches the address and writes A[16:1] to the read con-
figuration register for Easy BGA and TSOP, A[15:0] for QUAD+. Follow-
ing a CONFIGURE READ CONFIGURATION REGISTER command, subse-
quent READ operations access array data.
