Legend
X = Don’t care
RD(0) = Read data.
SA = Sector Address. Address bits A
max
–A16 uniquely select any sector.
PWD = Password
Notes
1. See
Table 7.1 on page 19
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. All Lock Register bits are one-time programmable. Program state = “0” and
the erase state = “1.” The Persistent Protection Mode Lock Bit and the
Password Protection Mode Lock Bit cannot be programmed at the same
time or the Lock Register Bits Program operation aborts and returns the
device to read mode. Lock Register bits that are reserved for future use
default to “1’s.” The Lock Register is shipped out as “FFFF’s” before Lock
Register Bit program execution.
PWD
x
= Password word0, word1, word2, and word3.
Data = Lock Register Contents: PD(0) = Secured Silicon Sector Protection Bit,
PD(1) = Persistent Protection Mode Lock Bit, PD(2) = Password Protection
Mode Lock Bit.
7. The Exit command returns the device to reading the array.
8. If any Command Set Entry command was written, an Exit command must
be issued to reset the device into read mode.
9. For PWDx, only one portion of the password can be programmed per each
“A0” command.
10.Note that the password portion can be entered or read in any order as long
as the entire 64-bit password is entered or read.
11.If ACC = V
HH
, sector protection matches when ACC = V
IH
.
12.Protected State = “00h,” Unprotected State = “01h.”
13.The All PPB Erase command embeds programming of all PPB bits before
erasure.
