Legend:
X = Don’t care
RA = Address of the memory location 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 rising edge of the AVD# pulse or active edge of CLK which ever
comes first.
PD = Data to be programmed at location PA. Data latches on the rising edge of WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits Amax–A12 uniquely select any sector.
BA = Address of the bank (WS128J: A22, A21, A20, WS064J: A21, A20, A19) that is being switched to autoselect mode, is in bypass mode, or is
being erased.
SLA = Address of the sector to be locked. Set sector address (SA) and either A6 = 1 for unlocked or A6 = 0 for locked.
SBA = sector address block to be protected.
CR = Configuration Register address bits A19–A12.
OW = Address (A7–A0) is (00011010).
PD3–PD0 = Password Data. PD3–PD0 present four 16 bit combinations that represent the 64-bit Password
PWA = Password Address. Address bits A1 and A0 are used to select each 16-bit portion of the 64-bit entity.
PWD = Password Data.
PL = Address (A7-A0) is (00001010)
RD(0) = DQ0 protection indicator bit. If protected, DQ0 = 1, if unprotected, DQ0 = 0.
RD(1) = DQ1 protection indicator bit. If protected, DQ1 = 1, if unprotected, DQ1 = 0.
SL = Address (A7-A0) is (00010010)
WD= Write Data. See “Configuration Register” definition for specific write data
WP = Address (A7-A0) is (00000010)
WPE = address(A7-A0) is (01000010)
Notes:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the following, all bus cycles are write cycle: read cycle, fourth through sixth cycles of the Autoselect commands, fourth cycle of
the configuration register verify and password verify commands, and any cycle reading at RD(0) and RD(1).
4. Data bits DQ15–DQ8 are don’t care in command sequences, except for RD, PD, WD, PWD, and PD3-PD0.
5. Unless otherwise noted, address bits Amax–A12 are don’t cares.
6. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. The system
must write the reset command to return the device to reading array data.
7. No unlock or command cycles required when bank is reading array data.
8. The Reset command is required to return to reading array data (or to the erase-suspend-read mode if previously in Erase Suspend) when a
bank is in the autoselect mode, or if DQ5 goes high (while the bank is providing status information) or performing sector lock/unlock.
9. The fourth cycle of the autoselect command sequence is a read cycle. The system must provide the bank address. See the Autoselect
Command Sequence section for more information.
10. (BA)X0Fh = 2200h (WS128J), (BA)X0Eh = 2218h (WS128J), (BA)X0Fh = 221Eh (WS064J), (BA)X0Eh = 2201h (WS064J)
11. The data is 0000h for an unlocked sector and 0001h for a locked sector
12. DQ15 - DQ8 = 0, DQ7 - Factory Lock Bit (1 = Locked, 0 = Not Locked), DQ6 -Customer Lock Bit (1 = Locked, 0 = Not Locked), DQ5 =
Handshake Bit (1 = Reserved, 0 = Standard Handshake)8, DQ4 & DQ3 - Boot Code (00= Dual Boot Sector, 01= Top Boot Sector, 10=
Bottom Boot Sector, 11=No Boot Sector), DQ2 - DQ0 = 001
13. The Unlock Bypass command sequence is required prior to this command sequence.
