Data Sheet
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.
PD = Data to be programmed at location PA.
SA = Address of the sector selected. Address bits A
MAX
-A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same Line.
WC = Word Count is the number of write buffer locations to load minus 1.
PWAx = Password address for word0 = 00h, word1 = 01h, word2 = 02h, and word3 = 03h.
PWDx = Password data word0, word1, word2, and word3.
Notes:
1. See Table 8.1, Interface States on page 67 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the following, all bus cycles are write cycle: read cycle during Read, ID/CFI Read (Manufacturing ID / Device ID), Indicator Bits,
Secure Silicon Region Read, SSR Lock Read, and 2nd cycle of Status Register Read .
4. Data bits DQ15-DQ8 are don't care in command sequences, except for RD, PD, WC and PWD.
5. Address bits A
MAX
-A11 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 ID-CFI (autoselect) mode, or if DQ5 goes High
(while the device is providing status data).
8. Command is valid when device is ready to read array data or when device is in ID-CFI (autoselect) mode.
9. The system can read and program/program suspend in non-erasing sectors, or enter the ID-CFI ASO, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase operation.
10. The Erase Resume/Program Resume command is valid only during the Erase Suspend/Program Suspend modes.
11. Issue this command sequence to return to READ mode after detecting device is in a Write-to-Buffer-Abort state. IMPORTANT: the full
command sequence is required if resetting out of ABORT.
12. The Exit command returns the device to reading the array.
13. The password portion can be entered or read in any order as long as the entire 64-bit password is entered or read.
14. For PWDx, only one portion of the password can be programmed per each A0 command. Portions of the password must be programmed
in sequential order (PWD0 - PWD3).
15. All Lock Register bits are one-time programmable. The program state = 0 and the erase state = 1. Also, both 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 are undefined and may be 0’s or
1's.
16. If any of the Entry commands was issued, an Exit command must be issued to reset the device into read mode.
17. Protected State = 00h, Unprotected State = 01h. The sector address for DYB set, DYB clear, or PPB Program command may be any
location within the sector - the lower order bits of the sector address are don't care.
