• Manufacturer Part Number: S29GL128S
• Manufacturer: SPANSION [SPANSION]

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
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
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,
4. Data bits DQ15-DQ8 are don't care in command sequences, except for RD, PD, WC and PWD.
5. Address bits A
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
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.
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
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
15. All Lock Register bits are one-time programmable. The program state = 0 and the erase state = 1. Also, both the Persistent Protection
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
