datasheet NOR FLASH MEMORY
NOTE :
• RA : Read Address, PA : Program Address, RD : Read Data, PD : Program Data, WBL : Write Buffer Location
• BA : Block Address (A16 - A22), ABP : Address of the block to be protected or unprotected, X = Don’t care .
• DQ8 - DQ15 are don’t care in command sequence, except for RD and PD
• A14 - A22 are also don’t care, except for the case of special notice.
• WC = Word Count. Number of write buffer locations to load minus 1.
• PWA3 ~ PWA0 = Password Address. PWD3 ~ PWD0 = Password Data.
PD3 ~ PD0 present four 16 bit combinations that represent the 64-bit Password
• RD(0) = DQ0 protection indicator bit. If protected, DQ0 = 0, if unprotected, DQ0 = 1.
1) See bus operations description
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, 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 PWD3 ~ PWD0.
5) Unless otherwise noted, these address bits are don’t cares: (A22 ~ A14)
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 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 the deviceis in the autoselect
mode, or if DQ5 goes high (while the device is providing status information) or performing block lock/unlock.
9) The fourth cycle of the autoselect command sequence is a read cycle. See Autoselect.
10) The data is 0000h for an unlocked block and 0001h for a locked block.
11) Device ID data : X0EH = "2266H", X0FH = "2260H" for 128Mb Uniform Block Device
12) See Autoselect.
13) The Unlock Bypass command sequence is required prior to this command sequence.
14) The Unlock Bypass Reset command is required to return to reading array data when the device is in the unlock bypass mode.The system may read and program in non-
erasing blocks, or enter the autoselect mode, when in the Erase Suspend mode. The Erase Suspend command is valid only during a block erase operation.
15) The Erase Resume command is valid only during the Erase Suspend mode.
16) Command is valid when device is ready to read array data or when device is in autoselect mode.The total number of cycles in the command sequence is determined by the
number of words written to the write buffer. The maximum number of cycles in the command sequence is 37.
17) The entire four bus-cycle sequence must be entered for which portion of the password.
18) The Unlock Bypass Reset command is required to return to reading array data when the device is in the unlock bypass mode.The system may read and program in non-
erasing blocks, or enter the autoselect mode, when in the Erase Suspend mode. The Erase Suspend command is valid only during a block erase operation.
19) The Erase Resume command is valid only during the Erase Suspend mode.
20) Command is valid when device is ready to read array data or when device is in autoselect mode.The total number of cycles in the command sequence is determined by the
number of words written to the write buffer. The maximum number of cycles in the command sequence is 37.
21) The entire four bus-cycle sequence must be entered for which portion of the password.
22) The ALL PPB ERASE command pre-programs all PPBs before erasure to prevent over-erasure of PPBs.
23) WP/ACC must be at VHH during the entire operation of this command.
24) Command sequence resets device for next command after write-to-buffer operation.
25) Entry commands are needed to enter a specific mode to enable instructions only available within that mode.
26) If both the Persistent Protection Mode Locking Bit and the password Protection Mode Locking Bit are set a the same time, the command operation aborts and returns the
device to the default Persistent block Protection Mode.
27) The Exit command must be issued to reset the Block 0 of device into read mode. Otherwise the device hangs.
28) The Exit command must be issued to reset device into read mode. Otherwise the device hangs.
