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 falling edge of the WE# or CE# pulse, whichever happens
later.
PD = Data to be programmed at location PA. Data latches on the rising edge of WE# or CE# pulse, whichever happens first.
PD(0) = Secured Silicon Sector Lock Bit. PD(0), or bit[0].
PD(3) = Protection Mode OTP Bit. PD(3) or bit[3].
SA = Address of the sector to be verified (in autoselect mode) or erased. SA includes BA. Address bits Amax - A13 uniquely select any sector.
BA = Address of the bank A21-A19.
CR = Configuration Register set by data bits D15-D0.
RD(0) = DQ0 protection indicator bit. If protected, DQ0 = 0, if unprotected, DQ0 = 1.
RD(1) = DQ1 protection indicator bit. If protected, DQ1 = 0, if unprotected, DQ1 = 1.
RD(2) = DQ2 protection indicator bit. If protected, DQ2 = 0, if unprotected, DQ2 = 1.
RD(4) = DQ4 protection indicator bit. If protected, DQ4 = 0, if unprotected, DQ4 = 1.
WBL = Write Buffer Location. Address must be within the same write buffer page as PA.
WC = Word Count. Number of write buffer locations to load minus 1.
Notes
1. See
Table 9.1 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the read cycle and the fourth cycle of the autoselect command sequence, all bus cycles are write cycles.
4. Data bits DQ15–DQ8 are don’t care in command sequences, except for RD and PD.
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).
9. The fourth cycle of the autoselect command sequence is a read cycle. The system must read device IDs across the 4th, 5th, and 6th
10.
See
Table 9.1 for description of bus operations.
12. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode. The Erase
Suspend command is valid only during a sector erase operation, and requires the bank address.
13. The Erase Resume command is valid only during the Erase Suspend mode, and requires the bank address.
