36 / 72 page  256-Mbit J3 (x8/x16) 36 Datasheet Clear Block Lock-Bits SCS 2 Write X 0x60 Write X 0xD0 1,15 Protection Program 2 Write X 0xC0 Write PA PD 1 NOTES: 1. Commands other than those shown above are reserved by Intel for future device implementations and should not be used. 2. The Basic Command Set (BCS) is the same as the 28F008SA Command Set or Intel Standard Command Set. The Scalable Command Set (SCS) is also referred to as the Intel Extended Command Set. 3. Bus operations are defined in Table 12. 4. X = Any valid address within the device. BA = Address within the block. IA = Identifier Code Address: see Table 17. QA = Query database Address. PA = Address of memory location to be programmed. RCD = Data to be written to the read configuration register. This data is presented to the device on A[16:1]; all other address inputs are ignored. 5. ID = Data read from Identifier Codes. QD = Data read from Query database. SRD = Data read from Status Register. See Table 18 for a description of the Status Register bits. PD = Data to be programmed at location PA. Data is latched on the rising edge of WE#. CC = Configuration Code. 6. The upper byte of the data bus (D[15:8]) during command writes is a “Don’t Care” in x16 operation. 7. Following the Read Identifier Codes command, read operations access manufacturer, device and block lock codes. See Section 10.2 for read identifier code data. 8. If the WSM is running, only D7 is valid; D[15:8] and D[6:0] float, which places them in a high-impedance state. 9. After the Write to Buffer command is issued check the XSR to make sure a buffer is available for writing. 10.The number of bytes/words to be written to the Write Buffer = N + 1, where N = byte/word count argument. Count ranges on this device for byte mode are N = 00H to N = 1FH and for word mode are N = 0x00 to N = 0x0F. The third and consecutive bus cycles, as determined by N, are for writing data into the Write Buffer. The Confirm command (0xD0) is expected after exactly N + 1 write cycles; any other command at that point in the sequence aborts the write to buffer operation. See Figure 18, “Write to Buffer Flowchart” on page 59 for additional information 11. The write to buffer or erase operation does not begin until a Confirm command (0xD0) is issued. 12.Attempts to issue a block erase or program to a locked block. 13.Either 0x40 or 0x10 are recognized by the WSM as the byte/word program setup. 14.Program suspends can be issued after either the Write-to-Buffer or Word/Byte-Program operation is initiated. 15.The clear block lock-bits operation simultaneously clears all block lock-bits.
