10 / 63 page  10 P/N:PM1041 MX29LV160BT/BB REV. 1.2, JUL. 01, 2004 R in the improper sequence will reset the device to the read mode. Table 5 defines the valid register command sequences. Note that the Erase Suspend (B0H) and Erase Resume (30H) commands are valid only while the Sector Erase operation is in progress. COMMAND DEFINITIONS Device operations are selected by writing specific ad- dress and data sequences into the command register. Writing incorrect address and data values or writing them First Bus Second Bus Third Bus Fourth Bus Fifth Bus Sixth Bus Command Bus Cycle Cycle Cycle Cycle Cycle Cycle Cycle Addr Data Addr Data Addr Data Addr Data Addr Data Addr Data Reset 1 XXXH F0H Read 1 RA RD Read Silicon ID Word 4 555H AAH 2AAH 55H 555H 90H ADI DDI Byte 4 AAAH AAH 555H 55H AAAH 90H ADI DDI Sector Protect Word 4 555H AAH 2AAH 55H 555H 90H (SA) XX00H Verify x02H XX01H Byte 4 AAAH AAH 555H 55H AAAH 90H (SA) 00H x04H 01H Program Word 4 555H AAH 2AAH 55H 555H A0H PA PD Byte 4 AAAH AAH 555H 55H AAAH A0H PA PD Chip Erase Word 6 555H AAH 2AAH 55H 555H 80H 555H AAH 2AAH 55H 555H 10H Byte 6 AAAH AAH 555H 55H AAAH 80H AAAH AAH 555H 55H AAAH 10H Sector Erase Word 6 555H AAH 2AAH 55H 555H 80H 555H AAH 2AAH 55H SA 30H Byte 6 AAAH AAH 555H 55H AAAH 80H AAAH AAH 555H 55H SA 30H Sector Erase Suspend 1 XXXH B0H Sector Erase Resume 1 XXXH 30H CFI Query Word 1 55H 98 Byte AAH TABLE 5. MX29LV160BT/BB COMMAND DEFINITIONS Note: 1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A19=do not care. (Refer to table 3) DDI = Data of Device identifier : C2H for manufacture code, C4H/49H (x8) and 22C4H/2249H (x16) for device code. X = X can be VIL or VIH RA=Address of memory location to be read. RD=Data to be read at location RA. 2.PA = Address of memory location to be programmed. PD = Data to be programmed at location PA. SA = Address of the sector to be erased. 3.The system should generate the following address patterns: 555H or 2AAH to Address A10~A0 in word mode/AAAH or 555H to Address A10~A-1 in byte mode. Address bit A11~A19=X=Don't care for all address commands except for Program Address (PA) and Sector Address (SA). Write Sequence may be initiated with A11~A19 in either state. 4. For Sector Protect Verify operation: If read out data is 01H, it means the sector has been protected. If read out data is 00H, it means the sector is still not being protected. 5. Any number of CFI data read cycles are permitted. |
