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 4 XXXH AAH XXXH 55H XXXH 90H ADI DDI Sector Protect 4 XXXH AAH XXXH 55H XXXH 90H (SA) 00H Verify x02H 01H Byte Program 4 XXXH AAH XXXH 55H XXXH A0H PA PD Chip Erase 6 XXXH AAH XXXH 55H XXXH 80H XXXH AAH XXXH 55H XXXH 10H Sector Erase 6 XXXH AAH XXXH 55H XXXH 80H XXXH AAH XXXH 55H SA 30H Sector Erase Suspend 1 XXXH B0H Sector Erase Resume 1 XXXH 30H CFI Query 1 XXXH 98 TABLE 4. MX29LV017B COMMAND DEFINITIONS Notes: 1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A20=do not care. (Refer to table 2) DDI = Data of Device identifier : C2H for manufacture code, C8H 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. 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. 4. Any number of CFI data read cycles are permitted. 5. The reset command is required to return to the read mode when the device is in the automatic select mode or if Q5 goes high. |
