-55/-70/-90
To verify programming of the protection circuitry, the programming equipment must force V
ID
on address pin A
9
with CE and OE at V
IL
and WE at V
IH
. Scanning the sector addresses (A
16
, A
17
and A
18
) while (A
6
, A
1
, A
0
) = (0,
1, 0) will produce a logical “1” code at device output DQ
0
for a protected sector. Otherwise the device will read
00H for unprotected sector. In this mode, the lower order addresses, except for A
0
, A
1
and A
6
are DON’T CARES.
Address locations with A
1
= V
IL
are reserved for Autoselect manufacturer and device codes.
It is also possible to determine if a sector is protected in the system by writing an Autoselect command. Performing
a read operation at the address location XX02H, where the higher order addresses (A
16
, A
17
and A
18
) are the
sector address will produce a logical “1” at DQ
0
for a protected sector. See Table 3 for Autoselect codes.
Notes:
1.Address bits A
11
to A
18
= X = “H” or “L” for all address commands except for Program Address (PA) and
Sector Address (SA).
2.Bus operations are defined in Table 2.
3.RA = Address of the memory location to be read.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of the
WE pulse.
SA = Address of the sector to be erased. The combination of A
18
, A
17
, and A
16
will uniquely select any
sector.
4.RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the falling edge of WE.
*: Either of the two reset commands will reset the device.
Command Definitions
Device operations are selected by writing specific address and data sequences into the command register.
Writing incorrect address and data values or writing them in the improper sequence will reset the device to 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. Moreover, both Read/
Reset Commands are functionally equivalent, resetting the device to the read mode.
