*1: This command is valid while Fast Mode.
*2: This command is valid while RESET=V
ID
.
*3: This data "00H" is also acceptable.
Notes:
1. Address bits A
12
to A
18
= X = “H” or “L” for all address commands except or Program Address (PA), Sector
Address (SA), and Bank Address (BA).
2. Bus operations are defined in Tables 2 and 3.
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 write pulse.
SA = Address of the sector to be erased. The combination of A
18
, A
17
, A
16
, A
15
, A
14
, A
13
, and A
12
will
uniquely select any sector.
BA = Bank Address (A
16
to A
18
)
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 write pulse.
5. SPA =Sector address to be protected. Set sector address (SA) and (A
6
, A
1
, A
0
) = (0, 1, 0).
SD = Sector protection verify data. Output 01H at protected sector addresses and output 00H at
unprotected sector addresses.
6. The system should generate the following address patterns:
Word Mode: 555H or 2AAH to addresses A
0
to A
11
Byte Mode: AAAH or 555H to addresses A
–1
and A
0
to A
11
7. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
