*1: This command is valid while Fast Mode.

*2: This command is valid while RESET = V

ID

.

*3: The valid addresses are A

6

to A

0

.

*4: This command is valid while Hi-ROM mode.

Note:1. Address bits = X = “H” or “L” for all address commands except or 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 write pulse.

SA = Address of the sector to be erased. The combination of A

21

, A

20

, A

19

, A

18

, A

17

,A

16

, and A

15

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 write pulse.

5.SPA = Sector group address to be protected. Set sector group address (SGA) and (A

6

, A

1

, A

0

) = (0, 1, 0).

SD = Sector group protection verify data. Output 01h at protected sector group addresses and output

00h at unprotected sector group addresses.

6.Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
