Table 3.

Device Bus Operations—Flash Byte Mode, CIOf = V

SS; SRAM Word Mode, CIOs = VCC

Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 8.5–12.5 V, VHH = 9.0 ± 0.5 V, X = Don’t Care, SA = SRAM Address

Input, Byte Mode, SADD = Flash Sector Address, AIN = Address In (for Flash Byte Mode, DQ15 = A-1), DIN = Data In, DOUT =

Data Out

Notes:

1. Other operations except for those indicated in this column are inhibited.

2. Do not apply CE#f = VIL, CE1#s = VIL and CE2s = VIH at the same time.

3. Don’t care or open LB#s or UB#s.

4. If WP#/ACC = V

IL , the boot sectors will be protected. If WP#/ACC = VIH the boot sectors protection will be removed.

If WP#/ACC = VACC (9V), the program time will be reduced by 40%.

5. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “The autoselect

mode provides manufacturer and device identification, and sector protection verification, through identifier codes output on

DQ7–DQ0. The autoselect codes can be accessed in-system through the command register. Refer to the Autoselect Command

Sequence section for more information.Sector/Sector Block Protection and Unprotection” section.

6. If WP#/ACC = VIL, the two outermost boot sectors remain protected. If WP#/ACC = VIH, the two outermost boot sector protection

depends on whether they were last protected or unprotected using the method described in “The autoselect mode provides

manufacturer and device identification, and sector protection verification, through identifier codes output on DQ7–DQ0. The

autoselect codes can be accessed in-system through the command register. Refer to the Autoselect Command Sequence section

for more information.Sector/Sector Block Protection and Unprotection”. If WP#/ACC = VHH, all sectors will be unprotected.
