Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 11.5–12.5 V, VHH = 9.0 ± 0.5 V, X = Don’t Care, SADD = Flash Sector Address, AIN =
Address In, DIN = Data In, DOUT = Data Out
Notes:
1. Other operations except for those indicated in this column are
inhibited.
2. Do not apply CE#f1 or 2 = VIL, CE#1ps = VIL and CE2ps = VIH at
the same time.
3. Don’t care or open LB#s or UB#s.
4. If WP#/ACC = VIL, 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 “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 “Sector/Sector Block
Protection and Unprotection”. If WP#/ACC = VHH, all sectors will
be unprotected.
7. Data will be retained in pSRAM.
8. Data will be lost in pSRAM.
9. Both CE#f1 inputs may be held low for this operation.
