Table 1.
Device Bus Operations—Flash Word Mode, CIOf = V
IH; CC SRAM Word Mode, CIOs = VCC
Legend: L = Logic Low = V
IL, H = Logic High = VIH, VID = 11.5–12.5 V, VHH = 9.0 ± 0.5 V, X = Don’t Care, SA = CC SRAM
Address Input, Byte Mode, SADD = Flash Sector Address, A
IN = Address In, DIN = Data In, DOUT = Data Out, CC =
CompactCell
TM
Notes:
1. Other operations except for those indicated in this column are inhibited.
2. Do not apply CE#f = V
IL, 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 = V
ACC (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 = V
IL, 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 = V
HH, all sectors will be unprotected.
