Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 11.512.5 V, VHH = 9.0 ± 0.5 V, X = Dont Care, SA = pSRAM Address Input, Byte Mode,  
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.  
5. The sector protect and sector unprotect functions may also be  
implemented via programming equipment. See the Autoselect  
Modesection.  
2. Do not apply CE#f = VIL, CE1#s = VIL and CE2s = VIH at the same  
time.  
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 Autoselect Mode. If  
WP#/ACC = VHH, all sectors will be unprotected.  
3. Dont 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%.  
7. Data will be retained in pSRAM.  
8. Data will be lost in pSRAM.
