Notes:
1. Other operations except for those indicated in this column are inhibited.
2. Do not apply CE#f = V
IL
, CE1#s = V
IL
and CE2s = V
IH
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 = V
IH
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”.
6. If WP#/ACC = V
IL
, the two outermost boot sectors remain protected. If WP#/ACC = V
IH
, 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.
Word/Byte Configuration
The CIOf pin controls whether the device data I/O pins
operate in the byte or word configuration. If the CIOf
pin is set at logic ‘1’, the device is in word configura-
tion, DQ15–DQ0 are active and controlled by CE#f
and OE#.
If the CIOf pin is set at logic ‘0’, the device is in byte
configuration, and only data I/O pins DQ7–DQ0 are
active and controlled by CE#f and OE#. The data I/O
pins DQ14–DQ8 are tri-stated, and the DQ15 pin is
used as an input for the LSB (A-1) address function.
Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE#f and OE# pins to V
IL
. CE#f is the power
control and selects the device. OE# is the output con-
trol and gates array data to the output pins. WE#
should remain at V
IH
. The CIOf pin determines
whether the device outputs array data in words or
bytes.
