word-/byte-mode configuration
The BYTE pin is used to set the device configuration. If BYTE is at a logic 1, the device is in word mode with
all data outputs valid and the DQ15/A
–1
output representing DQ15. Similarly, if BYTE is at a logic 0, the device
is in byte mode with only DQ0–DQ7 valid. The remaining outputs are in high-impedance mode and DQ15/A
–1
is used as an input for the least significant bit (A1) address function. See Figure 3 and Figure 4 for timing
specifications.

temporary hardware-sector unprotect feature
This feature temporarily enables both programming and erase operations on any combination of one to nineteen
sectors that were previously protected. The unprotect feature is enabled using high voltage V
ID
(11.5 V to
12.5 V) on the RESET pin, using standard command sequences.
Normally, the device is delivered with all sectors unprotected.
