*Notice: Stresses beyond those listed under “Absolute
maximum ratings” may cause permanent damage
to the device. This is a stress rating only, and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.

X can be V IL or V IH .
Refer to programming characteristics.
V H = 12.0 ± 0.5V.
Two identifier bytes may be selected. All Ai inputs are held low (V IL ), except A 9 , which is set to V H , and A 0 ,
which is toggled low (V IL ) to select the manufacturer’s identification byte and high (V IH ) to select the device
code byte.
