The AT93C46/56/57/66 is enabled through the Chip Select
pin (CS), and accessed via a 3-wire serial interface consist-
ing of Data Input (DI), Data Output (DO), and Shift Clock
(SK). Upon receiving a READ instruction at DI, the address
is decoded and the data is clocked out serially on the data
output pin DO. The WRITE cycle is completely self-timed
and no separate ERASE cycle is required before WRITE.
The WRITE cycle is only enabled when the part is in the

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age 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
