Remarks 1.
The pin assignment of the EP-16000C (sold separately) is equivalent to that of the
27C4000/27C8000/27C16000, except for pin 32, which is an NC pin.
2.
The pin assignment of the EP-16384C (sold separately) is equivalent to that of the 27C4096 for
pins from 2 to 41, but pin 2 is an NC pin. Note that the pin assignments of pins 1 and 42 are
exclusive to the EP-16384C (sold separately).
