In the future I will do many of these circuits, however I haven’t yet decided if I need the full 32KB of memory.

For memory chips in particular, pins that get used as address pins in larger parts and are NC pins datashheet smaller parts can usually be datwsheet. After looking at the datasheets, I notice the difference in pin-out between the two chips is that on the AT28C64, A13 and A14 are replaced with NC no connects.

Well no connect could mean do not connect or does not connect. Sign up using Email and Password. Sign up or log in Sign up using Google.

I created a circuit in which all the address inputs of an AT28C are connected to outputs of shift registers 74HC Home Questions Tags Users Unanswered. The datasheet of the AT28C64 makes it pretty clear: Is it OK anyway to connect such pins to outputs of shift registers and be able to make a AT28C64 like a drop-in replacement for AT28C af28c64 are the NC pins internally dtasheet to something? With that resistor in series with pin 1, swapping in an 8K ROM instead of the 32K one should work just fine.

In general, except in cases where the manufacture is specifically supporting compatible footprints between different parts, you should not connect to the NC datashfet.

Sometimes no connect pins are special function pins and they don’t want you dafasheet connect to them.

That’s the obvious part.

They can usually answer these types of questions. Email Required, but never shown. Other times there may not even be a wire bond between the silicon and the pin, so you are datwsheet to do whatever you want with it.

There are “No Connect” NC pins, those are not connected in the chip so you can hook them up to a voltage.
