/CE hardwired to ground - EEPROM

[atferrari]

There is a design with little more than a micro and an EEPROM whose data is already burnt in. Data is being read at regular pace.

In order to get the extra IO pin I need, I considered to hardwire the EEPROM's /CE pin to ground.

Is that objectionable?

In case you ask, no, human life does not depend of this design. (Maybe just my self-esteem).

The /CE input is usually used to enable individual memory chips when there are several chips connected in parallel to the same address and data lines.

So, if you only have one memory chip, I think that permamentlt enabling it will be ok.

If you only have the one chip then you can safely tie /CE and /OE to ground.

Gracias for the replies. Thinking of adding /WE to the combo!

Duly asserted, of course.
