Hi all,
I have discovered a 4-digit, 7-segment LCD (40-pin dip). I bought it about 30 years ago but I never use it. Now I have a little project in my mind and I think to use it with its driver (Maxim ICM7211).

Looking on the net I have found a picture of an LCD that seems very similar to mine (BZTN120701-11) but I have no idea about the electrical connection nor have I found any datasheet.

Can anyone suggest to me any idea?

Thank you in advance

Is that driver part of the LCD or do you mean to connect your LCD to a separate driver IC? IF the latter, how o you know the ICM7211 is the right driver if you do not have a datasheet for the LCD?

Is that the number of your LCD or of the similar one you found? Outer appearance can be very deceptive. We will need the part number of your LCD.

Show some photos of the device
The number you quoted brings up nothing.
