Electronic – Help Identifying a chip from a schlage handkey board

From the aspect of the width vs height, it looks like something like a 160 x 128 pixel cog display. A 128 x 64 would have a close to 2:1 aspect ratio. This ratio is much closer. These are available as standard modules. Look at LCD vendor specs on line for one these modules and check the number of traces on the flex. These all use similar LCD driver ICs that have a long narrow profile. The pinouts are all similar because all of the row and column driver outputs have to come off the IC and be routed to rows and columns on the bottom glass. The glass substrate is a single sided PCB of sorts.

These drivers typically have both a 8 bit parallel and a serial interface, as well as RW, CE, and MODE pins. There are several pins that require external capacitors for the on board negative bias charge pumps.

I just found a project on github, that uses an arduino to read and write the EEPROM of Stratasys Cartidges. Theres a UI to set whatever values you want to the EEPROM: https://github.com/slaytonrnd/CartridgeWriter
