Description
English: This is a re-shoot of an old chip I opened up previously. I knew at the time that I could only see the metal layers and I needed a metallurgical scope to see anything else, so here we are.

Thanks to the improved camera and scope I can make out smaller details. According to the datasheet this chip has 128 Bytes of onboard SRAM and there are 32 rows and 32 columns in the mid-right block which equates to 1024 bits or 128 Bytes. Because of this I am fairly confident that block is the SRAM and the other two are the ROM.

This was pulled from an old opto-mechanical mouse which used a serial RS-232 connector. The top of the mouse and the ball were missing, so I was unable to identify the model. I think it is made by Logitech since the package has that written on it.

It was designed in 1988 and it uses HCMOS and It was based off of the Motorola 6800.
