A 333 KB PDF datasheet for the 24AA16 and 24LC16B, 16 Kbit serial EEPROMs using the I2C bus. These parts are organised as several internal blocks selected through the address byte, a detail that matters when choosing the device type in programmer software. The document gives pin assignment, supply range, page write size and timing. Use it to check SDA, SCL and power at the chip or to set up a read. Confirm the marking on the package and save the original data to a file before reprogramming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
