PDF of 146 KB that groups several part numbers in its name: 24C02, C02R and W02, apparently related 2 Kbit (256-byte) I2C EEPROM variants covered in one datasheet. The name does not say what distinguishes the R and W variants, so read the document itself for differences in write protection or packaging. No device or board is stated. Useful for matching a marked chip to the right type in programmer software, and the original contents should be dumped and kept before any write.
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.
