PDF of 306 KB for the 24C04 serial EEPROM, with a P suffix that the name leaves unexplained. A 24C04 holds 4 Kbit (512 bytes) split into two 256-byte blocks selected through the device address, a detail the datasheet explains. These small memories keep settings in TVs, monitors, printers and appliances. Use the sheet to locate pin 1, the I2C lines and the write-protect pin before connecting a programmer, and keep a dump of the original data in case a write fails.
