Small PDF, 73 KB, documenting the 24LC01B, a 1 Kbit I2C serial EEPROM, the smallest common member of the 24LC family. Catalogued under schematics, it is in practice a component datasheet covering pinout, memory organisation, byte and page write timing and electrical characteristics. Such tiny EEPROMs store identifiers and settings in consumer electronics. Use it to confirm pin functions when tracing the bus, checking supply voltage or replacing the chip, and to set the right device in a programmer. Read the original contents first.
