Datasheet PDF, 83.7 KB, for the 24C01 serial EEPROM, a 1 Kbit (128-byte) memory on the two-wire I2C bus. The name gives no device or board context. Repair use centres on confirming the pinout, SDA and SCL positions, write-protect pin and voltage range before reading the part with a programmer. These chips keep settings, counters and identification data. A failed or interrupted write can corrupt them, so dump and store the original contents before any change and verify the chip type selected in software.
