The Intersil X24C01SI-3.5T3 is a 1Kbit CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) device with a 2-wire serial interface (I2C). It is organized as 128 bytes x 8 bits and provides non-volatile storage. The "-3.5" signifies a specific operating voltage, in this case, likely 3.5V. The "SI" likely indicates a SOIC package and potentially an industrial temperature range. The "T3" usually denotes tape and reel packaging or a specific manufacturing lot/revision.
