The 24AA02E48T-I/OT is a Memory IC manufactured by Microchip. It is an EEPROM (Electrically-Erasable Programmable Read-Only Memory) that uses the I2C (Inter-Integrated Circuit) communication protocol to read, write, and erase data stored in its 2x128x8bit (2KB) of memory. This IC operates on voltage levels between 1.7V and 5.5V and has a maximum speed of 400kHz when running in the I2C mode. This IC is packaged in an SOT23-5 (Small Outline Transistor) package.
