Visão Geral
Description
The EEPROM communicates via an I2C (Inter-Integrated Circuit) bus, a widely used protocol that allows communication with multiple devices using only two wires (SDA for data and SCL for clock). The 24AA02E48-I/SN is also noted for its unique 48-bit MAC (Media Access Control) address feature, which is globally unique and can be used for networking applications requiring MAC addresses.
Operating voltage ranges from 1.7V to 5.5V, making it suitable for a variety of applications. It also features low power consumption, making it ideal for battery-operated devices. The device comes in an 8-lead SOIC (Small Outline Integrated Circuit) package.
