Product Overview: 24AA02E48T-I/OT - Microchip Technology

The 24AA02E48T-I/OT is a highly efficient, 2 Kbit Electrically Erasable PROM (EEPROM) with a built-in EUI-48™ Node Identity from the renowned manufacturer, Microchip Technology. Designed to provide a unique Ethernet MAC address for networked devices, this tiny, surface-mount, serial EEPROM is essential for applications requiring network connectivity and unique identification.

This device operates in the standard I²C bus, supporting a bidirectional data transfer protocol. Devices on the I²C bus can be either masters or slaves, with the 24AA02E48T-I/OT typically acting as a slave. The bus has to be controlled by a master device that generates the serial clock (SCL), controls the bus access, and generates the START and STOP conditions, while the 24AA02E48T-I/OT EEPROM stores data that can be accessed via the bus.

The 24AA02E48T-I/OT is designed for low-power applications, with a wide voltage range of 1.7V to 5.5V, making it suitable for various operating environments. Its low power consumption and small form factor (SOT-23 package) make it an ideal choice for portable and power-sensitive applications across diverse market segments.

The EEPROM comes with a pre-programmed EUI-48™ node address, eliminating the need for the end-user to program the MAC address. This feature simplifies design, enhances production efficiency, and ensures that each device can be uniquely identified on a network. The product also features a write protect pin to prevent inadvertent writes, thereby securing the stored data.

With a high endurance of one million write cycles and a data retention period of over 200 years, the 24AA02E48T-I/OT promises reliability and longevity. These characteristics, along with its extended temperature range (-40°C to +85°C), make it a robust choice for industrial, automotive, and consumer applications where stable operation under varying conditions is required.

In summary, Microchip's 24AA02E48T-I/OT EEPROM is a highly reliable and versatile component, perfect for networked devices requiring unique identification, low-power operation, and long-term data integrity.
