24LC02B-I/SN – MICROCHIP TECHNOLOGY

Overview

The Microchip Technology 24LC02B-I/SN is a 2 kbit serial EEPROM designed for reliable non-volatile data storage in embedded systems. Its primary function is to provide persistent storage for configuration parameters, calibration data, or small lookup tables, accessible via the industry-standard 2-Wire (I2C) interface. A critical design consideration for this device is the trade-off between access speed and power consumption; while the 400 kHz maximum clock frequency offers reasonable data throughput, designers must carefully manage bus loading and signal integrity to avoid read/write errors, especially in noisy environments or when interfacing with multiple devices on the same bus.

Key Features

• Memory Size: 2 kbit (256 x 8 bit organization)
• Interface Type: 2-Wire (I2C) compatible
• Maximum Clock Frequency: 400 kHz
• Supply Voltage Range: 2.5 V to 5.5 V
• Data Retention: 200 years
• Package: SOIC-8 (4.9mm x 3.9mm x 1.25mm)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Storing device unique identifiers (UIDs) in IoT nodes
• Configuration data persistence for industrial control modules
