24LC01B/SN – MICROCHIP TECHNOLOGY

Overview

The Microchip Technology 24LC01B/SN is a 1Kbit I2C serial EEPROM designed for non-volatile data storage in embedded systems. Its primary function is to provide reliable, byte-addressable memory for configuration parameters, calibration data, or small lookup tables. A critical operational characteristic is its 400 kHz I2C interface, enabling efficient data transfer. However, designers must carefully consider the 5ms page write cycle time, which can significantly impact system responsiveness during frequent write operations, necessitating careful firmware management to avoid performance bottlenecks.

Key Features

• Memory Size: 1Kbit (128 x 8)
• Interface: I2C (400 kHz)
• Access Time: 3.5 µs
• Voltage Range: 2.5V to 5.5V
• Operating Temperature: -40°C to 85°C
• Package: 8-SOIC (3.90mm width)

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 calibration coefficients for sensor modules.
• Holding device identification and serial numbers in IoT devices.
• Implementing small configuration registers for peripheral devices.
• Providing persistent state storage for low-power microcontrollers.
