AT24CM01 Overview

The AT24CM01 provides 1,048,576 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 131,072 words of eight bits each. The device's cascading feature allows up to four devices to share a common two-wire bus. This device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential. The device is available in space-saving 8-lead SOIC, 8-Lead TSSOP, 8-Lead SOIJ and 8-ball WLCSP packages. All packages operate from 1.7V to 5.5V. The AT24CM01 operates as a slave device and utilizes a simple I2C-compatible two-wire digital serial interface to communicate with a host controller, commonly referred to as the bus master.

This article provides you with a basic overview of the AT24CM01 Serial EEPROM, including its pin descriptions, features and specifications, etc., to help you quickly understand what AT24CM01 is.
