AT24CM01-SSHD-T: A 1-Mb Serial EEPROM for Demanding Applications

The AT24CM01-SSHD-T is a high-density 1-Megabit (128-Kbyte) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device designed to provide reliable non-volatile data storage for a wide range of electronic systems. Operating from a single 1.7V to 3.6V power supply, it is an ideal solution for portable, battery-powered devices where low power consumption and space savings are critical.

This EEPROM utilizes the ubiquitous and efficient two-wire I²C serial interface, supporting a maximum clock frequency of 1MHz for fast data transfer. Its architecture is organized as 131,072 words of 8 bits each, providing flexible byte-level and page-level read/write capabilities. A key feature of this device is its exceptional endurance, capable of supporting over 4 million write cycles, far exceeding the capabilities of standard Flash memory. This makes it perfect for applications that require frequent updates to stored data. Furthermore, it boasts an impressive data retention period of over 100 years, ensuring long-term integrity of critical information.

The integration of a hardware write-protect pin adds a crucial layer of security, allowing the host system to prevent any accidental modifications to the stored data. The device is also specified for extended industrial temperature ranges (-40°C to +85°C), ensuring reliable operation in harsh environments.

Applications of the AT24CM01-SSHD-T are diverse and critical. It is extensively used for storing system configuration parameters, calibration data, and user settings in everything from industrial automation and medical equipment to smart meters and networking hardware. In the consumer electronics space, it serves in smart TVs, set-top boxes, and printers. Its high density also makes it suitable for storing event logs, serial numbers, and other data that must be preserved through power cycles.

ICGOODFIND: The AT24CM01-SSHD-T stands out as a robust, high-density, and highly reliable serial EEPROM solution. Its combination of a standard I²C interface, superior endurance, long-term data retention, and hardware security features makes it an excellent choice for designers who need dependable non-volatile memory for advanced applications.
